Saya memiliki onActivityResultpengembalian dari pemilihan gambar mediastore yang saya bisa mendapatkan URI untuk gambar menggunakan yang berikut:

Uri selectedImage = data.getData();

Mengubah ini menjadi string memberikan ini:

content://media/external/images/media/47

Atau ke jalan memberikan:

/external/images/media/47

Namun saya tidak bisa menemukan cara untuk mengubahnya menjadi jalur absolut, karena saya ingin memuat gambar ke dalam bitmap tanpa harus menyalinnya di suatu tempat. Saya tahu ini bisa dilakukan dengan menggunakan URI dan penyelesai konten, tetapi ini sepertinya MediaStoreberhenti saat me-reboot ponsel, saya kira tidak menjaga penomorannya tetap sama di antara reboot.

Di bawah API 19 gunakan kode ini untuk mendapatkan Jalur File dari URI:

public String getRealPathFromURI(Context context, Uri contentUri) {
  Cursor cursor = null;
  try { 
    String[] proj = { MediaStore.Images.Media.DATA };
    cursor = context.getContentResolver().query(contentUri,  proj, null, null, null);
    int column_index = cursor.getColumnIndexOrThrow(MediaStore.Images.Media.DATA);
    cursor.moveToFirst();
    return cursor.getString(column_index);
  } finally {
    if (cursor != null) {
      cursor.close();
    }
  }
}

Hanya pembaruan sederhana pada jawaban pertama: mActivity.managedQuery()sekarang sudah usang. Saya telah memperbarui kode dengan metode baru.

private String getRealPathFromURI(Uri contentUri) {
    String[] proj = { MediaStore.Images.Media.DATA };
    CursorLoader loader = new CursorLoader(mContext, contentUri, proj, null, null, null);
    Cursor cursor = loader.loadInBackground();
    int column_index = cursor.getColumnIndexOrThrow(MediaStore.Images.Media.DATA);
    cursor.moveToFirst();
    String result = cursor.getString(column_index);
    cursor.close();
    return result;
}

Untuk Oreo

Uri uri = data.getData(); 
File file = new File(uri.getPath());//create path from uri
final String[] split = file.getPath().split(":");//split the path.
filePath = split[1];//assign it to a string(your choice).

Untuk Semua versi di bawah Oreo saya telah membuat metode ini yang mendapatkan jalur nyata dari uri

 @SuppressLint("NewApi")
    public static String getFilePath(Context context, Uri uri) throws URISyntaxException {
        String selection = null;
        String[] selectionArgs = null;

          if (isGooglePhotosUri(uri)) {
              return uri.getLastPathSegment();
           }

            String[] projection = {
                    MediaStore.Images.Media.DATA
            };
            Cursor cursor = null;
            try {
                cursor = context.getContentResolver()

    }

    public static boolean isExternalStorageDocument(Uri uri) {
        return "com.android.externalstorage.documents".equals(uri.getAuthority());
    }

    public static boolean isDownloadsDocument(Uri uri) {
        return "com.android.providers.downloads.documents".equals(uri.getAuthority());
    }

    public static boolean isMediaDocument(Uri uri) {

    }

  public static boolean isGooglePhotosUri(Uri uri) {
    return "com.google.android.apps.photos.content".equals(uri.getAuthority());
}

Jangan mencoba mencari uri di sistem file, itu lambat untuk mencari di database.

Anda bisa mendapatkan bitmap dari uri dengan memberikan aliran input ke pabrik seperti Anda memberikan file ke pabrik:

InputStream is = getContentResolver().openInputStream(uri);
Bitmap bitmap = BitmapFactory.decodeStream(is);
is.close();

Ini dia contoh saya mendapatkan nama file, dari URI like file: // ... dan content: // .... Ini berfungsi bagi saya tidak hanya dengan Android MediaStore tetapi juga dengan aplikasi bagian ketiga seperti EzExplorer.

public static String getFileNameByUri(Context context, Uri uri)
{
    String fileName="unknown";//default fileName
    Uri filePathUri = uri;
    if (uri.getScheme().toString().compareTo("content")==0)
    {      
        Cursor cursor = context.getContentResolver().query(uri, null, null, null, null);
        if (cursor.moveToFirst())
        {
            int column_index = cursor.getColumnIndexOrThrow(MediaStore.Images.Media.DATA);//Instead of "MediaStore.Images.Media.DATA" can be used "_data"
            filePathUri = Uri.parse(cursor.getString(column_index));
            fileName = filePathUri.getLastPathSegment().toString();
        }
    }
    else if (uri.getScheme().compareTo("file")==0)
    {
        fileName = filePathUri.getLastPathSegment().toString();
    }
    else
    {
        fileName = fileName+"_"+filePathUri.getLastPathSegment();
    }
    return fileName;
}

Jawaban yang ada dan bagus, beberapa di antaranya saya gunakan untuk saya sendiri:

Saya harus mendapatkan jalur dari URI dan mendapatkan URI dari jalur, dan Google kesulitan membedakannya sehingga bagi siapa pun yang memiliki masalah yang sama (misalnya, untuk mendapatkan thumbnail dari MediaStorevideo yang lokasi fisiknya sudah Anda miliki ). Mantan:

/**
 * Gets the corresponding path to a file from the given content:// URI
 * @param selectedVideoUri The content:// URI to find the file path from
 * @param contentResolver The content resolver to use to perform the query.
 * @return the file path as a string
 */
private String getFilePathFromContentUri(Uri selectedVideoUri,
        ContentResolver contentResolver) {
    String filePath;
    String[] filePathColumn = {MediaColumns.DATA};

    Cursor cursor = contentResolver.query(selectedVideoUri, filePathColumn, null, null, null);
    cursor.moveToFirst();

    int columnIndex = cursor.getColumnIndex(filePathColumn[0]);
    filePath = cursor.getString(columnIndex);
    cursor.close();
    return filePath;
}

Yang terakhir (yang saya lakukan untuk video, tetapi juga dapat digunakan untuk Audio atau File atau jenis konten tersimpan lainnya dengan mengganti MediaStore.Audio (dll) untuk MediaStore.Video):

/**
 * Gets the MediaStore video ID of a given file on external storage
 * @param filePath The path (on external storage) of the file to resolve the ID of
 * @param contentResolver The content resolver to use to perform the query.
 * @return the video ID as a long
 */
private long getVideoIdFromFilePath(String filePath,
        ContentResolver contentResolver) {


    long videoId;
    Log.d(TAG,"Loading file " + filePath);

            // This returns us content://media/external/videos/media (or something like that)
            // I pass in "external" because that's the MediaStore's name for the external
            // storage on my device (the other possibility is "internal")
    Uri videosUri = MediaStore.Video.Media.getContentUri("external");

    Log.d(TAG,"videosUri = " + videosUri.toString());

    String[] projection = {MediaStore.Video.VideoColumns._ID};

    // TODO This will break if we have no matching item in the MediaStore.
    Cursor cursor = contentResolver.query(videosUri, projection, MediaStore.Video.VideoColumns.DATA + " LIKE ?", new String[] { filePath }, null);
    cursor.moveToFirst();

    int columnIndex = cursor.getColumnIndex(projection[0]);
    videoId = cursor.getLong(columnIndex);

    Log.d(TAG,"Video ID is " + videoId);
    cursor.close();
    return videoId;
}

Pada dasarnya, DATAkolom MediaStore(atau sub-bagian mana pun yang Anda tanyakan) menyimpan path file, jadi Anda bisa menggunakan apa yang Anda ketahui untuk mencari DATAbidang itu, atau menggunakan bidang untuk mencari apa pun yang Anda inginkan.

Saya kemudian lebih lanjut menggunakan Schemeseperti di atas untuk mencari tahu apa yang harus dilakukan dengan data saya:

 private boolean  getSelectedVideo(Intent imageReturnedIntent, boolean fromData) {

    Uri selectedVideoUri;

    //Selected image returned from another activity
            // A parameter I pass myself to know whether or not I'm being "shared via" or
            // whether I'm working internally to my app (fromData = working internally)
    if(fromData){
        selectedVideoUri = imageReturnedIntent.getData();
    } else {
        //Selected image returned from SEND intent 
                    // which I register to receive in my manifest
                    // (so people can "share via" my app)
        selectedVideoUri = (Uri)getIntent().getExtras().get(Intent.EXTRA_STREAM);
    }

    Log.d(TAG,"SelectedVideoUri = " + selectedVideoUri);

    String filePath;

    String scheme = selectedVideoUri.getScheme(); 
    ContentResolver contentResolver = getContentResolver();
    long videoId;

    // If we are sent file://something or content://org.openintents.filemanager/mimetype/something...
    if(scheme.equals("file") || (scheme.equals("content") && selectedVideoUri.getEncodedAuthority().equals("org.openintents.filemanager"))){

        // Get the path
        filePath = selectedVideoUri.getPath();

        // Trim the path if necessary
        // openintents filemanager returns content://org.openintents.filemanager/mimetype//mnt/sdcard/xxxx.mp4
        if(filePath.startsWith("/mimetype/")){
            String trimmedFilePath = filePath.substring("/mimetype/".length());
            filePath = trimmedFilePath.substring(trimmedFilePath.indexOf("/"));
        }

        // Get the video ID from the path
        videoId = getVideoIdFromFilePath(filePath, contentResolver);

    } else if(scheme.equals("content")){

        // If we are given another content:// URI, look it up in the media provider
        videoId = Long.valueOf(selectedVideoUri.getLastPathSegment());
        filePath = getFilePathFromContentUri(selectedVideoUri, contentResolver);

    } else {
        Log.d(TAG,"Failed to load URI " + selectedVideoUri.toString());
        return false;
    }

     return true;
 }

Tak satu pun dari jawaban ini bekerja untuk saya dalam semua kasus. Saya harus langsung membuka Dokumentasi Google https://developer.android.com/guide/topics/providers/document-provider.html tentang topik ini dan menemukan metode yang bermanfaat ini:

private Bitmap getBitmapFromUri(Uri uri) throws IOException {
    ParcelFileDescriptor parcelFileDescriptor =
    getContentResolver().openFileDescriptor(uri, "r");
    FileDescriptor fileDescriptor = parcelFileDescriptor.getFileDescriptor();
    Bitmap image = BitmapFactory.decodeFileDescriptor(fileDescriptor);
    parcelFileDescriptor.close();
    return image;
}

Anda dapat menggunakan bitmap ini untuk menampilkannya dalam Tampilan Gambar.

API 19 dan di atas , Path File Gambar dari Uri berfungsi dengan sempurna. Saya juga memeriksa PIE API 28 terbaru ini .

public String getImageFilePath(Uri uri) {
    String path = null, image_id = null;

    Cursor cursor = getContentResolver().query(uri, null, null, null, null);
    if (cursor != null) {
        cursor.moveToFirst();
        image_id = cursor.getString(0);
        image_id = image_id.substring(image_id.lastIndexOf(":") + 1);
        cursor.close();
    }

    Cursor cursor = getContentResolver().query(android.provider.MediaStore.Images.Media.EXTERNAL_CONTENT_URI, null, MediaStore.Images.Media._ID + " = ? ", new String[]{image_id}, null);
    if (cursor!=null) {
        cursor.moveToFirst();
        path = cursor.getString(cursor.getColumnIndex(MediaStore.Images.Media.DATA));
        cursor.close();
    }
    return path;
}

coba ini dapatkan jalur file gambar dari Uri

public void getImageFilePath(Context context, Uri uri) {

    Cursor cursor = context.getContentResolver().query(uri, null, null, null, null);
    cursor.moveToFirst();
    String image_id = cursor.getString(0);
    image_id = image_id.substring(image_id.lastIndexOf(":") + 1);
    cursor.close();
    cursor = context.getContentResolver().query(android.provider.MediaStore.Images.Media.EXTERNAL_CONTENT_URI, null, MediaStore.Images.Media._ID + " = ? ", new String[]{image_id}, null);
    cursor.moveToFirst();
    String path = cursor.getString(cursor.getColumnIndex(MediaStore.Images.Media.DATA));
    cursor.close();
    upLoadImageOrLogo(path);
}

Solusi bagi mereka yang memiliki masalah setelah pindah ke KitKat:

"Ini akan mendapatkan path file dari MediaProvider, DownloadsProvider, dan ExternalStorageProvider, sambil kembali ke metode ContentProvider tidak resmi" https://stackoverflow.com/a/20559175/690777

Setelah mendapatkan gambar dari galeri, kirimkan URI dalam metode di bawah ini hanya untuk Android 4.4 (KitKat):

public String getPath(Uri contentUri) {// Will return "image:x*"

    String wholeID = DocumentsContract.getDocumentId(contentUri);

    // Split at colon, use second item in the array
    String id = wholeID.split(":")[1];

    String[] column = { MediaStore.Images.Media.DATA };

    // Where id is equal to
    String sel = MediaStore.Images.Media._ID + "=?";

    Cursor cursor = getContentResolver().query(
            MediaStore.Images.Media.EXTERNAL_CONTENT_URI, column, sel,
            new String[] { id }, null);

    String filePath = "";

    int columnIndex = cursor.getColumnIndex(column[0]);

    if (cursor.moveToFirst()) {
        filePath = cursor.getString(columnIndex);
    }

    cursor.close();
    return filePath;
}

Coba ini

Namun, jika Anda mendapatkan masalah untuk mendapatkan jalan yang sebenarnya, Anda dapat mencoba jawaban saya. Jawaban di atas tidak membantu saya.

Penjelasan : - Metode ini mendapatkan URI dan kemudian memeriksa tingkat API perangkat Android Anda setelah itu menurut tingkat API itu akan menghasilkan jalur Nyata. Kode untuk menghasilkan metode jalur nyata berbeda menurut tingkat API.

1. metode untuk mendapatkan jalur Nyata dari URI

   @SuppressLint("ObsoleteSdkInt")
   public String getPathFromURI(Uri uri){
       String realPath="";
   // SDK < API11
       if (Build.VERSION.SDK_INT < 11) {
           String[] proj = { MediaStore.Images.Media.DATA };
           @SuppressLint("Recycle") Cursor cursor = getContentResolver().query(uri, proj, null, null, null);
           int column_index = 0;
           String result="";
           if (cursor != null) {
               column_index = cursor.getColumnIndexOrThrow(MediaStore.Images.Media.DATA);
               realPath=cursor.getString(column_index);
           }
       }
       // SDK >= 11 && SDK < 19
       else if (Build.VERSION.SDK_INT < 19){
           String[] proj = { MediaStore.Images.Media.DATA };
           CursorLoader cursorLoader = new CursorLoader(this, uri, proj, null, null, null);
           Cursor cursor = cursorLoader.loadInBackground();
           if(cursor != null){
               int column_index = cursor.getColumnIndexOrThrow(MediaStore.Images.Media.DATA);
               cursor.moveToFirst();
               realPath = cursor.getString(column_index);
           }
       }
       // SDK > 19 (Android 4.4)
       else{
           String wholeID = DocumentsContract.getDocumentId(uri);
           // Split at colon, use second item in the array
           String id = wholeID.split(":")[1];
           String[] column = { MediaStore.Images.Media.DATA };
           // where id is equal to
           String sel = MediaStore.Images.Media._ID + "=?";
           Cursor cursor = getContentResolver().query(MediaStore.Images.Media.EXTERNAL_CONTENT_URI, column, sel, new String[]{ id }, null);
           int columnIndex = 0;
           if (cursor != null) {
               columnIndex = cursor.getColumnIndex(column[0]);
               if (cursor.moveToFirst()) {
                   realPath = cursor.getString(columnIndex);
               }
               cursor.close();
           }
       }
       return realPath;
    }

2. Gunakan metode ini seperti ini

   Log.e(TAG, "getRealPathFromURI: "+getPathFromURI(your_selected_uri) );

Keluaran:-

04-06 12: 39: 46.993 6138-6138 / com.app.qtm E / tag: getRealPathFromURI: /storage/emulated/0/Video/avengers_infinity_war_4k_8k-7680x4320.jpg

Saya sudah melakukan ini:

    Uri queryUri = MediaStore.Files.getContentUri("external");
    String columnData = MediaStore.Files.FileColumns.DATA;
    String columnSize = MediaStore.Files.FileColumns.SIZE;

    String[] projectionData = {MediaStore.Files.FileColumns.DATA};


    String name = null;
    String size = null;

    Cursor cursor = getContentResolver().query(contentURI, null, null, null, null);
    if ((cursor != null)&&(cursor.getCount()>0)) {
        int nameIndex = cursor.getColumnIndex(OpenableColumns.DISPLAY_NAME);
        int sizeIndex = cursor.getColumnIndex(OpenableColumns.SIZE);

        cursor.moveToFirst();

        name = cursor.getString(nameIndex);
        size = cursor.getString(sizeIndex);

        cursor.close();
    }

    if ((name!=null)&&(size!=null)){
        String selectionNS = columnData + " LIKE '%" + name + "' AND " +columnSize + "='" + size +"'";

        Cursor cursorLike = getContentResolver().query(queryUri, projectionData, selectionNS, null, null);

        if ((cursorLike != null)&&(cursorLike.getCount()>0)) {
            cursorLike.moveToFirst();
            int indexData = cursorLike.getColumnIndex(columnData);
            if (cursorLike.getString(indexData) != null) {
                result = cursorLike.getString(indexData);
            }
            cursorLike.close();
        }
    }

    return result;

Karena managedQuery sudah tidak digunakan lagi, Anda dapat mencoba:

CursorLoader cursorLoader = new CursorLoader(context, uri, proj, null, null, null);
Cursor cursor = cursorLoader.loadInBackground();

Di sini saya akan menunjukkan kepada Anda bahwa cara membuat tombol BROWSE, yang ketika Anda mengklik, itu akan membuka kartu SD, Anda akan memilih File dan sebagai hasilnya Anda akan mendapatkan nama file dan path file yang dipilih satu:

Sebuah tombol yang akan Anda tekan

browse.setOnClickListener(new OnClickListener()
{
    public void onClick(View v)
    {
        Intent intent = new Intent();
        intent.setAction(Intent.ACTION_PICK);
        Uri startDir = Uri.fromFile(new File("/sdcard"));
        startActivityForResult(intent, PICK_REQUEST_CODE);
    }
});

Fungsi yang akan mendapatkan Nama File yang Dihasilkan dan Path File

protected void onActivityResult(int requestCode, int resultCode, Intent intent)
{
    if (requestCode == PICK_REQUEST_CODE)
    {
        if (resultCode == RESULT_OK)
        {
            Uri uri = intent.getData();

            if (uri.getScheme().toString().compareTo("content")==0)
            {
                Cursor cursor =getContentResolver().query(uri, null, null, null, null);
                if (cursor.moveToFirst())
                {
                    int column_index = cursor.getColumnIndexOrThrow(MediaStore.Images.Media.DATA);//Instead of "MediaStore.Images.Media.DATA" can be used "_data"
                    Uri filePathUri = Uri.parse(cursor.getString(column_index));
                    String file_name = filePathUri.getLastPathSegment().toString();
                    String file_path=filePathUri.getPath();
                    Toast.makeText(this,"File Name & PATH are:"+file_name+"\n"+file_path, Toast.LENGTH_LONG).show();
                }
            }
        }
    }
}

Apa pun cara untuk Android Q yang lalu , ketika MediaStore.Images.Media.DATA tidak akan tersedia lagi? Bidang ini disusutkan di Android Q:

Konstanta ini sudah tidak digunakan lagi di API level 29. Aplikasi mungkin tidak memiliki izin sistem file untuk langsung mengakses jalur ini. Alih-alih mencoba membuka jalur ini secara langsung, aplikasi harus menggunakan ContentResolver # openFileDescriptor (Uri, String) untuk mendapatkan akses.

https://developer.android.com/reference/android/provider/MediaStore.MediaColumns.html#DATA

--- Diedit

Sejauh yang saya tahu untuk Android Q masa lalu, satu-satunya cara adalah menyampaikan pada RELATIVE_PATH

Jalur relatif item media ini di dalam perangkat penyimpanan tempat item itu bertahan. Misalnya, item yang disimpan di /storage/0000-0000/DCIM/Vacation/IMG1024.JPG akan memiliki jalur DCIM / Liburan /.

https://developer.android.com/reference/android/provider/MediaStore.MediaColumns.html#RELATIVE_PATH

Versi @PercyPercy yang sedikit dimodifikasi - tidak melempar dan hanya mengembalikan nol jika terjadi kesalahan :

public String getPathFromMediaUri(Context context, Uri uri) {
    String result = null;

    String[] projection = { MediaStore.Images.Media.DATA };
    Cursor cursor = context.getContentResolver().query(uri, projection, null, null, null);
    int col = cursor.getColumnIndex(MediaStore.Images.Media.DATA);
    if (col >= 0 && cursor.moveToFirst())
        result = cursor.getString(col);
    cursor.close();

    return result;
}

Di sini Anda mendapatkan nama file

String[] projection = {MediaStore.MediaColumns.DISPLAY_NAME};
                    Uri uri = data.getData();
                    String fileName = null;
                    ContentResolver cr = getActivity().getApplicationContext().getContentResolver();

                    Cursor metaCursor = cr.query(uri,
                            projection, null, null, null);
                    if (metaCursor != null) {
                        try {
                            if (metaCursor.moveToFirst()) {
                                fileName = metaCursor.getString(0);
                            }
                        } finally {
                            metaCursor.close();
                        }
                    }

Sederhana dan mudah. Anda dapat melakukan ini dari URI seperti di bawah ini!

public void getContents(Uri uri)
{
    Cursor vidCursor = getActivity.getContentResolver().query(uri, null, null,
                                                              null, null);
    if (vidCursor.moveToFirst())
    {
        int column_index =
        vidCursor .getColumnIndexOrThrow(MediaStore.Images.Media.DATA);
        Uri filePathUri = Uri.parse(vidCursor .getString(column_index));
        String video_name =  filePathUri.getLastPathSegment().toString();
        String file_path=filePathUri.getPath();
        Log.i("TAG", video_name + "\b" file_path);
    }
}

Solusi ini berfungsi untuk setiap kasus:

Terlalu sulit dalam beberapa kasus mendapatkan jalur dari URL. Lalu mengapa Anda membutuhkan jalan? Untuk menyalin file di tempat lain? Anda tidak perlu jalan.

public void SavePhotoUri (Uri imageuri, String Filename){

    File FilePath = context.getDir(Environment.DIRECTORY_PICTURES,Context.MODE_PRIVATE);
    try {
        Bitmap selectedImage = MediaStore.Images.Media.getBitmap(context.getContentResolver(), imageuri);
        String destinationImagePath = FilePath + "/" + Filename;
        FileOutputStream destination = new FileOutputStream(destinationImagePath);
        selectedImage.compress(Bitmap.CompressFormat.JPEG, 100, destination);
        destination.close();
    }
    catch (Exception e) {
        Log.e("error", e.toString());
    }
}

Bekerja dengan sempurna untuk saya memperbaiki kode dari pos ini :

  public static String getRealPathImageFromUri(Uri uri) {
        String fileName =null;
        if (uri.getScheme().equals("content")) {
            try (Cursor cursor = MyApplication.getInstance().getContentResolver().query(uri, null, null, null, null)) {
                if (cursor.moveToFirst()) {
                    fileName = cursor.getString(cursor.getColumnIndexOrThrow(ediaStore.Images.Media.DATA));
                }
            } catch (IllegalArgumentException e) {
                Log.e(mTag, "Get path failed", e);
            }
        }
        return fileName;
    }

Sebagai tambahan, jika Anda perlu melihat apakah ada file sebelum Anda mencoba membuka aliran input, Anda dapat menggunakan DocumentsContract.

(Kode Kotlin)

var iStream = null
if(DocumentsContract.isDocumentUri(context,myUri)) {
   val pfd: ParcelFileDescriptor? = context.contentResolver.openFileDescriptor(
            myUri, "r") ?: return null
   iStream = ParcelFileDescriptor.AutoCloseInputStream(pfd)
}

Karena jawaban di atas tidak bekerja untuk saya, berikut adalah solusi yang bekerja untuk saya:

Untuk keduanya> 19 dan <= 19 Level API.
