Delete Photo Thumbnail In Gallery After Manually Delete The Photo File

case R.id.menu_delete: File photoToDelete = new File(photoPath, photoList[gPosition]); photoToDelete.delete(); checkPhotoFolder(); galleryAdapter.notifyDataSetChang

Solution 1:

Try invoke the MediaScanner to refresh the gallery

// Tell the media scanner about the new file so that it is// immediately available to the user.MediaScannerConnection.scanFile(this,
        newString[] { file.toString() }, null,
        newMediaScannerConnection.OnScanCompletedListener() {
    publicvoidonScanCompleted(String path, Uri uri) {
        Log.i("ExternalStorage", "Scanned " + path + ":");
        Log.i("ExternalStorage", "-> uri=" + uri);
    }
});

Code from Google's example

Solution 2:

Try this.

getContentResolver().delete(Uri.fromFile(photoToDelete), null, null);

Solution 3:

You must update the data structure (eg. list or array) that stores the photos. I guess it is photoList. So you should do (assuming photoList is an array):

photoList = photoList.asList().remove(gPosition).toArray();
