I'm trying to make a gallery application which only shows images from screenshot folder in my internal storage.
I found a solution from here but I'm having difficulties on how to specify the path to my desired folder.
This is the snippet:
cursor imagecursor = getContentResolver().query( MediaStore.Images.Media.EXTERNAL_CONTENT_URI,
columns,
MediaStore.Images.Media.DATA + " like ? ",
new String[] {"%/yourfoldername/%"},
null);
Can someone explain me what should I put in this " like ? "
and how can I specify my folder name in this new String[] {"%/yourfoldername/%"},
This is my code.
String[] projection = { MediaStore.MediaColumns.DATA,
MediaStore.Images.Media.BUCKET_DISPLAY_NAME, MediaStore.MediaColumns.DATE_MODIFIED };
Cursor cursor = getContentResolver().query( MediaStore.Images.Media.EXTERNAL_CONTENT_URI,
projection,
MediaStore.Images.Media.DATA + " like ? ",
new String[] {"%/sdcard/DCIM/Screenshots"},
null);
Any corrections will be highly appreciated. Cheers!
try with this
public static 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);
assert cursor != null;
int column_index = cursor.getColumnIndexOrThrow(MediaStore.Images.Media.DATA);
cursor.moveToFirst();
return cursor.getString(column_index);
} finally {
if (cursor != null) {
cursor.close();
}
}
}
