You can directly create Bitmaps from decodeFile (String pathName) that will give you Bitmap object that can be set on ImageView.

File path = new File(Environment.getExternalStorageDirectory(),"iWallet/Images");
if(path.exists())
{
    String[] fileNames = path.list();
}
for(int i = 0; i < filename.length; i++)
{
     Bitmap mBitmap = Bitmap.decodeFile(path.getPath()+"/"+ fileNames[i]);
     ///Now set this bitmap on imageview
}

Pass directory name as selectionArgs and change selection String as:

 String selection = MediaStore.Images.Media.DATA + " like ? ";
 String selectionArgs =new String[] {"%PASS_DIR_NAME_HERE%"};

 new CursorLoader(getContext(),MediaStore.Files.getContentUri("external"), 
                 projection, 
                 selection, 
                 selectionArgs,
                 MediaStore.Files.FileColumns.DATE_ADDED + " ASC");
