Insert an Image from the gallery on a button in Android

Question

Im trying to do this:

protected void onActivityResult(int requestCode, int resultCode, Intent data) {
    super.onActivityResult(requestCode, resultCode, data);

    if (requestCode == 1 && resultCode == RESULT_OK && null != data) {
        Uri selectedImage = data.getData();
        String[] filePathColumn = { MediaStore.Images.Media.DATA };

        Cursor cursor = getContentResolver().query(selectedImage,
                filePathColumn, null, null, null);
        cursor.moveToFirst();

        int columnIndex = cursor.getColumnIndex(filePathColumn[0]);
        String picturePath = cursor.getString(columnIndex);
        cursor.close();
        Bitmap bmp = BitmapFactory.decodeFile(picturePath);
        b[1].setCompoundDrawablesWithIntrinsicBounds(null, new BitmapDrawable(bmp), null, null);
}

But it wont set the image, no matter what. I have tried several different methods too, like using an imagebutton instead of a button and using:

imageButton.setImageBitmap(bmp)

The gallery opens fine and and the callback comes to onActivityResult(...) but the image wont appear on the button, I have an array of buttons.

I made a rapid test. The following code works for me. If with this you still can't set the image I would check if there's a layout problem (i.e. the image is set but there's no room to show it).

activity_main.xml has just an ImageButton set to wrap_content, inside the main layout which is match_parent.

public class MainActivity extends Activity {

    ImageButton imgButton;

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        imgButton = (ImageButton) findViewById(R.id.imgButton);

        imgButton.setOnClickListener(new OnClickListener() {
            @Override
            public void onClick(View v) {
                Intent intent = new Intent(Intent.ACTION_PICK);
                intent.setType("image/*");

                startActivityForResult(intent, 0);
            }
        });
    }

    @Override
    protected void onActivityResult(int requestCode, int resultCode, Intent data) {
        super.onActivityResult(requestCode, resultCode, data);

        if(requestCode == RESULT_CANCELED) return;

        ParcelFileDescriptor fd;
        try {
            fd = getContentResolver().openFileDescriptor(data.getData(), "r");
        } catch (FileNotFoundException e) {
            e.printStackTrace();
            return;
        }

        Bitmap bmp = BitmapFactory.decodeFileDescriptor(fd.getFileDescriptor());

        imgButton.setImageBitmap(bmp);
    }   
}
