Answer 1

You can try to use matrix.

set the scaleType of the ImageView to matrix.

<ImageView
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:scaleType="matrix" />

then translate the matrix used by the ImageView a little bit to the right every milliseconds.

Matrix matrix = new Matrix();
matrix.postTranslate(x, y);
img_animation.setImageMatrix(matrix);
