Under android:scaleType="matrix" circumstance, the only way I found is to use Matrix to set ImageView position, use the following code:

Matrix matrix = new Matrix();
matrix.postTranslate(screen_width/2, screen_height/2);
imageView.setImageMatrix(matrix);

I had the sameproblem. Eventually I Gave up for using Matrix and replaced it with this:

android.view.ViewGroup.LayoutParams params = imageView.getLayoutParams();
params.height = desiredHeight;
params.width = desiredWid;
imageView.setLayoutParams(params);

this may help you

This will work for sure, but then `ImageView` sets its boundary and so It wont allow user to zoom Image outside of its boundary. — Jeeten Parmar, May 20 '14 at 09:00
