How to get the width and height of an android.widget.ImageView?
My answer on this question might help you:
int finalHeight, finalWidth;final ImageView iv = (ImageView)findViewById(R.id.scaled_image);final TextView tv = (TextView)findViewById(R.id.size_label);ViewTreeObserver vto = iv.getViewTreeObserver();vto.addOnPreDrawListener(new ViewTreeObserver.OnPreDrawListener() { public boolean onPreDraw() { iv.getViewTreeObserver().removeOnPreDrawListener(this); finalHeight = iv.getMeasuredHeight(); finalWidth = iv.getMeasuredWidth(); tv.setText("Height: " + finalHeight + " Width: " + finalWidth); return true; }});You can then add your image scaling work from within the onPreDraw() method.
