You'd really benefit from using xml in the future :) – Warpzit Mar 09 '13 at 06:18 — Warpzit, Mar 09 '13 at 06:18

The code that you are complaining about isn't adding the ImageView - mTouchDetector - to your layout. You must add it in order for it to be visible if you are using plain Java instead of XML. Look at your first example (the working one):

mWindowManager.addView(mTouchDetector, mParams);

That's the idea here.

ImageView isn't visible and motion event isn't works well
