Answer 1

Set new new LayoutParams(200, 200) everytime.

screenDensity = getResources().getDisplayMetrics().density;
dimInDP = 200 * (screenDensity/(float)160)
imageTextView.setLayoutParams(new LinearLayout.LayoutParams(dimInDP ,dimInDP ));

EDIT : The Android system takes 160dpi as the reference density for density independent pixel calculation. For example, in your case you need dimension as 200dp. The system takes this as the numbersof pixels you want on a device of screen density 160dpi. So at runtime it scales the width relative to the reference density.

Assume you run ur app on a screen density 120. The view width will be scaled to 150 physical pixels.
