Set ImageView width and height programmatically?

Question

How can I set an ImageView's width and height programmatically?

Answer 1

It may be too late but for the sake of others who have the same problem, to set the height of the ImageView:

imageView.getLayoutParams().height = 20; 

Important. If you're setting the height after the layout has already been 'laid out', make sure you also call:

imageView.requestLayout(); 

Answer 2

If your image view is dynamic, the answer containing getLayout will fail with null-exception.

In that case the correct way is:

LinearLayout.LayoutParams layoutParams = new LinearLayout.LayoutParams(100, 100); iv.setLayoutParams(layoutParams);
