Answer 1

UPDATE:

Do this:

int height=imageView.getHeight();
int width=imageView.getWidth();
imageView.setLayoutParams(new LinearLayout.LayoutParams(height, width));

Suggesting your ImageView is located inside a LinearLayout you need to do this:

LinearLayout.LayoutParams params = (LinearLayout.LayoutParams) imageView.getLayoutParams();
params.setHeight(XX);
params.setWidth(XX);
imageView.setLayoutParams(params);

I don't know if the syntax is perfectly correct, but basically this is how you do it, don't forget that you need to update your UI, in order to see any changes.

Answer 2

I use the following code for it:

your_image_view.getLayoutParams().height = 20;

Hope it helps u..

you can try the following alternate approach.. see if it works:

LayoutParams params = (LayoutParams) imageView.getLayoutParams();
params.width = 120;
params.height = 120;

imageView.setLayoutParams(params);

Although both the codes are almost same...
