Android modify ImageView parameters after adding to Layout

If I have a ImageView foo I can modify its parameters before adding it to a Layout with:

 RelativeLayout.LayoutParams testParams = new RelativeLayout.LayoutParams(500,500);
foo.setLayoutParams(testParams);

then I add foo to the layout with:

exampleLayout.addView(foo);

How can I modify the parameters after adding foo to the layout? (I read that there was a different process if foo was already added to the layout)

Try to modify layout parameters before adding to its parent, but if you want to modify it, first find it by its ID, then use getLayoutParams() method and modify it, then set it again using setLayoutParams().

You can still edit after adding the foo. on your foo add the id at runtime. Lets say. foo.setId(23); now at runtime examplelayout.findviewbyid(23) will give you your view. Now you can update params on that. and call invalidate()
