Try img1.getLayoutParams().width and img1.getLayoutParams().height

If it's not working, try below 

img1.measure(MeasureSpec.UNSPECIFIED, MeasureSpec.UNSPECIFIED);
int width = img1.getMeasuredWidth();
int height = img1.getMeasuredHeight();

Looking at the API documentation, this method should be what you need. You force the view to measure itself in runtime so you know exactly what dimensions the view is at that moment, it maybe an entirely different size on a different size screen.

Then you just call getMeasuredWidth() or getMeasuredHeight()

Used in an example:

img1.measure(MeasureSpec.EXACTLY, MeasureSpec.EXACTLY);
int width = img1.getMeasuredWidth();
int height = img1.getMeasuredHeight();

A quick caveat, the measure() method is available in every version of Android however the getMeasuredWidth() and getMeasuredHeight() methods are only available in Android 4.1 and above.

Hope this helps
