The other answers demonstrate how to get the dimensions, but you are trying to do it too early, before the layout has been measured. This is how you do this but I am pretty sure you should never need to do this - there is almost always a better way that does not require you to know the pixel dimensions of anything.
myimgbg.getViewTreeObserver().addOnGlobalLayoutListener(new ViewTreeObserver.OnGlobalLayoutListener() { @Override public void onGlobalLayout() { myimgbg.getViewTreeObserver().removeGlobalOnLayoutListener(this); int width = myimgbg.getWidth(); } }); Just to emphasize again, if you are doing something that requires knowing the exact pixel size of a view, you should probably take a step back and reconsider how to do what you want.

thanks!!.. I want to get the value with
int width; myimgbg.getViewTreeObserver().addOnGlobalLayoutListener(new ViewTreeObserver.OnGlobalLayoutListener() { @Override public void onGlobalLayout() { myimgbg.getViewTreeObserver().removeGlobalOnLayoutListener(this); width = myimgbg.getWidth(); } }); Log.e("with",with+"");

The problem is the width is just not available when you run this code. You have to wait for the callback after the measurement has occurred. Put any code that depends on width (i.e., your log statement) inside the onGlobalLayout()
Check this :
image_view.getLayoutParams().height image_view.getLayoutParams().width Hope this helps.

try myimgbg.getWidth() and myimgbg.getHeight()
This is simple way to get width and height from imageview
ImageView img = (ImageView) findViewById(R.id.img); Log.d(TAG, "width : " + img.getWidth());

Just try, after your view is drawn
yourView.getHeight() yourView.getWidth() or
LayoutParams params=yourView.getLayoutParams(); params.height //is your views height

I do, but returns 0..why?..help
Try this:
int width=image.getWidth(); int Height=image.getHeight();
