Get height and width of a layout programmatically

Question

I have designed an layout in which LinearLayout has 2 children LinearLayout and FrameLayout and in each child I put different views.

Answer 1

Most easiest way is to use ViewTreeObserver, if you directly use .height or .width you get values as 0, due to views are not have size until they draw on our screen. Following example will show how to use ViewTreeObserver

ViewTreeObserver viewTreeObserver = YOUR_VIEW_TO_MEASURE.getViewTreeObserver();
        if (viewTreeObserver.isAlive()) {
            viewTreeObserver.addOnGlobalLayoutListener(new ViewTreeObserver.OnGlobalLayoutListener() {
                @Override
                public void onGlobalLayout() {

                    YOUR_VIEW_TO_MEASURE.getViewTreeObserver().removeOnGlobalLayoutListener(this);
                    int viewHeight = YOUR_VIEW_TO_MEASURE.getHeight();
                    int viewWeight = YOUR_VIEW_TO_MEASURE.getWidth();

                }
            });
        }

if you need to use this on method, use like this and to save the values you can use globle variables.
