Height and Width of a view are always 0 ( getMeasuredHeight() and getHeight() both are not working )

I have a LinearLayout inside a LinearLayout and child linearlayout have its layout params where height and width are defined as 

LinearLayout linearLayout=new LinearLayout(context);
        LinearLayout.LayoutParams lp=new LinearLayout.LayoutParams(50,50);
        linearLayout.setLayoutParams(lp);

now after view created i am trying to get height of a view from getHeight() and getMeasuredHeight() but both methods returning 0 . ?

  int heightofView=linearLayout.getHeight(); 
  int heightofview=linearLayout.getMeasuredHeight();

why both these methods are returning 0 height of a view ? when these methods return the actual result ? how to get height of my created view ?

Do as below -

linearLayout.post(new Runnable() {
            @Override
            public void run() {
                int linearLayoutHeight = linearLayout.getHeight();
                Log.e("MS", "linearLayout Ht = " + linearLayoutHeight);
            }
        });

Try this code.

imageView.getViewTreeObserver().addOnGlobalLayoutListener(new ViewTreeObserver.OnGlobalLayoutListener() {
      @Override
      public void onGlobalLayout() {
           int width = imageView.getWidth();
           int height = imageView.getHeight();
           //you can add your code here on what you want to do to the height and width you can pass it as parameter or make width and height a global variable
           imageView.getViewTreeObserver().removeOnGlobalLayoutListener(this);
      }
});
