You can use the following method to get the width and height of the view  For example   int height   yourView getLayoutParams   height  int width   yourView getLayoutParams   width    This gives the converted value of the view which specified in the XML layout    Say if the specified value for height is 53dp in XML  you will get the converted value in integer as 80

The difference between getHeight   and getMeasuredHeight   is that first method will return actual height of the View  the second one will return summary height of View s children  In ohter words  getHeight   returns view height  getMeasuredHeight   returns height which this view needs to show all it s elements
