If you need to set your width or height to match parent  as big as its parent  or wrap content  large enough to fit its own internal content   then ViewGroup LayoutParams has this two constants   imageView setLayoutParams      new ViewGroup LayoutParams             or ViewGroup LayoutParams WRAP CONTENT         ViewGroup LayoutParams MATCH PARENT                   or ViewGroup LayoutParams WRAP CONTENT               ViewGroup LayoutParams MATCH PARENT        Or you can set them like in Hakem Zaied s answer   imageView getLayoutParams   width   ViewGroup LayoutParams MATCH PARENT
