How to size an Android view based on its parent’s dimensions

how do I use getMeasuredWidth() and getMeasuredHeight? It always returns 0. what is the diffrence between this and getHeight() and getWidth()?

Just got a solution to get height and width of a custom view:

@Override
protected void onSizeChanged(int xNew, int yNew, int xOld, int yOld){
    super.onSizeChanged(xNew, yNew, xOld, yOld);

    viewWidth = xNew;
    viewHeight = yNew;
}

Its working in my case.

Don't try to get them inside its constructor. Try Call them in onDraw() method.

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

Well getheight gets the height, and getwidth gets the width. But you're calling those methods too soon. If you're calling them in oncreate or onresume, the view isn't drawn yet. You have to call it after the view has been drawn.

I was also lost around getMeasuredWidth() and getMeasuredHeight() getHeight() and getWidth() for a long time.......... later i found onSizeChanged() method to be REALLY helpful.

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.
