get layout height and width at run time android

Question

How can I get width and height of a linear layout which is defined in xml as fill_parent both in height and width? I have tried onmeasure method but I dont know why it is no

Answer 1

The width and height values are set after the layout has been created, when elements have been placed they then get measured. On the first call to onSizeChanged the parms will be 0 so if you use that check for it.

Little more detail here https://groups.google.com/forum/?fromgroups=#!topic/android-developers/nNEp6xBnPiw

and here http://developer.android.com/reference/android/view/View.html#Layout

Here is how to use onLayout:

@Override
protected void onLayout(boolean changed, int l, int t, int r, int b) {
    int width = someView.getWidth();
    int height = someView.getHeight();
}
