How to get the Height and Width of the View?

Question

I need to get the height and width of the View before adding into layout or its is display. I have tried with using MeasuredHeight and MeasuredWidth of the view but its retursn as 0. Could you please help me out to resolve this?

Below code snippet I have tried out:

 int height = Column.MeasuredHeight;
 int width  = Column.MeasuredWidth;

@tompadre Thanks for the update. Column.Measure(View.MeasureSpec.MakeMeasureSpec(0, MeasureSpecMode.Unspecified), View.MeasureSpec.MakeMeasureSpec(0, MeasureSpecMode.Unspecified)); int colHeight = Column.MeasuredHeight; By using this solution, i am not getting actual height of the column. — Parthiban, May 03 '17 at 08:54
then try the answer above. http://stackoverflow.com/a/16437972/5577679 Proper way to get dimensions before inflating view is by ViewTreeObserver which is explained in the answer above. Official documentation is here https://developer.android.com/reference/android/view/ViewTreeObserver.html — tompadre, May 03 '17 at 09:19

You need to use a Layout change event to not receive 0 as the height. If you ask it too soon, the layout isn't drawn yet. Use the ViewTreeObserver of the layout that you want to measure.

LinearLayout linearLayout = FindViewById<LinearLayout>(Resource.Id.linearLayout);
ViewTreeObserver vto = linearLayout.ViewTreeObserver;

vto.GlobalLayout += (sender, args) => {
    System.Console.WriteLine (linearLayout.Height);
};

Thanks for the update. But this event calls after which i set the column height. I need to to call this event before that. – Parthiban May 03 '17 at 14:06
@Parthiban Can't you just put the set column height into the vto.GlobalLayout? – Dennis Reep May 03 '17 at 14:25
i can able to set. But this Global Layout event trigger after my method called. – Parthiban May 03 '17 at 14:34
I meant like this: vto.GlobalLayout += (sender, args) => { //Set the height here. }; – Dennis Reep May 03 '17 at 15:12

View view= LayoutInflater.from(this).inflate(R.layout.activity_main, null, false);
setContentView(view);
int viewWidth = view.getWidth();
int viewHeight = view.getHeight();
