Android getMeasuredHeight returns wrong values !

Question

I\'m trying to determine the real dimension in pixels of some UI elements !

Those elements are inflated from a .xml file and are initialized with dip width and height

Answer 1

Ok ! Kind of Answering my own question here...But not completly

1 - It seems that on some devices, The ImageView measuring do not provide with exact values. I've seen lots of reports on this happenning on Nexus and Galaxy devices for example.

2 - A work around that I've come up with :

Set the width and height of your ImageView to "wrap_content" inside xml code.

Inflate the layout inside your code (generally in the UI initialization I suppose).

LayoutInflater inflater     = (LayoutInflater) 
_parent.getContext().getSystemService(Context.LAYOUT_INFLATER_SERVICE);
ViewGroup root      = (ViewGroup) inflater.inflate(R.layout.tl_frame, null);
ImageView frame = (ImageView) root.findViewById(R.id.TlFrame);

Calculate your own ratio for your image view, based on the typical Android calculation

//ScreenDpi can be acquired by getWindowManager().getDefaultDisplay().getMetrics(metrics);
 pixelWidth = wantedDipSize * (ScreenDpi / 160)

Use the calculated size to set your ImageView dynamycally inside your code

frame.getLayoutParams().width = pixeWidth;

And voila ! your ImageView has now the wanted Dip size ;)
