Question

Probably simple but i cannot figure this out.

I have a subclass of SlidingDrawer only to handle the hight correctly.
(thanks to @seydhe for the solution)

The problem is that when i open the drawer the hight is not set correctly,
It get set as soon as i lift my finger from the handle-butten.
How can i make the SlidingDrawer set the hight before i start pulling the drawer?

I have tries in various combinations to slidingDrawerRight.requestLayout();
and it works. The problem is where can i call it?
I have tried in various places like
OnClickListener
OnTouchListener
OnDrawerCloseListener
but i cannot get it to work.
Maybe there’s a way to fix the xml to do this?

adding tree images and the xml.

As shown in down belove picture nr:1,
I start to open the drawer
and the size is irregular:

NR1: Image when being opened..

NR2: Image when fully opened as soon as i let go of finger.

nr3 Image when SD background is set to #eeffae and RelativLayout background is @null

Answer 1

answering my own question.
I set the background to transparent like this

android:background="@null" 

Looks ok and the odd resizing behavior still happens but it’s not visible.
