Apps How to set view position on parent?

[Zilon]

Hello to everybody.
Here is my problem:
In my android application I need to use custom menu. In xml I make menu layout (RelativLayout)
and inflate it on application start, then add it to parent layout, which was set by setContentView().
So I have something like this:

private void initMenu()
    {
    	LayoutInflater inflanter = getLayoutInflater(); 
    	menu = (RelativeLayout) inflanter.inflate(R.layout.menu, null, false);
    	
    	LayoutParams param = new LayoutParams(ViewGroup.LayoutParams.WRAP_CONTENT, 
   			ViewGroup.LayoutParams.WRAP_CONTENT);
    	
    	menuParent.addView(menu, param);   	
       	
    	hideMenuAnim = AnimationUtils.loadAnimation(this, R.anim.menu_hide);
    	showMenuAnim = AnimationUtils.loadAnimation(this, R.anim.menu_show);
    }

But I can't to set position for menu layout (using menu.layout(l, t, r, b).
menu.layout() don't do anything during initialization. I try to call layout() in
protected void onStart(), protected void onResume(), public void onChildViewAdded(View parent, View child) methods.
I try to create my custom class "class MenuLayout extends RelativeLayout{ ..." and set position in onLayout method:

protected void onLayout(boolean changed, int l, int t, int r, int b) {
		Rect posRect = new Rect();
		callback.getPosition(posRect);
		super.onLayout(changed, posRect.left, posRect.top, posRect.right, posRect.bottom);
		}

But position of menu don't change.
menu.layout() begin to work later when, as I understand, parrent view is completely initialized because
next code works normally (position is changed):

public boolean onKeyDown (int keyCode, KeyEvent event)
	{
		if(KeyEvent.KEYCODE_DPAD_UP == keyCode)
		{
				menu.layout(menuPosRect.left, menuTopPos, menuPosRect.right, menuBottomPos);
		}
	...
	}

PS: layout_graviti and graviti works very funny.., as always ))
