onDraw() on View draws behind the layout

Question

Ok, here's the deal. I want to move items in my extended gallery class to change the order of images. The way i'm doing it now:

• on long press remove the current selected item,
• use onDraw() to draw the same image so i can move it around using onTouchEvent()
• on release add the item again

This works fine but the problem is that when using the onDraw() method it will draw the image behind the gallery items. Is there a way to change the priority of what is drawn?

Answer 1

Well i found this out after going into a totally different direction =/

Here's the solution for people that have the same problem:

In constructor (or anywhere else you initialize the component) set setWillNotDraw(false) and override dispatchDraw(). dispatchDraw() draws the ViewGroup children so you can decide yourself if you want to draw behind or a top of the other views.

Example taken from Custom drawing on top of Gallery view (and it's child views)

@Override
protected void dispatchDraw(Canvas canvas) {
    super.dispatchDraw(canvas);

    // do your drawing stuff here
    canvas.drawPath(mPath,mPaint);
}
