Question

I’m adding a custom View to the parent layout, witch is a RelativeLayout.

I also need to move this View on the screen so I do:

myView.layout(xx, yy, width, height);

This works. The view is moved each time I call this.

The Problem is that when this view is moved,
a copy of it keeps hanging on the top left corner of the layout,
like this:

Why this happens and how can I prevent this?

Thank you

— Edit —

Some code below.

In the constructor of my custom View:

LayoutInflater inflater = (LayoutInflater) context.getSystemService(Context.LAYOUT_INFLATER_SERVICE); 
inflater.inflate(R.layout.ipmaps_lib_balloon_overlay, this);

I then add this View to its parent:

final RelativeLayout.LayoutParams params = new RelativeLayout.LayoutParams(LayoutParams.WRAP_CONTENT, LayoutParams.WRAP_CONTENT);
parentLayout.addView(myView, params);  

When I need to move the View I just do:

myView.layout(startX, startY, width, height);
myView.invalidate  

Answer 1

I found the reason for this strange behaviour.
It was my fault.

Whenever I changed the position of this message balloon,
I was as well calling view.draw(canvas),
and for this reason, the view was being drawn twice.

Thank you all very much.
