Question

I want to create a dialog which appears when user presses a button. (In fact it’s kind of a volume control appearing when user clicks the button with headphones)

I have a layout file for dialog (with height dependent on content)
and in onCreate method I try to set gravity top|right and custom margin (the same as my button has).

this.getWindow().setGravity(Gravity.TOP | Gravity.RIGHT);
WindowManager.LayoutParams lp = this.getWindow().getAttributes();
lp.x = x;
lp.y = y;

But what I get is just a centered dialog on the right (not top-right!) without any margin.

In other words I’d like to draw my dialog with custom layout at specified point on the screen.

Answer 1

The easiest way to achieve this is by using a Relative Layout

RelativeLayout.LayoutParams params = new RelativeLayout.LayoutParams(WIDTH, HEIGHT);
params.topMargin = X;
params.leftMargin = Y;
yourRelativeLayout.addView(myDialog, params);

The X should be something like clickedX – WIDTH/2…

Hope this was helpfull!
