Maximizing an AlertDialog?

Question

I'd like to show a Dialog that occupies as much screen space as possible.

So, here's a sample:

AlertDialog dialog = new AlertDialog.Builder(ctx)......create();
Window w = dialog.getWindow();
WindowManager.LayoutParams lp = w.getAttributes();
lp.width = 320;
lp.height = 480;
w.setAttributes(lp);

Problem is, this doesn't change a thing. Why?

TIA.

Answer 1

I don't know how to do exactly what you're wanting, but isn't this mostly defeating the purpose of a Dialog? Why not just create a custom Activity and use the Dialog theme if you're just wanting it to look dialog-ey.

Answer 2

You need to change the window layout parameters AFTER setContentView. Anything you do to the window before then (size/location-wise) will be tossed out when you call setContentView.
