Fragment Gets No Width And No Height

The Dialog that you see is a activity with a Dialog theme. The layout inside it is a fragment that should match its width and height. It is added programatically using the FragmentTransaction class.

The issue is that the fragment layout gets squished together and looks awful. I have used match_parent in the xml on both the fragments layout and activitys.

How do i stop the dialog from being squished together and have a more "natural" size?

Customizing the height and width of alert dialog android. Following is the code

WindowManager.LayoutParams params = new WindowManager.LayoutParams();

params.copyFrom(alertDialog.getWindow().getAttributes());
params.width = 100;
params.height = 400;
params.x=-190;
params.y=80;
alertDialog.getWindow().setAttributes(params);

Not sure but hope it will work.
