Android Dialog keeps fidgeting - won't remain one size

Question

I have a pop-up dialog that is prompted by a button. I recently added a few more categories to be displayed on the screen, and now the dialog is behaving strangely. After I click the prompt, the dialog pops up, but it doesn't remain still; instead, it repeatedly gets thinner then wider, and just moving quickly back and forth. Has anyone else encountered this? Here is the XML code for the pop-up:

Answer 1

try this

Window window = customDialog.getWindow();
window.setLayout(WindowManager.LayoutParams.MATCH_PARENT,WindowManager.LayoutParams.WRAP_CONTENT);
