Resize dialog to take up more screen

I have a dialog that setContentView on a layout. I have an editText and Button in the layout set width to match parent but that makes it only as wide as the setTitle. As I enter info into the editText, the dialo开发者_高级运维g expands with each character. Is it possible to make the dialog look like below without setting a dp size for the width of the items? Some system standard?

In most cases, a dialog being too small indicates that you're using fill_parent instead of wrap_content (or match_parent).

You would think that fill_parent always ends up larger than wrap_content, but that's not the case with EditTexts.

Also, consider using android:minEms for your EditText.
