问题 In my layout (its layout for custom dialog class), whenever I set my layout attributes like this : android:layout_width="match_parent" android:layout_height="match_parent" I don't see a layout that spreads all over the screen, I see it like this: As you can see, the dialog is very small and weird looking although I am using match_parent , the weird part is that whenever I use fixed size I see it normally.
