The highlighted RelativeLayout (@+id/previewLayout)

should only go to the top of this RelativeLayout (@+id/messageLayout):

But it goes all the way to the bottom of the screen/parent. What did I do wrong?

Answer 1

Put this line in your @+id/previewlayout Relative layout node..

 android:layout_above="@+id/messageLayout"
