layout_height property is set RelativeLayout layout of Android is wrap_content pit:
This condition occurs in the pit:
layout_height property is set 1.RelativeLayout layout is wrap_content
2. a "Center View" is set to layout_centerX (layout_centerVertical, layout_centerHorizontal, layout_centerInParent)
3. Other View with respect to the "Center View" to do the layout
At this pit appeared:
View other matter provided below (layout_below, layout_below) "centered View", above (layout_above), align the bottom (layout_alignBottom) and so on, all invalid!
Filled pit program:
layout_height property RelativeLayout layout can be set to match_parent!
Even if the outer space has equally LinearLayout layout_weight use, it match_parent not stretch outer LinearLayout space.
Originally want to set wrap_content, in fact, is the fear of internal RelativeLayout set after match_parent is stretch it, proved too much concern!
