Set SlidingDraw components and icon buttons ImageButton problem

upload layout

Were said to be the problem 1.This SlidingDrawer layout or its LinearLayout parent is possibly useless
2. [Accessibility] Missing contentDescription attribute on image
3.No orientation specified, and the default is horizontal. This is a common source of bugs when
children are added dynamically.
