java - android:layout_alignParentBottom="true" and android:gravity="bottom" seem to have no affect on RelativeLayout -

I have a visible page that I'm trying to set in the lower part of the screen (lastly all other items With RELATIVE layout) However, Android: Layout_LinePantBotm = "True" and Android: Gravity = "below" has no effect on the resiliency layout and I'm not sure why

layout_alignParentBottom with layout_alignParentBottom : trying to use Android This issue> and other related attributes which provide RelativeLayout, are used to display those situations which are children of a relative layout, they can not be a RelativeLayout situation within their origin unless the RelativeLayout is a RelativeLayout inside Is nested

Rroid :. Gravity What you want, because it is used does not work. If you want to set a view in the lower part of your parent to present the children of the view within that view, then You should use android: layout_gravity . See for more information.

You may also want to read the documentation because I do not think it expects a lot for you. If you have only one drawer, then you should include DrawerLayout for only two drawers and main material children- (either of which the child could have been seen, but there is only two direct needs To be children).
