Layout

• RelativeLayout
• LinearLayout

Notes:

1. If there is no following line, the message and buttons will overlap with the application title.

   app:layout_behavior=”@string/appbar_scrolling_view_behavior”

2. The default weight for all views is 0, so if you specify any weight value greater than 0 to only one view, then that view fills whatever space remains after all views are given the space they require.

   <EditText
       android:id="@+id/edit_message"
       android:layout_height="wrap_content"
       android:layout_weight="1"
       android:layout_width="0dp"
       android:hint="@string/edit_message"
   />
