The debug info is now gone, but the 19 container remains because there is a high likelihood of UI regression relating 20 to focus and selection states, some of which are specific to keyboard 21 when touch mode is not enable. So, if you, heroic engineer of the future, 22 decide to rip these out, please be sure to check out focus and keyboards. --> 23<LinearLayout 24 xmlns:android="http://schemas.android.com/apk/res/android" 25 android:layout_width="match_parent" 26 android:layout_height="wrap_content" 27 android:orientation="vertical" 28 android:layout_margin="4dp" 29 android:background="@drawable/grid_item_background" 30 android:elevation="@dimen/grid_item_elevation" 31 android:focusable="true"> 32 33 <RelativeLayout 34 android:layout_width="match_parent" 35 android:layout_height="wrap_content" 36 android:duplicateParentState="true"> 37 38 <!-- Main item thumbnail.
