Question 1

For example, suppose that in a XML file (res/menu/menu_main.xml as an example), where menu items are described, we have such item:

...

android:id="@+id/action_settings"

android:orderInCategory="100"

android:title="@string/menu_action_settings"

app:showAsAction="never" />

...

Attribute ''app:showAsAction'' shows when and how this item should appear as an action item in the app bar. What value ''never'' in this attribute means?

AOnly place this item in the app bar if there is room for it. If there is not room for all the items marked by this value, the items with the lowest orderInCategory values are displayed as actions, and the remaining items are displayed in the overflow menu.

BAlso include the title text (defined by android:title) with the action item. You can include this value along with one of the others as a flag set, by separating them with a pipe.

CNever place this item in the app bar. Instead, list the item in the app bar's overflow menu.

DAlways place this item in the app bar. Avoid using this unless it's critical that the item always appear in the action bar. Setting multiple items to always appear as action items can result in them overlapping with other UI in the app bar.

EThe action view associated with this action item (as declared by android:actionLayout or android:actionViewClass) is collapsible.

A content label sometimes depends on information only available at runtime, or the meaning of a View might change over time. For example, a Play button might change to a Pause button during music playback. In these cases, to update the content label at the appropriate time, we can use:

AView#setContentDescription(int contentDescriptionResId)

BView#setContentLabel(int contentDescriptionResId)

CView#setContentDescription(CharSequence contentDescription)

DView#setContentLabel(CharSequence contentDescription)
