Add checkbox to android action bar
I have a problem when I was adding a checkbox in the action bar, it doesn't show the checkbox in the action bar which only shows the title of the checkbox.
`
<item
android:id="@+id/action_settings"
android:orderInCategory="100"
android:showAsAction="never"
android:title="@string/action_settings"/>
<item
android:id="@+id/action_delete"
android:icon="@drawable/ic_action_discard"
android:showAsAction="always"
android:title=""/>
<item
android:id="@+id/check_all"
android:actionViewClass="android.widget.checkbox"
android:showAsAction="always"
android:title="@string/action_check"/>
<item
android:id="@+id/action_add"
android:icon="@drawable/ic_action_add"
android:showAsAction="always"
android:title="@string/action_add"/>
`this is my .XML menu

The accepted answer doesn't work for me. The tag Checkable
did the trick:
<item
android:id="@+id/check_all"
android:checkable="true"
android:showAsAction="always"
android:title="@string/action_check"/>
And then in the Activity that inflates it you should have something like this to reflect the change in the monitored state (otherwise it won't change the selected state even if you click it):
public boolean onOptionsItemSelected(MenuItem item) {
switch(item.getItemId()){
case R.id.check_all:
item.setChecked(!item.isChecked());
return true;
}
}
