Display MediaRouteButton for Chromecast in the action bar

Question

Netflix and YouTube apps that support Chromecast display MediaRouteButton in the action bar, but the sender app shows how to display it in the layout. How do you display it in the action bar?

Answer 1

You can display it in the action bar by adding it to the action bar menu:

<item android:id="@+id/action_mediaroute" android:actionProviderClass="android.support.v7.app.MediaRouteActionProvider" android:actionViewClass="android.support.v7.app.MediaRouteButton" android:showAsAction="always" android:title="@string/action_chromecast"/> 

Then you provide initialization in onCreateOptionsMenu :

 public boolean onCreateOptionsMenu( Menu menu ) { getMenuInflater().inflate( R.menu.main, menu ); MenuItem mediaRouteItem = menu.findItem( R.id.action_mediaroute ); mMediaRouteButton = (MediaRouteButton) mediaRouteItem.getActionView(); mCastContext = new CastContext( getApplicationContext() ); MediaRouteHelper.registerMinimalMediaRouteProvider( mCastContext, this ); mMediaRouter = MediaRouter.getInstance( getApplicationContext() ); mMediaRouteSelector = MediaRouteHelper.buildMediaRouteSelector( MediaRouteHelper.CATEGORY_CAST ); mMediaRouteButton.setRouteSelector( mMediaRouteSelector ); mMediaRouterCallback = new MyMediaRouterCallback(); return true; }
