android - Android: YouTube ビデオをフルスクリーンで見ているときに、戻るボタンを押すとアクティビティが終了します

Question

YouTubeビデオから全画面表示を終了する方法は、押し戻すActivityことです。

コードを投稿します：

public class MainActivity extends YouTubeFailureRecoveryActivity {
    public static String prefix = "https://gdata.youtube.com/feeds/api/playlists/";
    public static String sufix = "?v=2&alt=jsonc";

    private String myPlayList = "PLZGKlf2ZwY7ua0C2oeUaXQKeLKNGy3mkh";

    private VideosListFragment videosFragment;

    // The next video to play
    private Video actualVideo;

    // This is the handler that receives the response when the YouTube read
    private Handler responseHandler;


    /** Called when the activity is first created. */
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        videosFragment = (VideosListFragment) getFragmentManager().findFragmentById(R.id.videosListView);
        getUserYouTubeFeed();

    }

    @Override
    public void onInitializationSuccess(YouTubePlayer.Provider provider,
            YouTubePlayer player, boolean wasRestored) {
        if (!wasRestored) {
            player.loadVideo(actualVideo.getVideoId());
        }
    }

    @Override
    protected YouTubePlayer.Provider getYouTubePlayerProvider() {
        return (YouTubePlayerFragment) getFragmentManager().findFragmentById(
                R.id.youtube_fragment);
    }

    public void getUserYouTubeFeed() {
        responseHandler = new Handler() {
            public void handleMessage(Message msg) {
                populateListWithVideos(msg);
            };
        };
        // We start a new AsyncTask that does its work on its own thread
        // We pass in a handler that will be called when the task has finished
        LoadPlayListElements bgTask = new LoadPlayListElements(responseHandler);
        bgTask.execute(myPlayList);

    }

    /**
     * This method retrieves the Library of videos from the task and passes them
     * to our ListView
     * 
     * @param msg
     */
    private void populateListWithVideos(Message msg) {
        Library lib = (Library) msg.getData().get(
                LoadPlayListElements.LIBRARY);
        VideosAdapter videos = new VideosAdapter(this, lib.getVideos());
        videosFragment.setListAdapter(videos);
    }

    @Override
    protected void onStop() {
        // Make sure we null our handler when the activity has stopped
        responseHandler = null;
        super.onStop();
    }

    public void setVideo(Video _item, boolean _activate) {
        actualVideo = _item;
        if (_activate){
            YouTubePlayerFragment fragment = (YouTubePlayerFragment) getFragmentManager()
                    .findFragmentById(R.id.youtube_fragment);
            if (fragment != null && fragment.isInLayout()) {
                fragment.initialize(DeveloperKey.DEVELOPER_KEY, this);
            }
        }
    }
}

そしてレイアウト：

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="horizontal"
    android:paddingBottom="@dimen/activity_vertical_margin"
    android:paddingLeft="@dimen/activity_horizontal_margin"
    android:paddingRight="@dimen/activity_horizontal_margin"
    android:paddingTop="@dimen/activity_vertical_margin" >

    <fragment
        android:id="@+id/videosListView"
        android:layout_width="0dp"
        android:layout_height="match_parent"
        android:layout_weight="1"
        android:layout_marginTop="?android:attr/actionBarSize"
        class="com.vivoenmimundo.sc2hotsepicreplays.ui.phone.fragment.VideosListFragment" >
    </fragment>

    <fragment
      android:name="com.google.android.youtube.player.YouTubePlayerFragment"
      android:id="@+id/youtube_fragment"
      android:layout_width="0dp"
      android:layout_height="wrap_content"
      android:layout_weight="2"
      android:layout_gravity="center_vertical"/>
</LinearLayout>

何か案が？YouTube の API の例からコピーして貼り付けるだけです。

戻るボタンの押下を検出し、それが何をするかをカスタム定義することができます。

// Sets functionality of the hard buttons on the device
@Override 
public boolean onKeyUp(int keyCode, KeyEvent event)
{
    if (keyCode == KeyEvent.KEYCODE_BACK) {
        // Custom define what you want to happen
    }
    return true;
}
