Android YouTube api v3 - 方向

Question

使用 YouTubeBaseActivity、YouTubePlayerView 和 YouTubePlayer 启动并运行示例 Activity 非常简单。我在定位方面遇到了问题，但找不到任何文档或示例代码。当我在播放视频时切换时，屏幕是空白的。

在 onCreate()、onPause()、onSaveInstanceState() 和 onRestoreInstanceState() 中，要让视频继续播放，正确的做法是什么？

谢谢

变量

@SuppressLint("InlinedApi")
private static final int PORTRAIT_ORIENTATION = Build.VERSION.SDK_INT < 9
        ? ActivityInfo.SCREEN_ORIENTATION_PORTRAIT
        : ActivityInfo.SCREEN_ORIENTATION_SENSOR_PORTRAIT;

@SuppressLint("InlinedApi")
private static final int LANDSCAPE_ORIENTATION = Build.VERSION.SDK_INT < 9
        ? ActivityInfo.SCREEN_ORIENTATION_LANDSCAPE
        : ActivityInfo.SCREEN_ORIENTATION_SENSOR_LANDSCAPE;

private YouTubePlayer mPlayer = null;
private boolean mAutoRotation = false;

创建时

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    mAutoRotation = Settings.System.getInt(getContentResolver(),
            Settings.System.ACCELEROMETER_ROTATION, 0) == 1;
}

实现OnInitializedListener

@Override
public void onInitializationSuccess(YouTubePlayer.Provider provider, YouTubePlayer player,
        boolean wasRestored) {
    mPlayer = player;
    player.setOnFullscreenListener(this);
    
    if (mAutoRotation) {
        player.addFullscreenControlFlag(YouTubePlayer.FULLSCREEN_FLAG_CONTROL_ORIENTATION
                | YouTubePlayer.FULLSCREEN_FLAG_CONTROL_SYSTEM_UI
                | YouTubePlayer.FULLSCREEN_FLAG_ALWAYS_FULLSCREEN_IN_LANDSCAPE
                | YouTubePlayer.FULLSCREEN_FLAG_CUSTOM_LAYOUT);
    } else {
        player.addFullscreenControlFlag(YouTubePlayer.FULLSCREEN_FLAG_CONTROL_ORIENTATION
                | YouTubePlayer.FULLSCREEN_FLAG_CONTROL_SYSTEM_UI
                | YouTubePlayer.FULLSCREEN_FLAG_CUSTOM_LAYOUT);
    }
}

实现onConfigurationChanged

@Override
public void onConfigurationChanged(Configuration newConfig) {
    super.onConfigurationChanged(newConfig);

    if (newConfig.orientation == Configuration.ORIENTATION_LANDSCAPE) {
        if (mPlayer != null)
            mPlayer.setFullscreen(true);
    } 
    if (newConfig.orientation == Configuration.ORIENTATION_PORTRAIT) {
        if (mPlayer != null)
            mPlayer.setFullscreen(false);
    }
}

@Override
public void onFullscreen(boolean fullsize) {
    if (fullsize) {
        setRequestedOrientation(LANDSCAPE_ORIENTATION);
    } else {
        setRequestedOrientation(PORTRAIT_ORIENTATION);
    }
}

list

 <activity
    android:name="com.sample.android.YouTubePlayerActivity"
    android:configChanges="keyboardHidden|orientation|screenSize"
    android:screenOrientation="sensor"
    android:theme="@android:style/Theme.Black.NoTitleBar.Fullscreen" >
</activity>

我制作了使用最新的 youtube api 的示例 Activity 。

此来源处理“方向问题”、“媒体量问题”、“Youtube 网址解析问题”

1. 这是示例应用程序的 git 项目
