如何在youtube Android播放器中为youtube视频提供开始和结束参数

Question

我在应用程序中使用Youtube Player api播放Youtube视频。我想从36秒开始视频，并想在65秒结束视频。

示例：https://www.youtube.com/v/BmOpD46eZoA?start=36&end=65

我正在使用youtubeAndroidPlayerApi。我没有找到Youtubeplayer设置开始值和结束值的任何方法。有人能建议我如何设置参数吗。

我还希望使用youtubeapi中的"controls"字段来隐藏控件，但我没有找到任何方法来隐藏它。

我的xml:

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:paddingBottom="@dimen/activity_vertical_margin"
    android:paddingLeft="@dimen/activity_horizontal_margin"
    android:paddingRight="@dimen/activity_horizontal_margin"
    android:paddingTop="@dimen/activity_vertical_margin"
    android:orientation="vertical"
    tools:context=".MainActivity" >
    <TextView
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="http://android-er.blogspot.com/"
        android:textStyle="bold"
        android:layout_gravity="center_horizontal"
        android:autoLink="web" />
    <com.google.android.youtube.player.YouTubePlayerView
        android:id="@+id/youtubeplayerview"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"/>
</LinearLayout>

我的活动：

public class MainActivity extends YouTubeBaseActivity implements
YouTubePlayer.OnInitializedListener{
 public static final String API_KEY = "AIzaSyCe6tORd9Ch4lx-9Ku5SQ476uS9OtZYsWA";
 public static final String VIDEO_ID = "xyoajjlPt_o";
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        YouTubePlayerView youTubePlayerView = (YouTubePlayerView)findViewById(R.id.youtubeplayerview);
        youTubePlayerView.initialize(API_KEY, this);

    }
 @Override
 public void onInitializationFailure(Provider provider,
   YouTubeInitializationResult result) {
  Toast.makeText(getApplicationContext(), 
    "onInitializationFailure()", 
    Toast.LENGTH_LONG).show();
 }
 @Override
 public void onInitializationSuccess(Provider provider, YouTubePlayer player,
   boolean wasRestored) {
  if (!wasRestored) {
        player.cueVideo(VIDEO_ID);
      }
 }

好吧，您可以使用Handler来跟踪视频的当前运行时间。当以毫秒为单位的时间达到您想要停止视频的点时，只需调用player.pause()方法即可。

以下是活动的完整代码：

public class MyActivity extends YouTubeBaseActivity implements YouTubePlayer.OnInitializedListener{
    public static final String API_KEY = "AIzaSyCe6tORd9Ch4lx-9Ku5SQ476uS9OtZYsWA";
    public static final String VIDEO_ID = "xyoajjlPt_o";
    private static YouTubePlayer player;
    TextView text;
    //this is the end time in milliseconds (65th second)
    public int endTime = 65000; 

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.my_activity);
        text = (TextView) findViewById(R.id.text);
        YouTubePlayerView youTubePlayerView = (YouTubePlayerView)findViewById(R.id.youtubeplayerview);
        youTubePlayerView.initialize(API_KEY, this);
    }
    @Override
    public void onInitializationFailure(Provider provider,
            YouTubeInitializationResult result) {
        Toast.makeText(getApplicationContext(), 
                "onInitializationFailure()", 
                Toast.LENGTH_LONG).show();
    }
    @Override
    public void onInitializationSuccess(Provider provider, YouTubePlayer player, boolean wasRestored) {
        MyActivity.player = player; //necessary to access inside Runnable 
        //start the video at 36th second
        player.loadVideo(VIDEO_ID, 36000);
        final Handler handler = new Handler();
        handler.postDelayed(new Runnable() {
            @Override
            public void run() {
                //For every 1 second, check the current time and endTime
                if(MyActivity.player.getCurrentTimeMillis() <= endTime) { 
                    text.setText("Video Playing at " + MyActivity.player.getCurrentTimeMillis());
                    handler.postDelayed(this, 1000);
                } else {
                    handler.removeCallbacks(this); //no longer required
                    text.setText(" Reached " + endTime);
                    MyActivity.player.pause(); //and Pause the video
                }
            }
        }, 1000);
    }
}

我不确定是否还有其他办法。希望它能解决你的问题。
