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

Question

我正在使用 Youtube Player api 在我的应用程序中播放 youtube 视频。我想从假设 36 秒开始视频，并希望在 65 秒左右结束视频。

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

我正在使用 youtubeAndroidPlayer Api。我没有找到任何 Youtubeplayer 设置开始和结束值的方法。有人可以建议我如何设置参数。

而且我还希望使用 youtube api 中的“控件”字段隐藏控件，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);

      }
 }

嗯，你可以利用 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。

这是活动的完整代码：

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方法。希望它能解决你的问题。
