在 Fragment 中初始化 YouTube 播放器 [英] Initializing YouTube player in Fragment

问题描述

请耐心等待，因为我对 Android 还是很陌生.我正在尝试在片段类中初始化 Youtube 播放器.Google 已经提供了在 Activity 中初始化的方法，如下所示:

Please bear up with me as I am pretty new to Android. I am trying to initialize Youtube player in a fragment class. Google has already provided method to initialize in Activity which goes as follows:

package com.examples.youtubeapidemo;

import com.google.android.youtube.player.YouTubeBaseActivity;
import com.google.android.youtube.player.YouTubePlayer;
import com.google.android.youtube.player.YouTubePlayerView;

import android.os.Bundle;


public class PlayerViewDemoActivity extends YouTubeFailureRecoveryActivity {

  @Override
  public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.playerview_demo);

    YouTubePlayerView youTubeView = (YouTubePlayerView) findViewById(R.id.youtube_view);
    youTubeView.initialize(DeveloperKey.DEVELOPER_KEY, this);
  }

  @Override
  public void onInitializationSuccess(YouTubePlayer.Provider provider, YouTubePlayer player,
      boolean wasRestored) {
    if (!wasRestored) {
      player.cueVideo("wKJ9KzGQq0w");
    }
  }

  @Override
  protected YouTubePlayer.Provider getYouTubePlayerProvider() {
    return (YouTubePlayerView) findViewById(R.id.youtube_view);
  }

}

我尝试使用此代码但它不起作用:

I tried using this code but its not working:

public class TabFragment5 extends YouTubePlayerFragment implements YouTubePlayer.OnInitializedListener {
    /** (non-Javadoc)
     * @see android.support.v4.app.Fragment#onCreateView(android.view.LayoutInflater, android.view.ViewGroup, android.os.Bundle)
     */
    public View onCreateView(LayoutInflater inflater, ViewGroup container,
            Bundle savedInstanceState) {
        if (container == null) {
            return null;
        }
           YouTubePlayerFragment yf =  newInstance(); //new  YouTubePlayerFragment();
        yf.initialize("dsds", this);
        return (LinearLayout)inflater.inflate(R.layout.tab_frag4_layout, container, false);
    }

    @Override
    public void onInitializationFailure(Provider arg0,
            YouTubeInitializationResult arg1) {
        // TODO Auto-generated method stub

    }

      @Override
      public void onInitializationSuccess(YouTubePlayer.Provider provider, YouTubePlayer player,
          boolean wasRestored) {
        if (!wasRestored) {
          player.cueVideo("nCgQDjiotG0");
        }
      }
}

如果有人可以为片段提供等效的 API，我将不胜感激.

I would be very grateful if anyone can provide equivalent API for fragment.

谢谢

推荐答案

尝试使用下面的示例:

片段.xml

<RelativeLayout 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"
    tools:context=".VideoFragment" >
    <fragment
        android:name="com.google.android.youtube.player.YouTubePlayerFragment"
        android:id="@+id/youtubeplayerfragment"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"/>
</RelativeLayout>

片段创建

Fragment creation

VideoFragment videoFragment = VideoFragment.newInstance(VIDEO_ID);

视频片段

public class VideoFragment extends YouTubePlayerSupportFragment {
    public static final String DEVELOPER_ANDROID_KEY = "KEY";

    public static VideoFragment newInstance(String url) {
        VideoFragment videoFragment = new VideoFragment();
        Bundle bundle = new Bundle();
        bundle.putString("url", url);
        videoFragment.setArguments(bundle);
        videoFragment.init(0);
        return videoFragment;
    }

    private void init(final int time) {
        initialize(DEVELOPER_ANDROID_KEY, new OnInitializedListener() {

            @Override
            public void onInitializationFailure(Provider arg0, YouTubeInitializationResult arg1) {
            }

            @Override
            public void onInitializationSuccess(YouTubePlayer.Provider provider, YouTubePlayer
                                                             player, boolean wasRestored) {
                mPlayer.setPlayerStyle(YouTubePlayer.PlayerStyle.DEFAULT);
                id = getArguments().getString("url");
                if (!wasRestored) {
                    mPlayer.loadVideo(id, time);
                }
            }
        });
     }   
 }
