如何在YouTube播放器活动中添加应用栏?

如何在YouTube播放器中添加操作栏？

我正在尝试在此活动中添加操作栏，但由于它没有扩展到AppCompatActivity这就是为什么我在getSupportActionBar();中遇到错误的原因。如果我用AppCompatActivity替换YouTubeBaseActivity，我也会收到错误。谁能帮我解决这个问题？

public class ActivityPlayer extends YouTubeBaseActivity implements YouTubePlayer.OnInitializedListener {
public String DEVELOPER_KEY = "key";
public String YOUTUBE_VIDEO_CODE = "5z-Roo_NpI4";
private static final int RECOVERY_DIALOG_REQUEST = 1;
YouTubePlayerView youTubeView;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setupActionBar();
setContentView(R.layout.activity_main);
youTubeView = (YouTubePlayerView) findViewById(R.id.youtube_player);
youTubeView.initialize(DEVELOPER_KEY, this);
}
private void setupActionBar() {
ActionBar actionBar = getSupportActionBar();
if (actionBar != null) {
actionBar.setDisplayHomeAsUpEnabled(true);
}
}
@Override
public boolean onCreateOptionsMenu(final Menu menu) {
getMenuInflater().inflate(R.menu.options_menu, menu);
return true;
}
@Override
public boolean onOptionsItemSelected(MenuItem item) {
switch (item.getItemId()) {
case android.R.id.home:
finish();
return true;
}
return true;
}
@Override
public void onInitializationFailure(YouTubePlayer.Provider provider, YouTubeInitializationResult errorReason) {
if (errorReason.isUserRecoverableError()) {
errorReason.getErrorDialog(this, RECOVERY_DIALOG_REQUEST).show();
} else {
Snackbar.make(youTubeView, "There was an error initializing the video player.", Snackbar.LENGTH_LONG).setDuration(5000).show();
}
}
@Override
public void onInitializationSuccess(YouTubePlayer.Provider provider, YouTubePlayer player, boolean wasRestored) {
if (!wasRestored) {
player.loadVideo(YOUTUBE_VIDEO_CODE);
player.setPlayerStyle(YouTubePlayer.PlayerStyle.CHROMELESS);
}
}
@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
if (requestCode == RECOVERY_DIALOG_REQUEST) {
getYouTubePlayerProvider().initialize(DEVELOPER_KEY, this);
}
}
@Override
public void onBackPressed() {
finish();
}
private YouTubePlayer.Provider getYouTubePlayerProvider() {
return (YouTubePlayerView) findViewById(R.id.youtube_player);
}
}

Answer 1

我和你有同样的问题，我正在发布一个答案，以防你或其他人仍然需要变通。忘记YoutubeBaseActivity，专注于YoutubePlayerSupportFragment，因为 Fragment 可让您根据需要设置活动。也有YoutubePlayerFragment，但它的支持版本与 android 支持库配合得更好。

这是我使用的步骤：

1. 使您的活动扩展应用兼容活动

   public class ActivityPlayer extends AppCompatActivity {
   

2. 在扩展 AppCompatActivity 的当前活动的 xml 布局中添加框架布局 (activity_main.xml)

   <FrameLayout
   android:id="@+id/flYoutube"
   android:layout_width="match_parent"
   android:layout_height="wrap_content"
   android:layout_centerHorizontal="true"
   android:visibility="visible" />
   

3. 创建 YoutubeFragment 扩展了 Fragment，其中包含fragment_youtube.xml布局和 FrameLayout。在onCreateView中，创建一个YoutubePlayerSupportFragment实例，并将fragment_youtube.xml中的FrameLayout替换为YoutubePlayerSupportFragment的实例。

   public class YoutubeFragment extends Fragment {
   private static final String YOUTUBE_API_KEY = "8S7K4hEVhgOQ87501j-FAKE-KEY";
   // the fragment initialization parameters, e.g. ARG_ITEM_NUMBER
   private static final String VIDEO_ID = "VIDEO_ID";
   // TODO: Rename and change types of parameters
   private String videoId;
   public YoutubeFragment() {
   // Required empty public constructor
   }
   
   public static YoutubeFragment newInstance(String videoId) {
   YoutubeFragment fragment = new YoutubeFragment();
   Bundle args = new Bundle();
   args.putString(VIDEO_ID, videoId);
   fragment.setArguments(args);
   return fragment;
   }
   @Override
   public void onCreate(Bundle savedInstanceState) {
   super.onCreate(savedInstanceState);
   if (getArguments() != null) {
   videoId = getArguments().getString(VIDEO_ID);
   }
   }
   @Override
   public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
   // Inflate the layout for this fragment
   View rootView = inflater.inflate(R.layout.fragment_youtube, container, false);
   YouTubePlayerSupportFragment youTubePlayerFragment = YouTubePlayerSupportFragment.newInstance();
   FragmentTransaction transaction = getChildFragmentManager().beginTransaction();
   transaction.replace(R.id.flYoutubePlayer, youTubePlayerFragment).commit();
   youTubePlayerFragment.initialize(YOUTUBE_API_KEY, new YouTubePlayer.OnInitializedListener() {
   @Override
   public void onInitializationSuccess(YouTubePlayer.Provider arg0, YouTubePlayer youTubePlayer, boolean b) {
   if (!b) {
   //youTubePlayer.setFullscreen(true);
   youTubePlayer.loadVideo(videoId);
   //yoTubePlayer.play();
   }
   }
   @Override
   public void onInitializationFailure(YouTubePlayer.Provider arg0, YouTubeInitializationResult arg1) {
   // TODO Auto-generated method stub
   }
   });
   return rootView;
   }
   }
   

4. 在fragment_youtube.xml中创建第二个框架布局

   <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"
   tools:context="jfsl.ayibopost.fragments.YoutubeFragment">
   <FrameLayout
   android:id="@+id/flYoutubePlayer"
   android:layout_width="match_parent"
   android:layout_height="200dp"></FrameLayout>
   </RelativeLayout>
   

5. 在 PlayerActivity onCreate() 中要做的最后一件事是创建你自己创建的 YoutubeFragment 的实例，并通过片段事务将activity_main.xml中的帧布局替换为该 YoutubeFragment 实例：

   // Create Youtube Fragment instance by passing a Youtube Video ID
   YoutubeFragment youtubeFragment = YoutubeFragment.newInstance("2zNSgSzhBfM");
   getSupportFragmentManager().beginTransaction()
   .replace(R.id.flYoutube, youtubeFragment).commit();
   

你完成了。

Answer 2

你应该实现一个AppCompatCallback接口。
