多個YouTube播放器在一個活動

Question

我使用的是Android版YouTube播放器API爲這裏概述：https://developers.google.com/youtube/android/player/

但是，我不能讓一個以上的視頻到我的活動一次。我試圖簡單地把兩個YouTubePlayerViews進活動，像這樣：

activity_main.xml中

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" 
    android:layout_width="match_parent" 
    android:layout_height="match_parent" 
    android:orientation="vertical" 
    android:paddingBottom="@dimen/activity_vertical_margin" 
    android:paddingLeft="@dimen/activity_horizontal_margin" 
    android:paddingRight="@dimen/activity_horizontal_margin" 
    android:paddingTop="@dimen/activity_vertical_margin" > 

    <com.google.android.youtube.player.YouTubePlayerView 
     android:id="@+id/view_one" 
     android:layout_width="wrap_content" 
     android:layout_height="wrap_content" /> 

    <com.google.android.youtube.player.YouTubePlayerView 
     android:id="@+id/view_two" 
     android:layout_width="wrap_content" 
     android:layout_height="wrap_content" /> 

</LinearLayout> 

MainActivity.java

package com.example.multidemo; 

import android.os.Bundle; 

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

public class MainActivity extends YouTubeBaseActivity { 
    @Override 
    protected void onCreate(Bundle savedInstanceState) { 
     super.onCreate(savedInstanceState); 
     setContentView(R.layout.activity_main); 

     ((YouTubePlayerView) findViewById(R.id.view_one)).initialize("API key", new YouTubePlayer.OnInitializedListener() { 
      @Override 
      public void onInitializationSuccess(Provider arg0, YouTubePlayer arg1, boolean arg2) { 
       arg1.cueVideo("RpwoN_XlN6Y"); 
      } 

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

     ((YouTubePlayerView) findViewById(R.id.view_two)).initialize("API key", new YouTubePlayer.OnInitializedListener() { 
      @Override 
      public void onInitializationSuccess(Provider arg0, YouTubePlayer arg1, boolean arg2) { 
       arg1.cueVideo("jkk2mMq2x8E"); 
      } 

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

當我嘗試這一點，第一種觀點只是出現黑，而第二個視頻加載。如果我將第二個視頻的onCreate（）中的代碼註釋掉，那麼只會加載第一個視頻。

有沒有辦法讓多個YouTubePlayerViews進入同一個活動？

Answer 1

這可能爲時已晚，但我最近有同樣的問題。希望這對有可能面臨同樣問題的人有所幫助。解決這個問題的方法是使用YoutubePlayerFragments。只要你使用Youtube播放器視圖，你將達到限制多個請求中只有一次初始化的限制。通常，最後一次初始化成功。

我最終動態生成gridlayout並將我的（動態生成的）片段的視圖放置在每個單元格中。然後我在onResume中初始化播放器的實例。一旦初始化成功，您將得到一個球員的句柄，並且您可以在片段上隨機提示不​​同的視頻。

我就粘貼會給你我是多麼構建片段，並做初始化一個想法代碼：

public View onCreateView(LayoutInflater inflater, ViewGroup container, 
     Bundle savedInstanceState) 
{ 
    mLogger.i("Preparing Youtube view for fragment .."); 
    mFragmentHeight = CustomFragment.getFragmentHeight(mNumScreens,mNumColumns); 
    mFragmentWidth = CustomFragment.getFragmentWidth(mNumColumns); 

    LinearLayout linearLayout = new LinearLayout(getActivity()); 
    GridLayout.LayoutParams gridparams = new GridLayout.LayoutParams(); 
    gridparams.rowSpec = GridLayout.spec(mGridRow); 
    gridparams.columnSpec = GridLayout.spec(mGridColumn); 
    gridparams.height = mFragmentHeight; 
    gridparams.width = mFragmentWidth; 
    linearLayout.setLayoutParams(gridparams); 
    if(YouTubeApiServiceUtil.isYouTubeApiServiceAvailable(getActivity())== 
      YouTubeInitializationResult.SUCCESS) 
    { 
     View ytView = super.onCreateView(inflater, container, savedInstanceState); 
     linearLayout.addView(ytView); 
    } 
    else 
     mLogger.e("Either youtube service is down," + 
       " or you dont have required version of YouTube app .." + 
       "\nYouTube Fragment will not work as expected.."); 
    mView = linearLayout; 
    mLogger.i("Preparation youtube view for fragment complete.."); 
    return mView; 
} 

@Override 
public void onInitializationFailure(Provider arg0, 
     YouTubeInitializationResult arg1) 
{ 
    mLogger.e("Youtube player initialization failed"); 
} 

@Override 
public void onInitializationSuccess(YouTubePlayer.Provider provider, YouTubePlayer player, 
      boolean wasRestored) 
{ 
    mLogger.i("You tube player initialized successfully.. will attempt to stream.."); 
    mYoutubePlayer = player; 
    setListeners(); 
    try 
    { 
     if (!wasRestored) 
     { 
      if(mPlayListFragment) 
       player.loadPlaylist(getResourceID()); 
      else 
       player.loadVideo(getResourceID()); 
     } 
    } 
    catch(Exception e) 
    { 
     mLogger.e("Error loading playlist/video .."+e); 
    } 

} 

public void onResume() 
{ 
    super.onResume(); 
    initialize(API_KEY, this); 
}
