我正在使用此处概述的 Youtube Android Player API:https://developers.google.com/youtube/android/player/

但是，我无法一次将多个视频添加到我的 Activity 中。我试着简单地将两个 YouTubePlayerView 放入 Activity 中，如下所示:

activity_main.xml

<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>

主要 Activity .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) {
            }
        });
    }
}

当我尝试这个时，第一个 View 只是黑色，而第二个视频加载。如果我为第二个视频注释掉 onCreate() 中的代码，那么将只加载第一个视频。

有没有办法让多个 YouTubePlayerView 进入同一个 Activity ？

最佳答案

这可能为时已晚，但我最近遇到了同样的问题。希望这对可能面临同样问题的人有所帮助。解决这个问题的技巧是改用 YoutubePlayerFragments。只要您使用 Youtube 播放器 View ，您就会达到在多个请求中仅完成一次初始化的限制。通常最后一个初始化成功。

我最终动态生成网格布局并将我的(动态生成的) fragment View 放置在每个单元格中。然后我在 onResume 中初始化播放器实例。初始化成功后，您将获得播放器的句柄，您可以在 fragment 上随机插入不同的视频。

我将只粘贴代码，让您了解我是如何构建 fragment 和进行初始化的:

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);
}
