Youtube api 为youtube android api实现java代码

我正在构建一个使用youtube API的android应用程序。我已经了解了youtube API的流程，但我不知道如何开始用java构建它。我对使用API完全陌生。有人能提供一个方向吗？

请遵循这种方法。首先，您应该尝试从以下链接下载适用于Android的Youtube播放器库：

您应该首先像这样安装它：项目->菜单：文件>结构>依赖项选项卡>添加->库依赖项

如果不起作用，请尝试以下两种方法之一：

在使用的库的build.gradle文件中添加库的依赖项，并将库粘贴到外部库中

或

只需转到app文件夹中的libs文件夹并将所有.jar（例如库文件）粘贴到那里，这里的技巧是现在进入settings.gradle文件，现在在include之后添加此行include'：app:libs'：app'它肯定会工作

然后，您应该有如下布局：

import android.os.Bundle;
import android.util.Log;
import android.webkit.WebView;
import android.webkit.WebViewClient;
import android.widget.Toast;
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.YouTubePlayerView;
import com.google.api.client.http.HttpRequest;
import com.google.api.client.http.HttpRequestInitializer;
import com.google.api.client.http.javanet.NetHttpTransport;
import com.google.api.client.json.jackson2.JacksonFactory;
import com.google.api.services.youtube.YouTube;
import java.io.IOException;

public class YoutubeActivity extends YouTubeBaseActivity{

    private YouTubePlayerView playerView;
    private YouTube youtube;

    @Override
    protected void onCreate(Bundle bundle) {
        super.onCreate(bundle);

        setContentView(R.layout.activity_youtube);

        youtube = new YouTube.Builder(new NetHttpTransport(),
                new JacksonFactory(), new HttpRequestInitializer() {
            @Override
            public void initialize(HttpRequest hr) throws IOException {}
        }).setApplicationName(this.getString(R.string.app_name)).build();


        playerView = (YouTubePlayerView)findViewById(R.id.player_view);
        playerView.initialize("Your API Key", new YouTubePlayer.OnInitializedListener() {
            @Override
            public void onInitializationSuccess(YouTubePlayer.Provider provider, YouTubePlayer youTubePlayer, boolean b) {
                if(!b){
                    String videoId = getIntent().getExtras().getString("videoID");
                    youTubePlayer.cueVideo(videoId);
                }
            }

            @Override
            public void onInitializationFailure(YouTubePlayer.Provider provider, YouTubeInitializationResult youTubeInitializationResult) {
                Toast.makeText(getApplicationContext(), getString(R.string.failed), Toast.LENGTH_LONG).show();
            }
        });
    }

}

如果你想在商店上发布应用程序，你必须禁用youtube视频播放，否则应用程序将被拒绝
