YouTube 播放器 API

获取 Android API 密钥：

首先，你需要使用 java keytool 在你的机器上获取 SHA-1 指纹。在 cmd / terminal 中执行以下命令以获取 SHA-1 指纹。

keytool -list -v -keystore ~/.android/debug.keystore -alias androiddebugkey -storepass android -keypass android

MainActivity.java

public class Activity extends YouTubeBaseActivity implements YouTubePlayer.OnInitializedListener {

    private static final int RECOVERY_DIALOG_REQUEST = 1;

    // YouTube player view
    private YouTubePlayerView youTubeView;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        requestWindowFeature(Window.FEATURE_NO_TITLE);
        getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN,
                WindowManager.LayoutParams.FLAG_FULLSCREEN);

        setContentView(R.layout.activity_main);

        youTubeView = (YouTubePlayerView) findViewById(R.id.youtube_view);

        // Initializing video player with developer key
        youTubeView.initialize(Config.DEVELOPER_KEY, this);

    }

    @Override
    public void onInitializationFailure(YouTubePlayer.Provider provider,
                                        YouTubeInitializationResult errorReason) {
        if (errorReason.isUserRecoverableError()) {
            errorReason.getErrorDialog(this, RECOVERY_DIALOG_REQUEST).show();
        } else {
            String errorMessage = String.format(
                    getString(R.string.error_player), errorReason.toString());
            Toast.makeText(this, errorMessage, Toast.LENGTH_LONG).show();
        }
    }

    @Override
    public void onInitializationSuccess(YouTubePlayer.Provider provider,
                                        YouTubePlayer player, boolean wasRestored) {
        if (!wasRestored) {

            // loadVideo() will auto play video
            // Use cueVideo() method, if you don't want to play it automatically
            player.loadVideo(Config.YOUTUBE_VIDEO_CODE);

            // Hiding player controls
            player.setPlayerStyle(YouTubePlayer.PlayerStyle.CHROMELESS);
        }
    }

    @Override
    protected void onActivityResult(int requestCode, int resultCode, Intent data) {
        if (requestCode == RECOVERY_DIALOG_REQUEST) {
            // Retry initialization if user performed a recovery action
            getYouTubePlayerProvider().initialize(Config.DEVELOPER_KEY, this);
        }
    }

    private YouTubePlayer.Provider getYouTubePlayerProvider() {
        return (YouTubePlayerView) findViewById(R.id.youtube_view);
    }    
}

现在创建 Config.java 文件。此文件包含 Google Console API 开发人员密钥和 YouTube 视频 ID

Config.java

public class Config {

    // Developer key
    public static final String DEVELOPER_KEY = "AIzaSyDZtE10od_hXM5aXYEh6Zn7c6brV9ZjKuk";

    // YouTube video id
    public static final String YOUTUBE_VIDEO_CODE = "_oEA18Y8gM0";
}

xml 文件

<com.google.android.youtube.player.YouTubePlayerView
                android:id="@+id/youtube_view"
                android:layout_width="match_parent"
                android:layout_height="wrap_content"
                android:layout_marginBottom="30dp" />
