Question

我想在我的Android应用中嵌入youtube视频。

但是我无法渲染xml，因此应用程序崩溃了。

XML

<LinearLayout 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"
    android:orientation="vertical"
    tools:context=".WelcomePage">
    <com.google.android.youtube.player.YouTubePlayerView
        android:id="@+id/youtube_view"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"/>
</LinearLayout>

WelcomePage.java

public class WelcomePage extends YouTubeBaseActivity implements YouTubePlayer.OnInitializedListener {

如果有人可以帮助我，我将非常感激。我不知道这里有什么问题。

修改：添加活动代码。

`公共类WelcomePage扩展YouTubeBaseActivity实现了YouTubePlayer.OnInitializedListener {

private static final int RECOVERY_REQUEST = 1;
private YouTubePlayerView youTubeView;

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_welcomepage);

    youTubeView = (YouTubePlayerView) findViewById(R.id.youtube_view);
    youTubeView.initialize(Config.YOUTUBE_API_KEY, this);
}

@Override
public void onInitializationSuccess(Provider provider, YouTubePlayer player, boolean wasRestored) {
    if (!wasRestored) {
        player.cueVideo("fhWaJi1Hsfo"); // Plays https://www.youtube.com/watch?v=fhWaJi1Hsfo
    }
}
@Override
public void onInitializationFailure(Provider provider, YouTubeInitializationResult errorReason) {
    if (errorReason.isUserRecoverableError()) {
        errorReason.getErrorDialog(this, RECOVERY_REQUEST).show();
    } else {
        String error = String.format(getString(R.string.player_error), errorReason.toString());
        Toast.makeText(this, error, Toast.LENGTH_LONG).show();
    }
}

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

protected Provider getYouTubePlayerProvider() {
    return youTubeView;
}

@Override
public boolean onCreateOptionsMenu(Menu menu) {
            return true;
}
@Override
public boolean onOptionsItemSelected(MenuItem item) {
    int id = item.getItemId();

            if (id == R.id.action_settings) {
        return true;
    }

    return super.onOptionsItemSelected(item);
}

}`

感谢。

检查你的strings.xml文件，这就是为什么我得到一个红色的R.id错误...
