强迫横向取向创造活动循环

Question

我创建了一个包含许多活动的Android应用程序，我想让其中一个成为横向：

public class tutorialActivity extends Activity implements SurfaceHolder.Callback, MediaPlayer.OnPreparedListener  {

    private SurfaceView   mSurfaceView;
    private MediaPlayer   mMediaPlayer;
    private SurfaceHolder mSurfaceHolder;
    private LinearLayout buttonRegister;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_tutorial);
        buttonRegister = findViewById(R.id.button_register);
        buttonRegister.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View view) {
                // Intent i = new Intent(tutorialActivity.this, MenuActivity.class);
                // startActivity(i);
                finish();
            }
        });

        mSurfaceView = findViewById(R.id.surfaceView);
        mSurfaceHolder = mSurfaceView.getHolder();
        mSurfaceHolder.addCallback(tutorialActivity.this);

    }
}

并指定到我的清单文件中：

<activity android:name=".activities.tutorialActivity"
android:screenOrientation="landscape"
android:theme="@style/AppTheme.base"></activity>

当我无限制地展示此活动的oncreate活动循环时，请帮我解决这个问题

清单：

<activity  
    android:name=".YourActivity"
    android:screenOrientation="landscape">

的活动：

setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_LANDSCAPE);
