Question

我想用这段代码启动我的Level1.class活动：

public class OverviewChapter1 extends Scene

SceneManager.mainScene.runOnUiThread(new Runnable() 
{
    public void run() 
    {
        SceneManager.mainScene.startActivity(new Intent(SceneManager.mainScene, Level1.class));
        SceneManager.mainScene.finish();
    }
});

但是，我收到此错误消息：

FATAL EXCEPTION: main
android.content.ActivityNotFoundException: Unable to find explicit activity class 
{de.davidtheobald.thorsrevengeapp/de.davidtheobald.thorsrevengeapp.chapter1.Level1}; 
have you declared this activity in your AndroidManifest.xml?

我如何在清单文件中定义活动？

Answer 1

在Level1.class文件中为AndriodManifest.xml添加活动 ...

<activity android:name="YourPackage.Level1"> </activity>
