Question

我正试图在Android Studio中解决这个问题，但我找不到找到开始第二堂课的方法。

public FrontViewPanel(Context context) {
    super(context);
    this.mContext = context;
}

和

line 41     Intent intent = new Intent(mContext, GamePanel.class);
line 42     mContext.startActivity(intent);

不起作用：

                                                                                     at android.app.Activity.startActivity(Activity.java:3598)
                                                                                     at samuel.kaufmann.myapplication.FrontViewPanel.onTouchEvent(**FrontViewPanel.java:42**)

还有另一个命令来启动GamePanel类吗？
