JAVA:

public class GameView extends SurfaceView implements SurfaceHolder.Callback, View.OnTouchListener, Runnable{	private GameActivity gameActivity;    private SurfaceHolder holder;		//-- 构造、初始化 --    public GameView(Context context)    {        super(gameActivity);        getHolder().addCallback(this);        this.setOnTouchListener(this);        this.gameActivity =( GameActivity ) context;//重点就是这步，强转。        init();        initDraw();    }		//-----------------	// 省略部分^&……%……	//-----------------		    public void goActivity()    {        runState = false;        gameActivity.goGameoverActivity();    }		}

PS:没什么可说的就一个强转。                       作者：一个吃货帅锅
