Question

我按下按钮开始游戏。每当我点击AVD上的那个按钮，不幸的是程序已经停止，我是Android编程的新手。我尝试谷歌搜索我的问题，似乎代码有问题。谁能帮我？我也分享了我的代码链接，请访问https://www.dropbox.com/sh/hyitjbgda69rkd4/3Iz8WuM5-5

主要活动

public class MainActivity extends Activity 
{

    private Game game1;
    /** Called when the activity is first created. */
    @Override
    public void onCreate(Bundle savedInstanceState) 
    {

        super.onCreate(savedInstanceState);

        setContentView(R.layout.activity_main);

        final Button button = (Button) findViewById(R.id.startbutton);

        button.setOnClickListener(new OnClickListener() 
        {
            public void onClick(View v)
            {
                // Perform action on click
                game1 = new Game(this);
                setContentView(game1);
            }
        }); 
    }
}

游戏课程：

public Game(OnClickListener onClickListener) 
    {
        super((Context) onClickListener);

        caneta = new Paint();

        this.caneta.setARGB(255, 0, 0, 0);
        this.caneta.setAntiAlias(true);
        this.caneta.setStyle(Style.STROKE);
        this.caneta.setStrokeWidth(5);

        l = this.getWidth();
        a = this.getHeight();

        singlesquare = new Cell[x][y];

        int xss = l / x;
        int yss = a / y;

        for (int z = 0; z < y; z++) 
        {
            for (int i = 0; i < x; i++) 
            {
                singlesquare[z][i] = new Empty(xss * i, z * yss);
            }
        }
    }

你真的不应该多次打电话给setContentView()。是导致错误的那条线吗？此外，game1的对象类型似乎不是视图。

程序已停止在AVD中
