简单记忆游戏卡Android Studio

Question

这是一款简单的记忆游戏卡。它的目的是找到相同的卡片。代码计数尝试。如果我的卡片在5秒的特定时间内没有解开，再次翻转并开始比赛。这是我的代码：

private static Object lock = new Object();

int turns;
private TableLayout mainTable;
private UpdateCardsHandler handler;

@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);



    handler = new UpdateCardsHandler();
    loadImages();
    setContentView(R.layout.main);


   backImage =  getResources().getDrawable(R.drawable.icon);

   /*
   ((Button)findViewById(R.id.ButtonNew)).setOnClickListener(new OnClickListener() {

    @Override
    public void onClick(View v) {
        newGame();

    }


});*/
