 setContentView(R.layout.activity_main);
        mAreaSetView = findViewById(R.id.area_set_view);
        //设置网格的x,y方向的数目
        mAreaSetView.setXYCount(30,20);

        //模拟选中的数据
        HashSet<Point> selectedArea = new HashSet<>();
        selectedArea.add(new Point(20,30));
        selectedArea.add(new Point(21,30));
        selectedArea.add(new Point(22,30));
        selectedArea.add(new Point(23,30));
        selectedArea.add(new Point(24,30));
        selectedArea.add(new Point(25,30));
        selectedArea.add(new Point(26,30));
        selectedArea.add(new Point(27,31));
        selectedArea.add(new Point(20,31));
        selectedArea.add(new Point(21,31));
        selectedArea.add(new Point(22,31));
        selectedArea.add(new Point(23,32));
        selectedArea.add(new Point(24,32));
