今天偶遇以github上gesturelock关于手势锁的一个例子（有兴趣的去搜索下看看），于是下载下来研究，无奈基本没有注释，代码上存在一些问题(当设置gravity=center_vertical无法进行手势选择，无意中发现的)，于是借鉴这位仁兄的代码，自己重写写了一个，修复了一些问题，加入一些基本的自定义属性，在此先感谢这位兄弟~。

先上图，默认效果图：

当然可以自定义数量啊，颜色神马的，自定义效果图：

如果你有艺术细胞，可以给我推荐几个颜色，无奈个人审美有问题~

1、整体思路

a、自定义了一个RelativeLayout(GestureLockViewGroup)在里面会根据传入的每行的个数，生成多个GestureLockView（就是上面一个个小圈圈），然后会自动进行布局，里面的宽度，间距，内圆的直径，箭头的大小神马的都是百分比实现的，所以大胆的设置你喜欢的个数，只要你没有密集恐惧症~

b、GestureLockView有三个状态，没有手指触碰、手指触碰、和手指抬起，会根据这三个状态绘制不同的效果，以及抬起时的小箭头需要旋转的角度，会根据用户选择的GestureLockView，进行计算，在GestureLockViewGroup为每个GestureLockView设置

c、GestureLockViewGroup主要就是判断用户ACTION_MOVE，ACTION_DOWN ， ACTION_UP时改变选中的GestureLockView的状态，并且记录下来，提供一定的回调。

下面开始看代码：

2、声明一些用户可以设置的属性：

<?xml version="1.0" encoding="utf-8"?>
<resources>

    <attr name="color_no_finger_inner_circle" format="color" />
    <attr name="color_no_finger_outer_circle" format="color" />
    <attr name="color_finger_on" format="color" />
    <attr name="color_finger_up" format="color" />
    <attr name="count" format="integer" />
    <attr name="tryTimes" format="integer" />

    <declare-styleable name="GestureLockViewGroup">
        <attr name="color_no_finger_inner_circle" />
        <attr name="color_no_finger_outer_circle" />
        <attr name="color_finger_on" />
        <attr name="color_finger_up" />
