Android手势密码实现

技术分享

二、实现思路:

1. 正上方的提示区域,用一个类(LockIndicator.java)来实现,自定义view来绘制9个提示图标;

2. 手势密码绘制区域,用一个类(GestureContentView.java)来实现,它继承自ViewGroup里面, 添加9个ImageView来表示图标, 在onLayout()方法中设置它们的位置;

3. 手势路径绘制, 用一个类(GestureDrawline.java)来实现,复写onTouchEvent()方法,在这个方法里面监听TouchEvent事件: ACTION_DOWN、ACTION_MOVE、ACTION_UP事件,来绘制手势连接不同点之间的路径;

4. 9个点的对象,用一个类(GesturePoint.java)来实现,保存它的位置、状态、背景图片等相关信息;

5. 手势密码的获取,判断手指当前的位置,根据滑动路径经过的点,按顺序保存绘制的点的顺序(这里的点顺序从上到下分别是:1,2,3,4,5,6,7,8,9),不能有重复的点。

 

三、代码实现步骤:

1.要用一个类来表示这9个点中的第一个点。里面保留有当前点的上下左右的各个位置等属性

2.自定义GroupView,用来装9个点,9个点的显示是通过ImageView。复写onLayout这个方法,让点按需求排列

3.定义一个可以画线的View,复写onTouchEvent方法,在这个方法里面进行画直线的操作

4.判断用户手指当前的位置,取出当前的位置去与那9个点中的每个点的位置进行比较,如果用户点的位置在某一个点之内,那么当那个点置换背景图片。

具体实现代码如下:
