一、大致界面介绍：
图1
图2
图3
图4
图1：手势密码绘制界面 【主要是绘制上方的9个提示图标和9个宫格密码图标】
图2：设置手势密码 【监听手势的输入，touchevent的事件处理，获取输入的手势密码，同时显示在上方的提示区域】
图3：再绘制一次，两次密码不一致提示界面 【这里在实现的时候，错误提示文字加了“左右晃动的动画”，错误路径颜色标记为红色】
图4：校验手势密码，输入的密码错误，给予红色路径+错误文字提示
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：

2.gesturecontentview.java ?手势密码容器类
它继承viewgroup，通过addview()方法添加子viewe，手势密码的9个输入点(gesturepoint)、gesturedrawline手势密码路径都放在这个容器当中，下面是它的具体实现方法：

private context context;
private boolean isverify;
private gesturedrawline gesturedrawline;
/**

*/
public gesturecontentview(context context, boolean isverify, string password, gesturecallback callback) {
super(context);
screendispaly = apputil.getscreendispaly(context);
blockwidth = screendispaly[0]/3;
this.list = new arraylist<gesturepoint>();
this.context = context;
this.isverify = isverify;
// 添加9个图标
addchild();
// 初始化一个可以画线的view
gesturedrawline = new gesturedrawline(context, list, isverify, password, callback);
}
private void addchild(){
for (int i = 0; i < 9; i++) {

image.setbackgroundresource(r.drawable.gesture_node_normal);
this.addview(image);
invalidate();
// 第几行

int bottomy = row*blockwidth+blockwidth-blockwidth/basenum;
gesturepoint p = new gesturepoint(leftx, rightx, topy, bottomy, image,i+1);
this.list.add(p);
}
}
public void setparentview(viewgroup parent){
// 得到屏幕的宽度
int width = screendispaly[0];
layoutparams layoutparams = new layoutparams(width, width);
this.setlayoutparams(layoutparams);
gesturedrawline.setlayoutparams(layoutparams);
parent.addview(gesturedrawline);
parent.addview(this);
}
@override
protected void onlayout(boolean changed, int l, int t, int r, int b) {
for (int i = 0; i < getchildcount(); i++) {
//第几行
int row = i/3;
//第几列
int col = i%3;
view v = getchildat(i);
v.layout(col*blockwidth+blockwidth/basenum, row*blockwidth+blockwidth/basenum,
col*blockwidth+blockwidth-blockwidth/basenum, row*blockwidth+blockwidth-blockwidth/basenum);
}
}
@override
protected void onmeasure(int widthmeasurespec, int heightmeasurespec) {
super.onmeasure(widthmeasurespec, heightmeasurespec);
// 遍历设置每个子view的大小
for (int i = 0; i < getchildcount(); i++) {
view v = getchildat(i);
v.measure(widthmeasurespec, heightmeasurespec);
}
}
/**

gesturedrawline.cleardrawlinestate(delaytime);
}
}
