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 *** 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：
1.LockIndicator.java 图案提示类

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：
package com.wujay.fund.Widget; import java.util.ArrayList; import java.util.List; import androID.content.Context; import androID.vIEw.VIEw; import androID.vIEw.VIEwGroup; import androID.Widget.ImageVIEw; import com.wujay.fund.R; import com.wujay.fund.common.AppUtil; import com.wujay.fund.entity.GesturePoint; import com.wujay.fund.Widget.GestureDrawline.GestureCallBack; /** * 手势密码容器类 * */ public class GestureContentVIEw extends VIEwGroup { private int baseNum = 6; private int[] screendispaly; /** * 每个点区域的宽度 */ private int blockWIDth; /** * 声明一个集合用来封装坐标集合 */ private List<GesturePoint> List; private Context context; private boolean isverify; private GestureDrawline gestureDrawline; /** * 包含9个ImageVIEw的容器，初始化 * @param context * @param isverify 是否为校验手势密码 * @param passWord 用户传入密码 * @param callBack 手势绘制完毕的回调 */ 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++) { ImageVIEw image = new ImageVIEw(context); image.setBackgroundResource(R.drawable.gesture_node_normal); this.addVIEw(image); invalIDate(); // 第几行 int row = i / 3; // 第几列 int col = i % 3; // 定义点的每个属性 int leftX = col*blockWIDth+blockWIDth/baseNum; int topY = row*blockWIDth+blockWIDth/baseNum; int rightX = col*blockWIDth+blockWIDth-blockWIDth/baseNum; 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); } } /** * 保留路径delayTime时间长 * @param delayTime */ public voID clearDrawlinestate(long delayTime) { gestureDrawline.clearDrawlinestate(delayTime); } }3.GestureDrawline.java 手势密码路径绘制类
根据OntouchEvent方法的不同事件，ACTION_DOWN、ACTION_MOVE、ACTION_UP分别处理不同的逻辑。
