这几个月都是在做招财进宝项目，一个高收益低风险的理财APP，有兴趣的可以下载玩玩，收益不错哦！！！

前段时间因产品需求，做了一个手势密码，跟支付宝的手势密码类似，这里跟大家分享交流一下我实现的方式吧。
这篇来分享一下绘制手势密码的实现（主要是设置手势密码、校验手势密码）：
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：
1. LockIndicator.java 图案提示类
package com.snda.fund.widget;
import com.snda.fund.R;
import android.content.Context;
import android.content.res.TypedArray;
import android.graphics.Canvas;
import android.graphics.Paint;
import android.graphics.Paint.Style;
import android.graphics.drawable.Drawable;
import android.os.PowerManager;
import android.text.TextUtils;
import android.util.AttributeSet;
import android.util.Log;
import android.view.View;
/**

*/
public class LockIndicator extends View {
private int numRow = 3; // 行
private int numColum = 3; // 列
private int patternWidth = 40;
private int patternHeight = 40;
private int f = 5;
private int g = 5;
private int strokeWidth = 3;
private Paint paint = null;
private Drawable patternNoraml = null;
private Drawable patternPressed = null;
private String lockPassStr; // 手势密码
public LockIndicator(Context paramContext) {
super(paramContext);
}
public LockIndicator(Context paramContext, AttributeSet paramAttributeSet) {
super(paramContext, paramAttributeSet, 0);
paint = new Paint();
paint.setAntiAlias(true);
paint.setStrokeWidth(strokeWidth);
paint.setStyle(Paint.Style.STROKE);
patternNoraml = getResources().getDrawable(R.drawable.lock_pattern_node_normal);
patternPressed = getResources().getDrawable(R.drawable.lock_pattern_node_pressed);
if (patternPressed != null) {
patternWidth = patternPressed.getIntrinsicWidth();
patternHeight = patternPressed.getIntrinsicHeight();
this.f = (patternWidth / 4);
this.g = (patternHeight / 4);
patternPressed.setBounds(0, 0, patternWidth, patternHeight);
patternNoraml.setBounds(0, 0, patternWidth, patternHeight);
}
}
@Override
protected void onDraw(Canvas canvas) {
if ((patternPressed == null) || (patternNoraml == null)) {
return;
}
// 绘制3*3的图标
for (int i = 0; i < numRow; i++) {
for (int j = 0; j < numColum; j++) {
paint.setColor(-16777216);
int i1 = j * patternHeight + j * this.g;
int i2 = i * patternWidth + i * this.f;
canvas.save();
canvas.translate(i1, i2);
String curNum = String.valueOf(numColum * i + (j + 1));
if (!TextUtils.isEmpty(lockPassStr)) {
if (lockPassStr.indexOf(curNum) == -1) {
// 未选中
patternNoraml.draw(canvas);
} else {
// 被选中
patternPressed.draw(canvas);
}
} else {
// 重置状态
patternNoraml.draw(canvas);
}
canvas.restore();
}
}
}
@Override
protected void onMeasure(int paramInt1, int paramInt2) {
if (patternPressed != null)
setMeasuredDimension(numColum * patternHeight + this.g
* (-1 + numColum), numRow * patternWidth + this.f
* (-1 + numRow));
}
/**
* 请求重新绘制
* @param paramString 手势密码字符序列
*/
public void setPath(String paramString) {
lockPassStr = paramString;
invalidate();
}
}
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：
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。

mTextTip.setText(Html
.fromHtml("<font color='#c70c1e'>密码错误</font>"));
// 左右移动动画
Animation shakeAnimation = AnimationUtils.loadAnimation(GestureVerifyActivity.this, R.anim.shake);
mTextTip.startAnimation(shakeAnimation);
}
});
// 设置手势解锁显示到哪个布局里面
mGestureContentView.setParentView(mGestureContainer);
}
private void setUpListeners() {
mTextCancel.setOnClickListener(this);
mTextForget.setOnClickListener(this);
mTextOther.setOnClickListener(this);
}
private String getProtectedMobile(String phoneNumber) {
if (TextUtils.isEmpty(phoneNumber) || phoneNumber.length() < 11) {
return "";
}
StringBuilder builder = new StringBuilder();
builder.append(phoneNumber.subSequence(0,3));
builder.append("****");
builder.append(phoneNumber.subSequence(7,11));
return builder.toString();
}
@Override
public void onClick(View v) {
switch (v.getId()) {
case R.id.text_cancel:
this.finish();
break;
default:
break;
}
}
}
以上是手势密码实现的关键代码，我把项目中的模块代码整理出来，新建了一个project，供大家分享和交流
