Android手势密码实现方案

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;/** *  * 手势密码图案提示 * @author wulianghuan * */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);}}@Overrideprotected 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();}}}@Overrideprotected 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viewgestureDrawline = 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);}@Overrideprotected 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);}}@Overrideprotected 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。

package com.wujay.fund.widget;import java.util.ArrayList;import java.util.HashMap;import java.util.List;import java.util.Map;import com.wujay.fund.common.AppUtil;import
