Android手势密码的实现

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); } } @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。

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 com.wujay.fund.common.Constants;

} } return null; } // 画位图 @Override protected void onDraw(Canvas canvas) { // super.onDraw(canvas); canvas.drawBitmap(bitmap, 0, 0, null); } // 触摸事件 @Override public boolean onTouchEvent(MotionEvent event) { if (isDrawEnable == false) { // 当期不允许绘制 return true; } paint.setColor(Color.rgb(245, 142, 33));// 设置默认连线颜色 switch (event.getAction()) { case MotionEvent.ACTION_DOWN: mov_x = (int) event.getX(); mov_y = (int) event.getY(); // 判断当前点击的位置是处于哪个点之内 currentPoint = getPointAt(mov_x, mov_y);

5.GestureVerifyActivity.java 手势密码校验界面
