大佬教程收集整理的这篇文章主要介绍了Android手势密码的实现，大佬教程大佬觉得挺不错的，现在分享给大家，也给大家做个参考。

一、大致界面介绍：

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

  } 
  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,patternWidth,patternHeight); 
      patternNoraml.setBounds(0,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;

  }

   */ 
  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 com.wujay.fund.widget.GestureDrawline.GestureCallBACk; 
/**

 */ 
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
