Android自定义UI手势密码终结版

之前写过3篇的demo,不过没有集成到真实的企业项目中，这几天正好领到一个手势密码项目，昨天刚好弄完，今天抽空整理下，目前还没有完善，有一些地方需要更改，不过基本的流程都可以跑通了。

源码下载地址：http://xiazai.jb51.net/201610/yuanma/androidgesturelock(jb51.net).rar

先看主界面的入口把、里面有2个button(一个是设置手势密码、一个是校验手势密码)
activity_main.xml

<relativelayout xmlns:android="http://schemas.android.com/apk/res/android" 
 xmlns:tools="http://schemas.android.com/tools" 
 android:layout_width="match_parent" 
 android:layout_height="match_parent" 
 tools:context="com.example.gesturelock.mainactivity" > 
 
 <button 
 android:id="@+id/setting" 
 android:layout_width="wrap_content" 
 android:layout_height="wrap_content" 
 android:layout_alignparentleft="true" 
 android:layout_alignparenttop="true" 
 android:text="设置" /> 
 
 <button 
 android:id="@+id/verify" 
 android:layout_width="wrap_content" 
 android:layout_height="wrap_content" 
 android:layout_alignparenttop="true" 
 android:layout_torightof="@+id/setting" 
 android:text="校验" /> 
 
</relativelayout> 

在看主界面的代码把
mainactivity

package com.example.gesturelock; 
 
import android.app.activity; 
import android.content.intent; 
import android.os.bundle; 
import android.view.menu; 
import android.view.menuitem; 
import android.view.view; 
import android.view.view.onclicklistener; 
import android.widget.button; 
 
public class mainactivity extends activity implements onclicklistener { 
 
 private button setting, verify; 
 
 @override 
 protected void oncreate(bundle savedinstancestate) { 
 super.oncreate(savedinstancestate); 
 setcontentview(r.layout.activity_main); 
 setting = (button) findviewbyid(r.id.setting); 
 verify = (button) findviewbyid(r.id.verify); 
 setting.setonclicklistener(this); 
 verify.setonclicklistener(this); 
 } 
 
 @override 
 public void onclick(view v) { 
 switch (v.getid()) { 
 case r.id.setting: 
 
  startactivity(new intent(this, gestureeditactivity.class)); 
  break; 
 case r.id.verify: 
  startactivity(new intent(this, gestureverifyactivity.class)); 
 
  break; 
 
 default: 
  break; 
 } 
 } 
 
} 

想了想还是先贴数据库把---就是存放手势密码、以及还可以输入的手势密码次数
publicsqliteopenhelper

package com.example.gesturelock; 
 
import android.content.contentvalues; 
import android.content.context; 
import android.database.cursor;

 } 
 @override

接下里再看工具类把--就是输入的手势密码简单md5加密、以及屏幕尺寸工具类

/**

 */ 
package com.example.gesturelock; 
 
import android.content.context; 
import android.view.windowmanager; 
 
public class apputil { 
 
 /** 
 * 获取屏幕分辨�? 
 * @param context 
 * @return 
 */ 
 public static int[] getscreendispaly(context context) { 
 windowmanager windowmanager = (windowmanager) context.getsystemservice(context.window_service); 
 @suppresswarnings("deprecation") 
 int width = windowmanager.getdefaultdisplay().getwidth(); 
 @suppresswarnings("deprecation") 
 int height = windowmanager.getdefaultdisplay().getheight(); 
 int result[] = { width, height }; 
 return result; 
 } 
 
} 

package com.example.gesturelock; 
 
import java.security.messagedigest; 
import java.security.nosuchalgorithmexception; 
 
import android.util.log; 
 
public class md5encodeutil { 
 public static string md5ecode(string gesture){ 
 log.i("gyl","gesture---"+gesture.tostring()); 
 byte[] toencode=gesture.tostring().getbytes(); 
 log.i("gyl","byte[]----"+toencode.tostring()); 
  
 try{ 
  messagedigest md5=messagedigest.getinstance("md5"); 
  md5.reset(); 
  md5.update(toencode); 
  return hexencode(md5.digest()); 
 }catch(nosuchalgorithmexception e){ 
  e.printstacktrace(); 
 } 
 return ""; 
 } 
 public static string hexencode(byte[] toencode){ 
 stringbuilder sb=new stringbuilder(toencode.length*2); 
 for(byte b:toencode){ 
  sb.append(integer.tohexstring((b&0xf0)>>>4)); 
  sb.append(integer.tohexstring(b&0x0f));  
 } 
 return sb.tostring().touppercase(); 
 } 
} 

一步步来，接下来看bean类，就是每个圆点的属性
constants

package com.example.gesturelock; 
 
public class constants { 
 public static final int point_state_normal = 0; // 正常状态 
 public static final int point_state_selected = 1; // 按下状态 
 public static final int point_state_wrong = 2; // 错误状态 
 
}

接下来就看那9个点的绘制界面
