\- 系统进程显示和隐藏  
  
  
\- 创建进程管理设置页面:ProcessManagerSettingActivity  
\- 编写设置页面布局文件  
\- 监听Checkbox的勾选事件,更新本地SharePreference  
  
  
// 根据本地记录,更新checkbox状态  
boolean showSystem = mPrefs.getBoolean("show\_system\_process", true);

\- 桌面Widget(窗口小部件)  
  
  
\- widget介绍(Android, 瑞星,早期word)  
\- widget谷歌文档查看(API Guide->App Components->App Widget)  
\- widget开发流程  
  
  
1. 在com.itheima.mobilesafe.receiver目录下创建MyWidget并且继承AppWidgetProvider  
2. 在功能清单文件注册，参照文档  
  
  
<receiver android:name=".receiver.MyWidget" >  
           <intent-filter>  
               <action android:name="android.appwidget.action.APPWIDGET\_UPDATE" />  
           </intent-filter>  
  
           <meta-data  
               android:name="android.appwidget.provider"  
               android:resource="@xml/appwidget\_info" />  
       </receiver>  
  
  
3. 在res/xml/创建文件example\_appwidget\_info.xml拷贝文档内容  
  
<appwidget-provider xmlns:android="http://schemas.android.com/apk/res/android"      
   android:minWidth="294dp"      
   android:minHeight="72dp"//能被调整的最小宽高，若大于minWidth minHeight 则忽略      
   android:updatePeriodMillis="86400000"//更新周期,毫秒,最短默认半小时      
   android:previewImage="@drawable/preview"//选择部件时 展示的图像,3.0以上使用,默认是ic\_launcher      
   android:initialLayout="@layout/example\_appwidget"//布局文件  
   android:configure="com.example.android.ExampleAppWidgetConfigure"//添加widget之前,先跳转到配置的activity进行相关参数配置,这个我们暂时用不到         
   android:resizeMode="horizontal|vertical"//widget可以被拉伸的方向。horizontal表示可以水平拉伸，vertical表示可以竖直拉伸  
android:widgetCategory="home\_screen|keyguard"//分别在屏幕主页和锁屏状态也能显示(4.2+系统才支持)  
    android:initialKeyguardLayout="@layout/example\_keyguard"//锁屏状态显示的样式(4.2+系统才支持)  
>  
</appwidget-provider>  
  
  
4. 精简example\_appwidget\_info.xml文件,最终结果:  
  
  
<appwidget-provider xmlns:android="http://schemas.android.com/apk/res/android"  
   android:minWidth="294dp"      
    android:minHeight="72dp"  
   android:updatePeriodMillis="1800000"  
   android:initialLayout="@layout/appwidget"  
  >  
</appwidget-provider>  
  
  
5. widget布局文件:appwidget.xml  
  
  
<?xml version="1.0" encoding="utf-8"?>  
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"  
   android:layout\_width="match\_parent"  
   android:layout\_height="match\_parent"  
   android:orientation="vertical" >  
  
   <TextView  
       android:id="@+id/textView1"  
       android:layout\_width="wrap\_content"  
       android:layout\_height="wrap\_content"  
       android:background="\#f00"  
       android:text="我是widget,哈哈哈"  
       android:textSize="30sp" />  
</LinearLayout>  
  
  
\- 简单演示,高低版本对比  
\- 仿照金山widget效果, apktool反编译,抄金山布局文件(业内抄袭成风)  
  
  
1. 反编译金山apk  
  
  
使用apktool,可以查看xml文件内容  
apktool d xxx.apk  
2. 在金山清单文件中查找 APPWIDGET\_UPDATE, 找到widget注册的代码  
3. 拷贝金山widget的布局文件process\_widget\_provider.xml到自己的项目中  
4. 从金山项目中拷贝相关资源文件,解决报错   
5. 运行,查看效果

\- 定时更新widget  
  
  
问题: 我们需要通过widget实时显示当前进程数和可用内存,但widget最短也得半个小时才会更新一次, 如何才能间隔比较短的时间来及时更新?  
  
查看金山日志:  
  
当桌面有金山widget时, 金山会在后台启动service:ProcessService,并定时输出如下日志:  
03-29 08:43:03.070: D/MoSecurity.ProcessService(275): updateWidget  
  
该日志在锁屏状态下也一直输出.  
  
  
解决办法: 后台启动service,UpdateWidgetService, 并在service中启动定时器来控制widget的更新

启动和销毁service的时机  
  
  
分析widget的声明周期,在onEnabled和onUpdate中启动服务, 在onDisabled中结束服务  
  
  
\- 注意: APK安装在sd卡上，widget在窗口小部件列表里无法显示。   android:installLocation="preferExternal", 修改过来后，需要卸载，再去安装widget才生效；

// 当点击widget布局时,跳转到主页面  
views.setOnClickPendingIntent(R.id.ll\_root, pendingIntent);

\- 动画实现  
  
  
\- 解决动画移动问题  
  
  
导致的原因，动画没有开始播放，界面就刷新了。  
动画播放需要时间的，动画没有播就变成了新的View对象。就播了新的View对象，  
让动画播放完后，再去更新页面；
