Android 4.2 状态栏添加图标

整理了一下最近用到的代码，添加状态栏图标，以后备用。

import android.app.StatusBarManager;//首先导入包

 

StatusBarManager  mStatusBar = (StatusBarManager)getSystemService(Context.STATUS_BAR_SERVICE);//获取StatusBarManager对象

 

mStatusBar.setIcon(xx, picId,0,yy);//设置状态栏图标

 // xx(String类型) 是在framework/../config.xml  定义的属性，具体看下文

//yy(String类型)是对这个图标的描述

mStatusBar.setIconVisibility(xx, true);//显示图标
