系统内部状态信息的相关api： 得到ActivityManager ： ActivityManager activityManager = (ActivityManager)this.getSystemService(ACTIVITY_SERVICE...isTopActivy(String cmdName){ ActivityManager manager = (ActivityManager) context.getSystemService(ACTIVITY_SERVICE...return names; } android 取当前显示的activity ： ActivityManager am = (ActivityManager) getSystemService(ACTIVITY_SERVICE
系统内部状态信息的相关api： 得到ActivityManager ： ActivityManager activityManager = (ActivityManager)this.getSystemService(ACTIVITY_SERVICE...isTopActivy(String cmdName){ ActivityManager manager = (ActivityManager) context.getSystemService(ACTIVITY_SERVICE...names; } android 取当前显示的activity是什么 ActivityManager am = (ActivityManager) getSystemService(ACTIVITY_SERVICE
而本文将介绍android设备中已启动的服务,并推断某一服务是启动 1.依据ACTIVITY_SERVICE获取系统服务 activityManager = (ActivityManager) getSystemService...(ACTIVITY_SERVICE); 2.获取系统中正在执行的服务 runningList = activityManager.getRunningServices(30);//代表我们希望返回的服务数目大小...displaySb.append(defaultStr).append("\n"); activityManager = (ActivityManager) getSystemService(ACTIVITY_SERVICE
isServiceRunning(String ServicePackageName) { ActivityManager manager = (ActivityManager) getSystemService(ACTIVITY_SERVICE
className)) return false; ActivityManager am = (ActivityManager) context.getSystemService(ACTIVITY_SERVICE
通过ActivityManager ActivityManager manager = (ActivityManager)context.getSystemService(ACTIVITY_SERVICE
ActivityManager am = (ActivityManager) getSystemService(ACTIVITY_SERVICE); ComponentName cn = am.getRunningTasks
1.代码获取当前app内存的使用情况 ActivityManager activityManager = (ActivityManager) getSystemService(ACTIVITY_SERVICE
通知栏，对话框，Toast是我们接触的三个提示框，通知栏是在系统的应用com.adnroid.systemui当中的 接触的几个Manger，getSystemService()方法得到的，参数： ACTIVITY_SERVICE
******************************************/ ActivityManager am = (ActivityManager) getSystemService(ACTIVITY_SERVICE
返回的对象 说明 WINDOW_SERVICE WindowManager 管理打开的窗口程序 LAYOUT_INFLATER_SERVICE LayoutInflater 取得xml里定义的view ACTIVITY_SERVICE
= null) { ActivityManager am = (ActivityManager) getSystemService(ACTIVITY_SERVICE);
网上搜到的方法大多数都是使用下面的代码： ActivityManager am = (ActivityManager) this.getSystemService(ACTIVITY_SERVICE);
(Context context){ ActivityManager activityManager = (ActivityManager) context.getSystemService(ACTIVITY_SERVICE
要查看具体应用系统分配的内存大小,还是需要实际去测试的, 测试方法如下: 方式一: ActivityManager activityManager = (ActivityManager) getSystemService(ACTIVITY_SERVICE
intentBatteryUsage); 16、获取进程号 ActivityManager mActivityManager = (ActivityManager) this.getSystemService(ACTIVITY_SERVICE
ActivityManager manager = (ActivityManager) getApplicationContext().getSystemService(ACTIVITY_SERVICE
while(true){ ActivityManager manager = (ActivityManager) getSystemService(ACTIVITY_SERVICE
