/** * 判断服务是否正在运行 * * @param context * @param className 判断的服务名字:包名+类名 * @return true在运行 false 不在运行 */ public static boolean isServiceRunning(Context context, String className) { boolean isRunning = false ; ActivityManager activityManager = (ActivityManager) context .getSystemService(Context.ACTIVITY_SERVICE); //获取所有的服务 List<ActivityManager.RunningServiceInfo> services= activityManager.getRunningServices(Integer.MAX_VALUE); if (services!= null &&services.size()> 0 ){ for (ActivityManager.RunningServiceInfo service : services){ if (className.equals(service.service.getClassName())){ isRunning= true ; break ; } } } return isRunning; } |
在android开发中,经常会使用locationManager.getLastKnownLocation()定时获取经纬度,在不同真机测试中有的可以获取有的不可以获取,为了解决不同手机的兼容下,请用如下代码

public static Location getLocation(LocationManager locationManager, LocationListener locationListener) { Location location= null ; location = locationManager.getLastKnownLocation(LocationManager.GPS_PROVIDER); locationManager.requestLocationUpdates(LocationManager.GPS_PROVIDER, 0 , 0 , locationListener); if (location== null ){ location = locationManager.getLastKnownLocation(LocationManager.NETWORK_PROVIDER); locationManager.requestLocationUpdates(LocationManager.NETWORK_PROVIDER, 0 , 0 , locationListener); } return location; } |
希望本文所述对大家的Android程序设计有所帮助。
