Android判断服务是否运行及定位问题实例分析

本文实例讲述了Android判断服务是否运行及定位问题。分享给大家供大家参考。具体如下：

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 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。
