设置每个GPS定位之间的间隔

Question

我试图在Android中的每个GPS定位之间设置一个5分钟的间隔。我的代码如下所示：

private void startMonitoring() { 
    locationManager = (LocationManager) getSystemService(Context.LOCATION_SERVICE); 
    locationListener = new LocListener(); 
    if (locationManager.isProviderEnabled(locationManager.GPS_PROVIDER)){ 
     startUpdates(); 
    } else { 
     // I open here the preferences to force the user start the GPS 
    } 
} 

private void startUpdates(){ 
    locationManager.requestLocationUpdates(LocationManager.GPS_PROVIDER, 0, 0, locationListener); 
} 

public class LocListener implements LocationListener{ 
    @Override 
    public void onLocationChanged(Location loc){ 
    ... 
      locationManager.removeUpdates(locationListener); 
      scheduleUpdates(); 
    } 
    ... 
} 

private void scheduleUpdates(){ 
     // Wait 5 minutes 
     handler.sleep(5 * 60 * 1000); 
     startUpdates(); 
} 

class WaitHandler extends Handler { 
     @Override 
     public void handleMessage(Message message) {} 

     public void sleep (long delayMillis){ 
      this.removeMessages(0); 
      sendMessageDelayed(obtainMessage(0), delayMillis); 
     } 
    } 

我一直在这几个小时，但我一直没能找到一个好的解决办法呢。任何帮助，将不胜感激，

非常感谢你，

Answer 1

定义定时器T和处理程序处理，并写：

t = new Timer(); 
     t.schedule(new TimerTask(){public void run(){handler.post(new Runnable(){public void run(){ 
     //your code here 
}});}}, int delay, int rep); 

延迟是第一次运行前的毫秒数，并且每次运行都会通过代表毫秒（在您的情况中，rep = 1000 * 60 * 5）分离。

也许你应该使用requestLocationUpdate参数： locationManager.requestLocationUpdates(LocationManager.GPS_PROVIDER, 5*60*1000, 0, locationListener);
