안드로이드에서 1 분마다 움직이는 동안 다른 위도와 경도를 얻는 방법은 무엇입니까?

Question

지금 나는 움직이는 동안 1 분마다 다른 위도와 경도를 얻기 위해 GPS로 작업하고 있으며 배열 목록에 저장해야합니다. 나는 이것을 위해 쓰레드를 사용하고있다. 나는이 링크를 따라 갔다. 이동하면서 http://www.androidhive.info/2012/08/android-working-with-google-places-and-maps-tutorial/

이제 내 문제는 서로 다른 위도와 경도 포인트를 획득 할 수 수 없습니다 . 첫 번째 값은 배열에 20 번만 저장됩니다. 왜냐하면 나는 밟는 곳을 20 번 달리게해야한다. 그러나 나는 다른 점을 얻고 배열 목록에 저장하고 싶다. 나는 실수를 어디에서했는지 모른다. 어떤 몸이라도이 문제를 해결할 수 있습니까? 미리 감사드립니다.

이 내용을 적용하면 10 초마다 새로 고침되고 투표를 통해 답을 수락합니다.

Handler mHandler1 = new Handler(); 

    new Thread(new Runnable() { 
     @Override 
     public void run() { 
      // TODO Auto-generated method stub 
      while (true) { 
       try { 
        Thread.sleep(10000); 
        mHandler1.post(new Runnable() { 

         @Override 
         public void run() { 
          // TODO Auto-generated method stub 



          // creating GPS Class object 
         GPSTracker gps = new GPSTracker (Tracking .this); 

          // check if GPS location have some values 
          if (gps.canGetLocation()) { 

           double currentlat = gps.getLatitude(); 
           double currentlong = gps.getLongitude(); 



          } else { 
           // no current location 
           gps.showSettingsAlert(); 
          } 
         } 
        }); 
       } catch (Exception e) { 
        // TODO: handle exception 
       } 
      } 
     } 
    }).start(); 

Answer 2

위도를 수집하는 루프에 sleep(100)을 사용했습니다.
시간 단위는 마이크로 초입니다. (알고있는 한)
20 * 100 = 2000로 단지 2 초입니다. 그리고 나는 GPS가 그렇게 빨리 업데이트한다고 생각하지 않는다.
이것 좀보세요.

대신 동일한 루프를 사용할 수 있지만 이전 값과 다른 경우에만 값을 저장하십시오.

if(oldLat != curLat){ 
    //store curLat to array 
    //and make oldLat = curLat 
}
