如何在MySQL數據庫中每10秒更新經度和緯度？

Question

我想從Android設備獲取經緯度並將其發送到MySQL數據庫。當任何一個註冊了當前的經緯度保存在database.but我想知道如何更新，每10 seconds.here保存的經度和緯度是我的代碼：

Answer 1

創建一個後臺服務類這樣

public class LocationBackGroundService extends Service implements LocationListener, 
     GoogleApiClient.ConnectionCallbacks, 
     GoogleApiClient.OnConnectionFailedListener { 

    private static final String TAG = "LocationBackGroundService"; 
    private static final long INTERVAL = 100; 
    private static final long FASTEST_INTERVAL = 100; 

    LocationRequest mLocationRequest; 
    GoogleApiClient mGoogleApiClient; 
    Location mCurrentLocation; 
    Context mCOntext; 

    public void LocationBackGroundService(Context mContext) { 
     this.mCOntext = mContext; 
    } 

    protected void createLocationRequest() { 
     mLocationRequest = new LocationRequest(); 
     mLocationRequest.setInterval(INTERVAL); 
     mLocationRequest.setFastestInterval(FASTEST_INTERVAL); 
     mLocationRequest.setPriority(LocationRequest.PRIORITY_HIGH_ACCURACY); 
    } 

    @Override 
    public void onStart(Intent intent, int startId) { 
     super.onStart(intent, startId); 
     mGoogleApiClient.connect(); 
    } 

    @Override 
    public void onCreate() { 
     super.onCreate(); 

     if (!isGooglePlayServicesAvailable()) { 
      // finish(); 
     } 
     createLocationRequest(); 
     mGoogleApiClient = new GoogleApiClient.Builder(this) 
       .addApi(LocationServices.API) 
       .addConnectionCallbacks(this) 
       .addOnConnectionFailedListener(this) 
       .build(); 

     if (mGoogleApiClient.isConnected()) { 
      startLocationUpdates(); 
     } 
    } 

    private boolean isGooglePlayServicesAvailable() { 
     int status = GooglePlayServicesUtil.isGooglePlayServicesAvailable(this); 
     if (ConnectionResult.SUCCESS == status) { 
      return true; 
     } else { 
      return false; 
     } 
    } 

    @Nullable 
    @Override 
    public IBinder onBind(Intent intent) { 
     return null; 
    } 

    @Override 
    public void onConnected(Bundle bundle) { 
     startLocationUpdates(); 
    } 


    protected void startLocationUpdates() { 
     PendingResult<Status> pendingResult = LocationServices.FusedLocationApi.requestLocationUpdates(
       mGoogleApiClient, mLocationRequest, this); 

     Log.d(TAG, "Location update started ..............: "); 
    } 

    @Override 
    public void onConnectionSuspended(int i) { 

     Toast.makeText(this, "OnConnection Suspended", Toast.LENGTH_SHORT).show(); 
    } 

    @Override 
    public void onConnectionFailed(ConnectionResult connectionResult) { 
     Toast.makeText(this, "OnConnection Failed", Toast.LENGTH_SHORT).show(); 
    } 

    @Override 
    public void onLocationChanged(Location location) { 

     if (null != mCurrentLocation) { 
      mCurrentLocation = location; 
      String lat = String.valueOf(mCurrentLocation.getLatitude()); 
      String lng = String.valueOf(mCurrentLocation.getLongitude()); 

     } 
    } 
} 

而且打電話的時候，活動開始這樣

startService(new Intent(this, yourBackgroundServiceName.class)); 

和menifest

<service android:name=".yourBackgroundServiceName"></service> 

和唐;噸忘記添加運行在陳述服務之前的時間許可

Answer 2

你必須使用線程爲此，隨着時間的推移了10秒鐘，每10秒你在線程代碼將運行

new Handler().postDelayed(new Runnable() { 
     @Override 
     public void run() { 
      // This method will be executed once the timer is over 
      // insert your data to db here 


      // close this activity 
      finish(); 
     } 
    }, TIME_OUT); 

並設置超時時間爲

private static int TIME_OUT = 10000; 

在這裏你去:)

Answer 3

將您的緯度保存到LocalDB，您可以使用Shared Preferences。

有關共享偏好更多的幫助，使用給定鏈路https://www.tutorialspoint.com/android/android_shared_preferences.htm

讓不同的類，並作出方法來保存您的緯度經度時後10秒過你。

謝謝！
