我不断获取当前位置,现在我想每隔1到5秒将此连续位置发送到服务器。我该怎么做?
Android代码:
public class MainActivity extends Activity implements GoogleApiClient.ConnectionCallbacks,
GoogleApiClient.OnConnectionFailedListener, LocationListener {
TextView txtOutputLat, txtOutputLon;
Location mLastLocation;
private GoogleApiClient mGoogleApiClient;
private LocationRequest mLocationRequest;
String lat, lon;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
txtOutputLat = (TextView) findViewById(R.id.textView);
txtOutputLon = (TextView) findViewById(R.id.textView2);
buildGoogleApiClient();
}
@Override
public void onConnected(Bundle bundle) {
mLocationRequest = LocationRequest.create();
mLocationRequest.setPriority(LocationRequest.PRIORITY_HIGH_ACCURACY);
mLocationRequest.setInterval(100); // Update location every second
LocationServices.FusedLocationApi.requestLocationUpdates(mGoogleApiClient, mLocationRequest, this);
mLastLocation = LocationServices.FusedLocationApi.getLastLocation(
mGoogleApiClient);
if (mLastLocation != null) {
lat = String.valueOf(mLastLocation.getLatitude());
lon = String.valueOf(mLastLocation.getLongitude());
}
updateUI();
}
@Override
public void onConnectionSuspended(int i) {
}
@Override
public void onLocationChanged(Location location) {
lat = String.valueOf(location.getLatitude());
lon = String.valueOf(location.getLongitude());
updateUI();
}
@Override
public void onConnectionFailed(ConnectionResult connectionResult) {
buildGoogleApiClient();
}
synchronized void buildGoogleApiClient() {
mGoogleApiClient = new GoogleApiClient.Builder(this)
.addConnectionCallbacks(this)
.addOnConnectionFailedListener(this)
.addApi(LocationServices.API)
.build();
}
@Override
protected void onStart() {
super.onStart();
mGoogleApiClient.connect();
}
@Override
protected void onDestroy() {
super.onDestroy();
mGoogleApiClient.disconnect();
}
void updateUI() {
txtOutputLat.setText(lat);
txtOutputLon.setText(lon);
}
}
