こんにちは私は5秒ごとに位置を取得しようとしています、速度と総距離または旅行を計算しますが、正確な距離と速度を与えていません。 TIA場所の距離と速度を取得する
public class LocationUpdater extends Service implements GoogleApiClient.ConnectionCallbacks,
GoogleApiClient.OnConnectionFailedListener{
private double latitude ;
private double longitude ;
Session session;
Context context;
LocationRequest mLocationRequest;
private static final int MILLISECONDS_PER_SECOND = 1000;
public static final int UPDATE_INTERVAL_IN_SECONDS = 5;
private static final long UPDATE_INTERVAL =
MILLISECONDS_PER_SECOND * UPDATE_INTERVAL_IN_SECONDS;
private static final int FASTEST_INTERVAL_IN_SECONDS = 10;
private static final long FASTEST_INTERVAL =
MILLISECONDS_PER_SECOND * FASTEST_INTERVAL_IN_SECONDS;
private static final int DESIRED_ACCURACY = 10;
private static final float SMALLEST_DISPLACEMENT = 10f;
/**
* Provides the entry point to Google Play services.
*/
protected GoogleApiClient mGoogleApiClient;
public LocationUpdater() {
}
@Override
public int onStartCommand(Intent intent, int flags, int startId) {
context = LocationUpdater.this;
session = Session.getSession(context);
buildGoogleApiClient();
mGoogleApiClient.connect();
return START_STICKY;
}
protected synchronized void buildGoogleApiClient() {
mGoogleApiClient = new GoogleApiClient.Builder(context)
.addConnectionCallbacks(this)
.addOnConnectionFailedListener(this)
.addApi(LocationServices.API).build();
}
@Override
public IBinder onBind(Intent intent) {
// TODO: Return the communication channel to the service.
throw new UnsupportedOperationException("Not yet implemented");
}
@Override
public void onConnected(Bundle bundle) {
try{
mLocationRequest = LocationRequest.create();
mLocationRequest.setPriority(LocationRequest.PRIORITY_HIGH_ACCURACY);
mLocationRequest.setSmallestDisplacement(SMALLEST_DISPLACEMENT);
requestLocationUpdate();
}catch (SecurityException ex){
ex.printStackTrace();
}
}
@Override
public void onConnectionSuspended(int i) {
}
@Override
public void onConnectionFailed(ConnectionResult connectionResult) {
mGoogleApiClient.connect();
}
@Override
public void onDestroy() {
super.onDestroy();
if(session.getTrip_status().equalsIgnoreCase(Utils.trip_status_started))
startService(new Intent(LocationUpdater.this,LocationUpdater.class));
}
は、私はすべての滑らかで正確ではない結果が、更新プログラムを取得していないことができています。それが正しい方法であるかどうか私に教えてください。そうでなければ何かを試してみるべきです。以下は
は私の場所のアップデータコードprivate void fetchMyLocation(){
try{
LocationServices.FusedLocationApi.requestLocationUpdates(mGoogleApiClient, mLocationRequest, new LocationListener() {
@Override
public void onLocationChanged(Location location) {
if (location != null) {
latitude = location.getLatitude();
longitude = location.getLongitude();
Log.wtf("ankit","accuracy "+location.getAccuracy());
if (location.hasAccuracy() && location.getAccuracy() <= DESIRED_ACCURACY) {
// This is your most accurate location.
Log.wtf("ankit","latitude:::"+latitude);
Log.wtf("ankit","longitude:::"+longitude);
session.setCurrentLatitude(""+latitude);
session.setCurrentLongitude(""+longitude);
if(session.getTrip_status().equalsIgnoreCase(Utils.trip_status_started)){
updateDistanceAndSpeed(latitude,longitude);
} else {
UpdateLocationListner.getInstance().changeState(latitude,longitude,"");
}
}
}
}
});
}catch (SecurityException ex){
ex.printStackTrace();
}
}
であり、これは私が速度と距離を計算する方法であるあなただけの緯度と
public void setLatLng(LatLng origins, LatLng destinations) {
url = "http://maps.googleapis.com/maps/api/distancematrix/json?" +
"origins=" + origins.latitude + "," + origins.longitude + "" +
"&destinations=" + destinations.latitude + "," + destinations.longitude + "" +
"&mode=driving" +
"&language=en-EN" +
"&sensor=false";
}
ハンドル経度を渡す必要が
// update speed and distance
private void updateDistanceAndSpeed(double latitude,double longitude){
long currentTimeMills = System.currentTimeMillis();
if (session.getLastLatitude().equalsIgnoreCase("")
&& session.getLastLongitude().equalsIgnoreCase("")) {
session.setLastLatitude(""+latitude);
session.setLastLongitude(""+longitude);
}else {
synchronized (this){
try{
String lat = ""+latitude;
String lng = ""+longitude;
double speed = 0;
if(!lat.equalsIgnoreCase(session.getLastLatitude())
&& !lng.equalsIgnoreCase(session.getLastLongitude())){
Location locationA = new Location("point A");
locationA.setLatitude(latitude);
locationA.setLongitude(longitude);
Location locationB = new Location("point B");
locationB.setLatitude(Double.parseDouble(session.getLastLatitude()));
locationB.setLongitude(Double.parseDouble(session.getLastLongitude()));
if(session.getDistance().equalsIgnoreCase(""))
session.setDistance("0");
Log.wtf("ankit","total distance:"+session.getDistance());
float lastDistance = Float.parseFloat(session.getDistance());
float distance[] = new float[1];
Location.distanceBetween(latitude, longitude,
Double.parseDouble(session.getLastLatitude()),
Double.parseDouble(session.getLastLongitude()), distance);
if(!session.getLastTimeStamp().equalsIgnoreCase("")){
long lastTime = Long.parseLong(session.getLastTimeStamp());
long timeDifference = currentTimeMills - lastTime;
long diffInSec = TimeUnit.MILLISECONDS.toSeconds(timeDifference);
speed = distance[0]/diffInSec;
} else {
speed = 0;
}
speed = speed*3.6;
speed = Utils.round(speed,2);
float roundDistance = Utils.round(distance[0],2);
Log.wtf("ankit","roundDistance"+roundDistance);
float final_distance = lastDistance+roundDistance;
UpdateLocationListner.getInstance().changeState(latitude,longitude,""+speed+"/"+final_distance);
session.setDistance(""+final_distance);
} else {
UpdateLocationListner.getInstance().changeState(latitude,longitude,"0/0");
}
// send speed
}catch (Exception ex){
ex.printStackTrace();
}
}
session.setLastLatitude(""+latitude);
session.setLastLongitude(""+longitude);
session.setLastTimeStamp(""+currentTimeMills);
}
}
を使用する速度のため、通常は（少なくとも、多くの要因に応じて、30秒程度）5秒以上の方法時間がかかります私は5秒ごとに位置修正を要求しようとしていないと思う。 –
あなたはコード全体を投稿して修正するように頼むべきではありません。それ。問題をローカライズし、デバッグを使用して、結果をログに出力するなど。 –
@ ZamronyP.Juhara ok 30秒に変換してから、質問と回答をテストして編集します。 – shankey
