GPS Android requestLocationUpdate

Question

Ich habe eine Klasse namens GPSSampleLocation

Es gibt eine Funktion zum Einschalten von GPS und zum Abrufen des Standorts auf der Grundlage dieser Funktion

hier gpsEnabled wird wahr sein, aber in meinem Telefon, wenn ich für gps das GPS-Symbol auf oben in meinem PHONE anfordern wird blinken ... aber es ist nicht blinken auch ... und ich bin nicht bekommen Daten

public void getGPSLocation() {
    LocationManager mlocManager = (LocationManager) GPSSampleLocation.this
            .getSystemService(Context.LOCATION_SERVICE);
    boolean gpsEnabled = mlocManager
            .isProviderEnabled(LocationManager.GPS_PROVIDER);
    if (!gpsEnabled) {
        String provider = Settings.Secure.getString(
                getContentResolver(),
                Settings.Secure.LOCATION_PROVIDERS_ALLOWED);
        if (!provider.contains("gps")) { // if gps is disabled
            final Intent poke = new Intent();
            poke.setClassName("com.android.settings",
                    "com.android.settings.widget.SettingsAppWidgetProvider");
            poke.addCategory(Intent.CATEGORY_ALTERNATIVE);
            poke.setData(Uri.parse("3"));
            sendBroadcast(poke);
        }
    }
    gpsEnabled = mlocManager
            .isProviderEnabled(LocationManager.GPS_PROVIDER);
    System.out.println("GPS ENALBLE" + gpsEnabled);
    if (gpsEnabled) {
        mlocManager.requestLocationUpdates(
                LocationManager.GPS_PROVIDER, 0, 0,
                GPSSampleLocation.this);
    }
}

Ich habe diese Genehmigungen auch genutzt:

<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION"/>
<uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION"/>
<uses-permission android:name="android.permission.INTERNET"/>

Im Folgenden wird mein Code zum Testen von RequestLocationUpdates und LocationManager und LocationListener dargestellt.

package com.test.locationmanager;

import android.app.Activity;
import android.content.Context;
import android.location.Location;
import android.location.LocationListener;
import android.location.LocationManager;
import android.location.LocationProvider;
import android.os.Bundle;
import android.widget.TextView;

public class LocationManagerStatus extends Activity {
    private LocationManager locationManager;
    private TextView textView;

    private final LocationListener gpsLocationListener = new LocationListener() {

        @Override
        public void onStatusChanged(String provider, int status, Bundle extras) {
            switch (status) {
            case LocationProvider.AVAILABLE:
                textView.setText(textView.getText().toString() + "GPS available again\n");
                break;
            case LocationProvider.OUT_OF_SERVICE:
                textView.setText(textView.getText().toString() + "GPS out of service\n");
                break;
            case LocationProvider.TEMPORARILY_UNAVAILABLE:
                textView.setText(textView.getText().toString() + "GPS temporarily unavailable\n");
                break;
            }
        }

        @Override
        public void onProviderEnabled(String provider) {
            textView.setText(textView.getText().toString() + "GPS Provider Enabled\n");
        }

        @Override
        public void onProviderDisabled(String provider) {
            textView.setText(textView.getText().toString() + "GPS Provider Disabled\n");
        }

        @Override
        public void onLocationChanged(Location location) {
            locationManager.removeUpdates(networkLocationListener);

            textView.setText(textView.getText().toString() + "New GPS location: "
                    + String.format("%9.6f", location.getLatitude()) + ", "
                    + String.format("%9.6f", location.getLongitude()) + "\n");

        }
    };

    private final LocationListener networkLocationListener = new LocationListener() {

        @Override
        public void onStatusChanged(String provider, int status, Bundle extras) {
            switch (status) {
            case LocationProvider.AVAILABLE:
                textView.setText(textView.getText().toString() + "Network location available again\n");
                break;
            case LocationProvider.OUT_OF_SERVICE:
                textView.setText(textView.getText().toString() + "Network location out of service\n");
                break;
            case LocationProvider.TEMPORARILY_UNAVAILABLE:
                textView.setText(textView.getText().toString() + "Network location temporarily unavailable\n");
                break;
            }
        }

        @Override
        public void onProviderEnabled(String provider) {
            textView.setText(textView.getText().toString() + "Network Provider Enabled\n");

        }

        @Override
        public void onProviderDisabled(String provider) {
            textView.setText(textView.getText().toString() + "Network Provider Disabled\n");
        }

        @Override
        public void onLocationChanged(Location location) {
            textView.setText(textView.getText().toString() + "New network location: "
                    + String.format("%9.6f", location.getLatitude()) + ", "
                    + String.format("%9.6f", location.getLongitude()) + "\n");

        }
    };

    /** Called when the activity is first created. */
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);

        textView = (TextView) findViewById(R.id.textview);
        locationManager = (LocationManager) getSystemService(Context.LOCATION_SERVICE);

    }

    @Override
    protected void onResume() {
        super.onResume();

        locationManager.requestLocationUpdates(LocationManager.NETWORK_PROVIDER, 5000, 0, networkLocationListener);
        locationManager.requestLocationUpdates(LocationManager.GPS_PROVIDER, 3000, 0, gpsLocationListener);
    }

    @Override
    protected void onPause() {
        super.onPause();

        locationManager.removeUpdates(networkLocationListener);
        locationManager.removeUpdates(gpsLocationListener);
    }
}
