我想toget位置仅使用GPS。我天玑想使用互联网和GPRS在这个应用程序。所以告诉我只用GPS提供商如何能得到位置。 我的code是贝洛奥里藏特。告诉我哪里错了这个。

code。

 包com.getlocation;

进口android.app.Activity;
进口android.content.Context;
进口android.location.Criteria;
进口android.location.Location;
进口android.location.LocationListener;

解决方案

使用此仅用于GPS提供商，它并不需要G​​PRS。

  locationManager.requestLocationUpdates（LocationManager.GPS_PROVIDER，0，0，mlocListener）;

＆LT;使用-权限的Andr​​oid：名称=android.permission.ACCESS_FINE_LOCATION＆GT;＆LT; /使用-许可＆GT;
 

您需要把权限清单文件。

i want toget location using GPS only. i dnt want to use internet and GPRS in this application. so tell me how can i get location using only GPS provider. my code is belo. tell me where m wrong in this.

code.

package com.getlocation;

import android.app.Activity;
import android.content.Context;
import android.location.Criteria;
import android.location.Location;
import android.location.LocationListener;
import android.location.LocationManager;
import android.os.Bundle;
import android.util.Log;
import android.widget.Toast;

public class UseGps extends Activity {
    /** Called when the activity is first created. */
    private String provider;
    LocationManager locationManager;
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main); /*
                                         * Use the LocationManager class to
                                         * obtain GPS locations
                                         */
        locationManager = (LocationManager) getSystemService(Context.LOCATION_SERVICE);
        LocationListener mlocListener = new MyLocationListener();
         Criteria criteria = new Criteria();
            criteria.setAccuracy(Criteria.ACCURACY_COARSE);
            criteria.setAccuracy(Criteria.ACCURACY_FINE);
            provider = locationManager.getBestProvider(criteria, true);
            locationManager.requestLocationUpdates(provider, 61000, 250,
                mlocListener);
    } /* Class My Location Listener */
public class MyLocationListener implements LocationListener {
    @Override
    public void onLocationChanged(Location loc) {
        loc.getLatitude();
        loc.getLongitude();
        String Text = "My current location is: " + "Latitude = "
                + loc.getLatitude() + "Longitude = " + loc.getLongitude();
        Toast.makeText(getApplicationContext(), Text, Toast.LENGTH_SHORT)
                .show();
        Log.d("TAG", "Starting..");
    }

    @Override
    public void onProviderDisabled(String provider) {
        Toast.makeText(getApplicationContext(), "Gps Disabled",
                Toast.LENGTH_SHORT).show();
    }

    @Override
    public void onProviderEnabled(String provider) {
        Toast.makeText(getApplicationContext(), "Gps Enabled",
                Toast.LENGTH_SHORT).show();
    }

    @Override
    public void onStatusChanged(String provider, int status, Bundle extras) {
    }
}/* End of Class MyLocationListener */
}/* End of UseGps Activity */

Use this for only GPS Provider, it does not need GPRS.

locationManager.requestLocationUpdates(LocationManager.GPS_PROVIDER, 0, 0, mlocListener);

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

You need to put the permission in manifest file.
