如何使用安卓来获取经纬度

1.权限申请

package com.qin.longitude;

import android.Manifest;
import android.content.Context;
import android.content.pm.PackageManager;
import android.location.Location;
import android.location.LocationListener;
import android.location.LocationManager;
import android.os.Build;
import android.os.Bundle;
import android.util.Log;
import android.widget.Toast;

import androidx.annotation.RequiresApi;
import androidx.appcompat.app.AppCompatActivity;

public class MainActivity extends AppCompatActivity {

    @RequiresApi(api = Build.VERSION_CODES.M)
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        // Get user location
        LocationManager locationManager = (LocationManager) getSystemService(Context.LOCATION_SERVICE);

        // Keep track of user location.
        // Use callback/listener since requesting immediately may return null location.
        // IMPORTANT: TO GET GPS TO WORK, MAKE SURE THE LOCATION SERVICES ON YOUR PHONE ARE ON.
        // FOR ME, THIS WAS LOCATED IN SETTINGS > LOCATION.
        if (checkSelfPermission(Manifest.permission.ACCESS_FINE_LOCATION) != PackageManager.PERMISSION_GRANTED && checkSelfPermission(Manifest.permission.ACCESS_COARSE_LOCATION) != PackageManager.PERMISSION_GRANTED) {
            // TODO: Consider calling
            //    Activity#requestPermissions
            // here to request the missing permissions, and then overriding
            //   public void onRequestPermissionsResult(int requestCode, String[] permissions,
            //                                          int[] grantResults)
            // to handle the case where the user grants the permission. See the documentation
            // for Activity#requestPermissions for more details.
            return;
        }
        locationManager.requestLocationUpdates(LocationManager.NETWORK_PROVIDER, 1000, 10, new Listener());
        // Have another for GPS provider just in case.
        locationManager.requestLocationUpdates(LocationManager.GPS_PROVIDER, 1000, 10, new Listener());
        // Try to request the location immediately
        Location location = locationManager.getLastKnownLocation(LocationManager.NETWORK_PROVIDER);
        if (location == null){
            location = locationManager.getLastKnownLocation(LocationManager.GPS_PROVIDER);
        }
        if (location != null){
            handleLatLng(location.getLatitude(), location.getLongitude());
        }
        Toast.makeText(getApplicationContext(),
                "Trying to obtain GPS coordinates. Make sure you have location services on.",
                Toast.LENGTH_SHORT).show();
    }

    /**
     * Handle lat lng.
     */
    private void handleLatLng(double latitude, double longitude){
        Log.v("TAG", "-----------(" + latitude + "," + longitude + ")");
    }

    /**
     * Listener for changing gps coords.
     */
    private class Listener implements LocationListener {
        public void onLocationChanged(Location location) {
            double longitude = location.getLongitude();
            double latitude = location.getLatitude();
            handleLatLng(latitude, longitude);
        }

        public void onProviderDisabled(String provider){}
        public void onProviderEnabled(String provider){}
        public void onStatusChanged(String provider, int status, Bundle extras){}
    }
}

注意我这里没有写动态申请地理权限的代码，要自己在设置里给应用分配gps权限先，如果有需要，可以用easypermision自行添加动态申请的代码
