本文讲的是通过安卓自带的LocationManager来获得现在定位的位置的经纬度值

private TextView tvResult;
    private Button btnTest;
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);

        btnTest = (Button) findViewById(R.id.btn_test);
        tvResult = (TextView) findViewById(R.id.tv_result);
        setContentView(R.layout.activity_main);
        btnTest.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View view) {
                getLocation();
            }
        });
     }

布局页的代码就不贴了就一个按钮，一个文本

下面就是获取坐标的重要部分了

public void getLocation() {
        //获取地理位置管理器
        locationManager = (LocationManager) getSystemService(Context.LOCATION_SERVICE);
        //获取所有可用的位置提供器
        List<String> providers = locationManager.getProviders(true);
        if (providers.contains(LocationManager.GPS_PROVIDER)) {
            //如果是GPS
            locationProvider = LocationManager.GPS_PROVIDER;
        } else if (providers.contains(LocationManager.NETWORK_PROVIDER)) {
            //如果是Network
            locationProvider = LocationManager.NETWORK_PROVIDER;
        } else {
            Toast.makeText(this, "没有可用的位置提供器", Toast.LENGTH_SHORT).show();
            return;
        }
        //获取Location
        Location location = locationManager.getLastKnownLocation(locationProvider);
        if (location != null) {
            //不为空,显示地理位置经纬度
            showLocation(location);
        }
        //监视地理位置变化
        locationManager.requestLocationUpdates(locationProvider, 3000, 1, locationListener);

    }

//显示坐标
    private void showLocation(Location location) {
        String locationStr = "维度：" + location.getLatitude() + "\n"
                + "经度：" + location.getLongitude();
        tvResult.setText(locationStr);
    }

/**
     * LocationListern监听器
     * 参数：地理位置提供器、监听位置变化的时间间隔、位置变化的距离间隔、LocationListener监听器
     */

    LocationListener locationListener = new LocationListener() {

        @Override
        public void onStatusChanged(String provider, int status, Bundle arg2) {

        }

        @Override
        public void onProviderEnabled(String provider) {

        }

        @Override
        public void onProviderDisabled(String provider) {

        }

        @Override
        public void onLocationChanged(Location location) {
            //如果位置发生变化,重新显示
            showLocation(location);

        }
    };

@Override
    protected void onDestroy() {
        super.onDestroy();
        if (locationManager != null) {
            //移除监听器
            locationManager.removeUpdates(locationListener);
        }
    }
