Android定位获取当前经纬度

1.使用android提供的LocationManager管理类
2.使用GPS或者网络定位
3.只使用了Log打印出经纬度，没有在界面显示

public class MainActivity extends Activity {
    private LocationManager locationManager;
    private String locationProvider;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        //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 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
     Log.i("TAG","经度"+location.getLongitude()+"纬度"+location.getLatitude());
        }
        //监视地理位置变化
        locationManager.requestLocationUpdates(locationProvider, 1000, 1, locationListener);

    }


    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 如果位置改变，经纬度没有变，不会执行此函数 应该说经纬度发生变化执行此函数
            Log.i("TAG","经度"+location.getLongitude()+"纬度"+location.getLatitude());

        }
    };

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

}

在AndroidManifest.xml中加入所需权限

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

已知缺点：
1.定位速度慢，效果差
2.没有检查是否打开GPS
