其实一般的方法就可以获取到经纬度，网上这样的例子也很多

方法一：

@SuppressLint("MissingPermission")
private static Location getLastKnownLocation(Activity activity) {
    LocationManager mLocationManager = (LocationManager) activity.getApplicationContext().getSystemService(LOCATION_SERVICE);
    List<String> providers = mLocationManager.getProviders(true);
    Location bestLocation = null;
    for (String provider : providers) {
        Location l = mLocationManager.getLastKnownLocation(provider);
        if (l == null) {
            continue;
        }
        if (bestLocation == null || l.getAccuracy() < bestLocation.getAccuracy()) {
            bestLocation = l;
        }
    }
    return bestLocation;
}

但是在一些做过手脚的Android系统设备就是不行，于是：

方法二：

@SuppressLint("MissingPermission")
private static void getLastKnownLocation2(Activity activity) {
    LocationManager mLocationManager = (LocationManager) activity.getApplicationContext().getSystemService(LOCATION_SERVICE);
    mLocationManager.requestLocationUpdates(LocationManager.GPS_PROVIDER, 3000, 0, locationListener);
    mLocationManager.requestLocationUpdates(LocationManager.NETWORK_PROVIDER, 3000, 0, locationListener);
}

private static LocationListener locationListener = new LocationListener() {
    @Override
    public void onStatusChanged(String provider, int status, Bundle arg2) {
        Log.d("cyp", "onStatusChanged: ");
    }

    @Override
    public void onProviderEnabled(String provider) {
        Log.d("cyp", "onProviderEnabled: " + provider );
    }

    @Override
    public void onProviderDisabled(String provider) {
        Log.d("cyp", "onProviderDisabled: " + provider);
    }

    @Override
    public void onLocationChanged(Location location) {
        //如果位置发生变化,重新显示
        Log.d("cyp", "onLocationChanged:经度 "+location.getLongitude()+"纬度"+location.getLatitude());
        //这边就是获取到的经纬度，测试估计要4到5分钟才能获取得到，耐心点等等吧
     
    }
};
