首先,您粘贴的代码范围是著名的,它是最后已知的网络位置和GPS提供商的组合。偶数 getLastKnownLocation 方法在之后调用 requestLocationUpdates 方法,此用法不完全可信。因为这些传感器不会以同步的方式给出结果。

你有两个选择,一个是打电话 GetLastKnown位置 为GPS获取最后一次获得的位置,第二次是用 . 选择这个,将取决于您的方案。

使用这个简短的代码只需GPS就可以得到经度和经度

LocationManager manager = (LocationManager) getSystemService(LOCATION_SERVICE);
            if (ActivityCompat.checkSelfPermission(this, Manifest.permission.ACCESS_FINE_LOCATION) != PackageManager.PERMISSION_GRANTED && ActivityCompat.checkSelfPermission(this, Manifest.permission.ACCESS_COARSE_LOCATION) != PackageManager.PERMISSION_GRANTED) {
                return;
            }
            Location location = manager.getLastKnownLocation(LocationManager.GPS_PROVIDER);
            Log.d("Location = ","Longitude "+location.getLongitude()+",Latitude "+location.getLatitude());
