我正在尝试请求对ACCESS_FINE_LOCATION的许可，并不断收到错误消息无法解析符号'MY_PERMISSIONS_REQUEST_ACCESS_FINE_LOCATION"，这是我的代码，有人知道问题出在哪里吗?

I am trying to request permission for ACCESS_FINE_LOCATION and keep getting the error 'Cannot Resolve Symbol 'MY_PERMISSIONS_REQUEST_ACCESS_FINE_LOCATION', here is my code, does anyone know what the issue is?

if (ContextCompat.checkSelfPermission(this, Manifest.permission.ACCESS_FINE_LOCATION)
                != PackageManager.PERMISSION_GRANTED) {
            if (ActivityCompat.shouldShowRequestPermissionRationale(this, Manifest.permission.ACCESS_FINE_LOCATION)){
                checkSelfPermission("Accept this to use location functionality");
            }
            else{
                ActivityCompat.requestPermissions(GpMap.this,
                        new String[]{Manifest.permission.ACCESS_FINE_LOCATION},
                        MY_PERMISSIONS_REQUEST_ACCESS_FINE_LOCATION);
            }

推荐答案

您尚未在此Java类中的任何地方将MY_PERMISSIONS_REQUEST_ACCESS_FINE_LOCATION定义为int值.

You have not defined MY_PERMISSIONS_REQUEST_ACCESS_FINE_LOCATION as an int value anywhere in this Java class.
