檢測GPS或者網絡是否可用

需要檢測GPS或者WiFi或者手機網絡是否可用，我當前的代碼可以檢測出GPS。但是檢測網絡時就報錯：

The method isProviderEnabled(String) in the type LocationManager is not applicable for the arguments (String, String)

代碼：

if (locationManager.isProviderEnabled(LocationManager.GPS_PROVIDER, LocationManager.NETWORK_PROVIDER)){
            Toast.makeText(this, "GPS is Enabled in your device", Toast.LENGTH_SHORT).show();
        }else{
            displayAlert();
        }

最佳回答：

你需要分開檢查

if (locationManager.isProviderEnabled(LocationManager.GPS_PROVIDER) ||
    locationManager.isProviderEnabled(LocationManager.NETWORK_PROVIDER)){
        Toast.makeText(this, "GPS/Network is Enabled in your device", 
            Toast.LENGTH_SHORT).show();
    }else{
        displayAlert();
    }
