推荐答案

仅此错误，我们只能告诉您您的问题正在发生，原因是String上的parseInt而不是int. 要解决此问题，您有两种可能:

With just this error we can only tell you that your problem is happening because of a parseInt on a String that is not an int. To correct this you have two possibilities :

1. 添加try{}catch(NumberFormatException e){//show error}
2. 向parseInt声明您拥有适当的东西；)

1. add try{}catch(NumberFormatException e){//show error}
2. Assert that you have the proper things into parseInt ;)
