这里我在代码

中得到了一个Exception

String[] r2=retArray[1].split(" ");     

System.out.println("Outside");
 return Float.valueOf(retArray[0]);

任何人都可以解决此问题。 在此先感谢。

Answer 1

可能你的电话有例外。你正在捕捉它，但随后无所事事。执行System.out.println（结果）并查看HTTP调用的结果。

Answer 2

您不会提供例外目录，因此解决此问题的复杂性

可能有助于像这样更改此代码

String[] r2=retArray[1].split(" ");     

System.out.println("Outside");
 return Float.valueOf(retArray[1]);
