从Json对象中获取字符串值

Question

在我的应用程序中，我从HTTP Response获取以下的json。

[{"Date":"2012-1-4T00:00:00","keywords":null,"NeededString":"this is the sample string I am needed for my project","others":"not needed"}]

我想从上面的json中获得 "NeededString" ，如何实现呢？

Answer 1

String str="{"Date":"2012-1-4T00:00:00","keywords":null,"NeededString":"this is the sample string I am needed for my project","others":"not needed"}";

转义不写了，说下

JsonObject jobj=new JsonObject(str);
String needStr=jobj.getStrig("NeededString");
