json-從Json對象中獲取字符串值

從Json對象中獲取字符串值

在我的應用程序中，我從HTTP Response獲取以下的json。

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

我想從上面的json中獲得 "NeededString" ，如何實現呢？

最佳回答：

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"}";

轉義不寫了，說下

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