I am beginner in Android. In my Project, I am getting the Following json from the HTTP Response.

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

```

I want to get the "NeededString" from the above json. How to get it?
