Use Gson.

First, you need POJO class that matches your data.

class MyUser
int id;
String name;



Then, convert your string to List of POJO class.

// This is your string.
String myJsonString = "["id":1,"name":"hamid","id":2,"name":"mohamad","id":3,"name":"ali","id":4,"name":"john","id":5,"name":"smith"]";

// Create new Gson object.
Gson gson = new Gson();

// Convert
List<MyUser> userList = gson.fromJson(myJsonString, new TypeToken<List<MyUser>>()
.getType());


Next, use it!

for (MyUser u : userList)
HASHMRM.put(u.id, u.name);



Remember: Instead of using the HASHMRM as variable name, I suggest you to use java conventional camel case name HashMRM.
