You can try this, JSONObject.put() uses a key value pair so do as needed:

try {
    JSONObject object = new JSONObject();
    object.put("username", "rajesh");
    object.put("password", "password");
} catch (JSONException e) {
    e.printStackTrace();
}

After forming the required JSONObject you can use HttpClient to send it onto a request, refer here.

You can also refer to my project on making Http requests on android here.

Yes, You can use by Json Object Like below,

JSONObject jsonObj = new JSONObject();
jsonObj.put("UserName", "Rajesh"); 
jsonObj.put("Password", "abc");
jsonObj.put("UserType", "member");

If you send In webservice then

String json = jsonObj.toString();

StringEntity se = new StringEntity(json);
httpPost.setEntity(se);
httpPost.setHeader("Accept", "application/json");
httpPost.setHeader("Content-type", "application/json");
HttpResponse httpResponse = httpclient.execute(httpPost);

also check pass json object in url

package com.aven.qqdemo;

import org.json.JSONException;
import org.json.JSONObject;

public class JsonUutis {

private void toWebService(){
    JSONObject json = new JSONObject();
    String username = "Rajesh";
    String password = "abc";
    String usertype = "member";
    putJson(json,"UserName", username);
    putJson(json,"Password", password);
    putJson(json,"UserType", usertype);
    String jsonString = json.toString();
    //Send jsonString to web service.
}

private void putJson(JSONObject json, String key, String value){
    try {
        json.put(key, value);
    } catch (JSONException e) {
        //Error happened.
    }
