How to send json response data to a custom ListView? is the JSON response is dictionary?

Question

My Activity:

public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    mediator_id= getIntent().getStringExtra("mediator_id");
    mediator_name= getIntent().getStringExtra("mediator_name");
    new Thread(transaction).start();
    setContentView(R.layout.transaction_log);

    ImageView back=(ImageView) findViewById(R.id.imageView1);
    back.setOnClickListener(new OnClickListener() {

        @Override
        public void onClick(View v) {

            startActivity(new Intent(Log.this,Mediator.class));

        }
    });
}

public Runnable transaction = new Runnable() {
    public void run() {

        try {
            if (mediator_id.equals("") || mediator_name.equals("")) {
                runOnUiThread(new Runnable() {
                    @Override

                json.put("no", mediator_id);

I've got a JSON response like this:

D/Result(3928): {"19":{"sender_id":"1210","m":"200","mediator":"121030910807","reciever":"508505","id":"21","sender_no":"508505","remarks":"NULL","sender_no":"12","type":"books","date_time":"2014-08-22 19:45:06"},"22":{"sender_id":"121030910805","m":"50.0","mediator":"121030910807","reciever":"508505","id":"24","sender_no":"508505","remarks":"NULL","sender_no":"121030910805","type":"books","date_time":"2014-08-23 11:22:17"},"17":

How can I send this data to ListView?

        LayoutInflater inflater = ((Activity) context).getLayoutInflater();
        RelativeLayout.LayoutParams lp = new RelativeLayout.LayoutParams(parent.getLayoutParams());

        for (int j = 0; j < myImage.getName().length; j++) {

            row = inflater.inflate(layoutResourceId, parent, false);

            RelativeLayout linearMain = (RelativeLayout) row
                    .findViewById(R.id.relMain);
            TextView transaction_date = (TextView) row.findViewById(R.id.transaction_date);
            //transaction_date.setText(myImage.name[j]);

            TextView transaction_type = (TextView) row.findViewById(R.id.transaction_type);
            //transaction_type.setText(myImage.name[j]);

            TextView aadhar_number = (TextView) row.findViewById(R.id.number);

Can you please tell me how can I send the JSON response to the ListView

Google [JSON Parsing in Android](https://www.google.co.in/?gfe_rd=cr&ei=osD6U4GZNJSAoAOklIKQBg&gws_rd=ssl#q=json%20parsing%20in%20android%20tutorial). Basically you need to create a DAO class. In your case you are passing arraylist of Item, so create a class called Item and put getters and setters for the details in your JSON response. Parse the response, store that data in object of Item class, and add those objects to your arraylist. Finally pass that arraylist to adapter of your listview and override `getView` — Nitish, Aug 25 '14 at 04:56

Try http://jsongen.byingtondesign.com/ link. It will parse JSON to create client side source files to model the JSON data structure. Then use Gson to parse the response thats simpler
