how to display arraylist items in toast?

Question

I am using json parsing,i am sending five emails and five names and in response it gives

{
    "invitefriend": [
        {

            "message": "Friend Request sent to : abc"
        },
        {

            "message": "Friend Request sent to : def"
        }
    ]
}

now what i am trying is i want to get abc and def in toast,but it gives one by one seperatly

 JSONArray jsonary=json.getJSONArray("invitefriend");

            for (int i = 0; i < jsonary.length(); i++) {
                JSONObject c = jsonary.getJSONObject(i);
                // creating new HashMap
                HashMap<String, String> map = new HashMap<String, String>();
                // adding each child node to HashMap key => value
                // map.put(INTERESTACCEPT_USER_ID, c.getString(INTERESTACCEPT_USER_ID));
                map.put(TAG_SUCCESS_INVITE,c.getString(TAG_SUCCESS_INVITE));
                map.put(TAG_SUCCESS_MESSAGE, c.getString(TAG_SUCCESS_MESSAGE));

                ArrayList<String> msgs=new ArrayList<String>();
                msgs=map.put(TAG_SUCCESS_MESSAGE, c.getString(TAG_SUCCESS_MESSAGE));
                System.out.println("MESSAGE : " + msg);

                // adding HashList to ArrayList

               getActivity().runOnUiThread(new Runnable() {
                    @Override
                    public void run() {
                        Toast.makeText(getActivity(),""+msgs, Toast.LENGTH_LONG).show();
                    }
                });
                data.add(map);
            }

Try this,

   JSONArray jsonary=json.getJSONArray("invitefriend");
    ArrayList<String> msgs;
            for (int i = 0; i < jsonary.length(); i++) {
                JSONObject c = jsonary.getJSONObject(i);
                // creating new HashMap
                HashMap<String, String> map = new HashMap<String, String>();
                // adding each child node to HashMap key => value
                // map.put(INTERESTACCEPT_USER_ID, c.getString(INTERESTACCEPT_USER_ID));
                map.put(TAG_SUCCESS_INVITE,c.getString(TAG_SUCCESS_INVITE));
                map.put(TAG_SUCCESS_MESSAGE, c.getString(TAG_SUCCESS_MESSAGE));

                msgs = new ArrayList<String>(map.values());

                System.out.println("MESSAGE : " + msgs);

                // adding HashList to ArrayList


                data.add(map);
            }
           getActivity().runOnUiThread(new Runnable() {
                    @Override
                    public void run() {
                         Toast.makeText(getActivity(),msgs,Toast.LENGTH_LONG).show();
                    }
                });

You're getting multiple Toast s because you're Toast ing inside the for loop. Simply move that call to outside the loop:

JSONArray jsonary=json.getJSONArray("invitefriend");
ArrayList<String> msgs=new ArrayList<String>();
String msg = null;

for (int i = 0; i < jsonary.length(); i++) {
    JSONObject c = jsonary.getJSONObject(i);
    // creating new HashMap
    HashMap<String, String> map = new HashMap<String, String>();
    // adding each child node to HashMap key => value
    // map.put(INTERESTACCEPT_USER_ID, c.getString(INTERESTACCEPT_USER_ID));
    map.put(TAG_SUCCESS_INVITE,c.getString(TAG_SUCCESS_INVITE));
    map.put(TAG_SUCCESS_MESSAGE, c.getString(TAG_SUCCESS_MESSAGE));

    msg=map.put(TAG_SUCCESS_MESSAGE, c.getString(TAG_SUCCESS_MESSAGE));
    msgs.add(msg);
    System.out.println("MESSAGE : " + msg);

    // adding HashList to ArrayList
    data.add(map);
}

getActivity().runOnUiThread(new Runnable() {
        @Override
        public void run() {
            Toast.makeText(getActivity(), msgs.toString(), Toast.LENGTH_LONG).show();
        }
    });

Also, we've defined the ArrayList msgs to collect the response messages, which we Toast directly with msgs.toString() .

You have to do ""+array list Then it will display all array list items in toast. Or if you need all one by one,then take a for loop with length of array list in that u just add array list[i]like

for (int i=0;i<=arraylist.length;i++){

        Toast.makeText(getContext(),arraylist[i],Toast.LENGTH_SHORT).show();
    }

Try like this. i think its helpfull

featured_list = new ArrayList<Featured>();
for (int i = 0; i < jarray.length(); i++) {
JSONObject object = jarray.getJSONObject(i);
Toast.makeText(getApplicationContext(), object.getString("thumb").toString(), Toast.LENGTH_LONG).show();
 }
