try{
    JSONObject json = new JSONObject(jsonstr);
    JSONArray items = json.getJSONArray("earthquakes");

    for(int i =0; i<items.length(); i++){
        TextView t=new TextView(context);
        t.setText(items.getJSONObject(i).getString('eqid'));
        ParentLayout.addView(t);
    }
}catch(JSONException e){
    e.printStacktrace();
}

see my edited code in question..i dont have any error..but response is not displaying

as you have used Relative layout your textview will be overlapping on each other...Try Linear layout or add attributes like layoutToLeftOf or above or below and like that....

You have a single JSON object which contains a Single JSON array. So you first retrieve the array from the object and then you are able to loop over it to retrieve all the items. In below code I assume you have the destined TextView objects in an array.

try{
    JSONObject json = new JSONObject(jsonstr);
    JSONArray items = json.getJSONArray("earthquakes");

    for(int i =0; i<items.length(); i++){
        textViews[i].setText(items.getJSONObject(i).getString('eqid'));
    }
}catch(JSONException e){
    e.printStacktrace();
}

That would be a separate question. Questions should stay on topic.

@Roman In my answer I state that I assume that the destined TextView objects are in an array and can therefore be referenced like textViews[i] in the loop. If the textView variable does not reference a TextView array you will get this error. I assume you know yourself where to find the TextViews you want to put the data.
