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();
}

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();
}
