var tableView = Titanium.UI.createTableView({
    top : 21,
    left : 0,
    right : 0,
    seperatorColor : 'red'

var search = Titanium.UI.createSearchBar();
tableView.search = search;
 
var XHR = require("xhr");
var settingsTableData = [];
 
Ti.App.Properties.setString('f_l', null);
 
new XHR().get('<URL>', function(result) {
 
 
 
    var js_data = JSON.parse(result.data);
 
    var animals = js_data.animals;
 
    for (var p in animals) {
 
 
 
        var viewOne = Ti.UI.createView({

        var headerLabel = Ti.UI.createLabel({
