[TIMOB-19200] Android: implement 'noresults' event on ListView

[ashcoding]

Jira: https://jira.appcelerator.org/browse/TIMOB-19200

Test code for listview:

var win = Ti.UI.createWindow({backgroundColor: 'grey', fullscreen: true});
var search = Titanium.UI.createSearchBar({
 barColor:'#000', 
 showCancel:true,
 height:43,
 top:0,
});
search.addEventListener('cancel', function(){
    search.blur();
});
// for textSearch, use the change event to update the search value
// search.addEventListener('change', function(e){
//     listView.searchText = e.value;
// });
var listView = Ti.UI.createListView({searchView: search, caseInsensitiveSearch: true});
// for textSearch, add the search bar or text field as a header view
// var listView = Ti.UI.createListView({headerView: search, caseInsensitiveSearch: true});
var listSection = Ti.UI.createListSection();
var fruits = ['Papaya', 'Peach', 'Pear', 'Persimmon', 'Pineapple', 'Pluot', 'Pomegranate'];
var data = [];
for (var i = 0; i < fruits.length; i++) {
data.push({
    properties: {title: fruits[i], searchableText: fruits[i]}
});
}
listSection.setItems(data);
listView.addEventListener('noresults', function(e){
    alert("No results found!");
});
listView.sections = [listSection];
win.add(listView);
win.open();

Test code for tableview:

var win = Ti.UI.createWindow({
    backgroundColor: 'blue',
    fullscreen: false
});

// Use action bar search view
var search = Ti.UI.Android.createSearchView({
    hintText: "Table Search"
});

win.activity.onCreateOptionsMenu = function(e) {
    var menu = e.menu;
    var menuItem = menu.add({
        title: 'Table Search',
        actionView : search,
        icon: (Ti.Android.R.drawable.ic_menu_search ? Ti.Android.R.drawable.ic_menu_search : "my_search.png"),
        showAsAction: Ti.Android.SHOW_AS_ACTION_IF_ROOM | Ti.Android.SHOW_AS_ACTION_COLLAPSE_ACTION_VIEW
    });
};

var data = [];
data.push(Ti.UI.createTableViewRow({title:'Apple'}));
data.push(Ti.UI.createTableViewRow({title:'Banana'}));
data.push(Ti.UI.createTableViewRow({title:'Orange'}));
data.push(Ti.UI.createTableViewRow({title:'Raspberry'}));

var tableview = Titanium.UI.createTableView({
    data: data,
    search: search,
    searchAsChild: false
});

tableview.addEventListener('noresults', function(e){
    alert("No results found!");
});

win.add(tableview);
win.open();

Code reviewed and functionally tested. Looks good, just a minor comment

@hieupham007 addressed comments.

Hmm, why are you overwriting the commit? It's better to have multiple commits so we can track what is changed. Next time please don't overwrite the commit with new changes.

Will do.
