feat(android): new widget: Ti.UI.Android.RadioButtons

[m1ga]

Currently we don't have native RadioButtons! This PR will add a new widget Ti.UI.Android.createRadioButtons().

Properties:

• labels: Array of strings
• selectedIndex
• color
• tintColor

Events:

• click: returns index

var win = Ti.UI.createWindow({});
var radioButtons = Ti.UI.Android.createRadioButtons({
	labels: ["option 1", "option 2", "option 3"],
	top: 10,
	left: 10,
	selectedIndex: 1
})
var btn = Ti.UI.createButton({
	title: "select item 2",
	bottom: 10
});
var btn2 = Ti.UI.createButton({
	title: "change labels",
	bottom: 60
});
var btn3 = Ti.UI.createButton({
	title: "change color",
	bottom: 110
});
btn.addEventListener("click", function(){
	radioButtons.selectedIndex = 1;
	console.log(radioButtons.selectedIndex)
})
btn2.addEventListener("click", function(){
	radioButtons.labels = ["new option 1", "new option 2", "new option 3", "new option 4"];
})
btn3.addEventListener("click", function(){
	radioButtons.color = "yellow";
	radioButtons.tintColor = "yellow"
})
radioButtons.addEventListener("click", function(e){
	alert("Item " + e.index + " was clicked. Value: " + radioButtons.labels[e.index]);
	console.log("Index: " + radioButtons.selectedIndex);
})
console.log(radioButtons.selectedIndex);

win.add([radioButtons, btn, btn2, btn3]);
win.open();

Todo:

• add it to Alloy [separate PR afterwards]

is there something like this on iOS? Otherwise I'll move it to the Android namespace
I don't think so, afaik iOS never supported RadioButtons(only macOS does), so every app that has it they created/emulated from scratch using Button/Image/etc
I checked guidelines recently and instead of RadioButton we should use Switch

Ah, good to know. I'll move it to the Android namespace.

Update:

• moved it into Ti.UI.Android
• added apidocs
• added color and tintColor
