A sample of using convertPointToView

app.js

var win = Ti.UI.createWindow(
	{ backgroundColor: 'black' }
);
var center1 = {'x': 100, 'y':100}; 
var center2 = {'x': 100, 'y':250};
var lastIndex = 1;
var background = Ti.UI.createView({ backgroundColor:"#444444", });
var view = Ti.UI.createView({ backgroundColor:'red', center:center1, width:100, height:100, zIndex:lastIndex++, });
var view2 = Ti.UI.createView({ backgroundColor:'green', center:center2, width:100, height:100, zIndex:lastIndex, });
background.addEventListener('touchstart', function(e){
	var bgPoint = background.convertPointToView(e, background);
	Ti.API.debug("Background Point: " + bgPoint.x + "," + bgPoint.y);
	view.center = bgPoint;
	view.backgroundColor='blue';
});

view.addEventListener('touchend', function(e){
	view.center = center1;
	view.backgroundColor = 'red';
});
win.add(background); 
win.add(view); 
win.add(view2);
win.open();
