How to create a floating help layout?

问题

I've got a {N} page and conditionally I'd like to create a floating bubble text label pointing to certain features on the page. e.g. "Press START button to blah".

Any help on how this could be done.

Preferably w/o modifying the xml page files.

I released a plugin that can do what you are requesting simply install it tns plugin add nativescript-tooltip then you can use it as follows

TypeScript

import * as frame from "ui/frame";
import {ToolTip} from "nativescript-tooltip";
new ToolTip(frame.topmost().getViewById("someView"),{text:"Some Text"});

JavaScript

const frame = require("ui/frame");
const ToolTip = require("nativescript-tooltip").ToolTip;
new ToolTip(frame.topmost().getViewById("someView"),{text:"Some Text"});
