In this final, third part of my three-part introductory series on Scala.js I’ll demonstrate a technique that can help you build single-page web applications with Scala.js. That is, the body of your HTML page will look like this:
In my first “Hello, world” Scala.js tutorial I showed how to get started with Scala.js, including some necessary setup/configuration work. That tutorial ended by showing how to get the string “Hello, world” displayed in a browser.
I am working on a way to rapidly mock up Android applications using Android Studio, i.e., to rapidly prototype Android applications on the fly, and little snippets of code help to make this happen. For instance, this snippet of code shows how to show a popup dialog to prompt a user to enter information into a text field:
As another quick Android example, this Java source code shows how to add a “click listener” (on click/tap event) to an Android
Android Button FAQ: How do I add a listener to a Button in Android?
To add a click (tap) listener to a button in Android, just get a reference to the button (typically using findViewById), then call the setOnClickListener method of the button, like this:
Here's a quick note for those of us that like to create prototypes during a requirements process using HTML. Whenever you want to create a button that is supposed to simulate the action of moving to another screen, you can use code similar to the following code snippet to simulate this behavior:
