Custom Toast


Toasts are the preferred Android mechanism to deliver short messages to users. But, they tend to be kind of boring. So, why not make them more exciting? Let’s build a custom toast and make it pop!

Custom Toast

Custom Layout

First thing we’ll need is a custom layout for amazing toast. Let’s start off with something simple, a TextView and an ImageView:

Custom Toast

Awesome, we’ve defined our Toast’s layout. Time to use it.

First thing we’ll need to do is inflate it and initialize its views:

Next, we’ll create a new toast and add our custom view to it:

We can customize it even further: to make things interesting, we can also define the Toast’s gravity – to control where it appears on the screen:


And we’re done, simple as that! This is what the final thing looks like:

And just call it with:

Creating a Compound View in Android


Often, when developing Android applications, groups of views tend to be used in multiple places. In order to make things easier, it is considered good practice to encapsulate them in a custom compound view. This allows the same custom view component to be reused throughout the app.

A compound view or compound component is just a view composed of a group of views. This tutorial focuses on building a very basic compound view and defining some methods that change its state.

Creating the Compound View

Creating a Compound View is, in some respects, somewhat similar to creating a new Activity. A new class is created which contains all the view’s children and some methods to manipulate them.

To get started, we’ll first create a new XML layout file in /res/layout/view_article.xml. This will contain the compound view’s children:

Next, we need a class to inflate our new Article View. For simplicity’s sake, we’ll extend a basic RelativeLayout and define our child components. When the view is added to an Activity, it will basically act as a RelativeLayout and allow developers to customize it accordingly.

It is considered best practice to handle the instantiation of our UI components in the onFinishInflate() method in order to prevent any NullPointerExceptions, especially when using ImageViews with large Bitmaps.

At this point, our new Article View doesn’t really do anything special except displaying its children components. As a result, we’ll add some custom methods to manipulate its states:


Now that the ArticleView is complete, we just need to add it to an Activity. We will first add it to the Activity’s layout XML file:

Finally, we initialize it in the Activity and make use of it’s methods in order to change the ArticleView’s state:
