How to Create a custom Dialog with Tabs (Android)

image from blog.smartthings.com


Just earlier working on an app, I realized I needed to display tabbed information to users in a dialog box. This is quite different from the usual Tabbed Activity.



Dependency

The first step is to make sure you have "'com.android.support:design" in your build.gradle file.

Layouts

Next is to create the layout xml files for the custom dialog and your fragment. Your custom dialog may look like this:

dialog_sample.xml

And for the purpose of this tutorial, we will use a minimal Fragment, like the one indicated below:

fragment_sample.xml



Implementation

Next up is, building the java classes for the dialog, the fragment adapter, and the fragments.

Here is a sample implementation of the viewpager's adapter:

CustomAdapter.java
Note: you must override getTitle for the Tabs to have proper names.

Below is also a sample fragment for illustration purposes, we'll keep it simple for now:

CustomFragment.java

Go ahead and create your dialog's class:

TabbedDialog.java


And there you have it, it displays similarly to what's shown below:
