Modern Android App Development with Java

Loading data from the network can take time, especially with a weak internet connection. Currently, while data is loading, the user sees a blank screen, which may be confusing. That’s why we need to introduce some kind of loading indicator.

We can show a simple `ProgressBar`, similar to what we did on the login screen, in the middle of the screen while data is loading.

Let’s start by declaring `ProgressBar` in the `activity_blog_details` file and constrain it to the middle of the screen. Leave the `ProgressBar` visible by default.

In this lesson, we will look at how to add a loading indicator when blog data is loading.
