Use Cases of the Magnifier API

Since the magnifier APIs are not restricted to text, this widget can be used for a variety of purposes, like magnifying difficult-to-read location names on maps and reading small print. There is existing integration between the magnifier and platform widgets like TextView, EditText, and WebView. Across applications, it offers uniform text manipulation. Depending on the context of your application, you can utilize the widget, which has a straightforward API, to magnify any View.

You may have encountered a magnified effect when you have scrolled over text view in recent versions of Android, and have wanted to integrate the same functionality in your app as well. In this article, we will learn how to work towards implementing the same in your app. The magnifier widget, which is accessible in Android 9 (API level 28) and higher, is a fictitious magnifying glass that shows an enlarged version of a selected View through an overlay window that serves as the lens.
