Introduction

Strike through text is a formatting feature that allows you to add a line that crosses through a piece of text. In this tutorial, we will learn how to implement strike through functionality in an Android app. By the end of this tutorial, you will be able to create an app that can apply and remove strike through text on a TextView with the click of a button.

Understanding Strike Through Text

Before we begin coding, let's understand what strike through text is. It is a visual indicator that appears as a line crossing through a piece of text. This formatting is commonly used to denote completed or cancelled items.

Creating the User Interface

To build our app, we need to first create the user interface. We will add a TextView and a Button to the activity_main.xml layout file. Additionally, we will modify the text size of the TextView to make it more visually appealing.

Implementing the Strike Through Functionality

Now that our user interface is set up, we can proceed with implementing the strike through functionality. In the MainActivity.java file, we will first reference the views from the layout file. Then, we will set a click listener for the button and define the actions that occur when the button is clicked. We will use the setPaintFlags() method to apply or remove the strike through flag on the TextView.

Testing the App

With the implementation complete, it's time to test our app. We will run the app on an emulator or device and click on the strike through button to observe the changes in the TextView. We will ensure that the strike through is correctly applied and removed based on the current state of the text.

Conclusion

In this tutorial, we learned how to create an Android app that can apply and remove strike through text on a TextView. We covered the steps required to set up the user interface, implement the functionality, and test the app. Now, you have the knowledge to incorporate strike through formatting into your own Android apps.
