How to Implement Marquee Text in Android
Creating visually appealing text effects in Android applications can greatly enhance the user experience. One popular text effect is the "marquee" text, where the text scrolls horizontally across the screen. This guide will guide you through the steps to implement marquee text in an Android application.
Understanding Marquee Text
Marquee text is a scrolling text effect where content continually moves horizontally across the view. This effect is commonly used in news tickers, stock quotes, and special announcements to draw attention to important information.

Key Attributes Explained
android:ellipsize="marquee": This attribute specifies that the text should be displayed using the marquee effect when it overflows the TextView's width.
android:marqueeRepeatLimit="marquee_forever": This defines the number of times the marquee effect should repeat. Setting it to marquee_forever makes the text scroll indefinitely.
android:singleLine="true": This enforces the TextView to be a single line, ensuring the text scrolls properly.
android:focusable="true" & android:focusableInTouchMode="true": Making the TextView focusable allows it to gain the necessary focus to start the marquee effect.
android:scrollHorizontally="true": This allows the text to scroll horizontally.
android:freezesText="true": This attribute preserves the text state across various configuration changes.
Final Thoughts
Implementing marquee text in Android is a simple yet effective way to highlight important information in your app. By following the steps outlined above, you can easily create smooth, continuous scrolling text, adding a dynamic and engaging element to your Android user interface.
Marquee text not only grabs user attention but also provides a stylish way to present information succinctly within limited screen space. Give it a try in your next Android project to see how it enhances your app's interactivity and user experience.
