How to achieve scrolling text on an Android device

There are multiple methods to implement text scrolling in Android, here is one simple approach:

1. Add a TextView component in the XML layout file and set its attribute to be scrollable.

<TextView
    android:id="@+id/scrollingText"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:scrollbars="vertical"
    android:maxLines="5"
    android:scrollbarStyle="insideOverlay"
    android:fadeScrollbars="false"
    android:text="Your text here"
    android:textSize="18sp"/>

1. In the Activity, locate the TextView component and set a scrolling effect for it.

TextView scrollingText = findViewById(R.id.scrollingText);
scrollingText.setMovementMethod(new ScrollingMovementMethod());

This allows the text displayed in the TextView to scroll vertically. If you need to customize the scrolling speed or other effects, you can achieve it through custom Views or using third-party libraries.
