How to make a textview scrollable in android ?

 There are a few ways to make a TextView scrollable in Android. One way is to use the android:scrollbars attribute in the XML layout file to enable scrollbars on the TextView. For example:

<TextView
    android:id="@+id/my_textview"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:text="Hello, World!"
    android:scrollbars="vertical" />

In this example, the scrollbars attribute is set to "vertical", which will enable a vertical scrollbar on the TextView. You can also set it to "horizontal" to enable a horizontal scrollbar, or "both" to enable both vertical and horizontal scrollbars.

Another way to make a TextView scrollable is to use a ScrollView. A ScrollView is a container that allows the user to scroll through a single child view, such as a TextView. For example:

<ScrollView
    android:layout_width="match_parent"
    android:layout_height="wrap_content">

    <TextView
        android:id="@+id/my_textview"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:text="Hello, World!" />

</ScrollView>

In this example, the TextView is placed inside a ScrollView, which allows the user to scroll through the TextView.

You can also programmatically make a TextView scrollable by using the setMovementMethod() method and passing it a ScrollingMovementMethod object. For example:

val myTextView: TextView = findViewById(R.id.my_textview)
myTextView.movementMethod = ScrollingMovementMethod()

In this example, the movementMethod property of the TextView is set to a new ScrollingMovementMethod object, which allows the TextView to be scrolled.

In summary, to make a TextView scrollable in Android, you can use the android:scrollbars attribute, use a ScrollView, or programmatically set the movementMethod property of the TextView to a ScrollingMovementMethod object.
