Android Studio Vertical ScrollView

Heading h1

Android Studio Vertical ScrollView is a part of the Android Layout Manager that allows user interfaces to scroll vertically.

Syntax

To use the Android Studio Vertical ScrollView, add the following XML code inside your Android layout file.

<ScrollView xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent">

    <!-- put your content or layout here -->

</ScrollView>

Example

Let's take a simple example where we will add some TextViews inside the ScrollView.

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="vertical">

    <ScrollView
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:scrollbars="none">

        <LinearLayout
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:orientation="vertical">

            <TextView
                android:layout_width="match_parent"
                android:layout_height="wrap_content"
                android:text="Line 1" />

            <TextView
                android:layout_width="match_parent"
                android:layout_height="wrap_content"
                android:text="Line 2" />

            <TextView
                android:layout_width="match_parent"
                android:layout_height="wrap_content"
                android:text="Line 3" />

            <!-- more TextViews can be added here -->

        </LinearLayout>
    </ScrollView>
</LinearLayout>

Output

The above code will display three TextView lines that can be scrolled vertically if it exceeds the screen limit.

Explanation

Android Studio Vertical ScrollView is a container that can hold only one child within its hierarchy, usually wrapped inside a LinearLayout or RelativeLayout. The ScrollView element enables you to create multiple TextView or other views that can be scrolled vertically.

While implementing scrollbar, you can choose whether to apply horizontal or vertical scrolling by setting the android:scrollbars attribute.

Use

Android Studio ScrollView is used to display large chunks of data that can't survey the screen size; in other words, It is put to use when you want to show content that's more extensive than the screen.

Important Points

• Android Studio Vertical ScrollView only holds one child view within its hierarchy.
• ScrollView has a limited height and width. By default, the height is calculated based on its child's height.
• ScrollView doesn't support nested scrolling.

Summary

The Android Studio Vertical ScrollView is a powerful and handy tool that allows a user to manage their screen layout and view long or complex content with ease. By adding the ScrollView element to your Android Studio layout file, you can effortlessly add scrolling functionality to your applications and improve the user experience overall.
