Success Criterion 1.4.10 - Level AA

Reflow

Ensure that all content on the screen remains readable even with the largest font. Content should be readable without having to scroll in two directions. Because the text is displayed larger, it can push other elements off the screen. Ensure content can still be reached, for example, by scrolling vertically.

Impact

  • Reflow allows visually impaired people to clearly follow where text begins and ends.

  • Scaled text might push elements off the screen. This results in a loss of information.

Check

Can all content be read with the largest font size?

This can be tested visually, enable the largest font size.

Solution

Support reflow

On Android, all elements should be placed in a scrollable layout, such as a ScrollView or RecyclerView. Never use fixed values for any heights or widths.

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

    <TextView
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:text="Content should scroll!" />
</ScrollView>
