Modify accessibility focus order

Question

Is it possible to change the accessibility focus order? For example, if I have 3 views side by side, with ids view1, view2, and view3, is there a simple way to make the accessi

For applications with minSdkVersion >= 22, you may set the traversal order for screen readers direct in the XML with android:accessibilityTraversalAfter:

<ImageView
    android:id="@+id/imageView"
    android:layout_width="30dp"
    android:layout_height="30dp"
    android:src="@drawable/ic_launcher" />

<ImageView
    android:id="@+id/imageView2"
    android:layout_width="30dp"
    android:accessibilityTraversalAfter="@id/imageView3"
    android:layout_height="30dp"
    android:src="@drawable/ic_launcher" />

<ImageView
    android:id="@+id/imageView3"
    android:layout_width="30dp"
    android:layout_height="30dp"
    android:src="@drawable/ic_launcher" />

For applications supporting lower API levels, the traversal order may be set programmatically with ViewCompat:

ViewCompat.setAccessibilityDelegate(imageView2, object : AccessibilityDelegateCompat() {
    override fun onInitializeAccessibilityNodeInfo(host: View?, info: AccessibilityNodeInfoCompat?) {
        info?.setTraversalAfter(imageView3)
        super.onInitializeAccessibilityNodeInfo(host, info)
    }
})

Please keep in mind that screen reader users rely on the consistency of the navigation, therefore, changing the focus order is an anti-pattern and should be avoided.
