Accessibility order on Android
Assistive technologies try to determine a logical accessibility order based on the placement and properties of the elements on the screen. In Left-to-Right languages, the order goes from top to bottom, from left to right. If this order is not optimal, you can override the accessibility order that assistive technologies follow.
On Android, you can set the accessibility order in XML, or modify the accessibility order in code. You can use the android:accessibilityTraversalAfter and android:accessibilityTraversalBefore properties in XML. Or you can use the setAccessibilityTraversalBefore and setAccessibilityTraversalAfter methods in code.
header.setAccessibilityTraversalBefore(R.id.description)
list.setAccessibilityTraversalAfter(R.id.description)
