Example 33 with AccessibilityNodeInfo

use of android.view.accessibility.AccessibilityNodeInfo in project robolectric by robolectric.

the class ShadowAccessibilityNodeInfo method obtain.

@Implementation

     * We keep a separate list of actions for each object newly obtained
     * from a view, and perform a shallow copy during getClone. That way the
     * list of actions performed contains all actions performed on the view
     * by the tree of nodes initialized from it. Note that initializing two
     * nodes with the same view will not merge the two lists, as so the list
     * of performed actions will not contain all actions performed on the
     * underlying view.
