android - 解释 ClickableViewAccessibility

Question

关于the SO swipe code , Android lint 给出了警告

OnSwipeTouchListener#onTouch should call View#performClick when a click is detected [ClickableViewAccessibility]

在description of the warning ，它说:

If a View that overrides onTouchEvent or uses an OnTouchListener does not also implement performClick and call it when clicks are detected, the View may not handle accessibility actions properly. Logic handling the click actions should ideally be placed in View#performClick as some accessibility services invoke performClick when a click action should occur.

您如何“正确处理辅助功能操作”？

Answer 1

出现警告是因为代码监听了 onTouchEvent(参见 docs, point 3)。有一个指向 solution for a click event 的指针，但这并没有解决是否需要处理滑动。

解决方法是使用触发与滑动事件相同的 Action 的按钮。然后，使用 @SuppressWarnings。
