如何更改双击和长按的Android对讲说明 [英] How to change Android talkback instructions for double tap and long press

问题描述

我有一个带有长按动作处理程序的视图。我使用内容描述来设置当视图获得焦点时对讲会讲话的消息。

I have a view that has a long press action handler. I use the content description to set the message Talkback speaks when the view gets focus.

当前，它说的是获得焦点后我的内容描述，并在短暂的停顿后说：

Currently it says my content description right after getting a focus, and after a short pause says:

双击以激活，双击并长按

Double tap to activate, double tap and hold for long press

我想将此消息更改为

双击以动作1 ，双击并按住动作2

有没有办法？

我查看了 onPopulateAccessibilityEvent（），它会得到 TYPE_VIEW_ACCESSIBILITY_FOCUSED 事件，但是我无法更改所需的消息。

I looked into onPopulateAccessibilityEvent(), it gets TYPE_VIEW_ACCESSIBILITY_FOCUSED event, but I wasn't able to change the desired message.

我错过了一些简单的东西吗？

Am I missing something simple?

推荐答案

似乎<$自 alanv 发布答案以来，c $ c> AccessibilityAction 稍有变化。这是使用 ViewCompat 的可行解决方案：

It seems AccessibilityAction has changed slightly since alanv posted his answer. Here is a working solution using ViewCompat:

ViewCompat.setAccessibilityDelegate(view, new AccessibilityDelegateCompat() {
    @Override
    public void onInitializeAccessibilityNodeInfo(View host, AccessibilityNodeInfoCompat info) {
        super.onInitializeAccessibilityNodeInfo(host, info);
        // A custom action description. For example, you could use "pause"
        // to have TalkBack speak "double-tap to pause."
        CharSequence description = host.getResources().getText(R.string.my_click_desc);
        AccessibilityActionCompat customClick = new AccessibilityActionCompat(
                    AccessibilityNodeInfoCompat.ACTION_CLICK, description);
        info.addAction(customClick);
    }
});
