java - Android ShareActionProvider 将不需要的项目添加到工具栏？

Question

为什么当我在 ShareActionProvider 中使用过一次时，我的工具栏会扩展并带有消息图标？我不想要这种行为。

Answer 1

Why does my toolbar expand with the message icon when i've used it once in the ShareActionProvider?

那是 ShareActionProvider 向用户提供最近或流行的共享操作，以便快速访问。引用 the documentation :

The share action provider retains a ranking for each share target, based on how often the user chooses each one. The more often a user chooses a target, the higher its rank; the most-commonly used target appears in the app bar as the default target.

I dont want this behaviour.

如果您打算使用 ShareActionProvider，我怀疑您在这件事上别无选择。您可以尝试调用setShareHistoryFilename()并为文件名提供 null 并查看是否会抑制该行为。
