推荐答案

如果您想捕获项目的点击，请实施

If you want to capture the click on your item, implement

public boolean onOptionsItemSelected(MenuItem item)

然后:

如果您的活动中包含片段，则系统会先调用 活动的onOptionsItemSelected()，然后是每个片段(在 每个片段的添加顺序)，直到一个返回true或全部 片段已被调用.

If your activity includes fragments, the system first calls onOptionsItemSelected() for the activity then for each fragment (in the order each fragment was added) until one returns true or all fragments have been called.

您可以遵循官方参考:
