android - toolbar上的控件如何在fragment中使用

Question

布局是一个drawerLayout,如何使toolbar上的按钮在不同的fragment中相应不同的刷新事件?

Answer 1

Use your fragmentmanager to find the fragment on the top of the current stack, and then make a judgment

Answer 2

Set tags for each fragment

getSupportFragmentManager().beginTransaction().add(R.id.container, currentFragment,tag).commit()

In the click event, handle different fragments through Tag, and then handle the refresh event
