android - 用xml创建的fragment如何进行数据的传递与更新？

Question

<android.support.v4.widget.DrawerLayout
        android:id="@+id/drawer_main"
        android:layout_width="match_parent"
        android:layout_height="match_parent">

        <include layout="@layout/content_main" />

        <fragment
            android:id="@+id/menu_drawer"
            android:name=".DrawerFragment"
            android:layout_width="240dp"
            android:layout_height="match_parent"
            android:layout_gravity="start" />
    </android.support.v4.widget.DrawerLayout>

这是mainactivity的布局，DrawerLayout的左边是一个侧滑菜单，里面是一个fragment，已经写死了，所以不需要初始化，打开程序的时候直接里面一次性更新了数据。

现在通过搜索界面会给mainactivity传递数据，求问怎样才能把数据传给fragment使用？

Answer 1

Use FragmentManager to find your Fragment and let it interact with other classes by constructing an interface. Of course, you can directly obtain the Fragment instance and call its methods.

Answer 2

Fragments can be loaded this way. transaction.replace(R.id.frame, fragment); Just write a set method in the fragment, so that passing the value is simple.
I have never tried this kind of writing to death. You can completely use the above method instead

Answer 3

1. Message bus EventBus, otto or RxBus

Answer 4

The following two methods:
1. Use event bus EventBus or RxBus
2. Write the set method in Fragment
