Question

我想放置顶部布局SearchView。我在SearcView上有MyActivity，在它下面有RecyclerView，当我打开MyActivity时它首先显示RecyclerView，如果我想看到SearchView我向上滚动。我如何设置MyActivity，以便在我打开MyActivity时，它首先向我显示SearchView？

<ScrollView
android:layout_height="match_parent"
android:layout_width="match_parent"
xmlns:android="http://schemas.android.com/apk/res/android"
android:fillViewport="true">

 <LinearLayout
        android:layout_width="match_parent"
        android:layout_height="50dp"
        android:orientation="vertical">
        <SearchView
            android:layout_width="match_parent"
            android:layout_height="50dp"
            android:queryHint="Evento"
            android:id="@+id/cercaEvento"/>

    </LinearLayout>
 ......
</ScrollView>
