需求:在scrollview 裏嵌套 recycleview ,recycleview不能滑動,可是它全部的條目還須要所有顯示出來,隨着scrollview 滑動html
解決:在recycleview 外嵌套一層relativeLayout,並 設置 android:descendantFocusability="blocksDescendants" 屬性,在activity中 給recycleview 設置setNestedScrollingEnabled(false);android
<ScrollView
android:layout_width="match_parent"
android:layout_height="match_parent">
<RelativeLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:descendantFocusability="blocksDescendants">
<android.support.v7.widget.RecyclerView
android:layout_width="match_parent"
android:layout_height="match_parent">
</android.support.v7.widget.RecyclerView>
</RelativeLayout>
</ScrollView>
