布局
<android.support.v4.widget.NestedScrollView
android:layout_width="match_parent"
android:layout_height="match_parent"
app:layout_behavior="@string/appbar_scrolling_view_behavior">
<android.support.v7.widget.RecyclerView
android:id="@+id/mRecyclerView_question"
android:layout_width="match_parent"
android:layout_height="match_parent">
</android.support.v7.widget.RecyclerView>
</android.support.v4.widget.NestedScrollView>
NestedScrollView嵌套RecyclerView滑动不流畅或者RecyclerView错乱
mRecyclerView.setNestedScrollingEnabled(false); //添加一句这个就好
