卡片视图未出现,滚动视图也无法正常工作
Card View is not appear and also scrollview is not working
<RelativeLayout>
<android.support.v7.widget.CardView>
.
.//this card view is showing
.
</android.support.v7.widget.CardView>
<ScrollView>
<RelativeLayout>
<android.support.v7.widget.CardView>
.
.//this card view is not showing
.
</android.support.v7.widget.CardView>
<android.support.v7.widget.RecyclerView>
//data is previewing but not scrolling
</android.support.v7.widget.RecyclerView>
</RelativeLayout>
</ScrollView>
</RelativeLayout>
但是如果我将第二个 cardview 放在 scrollview 之外而不是显示。我不明白是什么问题。如果有人可以提供帮助,非常感谢。
我试过的解决方法:-
使用 nestedscrollview 而不是滚动视图。
如果问题格式或风格不符合 Stack Overflow 指南,请告诉我,以便将来我会以更好的方式提问。而不是对它投反对票。

回答自己的问题,如果以后有人遇到同样的问题,这里是正确答案:-
https://github.com/amardeshbd/android-recycler-view-wrap-content
使用LinearLayout 代替Relative 布局并将Recyclerview 包装到relativelayout。
<RelativeLayout>
<android.support.v7.widget.CardView>
.
.//this card view is showing
.
</android.support.v7.widget.CardView>
<ScrollView>
<RelativeLayout>
<android.support.v7.widget.CardView>
.
.//this card view is not showing
.
</android.support.v7.widget.CardView>
<android.support.v7.widget.RecyclerView>
//data is previewing but not scrolling
</android.support.v7.widget.RecyclerView>
</RelativeLayout>
</ScrollView>
</RelativeLayout>
