Android: ScrollView not working in RelativeLayout properly

Question

I have problem with ScrollView. I'm trying to get it in Relative Layout. I have tried some solutions,but nothing works.I tried setting my relative layout's height to match_parent but it doesn't work also. I can get it to work with linear layout but I don't want to use it for some reason.

MY Xml code: `

Answer 1

RecyclerView itself a ScrollView .

Solution

Call NestedScrollView instead of ScrollView .

STRUCTURE

<android.support.v4.widget.NestedScrollView
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
       >

            <android.support.v7.widget.RecyclerView
                android:id="@+id/list"
                android:layout_width="match_parent"
                android:layout_height="match_parent"
                android:orientation="vertical"
             />

    </android.support.v4.widget.NestedScrollView>

FYI

You should add

recyclerViewOBJ.setNestedScrollingEnabled(false);

If this property is set to true the view will be permitted to initiate nested scrolling operations with a compatible parent view in the current hierarchy. If this view does not implement nested scrolling this will have no effect. Disabling nested scrolling while a nested scroll is in progress has the effect of stopping the nested scroll.

Answer 2

You should take a scrollview outside of Relative layout

Answer 3

Set your Scrollview to NestedScrollView

<android.support.v4.widget.NestedScrollView>
 <android.support.v7.widget.RecyclerView>
</android.support.v7.widget.RecyclerView>
</android.support.v4.widget.NestedScrollView>

In your recyclerview

recyclerView.setNestedScrollingEnabled(false); 
recyclerView.setHasFixedSize(false);
