        RecyclerView myrv = view.findViewById(R.id.recyclerview_id_Horizental_badr_farsi);
        myAdapter = new RecyclerViewAdapter(getContext(), lstItems);
        myrv.setLayoutManager(new LinearLayoutManager(getContext(), LinearLayoutManager.HORIZONTAL, false));
        myrv.setAdapter(myAdapter);
        //vertical mode
        RecyclerView verticalmode = view.findViewById(R.id.recyclerview_id_vertical_badr_farsi);
        myAdapter = new RecyclerViewAdapter(getContext(), lstItems);
        verticalmode.setLayoutManager(new GridLayoutManager(getContext(), 3));
        verticalmode.setAdapter(myAdapter);
        return view;

只需更改 scrollview至<android.support.v4.widget.NestedScrollView 你可以解决你的问题

试试这个

<?xml version="1.0" encoding="utf-8"?>
<android.support.v4.widget.NestedScrollView xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    tools:context=".multi.TabFragment">

    <LinearLayout
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:orientation="vertical">

        <EditText
            android:id="@+id/searchintabbadrkurdi"
            android:layout_width="match_parent"
            android:layout_height="wrap_content" />
                <android.support.v7.widget.RecyclerView
                    android:id="@+id/recyclerview_id_badr_kurdish_hor"
                    android:layout_width="match_parent"
                    android:layout_height="wrap_content">

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

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

    </LinearLayout>

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