Saat menggunakan dua atau lebih recyclerview dalam satu halaman, kemungkinan besar data item dari recyclerview tidak ditampilkan semua jika isinya banyak.

Namun hal ini terjadi pada HP android versi 8 (Oreo) ke atas. Untuk versi Nougat masih aman.

Contoh kodenya seperti berikut

<ScrollView
        android:id="@+id/scroll_view"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:background="#ffffff"
        android:layout_marginBottom="50dp"
        android:fillViewport="true"
        android:scrollbars="vertical"
        app:layout_behavior="@string/appbar_scrolling_view_behavior">
    
        <LinearLayout
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:orientation="vertical">

            <LinearLayout
                android:layout_width="match_parent"
                android:layout_height="match_parent"
                android:background="#f4f4f4"
                android:orientation="vertical">

                <android.support.v7.widget.RecyclerView
                    android:id="@+id/rv_satu"
                    android:layout_width="match_parent"
                    android:layout_height="match_parent"
                    android:layout_marginLeft="8dp"
                    android:layout_marginRight="8dp"
                    app:layout_behavior="@string/appbar_scrolling_view_behavior" />
            </LinearLayout>
        </LinearLayout>

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

            <LinearLayout
                android:layout_width="match_parent"
                android:layout_height="match_parent"
                android:background="#f4f4f4"
                android:orientation="vertical">

                <android.support.v7.widget.RecyclerView
                    android:id="@+id/rv_dua"
                    android:layout_width="match_parent"
                    android:layout_height="match_parent"
                    android:layout_marginLeft="8dp"
                    android:layout_marginRight="8dp"
                    app:layout_behavior="@string/appbar_scrolling_view_behavior" />
            </LinearLayout>
        </LinearLayout>
</ScrollView>

Agar bisa berjalan sesuai harapan, dimana semua item di dalam recyclerview bisa tampil, maka

– scrollview harus dirubah menjadi NestedScrollView

– menambahkan setNestedScrollingEnabled(false) di code java recyclerview

Hasilnya menjadi seperti di bawah ini:

<android.support.v4.widget.NestedScrollView
        android:id="@+id/scroll_view"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:background="#ffffff"
        android:layout_marginBottom="50dp"
        android:fillViewport="true"
        android:scrollbars="vertical"
        app:layout_behavior="@string/appbar_scrolling_view_behavior">
    
        <LinearLayout
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:orientation="vertical">

            <LinearLayout
                android:layout_width="match_parent"
                android:layout_height="match_parent"
                android:background="#f4f4f4"
                android:orientation="vertical">

                <android.support.v7.widget.RecyclerView
                    android:id="@+id/rv_satu"
                    android:layout_width="match_parent"
                    android:layout_height="match_parent"
                    android:layout_marginLeft="8dp"
                    android:layout_marginRight="8dp"
                    app:layout_behavior="@string/appbar_scrolling_view_behavior" />
            </LinearLayout>
        </LinearLayout>

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

            <LinearLayout
                android:layout_width="match_parent"
                android:layout_height="match_parent"
                android:background="#f4f4f4"
                android:orientation="vertical">

                <android.support.v7.widget.RecyclerView
                    android:id="@+id/rv_dua"
                    android:layout_width="match_parent"
                    android:layout_height="match_parent"
                    android:layout_marginLeft="8dp"
                    android:layout_marginRight="8dp"
                    app:layout_behavior="@string/appbar_scrolling_view_behavior" />
            </LinearLayout>
        </LinearLayout>
</android.support.v4.widget.NestedScrollView>

di code javanya:

rv_satu = (RecyclerView) view.findViewById(R.id.rv_satu);
GridLayoutManager gridLayoutManager = new GridLayoutManager(getActivity(), 3);
rv_satu.setLayoutManager(gridLayoutManager);
rv_satu.setItemAnimator(new DefaultItemAnimator());
rv_satu.setNestedScrollingEnabled(false);

rv_dua = (RecyclerView) view.findViewById(R.id.rv_dua);
GridLayoutManager gridLayoutManager = new GridLayoutManager(getActivity(), 3);
rv_dua.setLayoutManager(gridLayoutManager);
rv_dua.setItemAnimator(new DefaultItemAnimator());
rv_dua.setNestedScrollingEnabled(false);

Taraa… sudah keluar semua itemnya.

Semoga bermanfaat.
