Recyclerview Inside Scrollview, Some Items Are Not Shown

I had a RecyclerView in ScrollView like this:

Solution 1:

I found the solution myself: replace ScrollView with NestedScrollView and keep recyclerView.setNestedScrollingEnabled(false). I don't know if this is what NestedScrollView is made for but it works.

NOTICE:

1. NestedScrollView is not a child of ScrollView but of FrameLayout.
2. This solution will also bring some bugs with self-simulated adjustResize.

Solution 2:

The best solution is to keep multiple Views in a Single View / View Group and then keep that one view in the SrcollView. ie.

Format -

<ScrollView><AnotherView><RecyclerView><TextView><AndOtherViews>
  </Another View>
</ScrollView>

Eg.

<ScrollViewandroid:layout_width="match_parent"android:layout_height="match_parent"><TextViewandroid:text="any text"android:layout_width="match_parent"android:layout_height="wrap_content"/><TextViewandroid:text="any text"android:layout_width="match_parent"android:layout_height="wrap_content"/></ScrollView>

Another Eg. of ScrollView with multiple Views

<ScrollView
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:layout_weight="1"><LinearLayout
            android:layout_width="match_parent"
            android:layout_height="0dp"
            android:orientation="vertical"
            android:layout_weight="1"><androidx.recyclerview.widget.RecyclerView
                android:id="@+id/imageView"
                android:layout_width="match_parent"
                android:layout_height="wrap_content"
                android:background="#FFFFFF"/><LinearLayout
                android:layout_width="match_parent"
                android:layout_height="wrap_content"
                android:paddingHorizontal="10dp"
                android:orientation="vertical"><TextView
                    android:layout_width="match_parent"
                    android:layout_height="wrap_content"
                    android:text="@string/CategoryItem"
                    android:textSize="20sp"
                    android:textColor="#000000"/><TextView
                    android:textColor="#000000"
                    android:text="₹1000"
                    android:textSize="18sp"
                    android:layout_width="match_parent"
                    android:layout_height="wrap_content"/><TextView
                    android:textColor="#000000"

                    android:layout_width="match_parent"
