Android recycler view inside on scrollview [duplicate]

Question

i have

MAIN VIEW

<ScrollView android:layout_width="match_parent" android:layout_height="match_parent"> <androidx.recyclerview.widget.RecyclerView android:id="@+id/recycler_products" android:layout_width="match_parent" android:layout_height="wrap_content" android:nestedScrollingEnabled="false" /> </ScrollView>

On my template adapter, i have a another recycler adapter for child views

<?xml version="1.0" encoding="utf-8"?> <androidx.cardview.widget.CardView android:layout_width="match_parent" android:layout_height="wrap_content" xmlns:android="http://schemas.android.com/apk/res/android" xmlns:app="http://schemas.android.com/apk/res-auto"> <LinearLayout android:layout_width="match_parent" android:layout_height="match_parent" android:orientation="vertical" android:weightSum="1"> <TextView android:id="@+id/title_product" android:layout_width="match_parent" android:layout_height="wrap_content" android:layout_weight=".2" android:background="@color/GRAY" android:text="TextView" /> <androidx.recyclerview.widget.RecyclerView android:id="@+id/recycler_for_specification_items" android:layout_width="match_parent" android:layout_height="wrap_content" android:visibility="visible" app:layoutManager="androidx.recyclerview.widget.LinearLayoutManager" android:nestedScrollingEnabled="false" /> </LinearLayout> </androidx.cardview.widget.CardView>

The code work, but when user scroll on android device, the parent scrollView does not allow me to scroll over the recycler view (1)

Use NestedScrollview instead of scrollview and use android:nestedScrollingEnabled="false" for recycler_products recyclerview not in both

 <androidx.core.widget.NestedScrollView android:layout_width="match_parent" android:layout_height="match_parent"> <androidx.recyclerview.widget.RecyclerView android:id="@+id/recycler_products" android:layout_width="match_parent" android:layout_height="wrap_content" android:nestedScrollingEnabled="false" /> </androidx.core.widget.NestedScrollView>

If you are not able to scroll it is because of this line

android:nestedScrollingEnabled="false".

Change it to True, so you can enable the scrolling:

android:nestedScrollingEnabled="true".

In you code you have recylerview inside scroll view, this is wrong.

Option 1: If scroll view has not any other child view than remove it and just use recyclerview and also remove android:nestedScrollingEnabled="false

And your Main View code looks like this;

<androidx.recyclerview.widget.RecyclerView android:id="@+id/recycler_products" android:layout_width="match_parent" android:layout_height="wrap_content" />

Option 2: If scroll view has also other child including recyclerview than you should use nestedscrollview like below code:

<androidx.core.widget.NestedScrollView android:layout_width="match_parent" android:layout_height="wrap_content" android:scrollbars="none"> <LinearLayout android:layout_width="match_parent" android:layout_height="wrap_content" android:focusableInTouchMode="true" android:orientation="vertical"> <ImageView android:id="@+id/sellerProduct" android:layout_width="match_parent" android:layout_height="200dp" android:adjustViewBounds="true" android:src="@drawable/iphone" android:scaleType="fitXY" android:contentDescription="@string/app_name" /> <androidx.recyclerview.widget.RecyclerView android:layout_width="match_parent" android:layout_height="match_parent" android:scrollbars="vertical" android:nestedScrollingEnabled="false android:id="@+id/productList"/> </LinearLayout> </androidx.core.widget.NestedScrollView>
