My list view is not scrolling when i used it as child of scrollview

Question

I am trying to add list view under scroll view so that i can scroll whole page as well as my list view but my list view is not scrolling while my whole page is scrolling.

This is my XML :

          <?xml version="1.0" encoding="utf-8"?>
          <RelativeLayout 
            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"
             android:background="@color/gray">
             <ScrollView
                android:layout_width="match_parent"
                android:layout_height="match_parent"
                android:layout_below="@+id/toolbar"
                android:background="@color/white">


             <LinearLayout
               android:id="@+id/layout_form"
               android:layout_width="match_parent"
               android:layout_height="match_parent"
               android:orientation="vertical">

                 <android.support.v4.view.ViewPager
                    android:id="@+id/viewPager"
                    android:layout_width="match_parent"
                    android:layout_height="200dp"
                    android:layout_marginBottom="5dp"
                    android:background="@color/trans_white"/>

                 <ListView
                   android:layout_width="match_parent"
                   android:layout_height="match_parent"
                   android:id="@+id/list_prdt_detail"
                   android:divider="@color/white"
                   android:layout_marginBottom="50dp"
                   android:scrollbars="vertical"/>

                 </LinearLayout>

                 </ScrollView>


                  <LinearLayout
                     android:layout_width="match_parent"
                     android:layout_height="wrap_content"
                     android:orientation="horizontal"
                     android:weightSum="2"
                     android:layout_gravity="center"
                     android:gravity="center"
                     android:layout_alignParentBottom="true">

                  <TextView
                   android:layout_width="match_parent"
                   android:layout_height="wrap_content"
                   android:text="ADD TO CART"
                   android:background="@color/orange"
                   android:layout_weight="1"
                   android:layout_gravity="center"
                   android:gravity="center"
                   android:padding="20dp"
                   android:textColor="@color/white"
                   android:fontFamily="sans-serif"/>

                 <TextView
                   android:layout_width="match_parent"
                   android:layout_height="wrap_content"
                   android:text="BUY NOW"
                   android:background="@color/red"
                   android:layout_weight="1"
                   android:layout_gravity="center"
                    android:gravity="center"
                   android:padding="20dp"
                   android:textColor="@color/white"
                   android:fontFamily="sans-serif"/>

                 </LinearLayout>

               </RelativeLayout>

This is my java :

              listAdapter = new 
                 AdapterProddetail(Productdetail.this,al_prod_id,
                   al_prod_image,al_prod_name,al_prod_price,
                   al_prod_disc,al_prod_discount,al_prod_stock,al_prod_cc);
                   list_prdt_detail.setAdapter(listAdapter);
                   list_prdt_detail.setOnItemClickListener(this);
                   list_prdt_detail.setOnTouchListener(new 
                     ListView.OnTouchListener() {

                       public boolean onTouch(View v, MotionEvent event) {
                          int action = event.getAction();
                           switch (action) {
                                    case MotionEvent.ACTION_DOWN:
                                  // Disallow ScrollView to intercept touch 
                                     events.
                     v.getParent().requestDisallowInterceptTouchEvent(true);
                      break;
                     case MotionEvent.ACTION_UP:
                    // Allow ScrollView to intercept touch events.
                    v.getParent().requestDisallowInterceptTouchEvent(false);
                    break;
                    } // Handle ListView touch events.
                       v.onTouchEvent(event);
                      return true;
                    }
                 });

I have add java code that will disallow scroll intercept but still list view not scrolling.Please help me to overcome this situation.

Do not use ListView inside ScrollView. Use NestedScrollView instead of ScrollView.

OR

you can try it with setting android:nestedScrollingEnabled="true" to ListView

Try this:

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout
    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"
    android:background="@android:color/darker_gray">
    <ScrollView
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:layout_below="@+id/toolbar"
        android:background="@android:color/white">

        <LinearLayout
            android:id="@+id/layout_form"
            android:layout_width="match_parent"
            android:layout_height="match_parent"
            android:orientation="vertical">

            <android.support.v4.view.ViewPager
                android:id="@+id/viewPager"
                android:layout_width="match_parent"
                android:layout_height="200dp"
                android:layout_marginBottom="5dp"
                android:background="#88ffffff"/>

            <ListView
                android:layout_width="match_parent"
                android:layout_height="match_parent"
                android:id="@+id/list_prdt_detail"
                android:divider="@android:color/white"
                android:layout_marginBottom="50dp"
                android:scrollbars="vertical"
                android:nestedScrollingEnabled="true"/>

        </LinearLayout>
    </ScrollView>

    <LinearLayout
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:orientation="horizontal"
        android:weightSum="2"
        android:layout_gravity="center"
        android:gravity="center"
        android:layout_alignParentBottom="true">

        <TextView
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:text="ADD TO CART"
            android:background="@android:color/holo_orange_light"
            android:layout_weight="1"
            android:layout_gravity="center"
            android:gravity="center"
            android:padding="20dp"
            android:textColor="@android:color/white"
            android:fontFamily="sans-serif"/>

        <TextView
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:text="BUY NOW"
            android:background="@android:color/holo_red_dark"
            android:layout_weight="1"
            android:layout_gravity="center"
            android:gravity="center"
            android:padding="20dp"
            android:textColor="@android:color/white"
            android:fontFamily="sans-serif"/>

    </LinearLayout>
</RelativeLayout>

Hope this will help~

In your code, v.getParent() refers to the LinearLayout and not the ScrollView. Use v.getParent().getParent().

Also, as #Ferdous Ahamed mentioned, you should use NestedScrollView instead of ScrollView
