                Toast.makeText(ListItem.this,listproduct.get(newposition)+"",Toast.LENGTH_SHORT).show();
                Intent i=new Intent(ListItem.this,AddOrder.class);
                i.putExtra("position",listproduct.get(newposition));
                //adapternew.notifyDataSetChanged();
                 startActivity(i);
            }
        });



    }
}

here is the code that is to show the list view item and i want to know whether the value in list view come up when clicking the search bar

<?xml version="1.0" encoding="utf-8"?>
<androidx.constraintlayout.widget.ConstraintLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent">


    <SearchView
        android:id="@+id/Search"

        android:layout_width="match_parent"
        android:layout_height="56dp"
        android:layout_alignParentTop="true"
        android:iconifiedByDefault="false"
        android:queryHint="Search Here"
        app:layout_constraintBottom_toBottomOf="parent"
        app:layout_constraintHorizontal_bias="0.0"
        app:layout_constraintLeft_toLeftOf="parent"
        app:layout_constraintRight_toRightOf="parent"
        app:layout_constraintTop_toTopOf="parent"
        app:layout_constraintVertical_bias="0.00" />


    <ScrollView
        android:id="@+id/Scroll"
        android:layout_width="100dp"
        android:layout_height="150dp"
        tools:layout_editor_absoluteX="-8dp"
        tools:layout_editor_absoluteY="396dp">


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

        </LinearLayout>
    </ScrollView>

    <androidx.appcompat.widget.Toolbar
        android:id="@+id/toolbar2"
        android:layout_width="match_parent"
        android:layout_height="5dp"
        android:background="?attr/colorPrimary"
        android:minHeight="?attr/actionBarSize"
        android:theme="?attr/actionBarTheme"
        tools:layout_editor_absoluteX="9dp"
        tools:layout_editor_absoluteY="2dp" />

    <ListView
        android:id="@+id/Listview"
        android:layout_width="match_parent"
        android:layout_height="300dp"
        android:layout_below="@id/Search"
        app:layout_constraintBottom_toBottomOf="parent"
        app:layout_constraintHorizontal_bias="0.100"
        app:layout_constraintLeft_toLeftOf="parent"
        app:layout_constraintRight_toRightOf="parent"
        app:layout_constraintTop_toTopOf="parent"
        app:layout_constraintVertical_bias="0.200">

    </ListView>
</androidx.constraintlayout.widget.ConstraintLayout>

and this is the xml file of the listview

Solution

I think this is the code you are wanting.

No need to use scrollview here because ListView itself is scrollable. LinearLayout with Vertical Orientation will solve your issue

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical">

<androidx.appcompat.widget.Toolbar
    android:id="@+id/toolbar2"
    android:layout_width="match_parent"
    android:layout_height="5dp"
    android:background="?attr/colorPrimary"
    android:minHeight="?attr/actionBarSize"
    android:theme="?attr/actionBarTheme"
    tools:layout_editor_absoluteX="9dp"
    tools:layout_editor_absoluteY="2dp" />


<SearchView
    android:id="@+id/Search"
    android:layout_width="match_parent"
    android:layout_height="56dp"
    android:layout_alignParentTop="true"
    android:iconifiedByDefault="false"
    android:queryHint="Search Here"/>

<ListView
    android:id="@+id/Listview"
    android:layout_width="match_parent"
    android:layout_height="300dp"
    android:layout_marginTop="10dp">

</ListView>
</LinearLayout>
