ListView showing only first element in NestedScrollView

[Milos Gojic]

I need to make a list in my NestedScrollView but showing only first element. I tried with android:fillViewport="true" but hothing happened. I know that ListView has scrollable incorporated in itself.

my xml :

<layout >
<data>
    <variable
        name="home"
        type="com.nswd.successplan.ui.fragments.homeFragment.HomeViewModel" />
</data>
<androidx.core.widget.NestedScrollView
    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:background="#f0f4f7"
    android:fillViewport="true"
    tools:context=".ui.fragments.homeFragment.HomeFragment">

    <androidx.constraintlayout.widget.ConstraintLayout
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:layout_margin="8dp"
        android:background="#f0f4f7">

       // XML code ...

        <LinearLayout
            android:id="@+id/pie_chart_expenditures_LL"
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:background="#ffffff"
            android:orientation="vertical"
            app:layout_constraintBottom_toTopOf="@+id/list_view_pie_chart_legend"
            app:layout_constraintEnd_toEndOf="parent"
            app:layout_constraintStart_toStartOf="parent"
            app:layout_constraintTop_toBottomOf="@+id/pie_chart_expenditures_TV">

            <com.github.mikephil.charting.charts.PieChart
                android:id="@+id/pie_chart_reports_home"
                android:layout_width="match_parent"
                android:layout_height="400dp" />
        </LinearLayout>


        <ListView
            android:id="@+id/list_view_pie_chart_legend"
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:background="#ffffff"
            android:layout_marginBottom="8dp"
            app:layout_constraintBottom_toTopOf="parent"
            app:layout_constraintEnd_toEndOf="parent"
            app:layout_constraintStart_toStartOf="parent"
            app:layout_constraintTop_toBottomOf="@+id/pie_chart_expenditures_LL"
            tools:listitem="@layout/pie_chart_list_item" />
    </androidx.constraintlayout.widget.ConstraintLayout>
</androidx.core.widget.NestedScrollView>

my pie_chart_list_item:

<layout>
    <data>
        <variable
            name="legend"
            type="com.nswd.successplan.model.PieChartLegendModel" />
    </data>

    <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:layout_marginBottom="10dp"
        android:orientation="horizontal"
        android:padding="4dp">

        <ImageView
            android:id="@+id/legend_color"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:src="@drawable/ic_dot_list_item_pie_chart" />

        <TextView
            android:id="@+id/expenditure"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:layout_gravity="center"
            android:layout_marginStart="10dp"
            android:layout_weight="1"
            android:text="Debt Payments"
            android:textColor="#197ad8" />

        <TextView
            android:id="@+id/costs_expenditure"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:layout_weight="1"
            android:gravity="end"
            android:text="7,555" />
    </LinearLayout>
</layout>

Change height of constraint layout to match_parent and see.
