I m building an Android application using Kotlin. So this is the layout of my Activity

<?xml version="1.0" encoding="utf-8"?>
<androidx.constraintlayout.widget.ConstraintLayout

    android:layout_height="match_parent"
    android:orientation="vertical"
    android:background="@color/white"
    tools:context=".DeviceTypeListActivity">

    <androidx.fragment.app.FragmentContainerView
        android:id="@+id/headerFragmentContainer"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:name="it.eresult.silvermountain.HeaderFragment"
        app:layout_constraintTop_toTopOf="parent"
        app:layout_constraintStart_toStartOf="parent"
        app:layout_constraintEnd_toEndOf="parent"
        />

            />
        <TextView
            android:id="@+id/text_view_subtitle"
            android:layout_width="match_parent"

            app:layout_constraintTop_toBottomOf="@id/text_view_title"
            app:layout_constraintStart_toStartOf="parent"
            app:layout_constraintEnd_toEndOf="parent"
            android:gravity="center"
            android:textColor="@color/dark_grey"
            android:textSize="18sp"
            />

            app:layout_constraintVertical_bias="0.0">

            <ListView

                app:layout_constraintEnd_toEndOf="parent" />


        </androidx.constraintlayout.widget.ConstraintLayout>

        <androidx.fragment.app.FragmentContainerView
            android:id="@+id/footer_fragment_container"
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:name="it.eresult.silvermountain.FooterFragment"
            app:layout_constraintBottom_toBottomOf="parent"
            app:layout_constraintStart_toStartOf="parent"
            app:layout_constraintEnd_toEndOf="parent"
            />


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

This is the output enter image description here

Now I need to set gray color of background between the items of ListView:

Solution

  • In your ListView change the divider color

                android:divider="#F0F0F0" //grey color
            android:dividerHeight="15dp"
