Dark Theme in android 9.0 changes my app layouts ugly

问题

I am just designing my layout without expecting any of the problems, but one-day android 9.0 launched and I brought the phone and installed my app in it and tried my app opening it with night mode ON and I started to see white color layout changes in dark and my minds goes block. I want to know how to disable the theme.

I tried changing themes, changing the background colors none of those works

<RelativeLayout
        android:layout_width="190dp"
        android:layout_height="200dp"
        android:layout_marginTop="-15dp"
        android:layout_below="@+id/tableTxt"
        android:background="@drawable/table_no_orders_border"
        android:theme="@style/ThemeOverlay.AppCompat.Light"
        android:layout_centerHorizontal="true">

    <android.support.v7.widget.CardView
            android:id="@+id/cv_one_login"
            android:layout_width="189dp"
            android:layout_height="199dp"
            android:layout_centerHorizontal="true"
            android:elevation="10dp"
            app:cardCornerRadius="1dp"
            app:cardElevation="10dp"
            android:layout_marginTop="0.1dp">

            <android.support.v4.widget.NestedScrollView
                    android:id="@+id/sv1"
                    android:layout_width="match_parent"
                    android:layout_height="147dp"
                    android:scrollbars="vertical"
                    android:scrollbarSize="10dp"
                    android:isScrollContainer="true">
                <TextView
                        android:id="@+id/tableItems"
                        android:layout_width="match_parent"
                        android:layout_height="match_parent"
                        android:text="@string/table"
                        android:layout_marginStart="5dp"
                        android:layout_marginTop="13dp"
                        android:textColor="@color/TextcolorforBlack"/>
            </android.support.v4.widget.NestedScrollView>
            <TextView
                    android:id="@+id/totalTableBill"
                    android:layout_width="match_parent"
                    android:layout_height="match_parent"
                    android:text="@string/total_bill"
                    android:textColor="@color/SettingsColor"
                    android:layout_below="@id/sv1"
                    android:textAlignment="gravity"
                    android:gravity="bottom"
                    android:layout_marginStart="5dp"/>
        </RelativeLayout>
    </android.support.v7.widget.CardView>
</RelativeLayout>

I need my layout as it is designed. even if the theme got applied also it should be the same.

You can change App theme to any theme in the App Manifest file like,

<application 
    android:theme="@android:style/Theme.Holo"/>

<application 
    android:theme="@android:style/Theme.Holo.Light"/>

<application 
    android:theme="@android:style/Theme.Black"/>

<application 
    android:theme="@android:style/Theme.DeviceDefault"/>

Or you can customize theme in the styles.xml file and then Apply in Manifest

<style name="AppBaseTheme" parent="android:Theme.Holo.Light"/>
<style name="AppTheme" parent="AppBaseTheme"/>

Now in Manifest file

<application 
    android:theme="@style/AppBaseTheme"/>

You can also preview themes in the preview window in Android Studio.
