Answer 1

Ok i got an answer to my question, acttualy my app already has dark elements and when i add a white background to an imageview or some more elements but it changes to dark grey in the dark mod of the device which i dont want ,so i got an solution to this issue

Step 1

Delete the night/dark theme.xml in the values

Step 2

In the normal/light theme.xml in the values change the

<style name="Theme.MyAppNotFinal" parent="Theme.MaterialComponents.DayNight.NoActionBar">

to

<style name="Theme.MyAppNotFinal" parent="Theme.MaterialComponents.Light.NoActionBar">

Step 3

In the same theme.xml // light/normal theme

add this line

 <item name="android:forceDarkAllowed" tools:targetApi="q">false</item>

inside the style

like this

<style name="Theme.MyAppNotFinal" parent="Theme.MaterialComponents.Light.NoActionBar">
<item name="android:forceDarkAllowed" tools:targetApi="q">false</item>
</style>

this method worked for me if anyone still have some issues please check the bellow question it has many answers hope it will work for you
