Use these two lines in your Fragment Container.

android:layout_height="match_parent" app:layout_constraintBottom_toTopOf="@+id/nvBottomNavigationMenu"

The flickering happens because of the default crossfade animation that the bottom navigation uses. You can overwrite the animation by creating the following files in the res\animator package.

nav_default_enter_anim.xml
nav_default_exit_anim.xml
nav_default_pop_enter_anim.xml
nav_default_pop_exit_anim.xml

This should be the content of those files.

<?xml version="1.0" encoding="utf-8"?>
<set xmlns:android="http://schemas.android.com/apk/res/android">
    <!-- Overwrite the default animation. -->
</set>

I have find solution for my problem i'm having flickering because my background color is black if i change it to white i didn't have any flicker for that i have update theme by adding bellow lines.

    <item name="android:windowBackground">#000000</item>
    <item name="android:colorBackground">#000000</item>

By adding these lines i have avoided the flicker problem.
