How can I write it with code? Plas write codes with fragment, not with activity

Answer 1

You can just simply add the second fragment(B) on top of existing fragment

supportFragmentManager
   .beginTransaction()
   .add(R.id.fragmentContainer, SecondFragment())
   .commit()

by default fragment B will transparent if no background is set, you can set it's background to some translucent color by adding following line in fragment's root container

android:background="#66FFFFFF"

color is in #AARRGGBB format, you can adjust the transparency by changing the 66 field
