Display Issues in under larger scaling settings

[gaosher]

Describe the bug
i found some adaptive display bugs under largest font size and largest display size.

1. Button "New user?" and Button "Restore" can't be displayed completely.
   
   i belive the buggy views are Button @id/fragment_setup_init_button_new, and @id/fragment_setup_init_button_restore_backup in activity_setup.xml .
2. text "Let's say your username is..." can't be displayed completely.
   
   i belive the buggy view is LinearLayout @id/setup_how_1_ll in fragment_setup_how1.xml .
3. text "Either on the fly or generated beforehand..." can't be displayed completely.
   
   i belive the buggy view is LinearLayout @id/setup_how_2_SV in fragment_setup_how2.xml .
4. text "Let's say a spammer get..." can't be displayed completely.
   
   i belive the buggy view is LinearLayout @id/setup_how_3_ll in fragment_setup_how3.xml .
