Answer 1

Ваш журнал ошибок показывает, что произошла неизвестная ошибка в раздувании один из ваших классов.

java.lang.RuntimeException: Unable to start activity ComponentInfo{com.cuet.teachersroom/com.cuet.teachersroom.Teachers_Room}: android.view.InflateException: Binary XML file line #20: Error inflating class <unknown> 

Так мы действительно должны взглянуть на соответствующем XML-файл, который com.cuet.teachersroom.Teachers_Room звонит, чтобы увидеть, что происходит.
