you type casting wrong , make Following changes

 ConstraintLayout txtSendMail;
    ConstraintLayout txtCall;
    ConstraintLayouttxtEmailFeedback;
    ConstraintLayout txtWebsite;

    txtSendMail=(ConstraintLayout)findViewById(R.id.txt_send_mail);
    txtCall=(ConstraintLayout)findViewById(R.id.txt_call);
    txtEmailFeedback=(ConstraintLayout)findViewById(R.id.txt_email_feedback);
    txtWebsite=(ConstraintLayout)findViewById(R.id.txt_website);
