Use OnSuccessListener this way

progressBar.setVisibility(View.VISIBLE);
mDatabase.child("users").child(userId).setValue(user)
        .addOnSuccessListener(new OnSuccessListener<Void>() {
            @Override
            public void onSuccess(Void aVoid) {
                // Write was successful!
                // ...
                progressBar.setVisibility(View.GONE);
            }
        })
        .addOnFailureListener(new OnFailureListener() {
            @Override
            public void onFailure(@NonNull Exception e) {
                // Write failed
                // ...
                progressBar.setVisibility(View.GONE);
            }
        });

May in the onSucesslistener from your queries you have a foreach or for, you may need to add percent to your progress bar, I'm kinda new to android so it may not work or have better solution.

Set progressBarhorizontal.visibility = View.VISIBLE in your activity and after finishing read data set progressBarhorizontal.visibility = View.GONE
