from 1st edittext going to 2nd edittext, input mask not working

Question

I have 6 edittexts (will be using for OTP)
Each edittext will only allow 1 character and then transfer to another edittext

Here is the sample code:

et1.requestFocus()

et1.addTextChangedListener(new TextWatcher() {

public void onTextChanged(CharSequence s, int start,int before, int count {
    if(et1.getText().toString().length()==size){
        et2.requestFocus();
    }
}
public void beforeTextChanged(CharSequence s, int start,
                int count, int after) {}

public void afterTextChanged(Editable s) {
     et1.setTransformationMethod(new PasswordTransformationMethod());
}

});

What happens is, the et1, doesn't mask itself as dot/asterisk but the focus is transferred to et2.
But whenever I tap it again, it masks itself.

Edit: Already added inputType="numberPassword" in my XML but still not working

It looks like a duplicate question : https://stackoverflow.com/questions/12470067/how-to-automatically-move-to-the-next-edit-text-in-android — Catluc, Nov 22 '18 at 15:09
no its not. in my situation. I need the mask. the request focus is already working — MaChee Neraid, Nov 22 '18 at 15:11
@Catluc, have you carefully read my problem? my problem is the masking of edittext, not the requestfocus. please check it before suggesting duplicates. — MaChee Neraid, Nov 22 '18 at 15:53
