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

try this way
