Answer 1

You can try this if you want to add some extra logic for delete the OTP, i create it based on the answer from A.R. make sure you set maxlength = 2 for all edittext

public class GenericTextWatcher implements TextWatcher
{
    private View view;
    private GenericTextWatcher(View view)
    {
        this.view = view;
    }
    @Override
    public void afterTextChanged(Editable editable) {
        // TODO Auto-generated method stub
        String text = editable.toString();
        switch (view.getId()) {

            case R.id.etOTP1:
                if (text.length() > 1) {
                    etOTP1.setText(String.valueOf(text.charAt(0)));
                    etOTP2.setText(String.valueOf(text.charAt(1)));
                    etOTP2.requestFocus();
                    etOTP2.setSelection(etOTP2.getText().length());
                }
                break;
            case R.id.etOTP2:
                if (text.length() > 1){
                    etOTP2.setText(String.valueOf(text.charAt(0)));
                    etOTP3.setText(String.valueOf(text.charAt(1)));
                    etOTP3.requestFocus();
                    etOTP3.setSelection(etOTP3.getText().length());
                }
                if (text.length() == 0){
                    etOTP1.requestFocus();
                    etOTP1.setSelection(etOTP1.getText().length());
                }
                break;
            case R.id.etOTP3:
                if (text.length() > 1){
                    etOTP3.setText(String.valueOf(text.charAt(0)));
                    etOTP4.setText(String.valueOf(text.charAt(1)));
                    etOTP4.requestFocus();
                    etOTP4.setSelection(etOTP4.getText().length());
                }
                if (text.length() == 0){
                    etOTP2.requestFocus();
                    etOTP2.setSelection(etOTP2.getText().length());
                }
                break;
            case R.id.etOTP4:
                if (text.length() == 0){
                    etOTP3.requestFocus();
                    etOTP3.setSelection(etOTP3.getText().length());
                }
                break;
        }
    }
    @Override
    public void beforeTextChanged(CharSequence arg0, int arg1, int arg2, int arg3) {
    }

    @Override
    public void onTextChanged(CharSequence arg0, int arg1, int arg2, int arg3) {
    }
}
