Answer 1

This worked for my case, also max_length of edit text should be 1.

otp_1.addTextChangedListener(new TextWatcher() {
                @Override
                public void beforeTextChanged(CharSequence charSequence, int i, int i1, int i2) {
                    //
                }

            @Override
            public void onTextChanged(CharSequence charSequence, int i, int i1, int i2) {

            }

            @Override
            public void afterTextChanged(Editable editable) {
                //
                if(editable.length()>0){
                    otp_1.clearFocus();
                    otp_2.requestFocus();
                    otp_2.setCursorVisible(true);
                }
            }
        });

        otp_2.addTextChangedListener(new TextWatcher() {
            @Override
            public void beforeTextChanged(CharSequence charSequence, int i, int i1, int i2) {
                //
            }

            @Override
            public void onTextChanged(CharSequence charSequence, int i, int i1, int i2) {

            }

            @Override
            public void afterTextChanged(Editable editable) {
                //
                if(editable.length() > 0) {
                    otp_2.clearFocus();
                    otp_3.requestFocus();
                    otp_3.setCursorVisible(true);
                }
            }
        });

        otp_3.addTextChangedListener(new TextWatcher() {
            @Override
            public void beforeTextChanged(CharSequence charSequence, int i, int i1, int i2) {
                //
            }

            @Override
            public void onTextChanged(CharSequence charSequence, int i, int i1, int i2) {

            }

            @Override
            public void afterTextChanged(Editable editable) {
                if(editable.length() > 0) {
                    otp_3.clearFocus();
                    otp_4.requestFocus();
                    otp_4.setCursorVisible(true);
                }
            }
        });
