EditText to have only numbers and hide input value

Question

What I want is the EditText to accept only one input value which is a number and to have password attribute. I also want, if I enter value, say in first EditText, I should focus to next EditText. Similarly, if I press delete button of softkeyboard, its focus should go backwards like say, from EditText2 to EditText 1. Mix all these and password attribute doesn't work properly. And don't downvote without actually trying out the code.

This is the layout I have right now.

                pinc_6.clearFocus();
                InputMethodManager inputManager =
                        (InputMethodManager) getActivity().
                                getSystemService(Context.INPUT_METHOD_SERVICE);
                inputManager.hideSoftInputFromWindow(
                        getActivity().getCurrentFocus().getWindowToken(),
                        InputMethodManager.HIDE_NOT_ALWAYS);
            } else {

                pinc_6.clearFocus();
                pinc_5.requestFocus();
                pinc_5.setCursorVisible(true);

        }

        public void beforeTextChanged(CharSequence s, int start, int count,
                                      int after) {

        }

        public void afterTextChanged(Editable s) {

        }
    });

I have also tried this way::

    pinc_2.setFilters(new InputFilter[]{back_filter_pin2, new InputFilter.LengthFilter(1)});
InputFilter back_filter_pin2 = new InputFilter() {
        public CharSequence filter(CharSequence source, int start, int end, Spanned dest, int dstart, int dend) {

            if (end == 0) {
                pinc_1.requestFocus();
            } else if (end == 1) {
                pinc_2.clearFocus();
                pinc_3.requestFocus();

            }

            return source;
        }
    };

Also have tried:

  pinc_6.setInputType(InputType.TYPE_CLASS_NUMBER |
  InputType.TYPE_NUMBER_VARIATION_PASSWORD);

Answer 1

First of all use your condition inside

public void afterTextChanged(Editable s) {

}

To focus your cursor to previous field when delete text you can check length with 0 like this ...

 if (pinc_2.length() == 1) {
    pinc_2.clearFocus();
    pinc_3.requestFocus();
    pinc_3.setCursorVisible(true);
 } else if (pinc_2.length() == 0) {
    pinc_2.clearFocus();
    pinc_1.requestFocus();
    pinc_1.setCursorVisible(true);
 } 

I tested it ... it will work... Enjoy coding :)

Edit

Complete code for all EditText

I little bet add something for 6th EditText see that..

pinc_1.addTextChangedListener(new TextWatcher() {
        public void onTextChanged(CharSequence s, int start, int before, int count) {

        }

        public void beforeTextChanged(CharSequence s, int start, int count,int after) {
        }

        public void afterTextChanged(Editable s) {
            if (s.length() == 1) {
                pinc_1.clearFocus();
                pinc_2.requestFocus();
                pinc_2.setCursorVisible(true);
            } else {

            }
        }
    });

    pinc_2.addTextChangedListener(new TextWatcher() {

                pinc_3.setCursorVisible(true);
