增加数字输入框的单独监听

由于很多人要求监听数字变化，于是增加了数字输入框的监听事件
numberPickerView.setOnInputNumberListener(new NumberPickerView.OnInputNumberListener() {
@OverRide
public void beforeTextChanged(CharSequence s, int start, int count, int after) {

        }

        @Override
        public void onTextChanged(CharSequence charSequence, int start, int before, int count) {

        }

        @Override
        public void afterTextChanged(Editable editable) {
            Log.d("MainActivity",editable.toString());
        }
    });
