将字符串从ClassA移动到Android上的Calendar中的B类

Question

我尝试了几种方法，但是没有方法可以解决我的代码问题。无论如何，这是我在classA上的onclick代码。

public void onClick(View view)
{
    String date_month_year = (String) view.getTag();
    selectedDayMonthYearButton.setText("Selected: " + date_month_year);

    try
    {
        // comment added by SO: enter code here
        Date parsedDate = dateFormatter.parse(date_month_year);
        Log.d(tag, "Parsed Date: " + parsedDate.toString());
    }
    catch (ParseException e)
    {
        e.printStackTrace();
    }

    switch(view.getId())
    {
        case R.id.button1:
            Intent i = new Intent(DatabaseSample.this, SaveData.class);  
            startActivity(i);
            break;

    }
}

    public int getCurrentDayOfMonth()
    {
        return currentDayOfMonth;
    }

    private void setCurrentDayOfMonth(int currentDayOfMonth)
    {
            this.currentDayOfMonth = currentDayOfMonth;
    }
    public void setCurrentWeekDay(int currentWeekDay)
    {
            this.currentWeekDay = currentWeekDay;
    }
    public int getCurrentWeekDay()
    {
            return currentWeekDay;
    }
}
}

我想将字符串 date_month_year 移动到另一个类并显示它。这是我的B类代码。我想知道字符串的读取位置以及如何从A类到B类。 当用户点击其中一个日期时，字符串date_month_year将是年份和月份的日期，即12/12/2012我想复制该字符串并在CLASS B中显示 *

            this.dh = new DataManipulator(this);
            this.dh.insert(myEditText1,myEditText2,myEditText3,myEditText4);

            showDialog(DIALOG_ID);
            break;

        }
    }  
    protected final Dialog onCreateDialog(final int id) {
        Dialog dialog = null;
        switch(id) {
        case DIALOG_ID:

            builder.setMessage("Information saved successfully ! Add Another Info?")
            .setCancelable(false)
            .setPositiveButton("No", new DialogInterface.OnClickListener() {
                public void onClick(DialogInterface dialog, int id) {
                    SaveData.this.finish();

              }
            })

                    dialog.cancel();
                }
            });
            AlertDialog alert = builder.create(); 
            dialog = alert;
            break;

        default:

        }
        return dialog;
    }
