android中的当前日期设置显示额外一个月

Question

我想在Activity（默认设置）中设置当前日期，用户可以通过单击日期选择器来配置日期。但有些设备显示额外一个月，日期选择器对话框也显示一个月额外。能帮我解决这个问题吗

public void setCurrentDateOnButton()
{
    Log.d(LogActivityTagNames.SCHEDULE_ACTIVITY," Entered into setCurrentDateOnButton()");
    final Calendar c = Calendar.getInstance();
    myear = c.get(Calendar.YEAR);
    mmonth = c.get(Calendar.MONTH)+1;
    mday = c.get(Calendar.DAY_OF_MONTH);
    String month  = QuickeRideAppUtils.formatDateTime(mmonth); 
    String day = QuickeRideAppUtils.formatDateTime(mday);
    date.setText(new StringBuilder()
    .append(day).append("-").append(month).append("-")
    .append(myear).append(" "));
}

...

private DatePickerDialog.OnDateSetListener datePickerListener = new DatePickerDialog.OnDateSetListener()
{
    public void onDateSet(DatePicker view, int selectedYear,int selectedMonth, int selectedDay)
    {
        myear = selectedYear;
        mmonth = selectedMonth;
        mday = selectedDay;
        String month  = QuickeRideAppUtils.formatDateTime(mmonth);
        String day = QuickeRideAppUtils.formatDateTime(mday);
        date.setText(new StringBuilder().append(day).append("-").append(month).append("-").append(myear).append(" "));    

    }
};

从此行mmonth = c.get(Calendar.MONTH)+1;删除+1只需将其写为

  

mmonth = c.get(Calendar.MONTH)

date.setText(new StringBuilder()
    .append(day).append("-").append(month).append("-")
    .append(myear).append(" "));
