android–DatePickerDialog确定按钮未获取所选日期

概述我有一个简单的DatePickerDialog,打开EditText时打开.选择日期并按OK后,它应显示在同一EditText中.如果我只使用默认对话框,它只创建一个按钮就可以正常工作–好的.我添加了一个取消按钮,问题是它只获取当前日期.这是我的代码：privatevoidshowDatePicker(Stringbirthday

我有一个简单的DatePickerDialog,打开EditText时打开.选择日期并按OK后,它应显示在同一EditText中.如果我只使用默认对话框,它只创建一个按钮就可以正常工作 – 好的.我添加了一个取消按钮,问题是它只获取当前日期.

这是我的代码：

    private voID showDatePicker(String birthdayStr) {        // Todo auto-generated method stub        final Calendar c = Calendar.getInstance();        if (birthdayStr.equals("")) {            yearStr = c.get(Calendar.YEAR);            monthStr = c.get(Calendar.MONTH);            dayStr = c.get(Calendar.DAY_OF_MONTH);        }        DatePickerDialog.OnDateSetListener datePickerListener = new DatePickerDialog.OnDateSetListener() {            // when dialog Box is closed, below method will be called.            public voID onDateSet(DatePicker vIEw, int selectedYear,                    int selectedMonth, int selectedDay) {                if (isOkayClicked) {                    birthday.setText(selectedYear + (selectedMonth + 1) + selectedDay);                    yearStr = selectedYear;                    monthStr = selectedMonth;                    dayStr = selectedDay;                }                isOkayClicked = false;            }        };        DatePickerDialog datePickerDialog = new DatePickerDialog(                RegistrationTwoActivity.this, datePickerListener, yearStr,                monthStr, dayStr);        datePickerDialog.setbutton(DialogInterface.button_NEGATIVE,                getString(R.string.cancel),                new DialogInterface.OnClickListener() {                    public voID onClick(DialogInterface dialog, int which) {                        if (which == DialogInterface.button_NEGATIVE) {                            dialog.cancel();                            isOkayClicked = false;                        }                    }                });        datePickerDialog.setbutton(DialogInterface.button_POSITIVE, "OK",                new DialogInterface.OnClickListener() {                    public voID onClick(DialogInterface dialog, int which) {                        if (which == DialogInterface.button_POSITIVE) {                            isOkayClicked = true;                            birthday.setText(selectedYear + (selectedMonth + 1) + selectedDay);                        }                    }                });        datePickerDialog.setCancelable(false);        datePickerDialog.show();    }@H_419_9@
如果我删除了birthday.setText行(selectedYear(selectedMonth 1)selectedDay);在OK或button_POSITIVE下,它工作正常.但是在某些设备上,它没有将所选日期设置为EditText,因为它只在datePickerListener中调用.所以我决定添加行birthday.setText(selectedYear(selectedMonth 1)selectedDay);在OK或button_POSITIVE下但现在的问题是它只获取当前日期.
我有点困惑.如果有人可以帮助我.
解决方法:
在代码中进行以下更改
final DatePickerDialog.OnDateSetListener datePickerListener = new DatePickerDialog.OnDateSetListener() {                    // when dialog Box is closed, below method will be called.                    public voID onDateSet(DatePicker vIEw, int selectedYear,                            int selectedMonth, int selectedDay) {                        if (isOkayClicked) {                            birthday.setText(selectedYear + (selectedMonth + 1)                                    + selectedDay);                            yearStr = selectedYear;                            monthStr = selectedMonth;                            dayStr = selectedDay;                        }                        isOkayClicked = false;                    }                };                final DatePickerDialog datePickerDialog = new DatePickerDialog(                        RegistrationTwoActivity.this, datePickerListener,                        yearStr, monthStr, dayStr);                datePickerDialog.setbutton(DialogInterface.button_NEGATIVE,                        getString(R.string.cancel),                        new DialogInterface.OnClickListener() {                            public voID onClick(DialogInterface dialog,                                    int which) {                                if (which == DialogInterface.button_NEGATIVE) {                                    dialog.cancel();                                    isOkayClicked = false;                                }                            }                        });                datePickerDialog.setbutton(DialogInterface.button_POSITIVE,                        "OK", new DialogInterface.OnClickListener() {                            public voID onClick(DialogInterface dialog,                                    int which) {                                if (which == DialogInterface.button_POSITIVE) {                                    isOkayClicked = true;                                    DatePicker datePicker = datePickerDialog                                            .getDatePicker();                                    datePickerListener.onDateSet(datePicker,                                            datePicker.getYear(),                                            datePicker.getMonth(),                                            datePicker.getDayOfMonth());                                }                            }                        });                datePickerDialog.setCancelable(false);                datePickerDialog.show();@H_419_9@
要使用此代码,您应该在Manifest中将minSdkVersion更改为至少11.希望对你有帮助.. ：)
