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();
}
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();
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.. :)
