我有一个简单的 DatePickerDialog
,它会在打开 EditText
时打开。选择日期并按 OK 后,它应该显示在相同的 EditText
。如果我只使用它只创建一个按钮的默认对话框,它就可以正常工作 - 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 OK 或 BUTTON_POSITIVE 下的
birthday.setText(selectedYear + (selectedMonth + 1) + selectedDay);
行,它工作正常。但在某些设备上,它不会将所选日期设置为 EditText
,因为它仅在 datePickerListener
内部调用。所以我决定在 OK 或 BUTTON_POSITIVE 下添加 birthday.setText(selectedYear + (selectedMonth + 1) + selectedDay);
行,但现在的问题是它只获取当前日期。我对此有点困惑。如果有人可以帮助我。
最佳答案
在您的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。希望能帮到你.. :)
