我正在使用 API 级别 10，我不想仅使用支持库来实现 DatePicker，因此我使用以下方法来创建日期对话框。我以前使用过一个 DatePicker，它工作得很好。我只是看不出这里有什么问题。
我有两个日期对话框来选择各个 OnClickListeners 调用的日期。有人可以帮忙吗？谢谢你。
// 这是在 onCreate
ImageView fromCalendar = (ImageView) findViewById(R.id.from_calendar);
ImageView toCalendar = (ImageView) findViewById(R.id.to_calendar);
fromCalendar.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
showDialog(FROM_DATE_DIALOG);
}
});
toCalendar.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
showDialog(TO_DATE_DIALOG);
}
});
private DatePickerDialog.OnDateSetListener toDateSetListener = new DatePickerDialog.OnDateSetListener() {
public void onDateSet(DatePicker view, int year, int monthOfYear,
int dayOfMonth) {
mYear = year;
mMonth = monthOfYear;
mDay = dayOfMonth;
Log.e("mYear", "" + year + " mMonth:" + mMonth + " mDay" + mDay);
String date = updateDisplay(true);
toDate.setText(date);
}
};
//在onCreate之外
private DatePickerDialog.OnDateSetListener fromDateSetListener = new DatePickerDialog.OnDateSetListener() {
public void onDateSet(DatePicker view, int year, int monthOfYear,
int dayOfMonth) {
mYear = year;
mMonth = monthOfYear;
mDay = dayOfMonth;
Log.e("mYear", "" + year + " mMonth:" + mMonth + " mDay" + mDay);
String date = updateDisplay(true);
fromDate.setText(date);
}
};
protected Dialog onCreateDialog(int id) {
switch(id) {
case FROM_DATE_DIALOG:
Log.e("onCreateDialog::mYear", "" + mYear + " mMonth:" + mMonth
+ " mDay" + mDay);
return new DatePickerDialog(this, fromDateSetListener, mYear, mMonth,
mDay);
case TO_DATE_DIALOG:
Log.e("onCreateDialog::mYear", "" + mYear + " mMonth:" + mMonth
+ " mDay" + mDay);
return new DatePickerDialog(this, toDateSetListener, mYear, mMonth,
mDay);
}
return null;
}
