我正在使用日期选择器对话框。它在 kitkat 上运行正常，但是当我在棒棒糖上运行应用程序时，当我单击编辑文本时，它会打开一个日期选择器对话框，但当我选择日期时，它会不幸地给出停止错误。以下是 edittext 上日期选择器的代码。
private void setDateTimeField() {
fromLabel.setOnClickListener(this);
toLabel.setOnClickListener(this);
final DateFormat dateFormat = new SimpleDateFormat("dd-MM-yyyy"); //yyyy/MM/dd HH:mm:ss
final Date date = new Date();
final String u = dateFormat.format(date);
Calendar newCalendar = Calendar.getInstance();
fromDatePickerDialog = new DatePickerDialog(this, new OnDateSetListener() {
public void onDateSet(DatePicker view, int year, int monthOfYear, int dayOfMonth) {
Calendar newDate = Calendar.getInstance();
newDate.set(year, monthOfYear, dayOfMonth);
from1 = dateFormatter.format(newDate.getTime());
diff1 = newDate.getTimeInMillis();
long d = date.getTime();
if((newDate.getTime()).equals(date)||(newDate.getTime()).after(date)){
long d1 = (diff1 / (24 * 60 * 60 * 1000) - d / (24 * 60 * 60 * 1000)) + 1;
if(d1>30){
total.setVisibility(View.VISIBLE);
total.setText("Booking not allowed as the Date given is outside Advance Booking Period");
avail.setVisibility(View.GONE);
}
else{
total.setVisibility(View.GONE);
fromLabel.setText(from1);
toLabel.setText(null);
to=null;
avail.setVisibility(View.GONE);
from=fromLabel.getText().toString();
}
}
else{
total.setVisibility(View.VISIBLE);
total.setText("Choose date after or equals to current date");
fromLabel.setText("");
toLabel.setText(null);
from=null;
to=null;
}
}
},newCalendar.get(Calendar.YEAR), newCalendar.get(Calendar.MONTH), newCalendar.get(Calendar.DAY_OF_MONTH));
fromDatePickerDialog.setButton(DialogInterface.BUTTON_POSITIVE, getString(R.string.Done), new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int which) {
if (which == DialogInterface.BUTTON_POSITIVE) {
dialog.cancel();
if(type.equals("According to time"))
{
int cnt=-1;
if(from1.equals(u)){
cnt = 1;
loadTimeSpinnerDataATT(text,from,cnt);
}
else if(total.getText()=="Choose date after or equals to current date")
{
}
else if(total.getText()=="Booking not allowed as the Date given is outside Advance Booking Period")
{
}
else
{cnt = 0;
loadTimeSpinnerDataATT(text,from,cnt);
}
}
}
}
});
}
public void onClick(View view) {
if(view == fromLabel) {
fromDatePickerDialog.show();
} else if(view == toLabel) {
toDatePickerDialog.show();
}
}
public void onClose(DialogInterface dialogInterface)
{
}
}
