我正在尝试在
android中的按钮上实现日期选择器.但是一旦我点击按钮错误弹出.但时间选择器运行良好.这是代码：
mPickDate.setOnClickListener(new View.OnClickListener() { //Assigning onClickListener to Date Button
public void onClick(View v) {
showDialog(DATE_DIALOG_ID);
}
});
pickTime.setOnClickListener(new View.OnClickListener() { //Assigning onClickListener to Time Button
@Override
public void onClick(View v) {
showDialog(TIME_DIALOG_ID);
}
});
}
@Override
protected Dialog onCreateDialog(int id) { //Overriding onCreateDialog()
switch (id) {
case DATE_DIALOG_ID:
return new DatePickerDialog(this,mDateSetListener,mYear,mMonth,mDay);
case TIME_DIALOG_ID:
return new TimePickerDialog(this,mTimeSetListener,mHour,mMin,true);
}
return null;
}
TimePickerDialog.OnTimeSetListener mTimeSetListener = new TimePickerDialog.OnTimeSetListener() { //Defining the TimePickerDialog reference variable
@Override
public void onTimeSet(TimePicker view,int hourOfDay,int minute) {
mHour=hourOfDay;
mMin= minute;
updateTime();
}
};
DatePickerDialog.OnDateSetListener mDateSetListener = //Defining the DatePickerDialog reference variable
new DatePickerDialog.OnDateSetListener() {
public void onDateSet(DatePicker view,int year,int monthOfYear,int dayOfMonth) {
mYear = year;
mMonth = monthOfYear;
mDay = dayOfMonth;
updateDisplay();
}
};
这是logcat：

解决方法
我有同样的问题,但我找到了解决方案.你应该初始化mYear,mDay：
//Init this variables as you wish eg.:
private int mYear = 2010;
private int mMonth = 11;
private int mDay =1;
@Override
protected Dialog onCreateDialog(int id) { //Overriding onCreateDialog()
switch (id) {
case DATE_DIALOG_ID:
return new DatePickerDialog(this,mDay);
case TIME_DIALOG_ID:
return new TimePickerDialog(this,true);
}
return null;
}
