我有相同形式的日期和时间字段。所以我需要为这些领域选择四个日期和时间。目前我能够得到它,但是当我从第一个选择器中选择时间和日期时,所有字段都显示相同的时间和日期,并且所有字段都已设置。
我使用了几种方法,一些是检查每个字段的视图ID,给对话框提供id并在onCreateDialog方法中使用switch等等。但是没有什么对我有用。请建议我如何实现这一目标。
我的DatePicker代码:
public void showDatePicker() {
DatePickerFragment date1 = new DatePickerFragment();
/**
* Set Up Current Date Into dialog
*/
Calendar calender = Calendar.getInstance();
Bundle args = new Bundle();
args.putInt("year", calender.get(Calendar.YEAR));
args.putInt("month", calender.get(Calendar.MONTH));
args.putInt("day", calender.get(Calendar.DAY_OF_MONTH));
date1.setArguments(args);
/**
* Set Call back to capture selected date
*/
date1.setCallBack(ondate);
date1.show(getSupportFragmentManager(), "Date Picker");
}
DatePickerDialog.OnDateSetListener ondate = new DatePickerDialog.OnDateSetListener() {
public void onDateSet(DatePicker view, int year, int monthOfYear,
int dayOfMonth) {
date.setText(String.valueOf(dayOfMonth) + "-" + String.valueOf(monthOfYear + 1)
+ "-" + String.valueOf(year));
dateValue = date.getText().toString();
est_compDate.setText(String.valueOf(dayOfMonth) + "-" + String.valueOf(monthOfYear + 1)
+ "-" + String.valueOf(year));
estValue = est_compDate.getText().toString();
act_compDate.setText(String.valueOf(dayOfMonth) + "-" + String.valueOf(monthOfYear + 1)
+ "-" + String.valueOf(year));
actValue = act_compDate.getText().toString();
notify_date.setText(String.valueOf(dayOfMonth) + "-" + String.valueOf(monthOfYear + 1)
+ "-" + String.valueOf(year));
notifyValue = notify_date.getText().toString();
}
};
我的DatePickerFragment代码:
public class DatePickerFragment extends DialogFragment {
DatePickerDialog.OnDateSetListener ondateSet;
public DatePickerFragment() {
}
public void setCallBack(DatePickerDialog.OnDateSetListener ondate) {
ondateSet = ondate;
}
private int year, month, day;
@Override
public void setArguments(Bundle args) {
super.setArguments(args);
year = args.getInt("year");
month = args.getInt("month");
day = args.getInt("day");
}
@Override
public Dialog onCreateDialog(Bundle savedInstanceState) {
return new DatePickerDialog(getActivity(), ondateSet, year, month, day);
}
}
因此,当我为date.setText行选择时间和日期选择器时,所有其他三个都在一次设置。
我使用onClick方法调用picker方法:
public void datePicker(View view){
showDatePicker();
}
请让我知道可以做些什么。如果您需要更多信息,请告诉我。提前谢谢。

更新: 在DialogFragment中创建一个接口,并在其中放入一个抽象方法,该方法将在参数中以字符串形式保存日期。然后在您的主活动中实现此接口,并在您的活动中覆盖DateInString(String)方法,该方法将为您提供活动中的选定日期。然后您可以将其显示在您想要的位置。 我正在向您展示一个工作代码,我必须在两个地方设置日期,您可以通过修改活动中的DateInString(String)覆盖方法多次使用它...
DialogFragment:
public class Date extends android.support.v4.app.DialogFragment implements DatePickerDialog.OnDateSetListener {
DatePickerData datePickerData ;
String date = null;
@Override
public Dialog onCreateDialog(Bundle savedInstanceState) {
Calendar cal = Calendar.getInstance();
int year = cal.get(Calendar.YEAR);
byte month = (byte)cal.get(Calendar.MONTH);
byte day = (byte ) cal.get(Calendar.DAY_OF_MONTH);
return new DatePickerDialog(getActivity(),this,year,month,day);
}
@Override
public void onDateSet(DatePicker datePicker, int selectedYear, int selectedMonth, int selectedDay) {
Calendar cal = Calendar.getInstance();
cal.set(selectedYear,selectedMonth,selectedDay);
SimpleDateFormat dateFormat = new SimpleDateFormat("dd/MM/yyyy");
date = dateFormat.format(cal.getTime());
passDate(date);
}
@Override
public void onAttach(Activity activity) {
super.onAttach(activity);
datePickerData = (DatePickerData)activity;
}
public void passDate(String date){
datePickerData.DateInString(date);
public interface DatePickerData{
public void DateInString(String date);
}
}
和你的活动:
public class ActMarkAttendance extends FragmentActivity implements Date.DatePickerData{
private boolean isStartDate = false;
private TextView startDateTextView;
private TextView endDateTextView;
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_act_view_attendance);
startDateTextView = (TextView) findViewById(R.id.startDateTextView_attView);
endDateTextView = (TextView) findViewById(R.id.endDateTextView_attView);
startDateTextView.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View view) {
isStartDate = true;
showDateFragment();
}
});
endDateTextView.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View view) {
isStartDate = false;
showDateFragment();
}
});
}
private void showDateFragment(){
Date dateFragment = new Date();
dateFragment.show(fm,General.NOTHING);
}
@Override
public void DateInString(String date) {
if (isStartDate)
startDateViewer.setText(date);
else
endDateViewer.setText(date);
}
}
