Datepicker:如何在点击编辑文本时弹出Datepicker

我想显示日期选择器弹出窗口。我找到了一些例子，但我没有得到正确的。我有一个edittext，我希望当我点击edittext时，datepicker对话框应该弹出，设置日期后，日期应该显示在edittext在dd/mm/yyyy格式。请为我提供示例代码或良好的链接。

使用片段、MvvmCross和Xamarin的解决方案。安卓

public class EnterTimeView : MvxFragment, DatePickerDialog.IOnDateSetListener
    {            
        private EditText datePickerText;
        public EnterTimeView()
        {
            this.RetainInstance = true;
        }

        public override Android.Views.View OnCreateView(Android.Views.LayoutInflater inflater, Android.Views.ViewGroup container, Android.OS.Bundle savedInstanceState)
        {
            this.HasOptionsMenu = true;

            var ignored = base.OnCreateView(inflater, container, savedInstanceState);
            var view = inflater.Inflate(Resource.Layout.EnterTimeView, container, false);

            datePickerText = view.FindViewById<EditText>(Resource.Id.DatePickerEditText);
            datePickerText.Focusable = false;
            datePickerText.Click += delegate
            {
                var dialog = new DatePickerDialogFragment(Activity, Convert.ToDateTime(datePickerText.Text), this);
                dialog.Show(FragmentManager, "date");
            };

            var set = this.CreateBindingSet<EnterTimeView, EnterTimeViewModel>();    
            set.Bind(datePickerText).To(vm => vm.Date);
            set.Apply();

            return view;
        }   

        public void OnDateSet(Android.Widget.DatePicker view, int year, int monthOfYear, int dayOfMonth)
        {
            datePickerText.Text = new DateTime(year, monthOfYear + 1, dayOfMonth).ToString();
        }

        private class DatePickerDialogFragment : Android.Support.V4.App.DialogFragment 
        {
            private readonly Context _context;
            private DateTime _date;
            private readonly DatePickerDialog.IOnDateSetListener _listener;

            public DatePickerDialogFragment(Context context, DateTime date, DatePickerDialog.IOnDateSetListener listener)
            {
                _context = context;
                _date = date;
                _listener = listener;
            }

            public override Dialog OnCreateDialog(Bundle savedState)
            {
                var dialog = new DatePickerDialog(_context, _listener, _date.Year, _date.Month - 1, _date.Day);
                return dialog;
            }
        }

试试这个:

public class DatePickerFragment extends DialogFragment implements DatePickerDialog.OnDateSetListener {

DataPickerListener listener;

public DatePickerFragment(DataPickerListener l) {
    listener = l;
}

@Override
public Dialog onCreateDialog(Bundle savedInstanceState) {
    // Use the current date as the default date in the date picker
    final Calendar c = Calendar.getInstance();
    int year = c.get(Calendar.YEAR);
    int month = c.get(Calendar.MONTH);
    int day = c.get(Calendar.DAY_OF_MONTH);

    return new DatePickerDialog(getActivity(),
            AlertDialog.THEME_HOLO_LIGHT, this, year, month, day);
}

public void onDateSet(DatePicker view, int year, int month, int day) {

    month = month + 1;
    String stringOfDate = day + "-" + month + "-" + year;
    listener.setDate(stringOfDate);
    Util.Log(stringOfDate);
}

@Override
public void onCancel(DialogInterface dialog) {
    // TODO Auto-generated method stub
    super.onCancel(dialog);
    listener.cancel();
}

public static interface DataPickerListener {
    void setDate(String date);

    void cancel();
}
}
// use this function to open datePicker popup

DialogFragment newFragment;

public void pickDate() {
    if (newFragment == null)
        newFragment = new DatePickerFragment(new PickDateListener());
    newFragment.show(getFragmentManager(), "Date Picker");
}

class PickDateListener implements DataPickerListener {

    @Override
    public void setDate(String date) {
        createSpiner(date);
        onetouch = false;
    }

    @Override
    public void cancel() {
        onetouch = false;
    }

}

如果你需要一个单一的功能，所有的活动，当调用将打开日期选择器，然后返回我选择的日期，然后为所有创建一个接口

public interface OnDatePickerLitionarCallBack {

    void DatePicker(String selectedDate);
}

然后在活动中调用接口

 public class MapsActivity extends FragmentActivity implements OnDatePickerLitionarCallBack {
     @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_maps);

        findViewById(R.id.date_pick).setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View view) {
                date_Picker(MapsActivity.this,MapsActivity.this);
            }
        });
    }
     @Override
        public void DatePicker(String selectedDate) {
        
    
        }
    }

实现接口后，创建一个公共类用于访问任何活动或片段

public class Commons{

    public static void date_Picker(Context context, OnDatePickerLitionarCallBack onDatePickerLitionarCallBack) {
        final java.util.Calendar myCalendar = java.util.Calendar.getInstance();

        DatePickerDialog.OnDateSetListener date = new DatePickerDialog.OnDateSetListener() {

            @Override
            public void onDateSet(DatePicker view, int year, int monthOfYear,
                                  int dayOfMonth) {
                // TODO Auto-generated method stub
                myCalendar.set(java.util.Calendar.YEAR, year);
                myCalendar.set(java.util.Calendar.MONTH, monthOfYear);
                myCalendar.set(java.util.Calendar.DAY_OF_MONTH, dayOfMonth);
                String myFormat = "dd,MMM yyyy"; //In which you need put here
                java.text.SimpleDateFormat sdf = new java.text.SimpleDateFormat(myFormat, Locale.US);
   
                onDatePickerLitionarCallBack.DatePicker(sdf.format(myCalendar.getTime()));

            }
        };
        DatePickerDialog datePickerDialog = new DatePickerDialog(context, date, myCalendar
                .get(java.util.Calendar.YEAR), myCalendar.get(java.util.Calendar.MONTH),
                myCalendar.get(java.util.Calendar.DAY_OF_MONTH));


        datePickerDialog.show();

    }
}
