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。

XML部分:
<EditText
android:id="@+id/etDOB"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:clickable="true"
android:editable="false"
android:ems="10"
android:hint="Enter Your Date of Birth" />
Java的部分:
final Calendar myCalendar = Calendar.getInstance();
userDOBView = (EditText)findViewById(R.id.etDOB);
final DatePickerDialog.OnDateSetListener date = new DatePickerDialog.OnDateSetListener(){
@Override
public void onDateSet(DatePicker view, int year, int monthOfYear, int dayOfMonth) {
myCalendar.set(Calendar.YEAR, year);
myCalendar.set(Calendar.MONTH, monthOfYear);
myCalendar.set(Calendar.DAY_OF_MONTH, dayOfMonth);
updateLabel();
}
};
userDOBView.setOnTouchListener(new View.OnTouchListener(){
@Override
public boolean onTouch(View v, MotionEvent event){
if(event.getAction() == MotionEvent.ACTION_DOWN){
new DatePickerDialog("YourClassName".this, date,
myCalendar.get(Calendar.YEAR),
myCalendar.get(Calendar.MONTH),
myCalendar.get(Calendar.DAY_OF_MONTH)).show();
}
return true;
}
});
private void updateLabel() {
String myFormat = "MM/dd/yyyy"; //In which you need put here
SimpleDateFormat sdf = new SimpleDateFormat(myFormat, Locale.US);
// edittext.setText(sdf.format(myCalendar.getTime()));
userDOBView.setText(sdf.format(myCalendar.getTime()));

用法:
DatePickerHelper assessmentDueDateHelper = new DatePickerHelper(AssessmentsDetailActivity.this,
(TextView) findViewById(R.id.assessmentDueDateEditText));
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;
}
}
这是我怎么做的:类似于选择的答案，但使用一个静态对话框类，所以它更可重用，也使用onFocusChange而不是onClick。
editText.setOnFocusChangeListener(new View.OnFocusChangeListener() {
@Override
public void onFocusChange(View v, boolean hasFocus) {
if (hasFocus) {
DialogFragment datePickerFragment = new DatePickerFragment() {
@Override
public void onDateSet(DatePicker view, int year, int month, int day) {
Log.d(TAG, "onDateSet");
Calendar c = Calendar.getInstance();
c.set(year, month, day);
editText.setText(df.format(c.getTime()));
nextField.requestFocus(); //moves the focus to something else after dialog is closed
}
};
datePickerFragment.show(getActivity().getSupportFragmentManager(), "datePicker");
}
}
});
datepicker对话框。
public static class DatePickerFragment extends DialogFragment implements DatePickerDialog.OnDateSetListener{
@Override
public Dialog onCreateDialog(Bundle savedInstanceState) {
// Use the current date as the default date in the 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);
// Create a new instance of DatePickerDialog and return it
return new DatePickerDialog(getActivity(), this, year, month, day);
}
@Override
public void onDateSet(DatePicker view, int year, int month, int day) {
//blah
}
}
