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。

    EditText text = (EditText) findViewById(R.id.editText);

    text.setOnClickListener(new OnClickListener(){
       @RequiresApi(api = Build.VERSION_CODES.N)
       @Override
       public void onClick(View view) {

             DatePickerDialog datePickerDialog = new DatePickerDialog(this, new DatePickerDialog.OnDateSetListener() {
               @Override
               public void onDateSet(DatePicker datePicker, int i, int i1, int i2) {
                   String date = i2 + "/" + (++i1) + "/" + i;
                   text.setText(date);
                }
        },year,month,date);
       }
    });  

    datePickerDialog.show();

您还可以通过这些语句设置最小日期和最大日期。

   datepickerDialoge.getDatepicker().setMinDate(long Date);

   datepickerDialoge.getDatepicker().setMaxDate(long Date);

注意:在datepickerDialog.show()之前添加这些行;声明 你会得到这样的日期=12/2/2017。

我希望我的回答能有所帮助。

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;
            }
        }

使用@DrunkenDaddy扩展函数,至少在我的情况下(以编程方式创建EditText),它在第一次单击时显示键盘,然后在第二次单击时显示日期选择器。

显然,将isFocusable和isFocusableInTouchMode设置为false是无关紧要的,因为第一次点击总是被EditText解释为焦点变化。因此,当EditText获得焦点时,我必须触发单击。现在它像预期的那样工作:第一次点击它直接打开日期选择器,而不是键盘(感谢设置showSoftInputOnFocus为false):

fun EditText.transformIntoDatePicker(context: Context, format: String = "dd/MM/yyyy", maxDate: Date? = null) {
    isClickable = true
    showSoftInputOnFocus = false
    isCursorVisible = false

    setOnFocusChangeListener { _, hasFocus ->  if (hasFocus) callOnClick()}

    val myCalendar = Calendar.getInstance()
    val datePickerOnDataSetListener =
        DatePickerDialog.OnDateSetListener { _, year, monthOfYear, dayOfMonth ->
            myCalendar.set(Calendar.YEAR, year)
            myCalendar.set(Calendar.MONTH, monthOfYear)
            myCalendar.set(Calendar.DAY_OF_MONTH, dayOfMonth)
            val sdf = SimpleDateFormat(format, Locale.getDefault())
            setText(sdf.format(myCalendar.time))
    }

    setOnClickListener {
        DatePickerDialog(
             context, datePickerOnDataSetListener, 
             myCalendar.get(Calendar.YEAR), myCalendar.get(Calendar.MONTH),
             myCalendar.get(Calendar.DAY_OF_MONTH)
        ).run {
            maxDate?.time?.also { datePicker.maxDate = it }
            show()
    }
}

选中的答案不太适合我,因为我必须点击EditText框一次,然后在OnClickListener启动之前再次点击它。我能够通过用OnTouchListener替换OnClickListener来修复这个问题,以防有人遇到类似的问题,下面是我的代码看起来是什么样的:

Calendar myCalendar = 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(Calendar.YEAR, year);
        myCalendar.set(Calendar.MONTH, monthOfYear);
        myCalendar.set(Calendar.DAY_OF_MONTH, dayOfMonth);
        updateLabel();
    }

};
edittext.setOnTouchListener(new View.OnTouchListener() {

    @Override
    public void onTouch(View v, MotionEvent event) {
        if(event.getAction() == MotionEvent.ACTION_DOWN) {
            new DatePickerDialog(classname.this, date, myCalendar
                    .get(Calendar.YEAR), myCalendar.get(Calendar.MONTH),
                    myCalendar.get(Calendar.DAY_OF_MONTH)).show();
        }
    }
});

private void updateLabel() {

    String myFormat = "MM/dd/yy"; //In which you need put here
    SimpleDateFormat sdf = new SimpleDateFormat(myFormat, Locale.US);

    edittext.setText(sdf.format(myCalendar.getTime()));
}
class MyClass implements OnClickListener, OnDateSetListener {   
   EditText editText;
   this.editText = (EditText) findViewById(R.id.editText);
   this.editText.setOnClickListener(this);
   @Override
   public void onClick(View v) {

       DatePickerDialog dialog = new DatePickerDialog(this, this, 2013, 2, 18);
       dialog.show();
   }
   @Override
   public void onDateSet(DatePicker view, int year, int monthOfYear, int dayOfMonth) {
       // this.editText.setText();
   }
}

把这4行放在(EditText, AppCompatEditText)上。它不会显示键盘。然后在clicklistener上,你可以显示datePicker

android:clickable="false" 
   android:cursorVisible="false" 
   android:focusable="false" 
   android:focusableInTouchMode="false"
