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;
            }
        }

我已经尝试了所有建议的方法，但它们都有各自的问题。

在我看来，最好的解决方案是使用如下的框架布局:

<FrameLayout
            android:layout_width="match_parent"
            android:layout_height="wrap_content" >

            <EditText
                android:layout_width="match_parent"
                android:layout_height="wrap_content"
                .... />

            <View
                android:id="@+id/invisible_click_watcher"
                android:layout_width="match_parent"
                android:layout_height="match_parent"
                android:clickable="true" />

</FrameLayout>

然后添加DatePickerDialog代码，这个代码在@Android的回答中写得很漂亮。

在XML文件中试试这个:

<EditText
    android:id="@+id/Birthday"
    custom:font="@string/font_avenir_book"
    android:clickable="false" 
    android:cursorVisible="false" 
    android:focusable="false" 
    android:focusableInTouchMode="false"
    android:hint="@string/birthday"/>

在Java文件中是这样的:

public class MainActivity extends AppCompatActivity {
    final Calendar myCalendar= Calendar.getInstance();
    EditText editText;
    
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        editText=(EditText) findViewById(R.id.BirthDate);
        DatePickerDialog.OnDateSetListener date =new DatePickerDialog.OnDateSetListener() {
            @Override
            public void onDateSet(DatePicker view, int year, int month, int day) {
                myCalendar.set(Calendar.YEAR, year);
                myCalendar.set(Calendar.MONTH,month);
                myCalendar.set(Calendar.DAY_OF_MONTH,day);
                updateLabel();
            }
        };
        editText.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View view) {
                new DatePickerDialog(MainActivity.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";
        SimpleDateFormat dateFormat=new SimpleDateFormat(myFormat, Locale.US);
        editText.setText(dateFormat.format(myCalendar.getTime()));
    }
}

在EditText的xml文件中添加android:focusable="false"以允许单个触摸。

试试这个

btn=(Button)findViewById(R.id.chs);
    final Dialog dialog = new Dialog(MainActivity.this);
    dialog.setCanceledOnTouchOutside(true);
    btn.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            dialog.setContentView(R.layout.datepickerdialog);
            dp=(DatePicker) dialog.findViewById(R.id.btp);
            dialog.show();
            ok=(Button)dialog.findViewById(R.id.btn1);
            ok.setOnClickListener(new View.OnClickListener() {
                @Override
                public void onClick(View v) {
                    dialog.dismiss();
                }
            });
        }

    });

下面是一个针对懒人的Kotlin扩展函数:

fun EditText.transformIntoDatePicker(context: Context, format: String, maxDate: Date? = null) {
    isFocusableInTouchMode = false
    isClickable = true
    isFocusable = false

    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.UK)
            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()
        }
    }
}

用法:

在活动:

editText.transformIntoDatePicker(this, "MM/dd/yyyy")
editText.transformIntoDatePicker(this, "MM/dd/yyyy", Date())

在片段:

editText.transformIntoDatePicker(requireContext(), "MM/dd/yyyy")
editText.transformIntoDatePicker(requireContext(), "MM/dd/yyyy", Date())

                Calendar c=Calendar.getInstance();
                Integer month=c.get(Calendar.MONTH);
                Integer day=c.get(Calendar.DAY_OF_MONTH);
                Integer year=c.get(Calendar.YEAR);

                DatePickerDialog datePickerDialog =new DatePickerDialog(Expenture_Activity.this, new DatePickerDialog.OnDateSetListener() {
                    @Override
                    public void onDateSet(DatePicker view, int year, int month, int dayOfMonth) {
                        et_from.setText(dayOfMonth+"/"+month+"/"+year);
                    }
                },year,month,day);
                datePickerDialog.show();
