使用数据绑定:

<EditText
  android:layout_width="wrap_content"
  android:layout_height="wrap_content"
  android:focusable="false"
  android:onClick="@{() -> viewModel.onDateEditTextClicked()}"
  android:hint="@string/hint_date"
  android:imeOptions="actionDone"
  android:inputType="none"
  android:maxLines="1"
  android:text="@={viewModel.filterDate}" />

(参见focusable, inputType和onClick)

在视图模型:

public void onDateEditTextClicked() {
    // do something
}

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。

我认为最好重写EditText类…

public class EditTextDP extends android.support.v7.widget.AppCompatEditText implements View.OnClickListener, DatePickerDialog.OnDateSetListener {
    public EditTextDP(Context context) {
        super(context);
        setOnClickListener(this);
        setFocusable(false);
    }

    public EditTextDP(Context context, AttributeSet attrs) {
        super(context, attrs);
        setOnClickListener(this);
        setFocusable(false);
    }

    public EditTextDP(Context context, AttributeSet attrs, int defStyleAttr) {
        super(context, attrs, defStyleAttr);
        setOnClickListener(this);
        setFocusable(false);
    }

    @Override
    public void onDateSet(DatePicker view, int year, int monthOfYear, int dayOfMonth) {
        setText(new StringBuilder().append(dayOfMonth).append("/").append(monthOfYear + 1).append("/").append(year));
    }

    @Override
    public void onClick(View v) {
        Calendar calendar = Calendar.getInstance(TimeZone.getDefault());
        DatePickerDialog dialog = new DatePickerDialog(getContext(), this, calendar.get(Calendar.YEAR), calendar.get(Calendar.MONTH), calendar.get(Calendar.DAY_OF_MONTH));
        dialog.show();
    }
}

然后在XML中使用它…

            <*.*.*.EditTextDP
                android:id="@+id/c1_dob_hm"
                android:layout_width="match_parent"
                android:layout_height="wrap_content"
                android:background="@drawable/round_edittext_white"
                android:ems="10"
                android:padding="8dp">

            </*.*.*.EditTextDP>

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;
            }
        }

用这个简单的技巧来做吧:

步骤1:创建一个片段对话框

public class DatePickerFragmentDialog  extends DialogFragment {

    @Override
    public Dialog onCreateDialog(Bundle savedInstanceState) {
        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(), (DatePickerDialog.OnDateSetListener) getActivity(), year, month, day);
    }

}

第二步:在必要的活动中遵循这一点

该活动必须实现:DatePickerDialog。OnDateSetListener 在按钮上设置onClickListener: DialogFragment datePicker = new DatePickerFragmentDialog(); datePicker.show(getSupportFragmentManager()， "自定义日期选择器");

步骤3:覆盖OnDateSetListener

public void onDateSet(DatePicker view, int year, int month, int dayOfMonth) {
        Calendar calendar = Calendar.getInstance();
        calendar.set(Calendar.YEAR, year);
        calendar.set(Calendar.MONTH, month);
        calendar.set(Calendar.DAY_OF_MONTH, dayOfMonth);

        @SuppressLint("SimpleDateFormat") DateFormat dateFormat = new 
        SimpleDateFormat("MM/dd/yyyy");
        String currentDateString = dateFormat.format(calendar.getTime());

        tvPaymentDate.setText(currentDateString);
    }

因此，我们可以使用任何格式的日期:)

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()
    }
}
