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())

还有另一种更好的可重用方式:

创建一个类:

class setDate implements OnFocusChangeListener, OnDateSetListener {   

       private EditText editText;
       private Calendar myCalendar;

       public setDate(EditText editText, Context ctx){
           this.editText = editText;
           this.editText.setOnFocusChangeListener(this);
           myCalendar = Calendar.getInstance();
       }

       @Override
       public void onDateSet(DatePicker view, int year, int monthOfYear, int dayOfMonth)     {
           // this.editText.setText();

            String myFormat = "MMM dd, yyyy"; //In which you need put here
            SimpleDateFormat sdformat = new SimpleDateFormat(myFormat, Locale.US);
            myCalendar.set(Calendar.YEAR, year);
            myCalendar.set(Calendar.MONTH, monthOfYear);
            myCalendar.set(Calendar.DAY_OF_MONTH, dayOfMonth);

            editText.setText(sdformat.format(myCalendar.getTime()));

       }

        @Override
        public void onFocusChange(View v, boolean hasFocus) {
            // TODO Auto-generated method stub
            if(hasFocus){
             new DatePickerDialog(ctx, this, myCalendar
                       .get(Calendar.YEAR), myCalendar.get(Calendar.MONTH),
                       myCalendar.get(Calendar.DAY_OF_MONTH)).show();
            }
        }

    }

然后在onCreate函数下调用这个类:

    EditText editTextFromDate = (EditText) findViewById(R.id.editTextFromDate);
    setDate fromDate = new setDate(editTextFromDate, this);

editText。setOnClickListener(new View.OnClickListener() {

    @Override
    public void onClick(final View v) {
        final Calendar c = Calendar.getInstance();
        mYear = c.get(Calendar.YEAR);
        mMonth = c.get(Calendar.MONTH);
        mDay = c.get(Calendar.DAY_OF_MONTH);


        final DatePickerDialog datePickerDialog = new DatePickerDialog(getContext(),
                new DatePickerDialog.OnDateSetListener() {
                    String fmonth, fDate;
                    int month;


                    @Override
                    public void onDateSet(DatePicker view, int year,
                                          int monthOfYear, int dayOfMonth) {


                        try {
                            if (monthOfYear < 10 && dayOfMonth < 10) {

                                fmonth = "0" + monthOfYear;
                                month = Integer.parseInt(fmonth) + 1;
                                fDate = "0" + dayOfMonth;
                                String paddedMonth = String.format("%02d", month);
                                editText.setText(fDate + "/" + paddedMonth + "/" + year);

                            } else {

                                fmonth = "0" + monthOfYear;
                                month = Integer.parseInt(fmonth) + 1;
                                String paddedMonth = String.format("%02d", month);
                                editText.setText(dayOfMonth + "/" + paddedMonth + "/" + year);
                            }


                        } catch (Exception e) {
                            e.printStackTrace();
                        }


                    }

                }, mYear, mMonth, mDay);
        datePickerDialog.getDatePicker().setMaxDate(System.currentTimeMillis());
        datePickerDialog.show();


    }


});

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。

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;
    }

}

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"
