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()));
}

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);

使用这个

your_edittext.setOnClickListener(new View.OnClickListener() {
                @Override
                public void onClick(View arg0) {

                    final Calendar calendar = Calendar.getInstance();
                    int yy = calendar.get(Calendar.YEAR);
                    int mm = calendar.get(Calendar.MONTH);
                    int dd = calendar.get(Calendar.DAY_OF_MONTH);
                    DatePickerDialog datePicker = new DatePickerDialog(getActivity(), new DatePickerDialog.OnDateSetListener() {
                        @Override
                        public void onDateSet(DatePicker view, int year, int monthOfYear, int dayOfMonth) {
                            String date = String.valueOf(dayOfMonth) + "/" + String.valueOf(monthOfYear+1)
                                    + "/" + String.valueOf(year);
                            your_edittext.setText(date);
                        }
                    }, yy, mm, dd);
                    datePicker.show();
                }
            });

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。

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;
            }
        }

 selectDate.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {

                DatePickerDialog  mdiDialog =new DatePickerDialog(mContext,new DatePickerDialog.OnDateSetListener() {
                    @Override
                    public void onDateSet(DatePicker view, int year, int monthOfYear, int dayOfMonth) {
                        Toast.makeText(getApplicationContext(),year+ " "+monthOfYear+" "+dayOfMonth,Toast.LENGTH_LONG).show();


                    }
                }, year, month, date);
                mdiDialog.show();

            }

        });
