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。

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())

public class DatePickerActivity extends AppCompatActivity {
    Button button;
    static TextView textView;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        button= (Button) findViewById(R.id.btn_click);
        textView= (TextView) findViewById(R.id.txt_date);



        button.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                DialogFragment newFragment=new DatePickerFragment();
                newFragment.show(getFragmentManager(), "datepicker");
            }
        });

    }

    public class DatePickerFragment extends DialogFragment implements    DatePickerDialog.OnDateSetListener{
        @Override
        public void onDateSet(DatePicker view, int year, int monthOfYear, int  day) {
            String years=""+year;
            String months=""+(monthOfYear+1);
            String days=""+day;
            if(monthOfYear>=0 && monthOfYear<9){
                months="0"+(monthOfYear+1);
            }
            if(day>0 && day<10){
                days="0"+day;

            }
            textView.setText(days+"/"+months+"/"+years);


        }

        @Override
        public Dialog onCreateDialog(Bundle savedInstanceState) {
            //use the current date as the default date in the 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);
            DatePickerDialog datePickerDialog=null;
            datePickerDialog=new DatePickerDialog(getActivity(), this, year,  month, day);

            return datePickerDialog;
        }

    }

}

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
    android:id="@+id/date"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:ems="10"
    android:hint="DD/MM/YYYY"
    android:inputType="date"
    android:focusable="false"/>

<EditText
    android:id="@+id/time"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:hint="00:00"
    android:inputType="time"
    android:focusable="false"/>

JAVA文件

import android.app.DatePickerDialog;
import android.app.TimePickerDialog;
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.view.View;
import android.widget.DatePicker;
import android.widget.EditText;
import android.widget.TimePicker;

import java.util.Calendar;

public class MainActivity extends AppCompatActivity implements View.OnClickListener {

    EditText selectDate,selectTime;
    private int mYear, mMonth, mDay, mHour, mMinute;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        selectDate=(EditText)findViewById(R.id.date);
        selectTime=(EditText)findViewById(R.id.time);

        selectDate.setOnClickListener(this);
        selectTime.setOnClickListener(this);




    }

    @Override
    public void onClick(View view) {

        if (view == selectDate) {
            final Calendar c = Calendar.getInstance();
            mYear = c.get(Calendar.YEAR);
            mMonth = c.get(Calendar.MONTH);
            mDay = c.get(Calendar.DAY_OF_MONTH);


            DatePickerDialog datePickerDialog = new DatePickerDialog(this,
                    new DatePickerDialog.OnDateSetListener() {

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

                            selectDate.setText(dayOfMonth + "-" + (monthOfYear + 1) + "-" + year);

                        }
                    }, mYear, mMonth, mDay);
            datePickerDialog.show();
        }
        if (view == selectTime) {

            // Get Current Time
            final Calendar c = Calendar.getInstance();
            mHour = c.get(Calendar.HOUR_OF_DAY);
            mMinute = c.get(Calendar.MINUTE);

            // Launch Time Picker Dialog
            TimePickerDialog timePickerDialog = new TimePickerDialog(this,
                    new TimePickerDialog.OnTimeSetListener() {

                        @Override
                        public void onTimeSet(TimePicker view, int hourOfDay,
                                              int minute) {

                            selectTime.setText(hourOfDay + ":" + minute);
                        }
                    }, mHour, mMinute, false);
            timePickerDialog.show();
        }
    }
}

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;
            }
        }
