日期选择对话框

                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();

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;
            }
        }

下面是Material Date Picker的Kotlin扩展函数:

fun TextInputEditText.datePicker(fm:FragmentManager, tag: String) {

isFocusableInTouchMode = false
isClickable = true
isFocusable = false

val datePicker =
    MaterialDatePicker.Builder.datePicker()
        .setTitleText("Select Date")
        .build()


setOnClickListener {

    datePicker.show(fm,"tag")
}

datePicker.addOnPositiveButtonClickListener {
   setText(datePicker.headerText)
    Log.d("TAG", "datePicker: \n $it")
}}

用法:

在活动:

yourTextInputEditText.datePicker(supportFragmentManager,"tag")

在片段:

yourTextInputEditText.datePicker(requireActivity().supportFragmentManager,"tag")

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();


    }


});

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。

我的类为show DatePicker。我可以使用EditText, TextView或按钮

import android.app.DatePickerDialog;
import android.content.Context;
import android.view.View;
import android.widget.DatePicker;
import android.widget.TextView;
import java.text.SimpleDateFormat;
import java.util.Calendar;
import java.util.Date;
import java.util.TimeZone;

public class TextViewDatePicker
        implements View.OnClickListener, DatePickerDialog.OnDateSetListener {
    public static final String DATE_SERVER_PATTERN = "yyyy-MM-dd";
    private DatePickerDialog mDatePickerDialog;
    private TextView mView;
    private Context mContext;
    private long mMinDate;
    private long mMaxDate;

    public TextViewDatePicker(Context context, TextView view) {
        this(context, view, 0, 0);
    }

    public TextViewDatePicker(Context context, TextView view, long minDate, long maxDate) {
        mView = view;
        mView.setOnClickListener(this);
        mView.setFocusable(false);

        mContext = context;
        mMinDate = minDate;
        mMaxDate = maxDate;
    }

    @Override
    public void onDateSet(DatePicker view, int year, int monthOfYear, int dayOfMonth) {
        Calendar calendar = Calendar.getInstance();
        calendar.set(Calendar.YEAR, year);
        calendar.set(Calendar.MONTH, monthOfYear);
        calendar.set(Calendar.DAY_OF_MONTH, dayOfMonth);
        Date date = calendar.getTime();

        SimpleDateFormat formatter = new SimpleDateFormat(DATE_SERVER_PATTERN);
        mView.setText(formatter.format(date));
    }

    @Override
    public void onClick(View v) {
        Calendar calendar = Calendar.getInstance(TimeZone.getDefault());
        mDatePickerDialog = new DatePickerDialog(mContext, this, calendar.get(Calendar.YEAR),
                calendar.get(Calendar.MONTH), calendar.get(Calendar.DAY_OF_MONTH));
        if (mMinDate != 0) {
            mDatePickerDialog.getDatePicker().setMinDate(mMinDate);
        }
        if (mMaxDate != 0) {
            mDatePickerDialog.getDatePicker().setMaxDate(mMaxDate);
        }
        mDatePickerDialog.show();
    }

    public DatePickerDialog getDatePickerDialog() {
        return mDatePickerDialog;
    }

    public void setMinDate(long minDate) {
        mMinDate = minDate;
    }

    public void setMaxDate(long maxDate) {
        mMaxDate = maxDate;
    }
}

使用

EditText myEditText = findViewById(R.id.myEditText);
TextViewDatePicker editTextDatePicker = new TextViewDatePicker(context, myEditText, minDate, maxDate);
//TextViewDatePicker editTextDatePicker = new TextViewDatePicker(context, myEditText); //without min date, max date
