我想显示日期选择器弹出窗口。我找到了一些例子，但我没有得到正确的。我有一个edittext，我希望当我点击edittext时，datepicker对话框应该弹出，设置日期后，日期应该显示在edittext在dd/mm/yyyy格式。请为我提供示例代码或良好的链接。

我对沙玛林的解决方案。基于Linh的MvvmCross的Android:
public class DatePickerEditText : EditText, DatePickerDialog.IOnDateSetListener
{
IDisposable _clickSubscription;
public override bool Clickable => true;
protected DatePickerEditText(IntPtr javaReference, JniHandleOwnership transfer)
: base(javaReference, transfer)
=> Init();
public DatePickerEditText(Context context) : base(context)
=> Init();
public DatePickerEditText(Context context, IAttributeSet attrs)
: base(context, attrs)
=> Init();
public DatePickerEditText(Context context, IAttributeSet attrs, int defStyleAttr)
: base(context, attrs, defStyleAttr)
=> Init();
public DatePickerEditText(Context context, IAttributeSet attrs, int defStyleAttr, int defStyleRes)
: base(context, attrs, defStyleAttr, defStyleRes)
=> Init();
protected override void Dispose(bool disposing)
{
if (disposing)
{
_clickSubscription?.Dispose();
_clickSubscription = null;
}
base.Dispose(disposing);
}
public void OnDateSet(DatePicker view, int year, int month, int dayOfMonth)
=> Text = view.DateTime.ToString("d", CultureInfo.CurrentUICulture);
void Init()
{
SetFocusable(ViewFocusability.NotFocusable);
_clickSubscription = this.WeakSubscribe(nameof(Click), OnClick);
}
void OnClick(object sender, EventArgs e)
{
var date = DateTime.Today;
try
{
date = DateTime.Parse(Text, CultureInfo.CurrentUICulture);
}
catch (Exception ex)
{
System.Diagnostics.Debug.WriteLine(ex);
}
var dialog = new DatePickerDialog(Context,
this,
date.Year,
date.Month,
date.Day);
dialog.Show();
}
}
来杯香草沙玛林。Android版本只需将WeakSubscribe替换为EditText的Click事件的常规订阅，不要忘记在Dispose方法覆盖中取消订阅。

<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();
}
}
}
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。
这在2020年1月对我有效
XML部分:
<EditText
android:id="@+id/etDOB"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:clickable="true"
android:editable="false"
android:ems="10"
android:hint="Enter Your Date of Birth" />
Java的部分:
final Calendar myCalendar = Calendar.getInstance();
userDOBView = (EditText)findViewById(R.id.etDOB);
final DatePickerDialog.OnDateSetListener date = new DatePickerDialog.OnDateSetListener(){
@Override
public void onDateSet(DatePicker view, int year, int monthOfYear, int dayOfMonth) {
myCalendar.set(Calendar.YEAR, year);
myCalendar.set(Calendar.MONTH, monthOfYear);
myCalendar.set(Calendar.DAY_OF_MONTH, dayOfMonth);
updateLabel();
}
};
userDOBView.setOnTouchListener(new View.OnTouchListener(){
@Override
public boolean onTouch(View v, MotionEvent event){
if(event.getAction() == MotionEvent.ACTION_DOWN){
new DatePickerDialog("YourClassName".this, date,
myCalendar.get(Calendar.YEAR),
myCalendar.get(Calendar.MONTH),
myCalendar.get(Calendar.DAY_OF_MONTH)).show();
}
return true;
}
});
private void updateLabel() {
String myFormat = "MM/dd/yyyy"; //In which you need put here
SimpleDateFormat sdf = new SimpleDateFormat(myFormat, Locale.US);
// edittext.setText(sdf.format(myCalendar.getTime()));
userDOBView.setText(sdf.format(myCalendar.getTime()));
}
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();
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();
}
});
