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。

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;
}
}

<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"

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,

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();
}
}
}
我认为最好重写EditText类…
public class EditTextDP extends android.support.v7.widget.AppCompatEditText implements View.OnClickListener, DatePickerDialog.OnDateSetListener {
public EditTextDP(Context context) {
super(context);
setOnClickListener(this);
setFocusable(false);
}
public EditTextDP(Context context, AttributeSet attrs) {
super(context, attrs);
setOnClickListener(this);
setFocusable(false);
}
public EditTextDP(Context context, AttributeSet attrs, int defStyleAttr) {
super(context, attrs, defStyleAttr);
setOnClickListener(this);
setFocusable(false);
}
@Override
public void onDateSet(DatePicker view, int year, int monthOfYear, int dayOfMonth) {
setText(new StringBuilder().append(dayOfMonth).append("/").append(monthOfYear + 1).append("/").append(year));
}
@Override
public void onClick(View v) {
Calendar calendar = Calendar.getInstance(TimeZone.getDefault());
DatePickerDialog dialog = new DatePickerDialog(getContext(), this, calendar.get(Calendar.YEAR), calendar.get(Calendar.MONTH), calendar.get(Calendar.DAY_OF_MONTH));
dialog.show();
}
}
然后在XML中使用它…
<*.*.*.EditTextDP
android:id="@+id/c1_dob_hm"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:background="@drawable/round_edittext_white"
android:ems="10"
android:padding="8dp">
</*.*.*.EditTextDP>
class MyClass implements OnClickListener, OnDateSetListener {
EditText editText;
this.editText = (EditText) findViewById(R.id.editText);
this.editText.setOnClickListener(this);
@Override
public void onClick(View v) {
DatePickerDialog dialog = new DatePickerDialog(this, this, 2013, 2, 18);
dialog.show();
}
@Override
public void onDateSet(DatePicker view, int year, int monthOfYear, int dayOfMonth) {
// this.editText.setText();
}
}
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。
