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。
当前回答
我已经尝试了所有建议的方法,但它们都有各自的问题。
在我看来,最好的解决方案是使用如下的框架布局:
<FrameLayout
android:layout_width="match_parent"
android:layout_height="wrap_content" >
<EditText
android:layout_width="match_parent"
android:layout_height="wrap_content"
.... />
<View
android:id="@+id/invisible_click_watcher"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:clickable="true" />
</FrameLayout>
然后添加DatePickerDialog代码,这个代码在@Android的回答中写得很漂亮。
其他回答
# 1。我想显示一个datepicker与当前日期预选(我使用butterknife注入)
@OnClick(R.id.your_view) public void onClickYourView() {
final 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);
String myFormat = "dd MMMM yyyy"; // your format
SimpleDateFormat sdf = new SimpleDateFormat(myFormat, Locale.getDefault());
your_view.setText(sdf.format(myCalendar.getTime()));
}
};
new DatePickerDialog(mContext, date, myCalendar.get(Calendar.YEAR), myCalendar.get(Calendar.MONTH), myCalendar.get(Calendar.DAY_OF_MONTH)).show();
}
2. 如果您想预选日期,请将最后一部分替换为
new DatePickerDialog(mContext, date, 1990, 0, 1).show();
然后你可以使用myCalendar变量或直接在视图上的文本来获取它。
用这个简单的技巧来做吧:
步骤1:创建一个片段对话框
public class DatePickerFragmentDialog extends DialogFragment {
@Override
public Dialog onCreateDialog(Bundle savedInstanceState) {
Calendar c = Calendar.getInstance();
int year = c.get(Calendar.YEAR);
int month = c.get(Calendar.MONTH);
int day = c.get(Calendar.DAY_OF_MONTH);
return new DatePickerDialog(getActivity(), (DatePickerDialog.OnDateSetListener) getActivity(), year, month, day);
}
}
第二步:在必要的活动中遵循这一点
该活动必须实现:DatePickerDialog。OnDateSetListener 在按钮上设置onClickListener: DialogFragment datePicker = new DatePickerFragmentDialog(); datePicker.show(getSupportFragmentManager(), "自定义日期选择器");
步骤3:覆盖OnDateSetListener
public void onDateSet(DatePicker view, int year, int month, int dayOfMonth) {
Calendar calendar = Calendar.getInstance();
calendar.set(Calendar.YEAR, year);
calendar.set(Calendar.MONTH, month);
calendar.set(Calendar.DAY_OF_MONTH, dayOfMonth);
@SuppressLint("SimpleDateFormat") DateFormat dateFormat = new
SimpleDateFormat("MM/dd/yyyy");
String currentDateString = dateFormat.format(calendar.getTime());
tvPaymentDate.setText(currentDateString);
}
因此,我们可以使用任何格式的日期:)
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。
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;
}
}
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();
}
}
