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。

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);

editText.setText(dayOfMonth + "/" + paddedMonth + "/" + year);

}, mYear, mMonth, mDay);
datePickerDialog.getDatePicker().setMaxDate(System.currentTimeMillis());
datePickerDialog.show();

其他回答
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;
}
}
}
试试这个:
public class DatePickerFragment extends DialogFragment implements DatePickerDialog.OnDateSetListener {
DataPickerListener listener;
public DatePickerFragment(DataPickerListener l) {
listener = l;
}
@Override
public Dialog onCreateDialog(Bundle savedInstanceState) {
// Use the current date as the default date in the date 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);
return new DatePickerDialog(getActivity(),
AlertDialog.THEME_HOLO_LIGHT, this, year, month, day);
}
public void onDateSet(DatePicker view, int year, int month, int day) {
month = month + 1;
String stringOfDate = day + "-" + month + "-" + year;
listener.setDate(stringOfDate);
Util.Log(stringOfDate);
}
@Override
public void onCancel(DialogInterface dialog) {
// TODO Auto-generated method stub
super.onCancel(dialog);
listener.cancel();
}
public static interface DataPickerListener {
void setDate(String date);
void cancel();
}
}
// use this function to open datePicker popup
DialogFragment newFragment;
public void pickDate() {
if (newFragment == null)
newFragment = new DatePickerFragment(new PickDateListener());
newFragment.show(getFragmentManager(), "Date Picker");
}
class PickDateListener implements DataPickerListener {
@Override
public void setDate(String date) {
createSpiner(date);
onetouch = false;
}
@Override
public void cancel() {
onetouch = false;
}
}
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")
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;
}

var view = inflater.Inflate(Resource.Layout.EnterTimeView, container, false);

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;
}
