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。

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()));
}

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();
}
});
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@DrunkenDaddy扩展函数，至少在我的情况下(以编程方式创建EditText)，它在第一次单击时显示键盘，然后在第二次单击时显示日期选择器。
显然，将isFocusable和isFocusableInTouchMode设置为false是无关紧要的，因为第一次点击总是被EditText解释为焦点变化。因此，当EditText获得焦点时，我必须触发单击。现在它像预期的那样工作:第一次点击它直接打开日期选择器，而不是键盘(感谢设置showSoftInputOnFocus为false):
fun EditText.transformIntoDatePicker(context: Context, format: String = "dd/MM/yyyy", maxDate: Date? = null) {
isClickable = true
showSoftInputOnFocus = false
isCursorVisible = false
setOnFocusChangeListener { _, hasFocus -> if (hasFocus) callOnClick()}
val myCalendar = Calendar.getInstance()
val datePickerOnDataSetListener =
DatePickerDialog.OnDateSetListener { _, year, monthOfYear, dayOfMonth ->
myCalendar.set(Calendar.YEAR, year)
myCalendar.set(Calendar.MONTH, monthOfYear)
myCalendar.set(Calendar.DAY_OF_MONTH, dayOfMonth)
val sdf = SimpleDateFormat(format, Locale.getDefault())
setText(sdf.format(myCalendar.time))
}
setOnClickListener {
DatePickerDialog(
context, datePickerOnDataSetListener,
myCalendar.get(Calendar.YEAR), myCalendar.get(Calendar.MONTH),
myCalendar.get(Calendar.DAY_OF_MONTH)
).run {
maxDate?.time?.also { datePicker.maxDate = it }
show()
}
}
