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。

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()));
}

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;
}
}
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()
}
}
把这4行放在(EditText, AppCompatEditText)上。它不会显示键盘。然后在clicklistener上,你可以显示datePicker
android:clickable="false"
android:cursorVisible="false"
android:focusable="false"
android:focusableInTouchMode="false"
这是我怎么做的:类似于选择的答案,但使用一个静态对话框类,所以它更可重用,也使用onFocusChange而不是onClick。
editText.setOnFocusChangeListener(new View.OnFocusChangeListener() {
@Override
public void onFocusChange(View v, boolean hasFocus) {
if (hasFocus) {
DialogFragment datePickerFragment = new DatePickerFragment() {
@Override
public void onDateSet(DatePicker view, int year, int month, int day) {
Log.d(TAG, "onDateSet");
Calendar c = Calendar.getInstance();
c.set(year, month, day);
editText.setText(df.format(c.getTime()));
nextField.requestFocus(); //moves the focus to something else after dialog is closed
}
};
datePickerFragment.show(getActivity().getSupportFragmentManager(), "datePicker");
}
}
});
datepicker对话框。
public static class DatePickerFragment extends DialogFragment implements DatePickerDialog.OnDateSetListener{
@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);
// Create a new instance of DatePickerDialog and return it
return new DatePickerDialog(getActivity(), this, year, month, day);
}
@Override
public void onDateSet(DatePicker view, int year, int month, int day) {
//blah
}
}
import android.app.DatePickerDialog;
import android.content.Context;
import android.view.View;
import android.widget.DatePicker;
import android.widget.TextView;

public class DatePickerHelper {

private TextView textView = null;
public DatePickerHelper(final Context context, TextView textView) {
this.textView = textView;
// Setup on click listener if the TextView is not null
if (textView != null) {
textView.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
getDatePickerDialog(context).show();
}
});
}
}
/**

private DatePickerDialog.OnDateSetListener getOnDateSetListener() {

textView.setText(sdf.format(calendar.getTime()));

/**

用法:
DatePickerHelper assessmentDueDateHelper = new DatePickerHelper(AssessmentsDetailActivity.this,
(TextView) findViewById(R.id.assessmentDueDateEditText));
