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。

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")
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>
日期选择对话框
Calendar c=Calendar.getInstance();
Integer month=c.get(Calendar.MONTH);
Integer day=c.get(Calendar.DAY_OF_MONTH);
Integer year=c.get(Calendar.YEAR);
DatePickerDialog datePickerDialog =new DatePickerDialog(Expenture_Activity.this, new DatePickerDialog.OnDateSetListener() {
@Override
public void onDateSet(DatePicker view, int year, int month, int dayOfMonth) {
et_from.setText(dayOfMonth+"/"+month+"/"+year);
}
},year,month,day);
datePickerDialog.show();
Kotlin端口,调用setDatePicker函数
private fun setDatePicker(dateEditText: EditText) {
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)
updateLabel(myCalendar, dateEditText)
}
dateEditText.setOnClickListener {
DatePickerDialog(this@YourActivityName, datePickerOnDataSetListener, myCalendar
.get(Calendar.YEAR), myCalendar.get(Calendar.MONTH),
myCalendar.get(Calendar.DAY_OF_MONTH)).show()
}
}
private fun updateLabel(myCalendar: Calendar, dateEditText: EditText) {
val myFormat: String = "dd-MMM-yyyy"
val sdf = SimpleDateFormat(myFormat, Locale.UK)
dateEditText.setText(sdf.format(myCalendar.time))
}
如果你需要一个单一的功能,所有的活动,当调用将打开日期选择器,然后返回我选择的日期,然后为所有创建一个接口
public interface OnDatePickerLitionarCallBack {
void DatePicker(String selectedDate);
}
然后在活动中调用接口
public class MapsActivity extends FragmentActivity implements OnDatePickerLitionarCallBack {
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_maps);
findViewById(R.id.date_pick).setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View view) {
date_Picker(MapsActivity.this,MapsActivity.this);
}
});
}
@Override
public void DatePicker(String selectedDate) {
}
}
实现接口后,创建一个公共类用于访问任何活动或片段
public class Commons{
public static void date_Picker(Context context, OnDatePickerLitionarCallBack onDatePickerLitionarCallBack) {
final java.util.Calendar myCalendar = java.util.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(java.util.Calendar.YEAR, year);
myCalendar.set(java.util.Calendar.MONTH, monthOfYear);
myCalendar.set(java.util.Calendar.DAY_OF_MONTH, dayOfMonth);
String myFormat = "dd,MMM yyyy"; //In which you need put here
java.text.SimpleDateFormat sdf = new java.text.SimpleDateFormat(myFormat, Locale.US);
onDatePickerLitionarCallBack.DatePicker(sdf.format(myCalendar.getTime()));
}
};
DatePickerDialog datePickerDialog = new DatePickerDialog(context, date, myCalendar
.get(java.util.Calendar.YEAR), myCalendar.get(java.util.Calendar.MONTH),
myCalendar.get(java.util.Calendar.DAY_OF_MONTH));
datePickerDialog.show();
}
}
