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);
} 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")
还有另一种更好的可重用方式:
创建一个类:
class setDate implements OnFocusChangeListener, OnDateSetListener {
private EditText editText;
private Calendar myCalendar;
public setDate(EditText editText, Context ctx){
this.editText = editText;
this.editText.setOnFocusChangeListener(this);
myCalendar = Calendar.getInstance();
}
@Override
public void onDateSet(DatePicker view, int year, int monthOfYear, int dayOfMonth) {
// this.editText.setText();
String myFormat = "MMM dd, yyyy"; //In which you need put here
SimpleDateFormat sdformat = new SimpleDateFormat(myFormat, Locale.US);
myCalendar.set(Calendar.YEAR, year);
myCalendar.set(Calendar.MONTH, monthOfYear);
myCalendar.set(Calendar.DAY_OF_MONTH, dayOfMonth);
editText.setText(sdformat.format(myCalendar.getTime()));
}
@Override
public void onFocusChange(View v, boolean hasFocus) {
// TODO Auto-generated method stub
if(hasFocus){
new DatePickerDialog(ctx, this, myCalendar
.get(Calendar.YEAR), myCalendar.get(Calendar.MONTH),
myCalendar.get(Calendar.DAY_OF_MONTH)).show();
}
}
}
然后在onCreate函数下调用这个类:
EditText editTextFromDate = (EditText) findViewById(R.id.editTextFromDate);
setDate fromDate = new setDate(editTextFromDate, this);
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();
}
}
试试这个
btn=(Button)findViewById(R.id.chs);
final Dialog dialog = new Dialog(MainActivity.this);
dialog.setCanceledOnTouchOutside(true);
btn.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
dialog.setContentView(R.layout.datepickerdialog);
dp=(DatePicker) dialog.findViewById(R.id.btp);
dialog.show();
ok=(Button)dialog.findViewById(R.id.btn1);
ok.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
dialog.dismiss();
}
});
}
});
我不能得到这些工作中的任何人，所以将添加我的一个，以防它有帮助。
public class MyEditTextDatePicker implements OnClickListener, OnDateSetListener {
EditText _editText;
private int _day;
private int _month;
private int _birthYear;
private Context _context;
public MyEditTextDatePicker(Context context, int editTextViewID)
{
Activity act = (Activity)context;
this._editText = (EditText)act.findViewById(editTextViewID);
this._editText.setOnClickListener(this);
this._context = context;
}
@Override
public void onDateSet(DatePicker view, int year, int monthOfYear, int dayOfMonth) {
_birthYear = year;
_month = monthOfYear;
_day = dayOfMonth;
updateDisplay();
}
@Override
public void onClick(View v) {
Calendar calendar = Calendar.getInstance(TimeZone.getDefault());
DatePickerDialog dialog = new DatePickerDialog(_context, this,
calendar.get(Calendar.YEAR), calendar.get(Calendar.MONTH),
calendar.get(Calendar.DAY_OF_MONTH));
dialog.show();
}
// updates the date in the birth date EditText
private void updateDisplay() {
_editText.setText(new StringBuilder()
// Month is 0 based so add 1
.append(_day).append("/").append(_month + 1).append("/").append(_birthYear).append(" "));
}
}
还有其他书里没有提到的东西。确保将以下内容放在EditText xml上。
android:focusable="false"
否则，就像在我的例子中，键盘会不断弹出。
