在XML中添加TextView和Button
<TextView
android:id="@+id/searchText"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="TextView" />
<Button
android:id="@+id/search"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Search" />
在java文件中添加以下代码
public class DatePickerDialogExample extends Activity {
TextView txtDate;
private int mYear, mMonth, mDay, mHour, mMinute;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
txtDate = (TextView) findViewById(R.id.searchText);
Button search = (Button) findViewById(R.id.search);
search.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
// Process to get Current Date
final Calendar c = Calendar.getInstance();
mYear = c.get(Calendar.YEAR);
mMonth = c.get(Calendar.MONTH);
mDay = c.get(Calendar.DAY_OF_MONTH);
// Launch Date Picker Dialog
DatePickerDialog dpd = new DatePickerDialog(PrayTimeActivity.this,
new DatePickerDialog.OnDateSetListener() {
@Override
public void onDateSet(DatePicker view, int year,
int monthOfYear, int dayOfMonth) {
// Display Selected date in textbox
txtDate.setText(dayOfMonth + "-"
+ (monthOfYear + 1) + "-" + year);
}
}, mYear, mMonth, mDay);
dpd.show();
}
});
}
}

请你试试这个：DatePickerDialog
答案 2 :(得分：0)
PS：在setOnClickListener解决问题之前启动日，月和年变量。
OR
试试这个简单的套餐：
public class DialogSelectDate extends AppCompatActivity {
/**
* Desenvolvido por Eduardo Ferreira
* Simple DialogBox to DatePicker
* @param _context
* @param fromDateEtxt
* @param dateFormatter
*/
static void DialogDate(Context _context , final EditText fromDateEtxt , final SimpleDateFormat dateFormatter) {
fromDateEtxt.setInputType(InputType.TYPE_NULL);
fromDateEtxt.requestFocus();
Calendar newCalendar = Calendar.getInstance();
final DatePickerDialog fromDatePickerDialog = new DatePickerDialog(_context, new DatePickerDialog.OnDateSetListener() {
public void onDateSet(DatePicker view , int year , int monthOfYear , int dayOfMonth) {
Calendar newDate = Calendar.getInstance();
newDate.set(year , monthOfYear , dayOfMonth);
fromDateEtxt.setText(dateFormatter.format(newDate.getTime()));
}
} , newCalendar.get(Calendar.YEAR) , newCalendar.get(Calendar.MONTH) , newCalendar.get(Calendar.DAY_OF_MONTH));
fromDateEtxt.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
fromDatePickerDialog.show();
}
});
}
}
调用你的项目
EditText ed_edittext = findViewById(R.id.edittext);
SimpleDateFormat dateFormatter = new SimpleDateFormat(`dd-MM-yyyy`, locale.US);
DialogSelectDate.DialogDate(this, ed_edittext, dateFormatter );

Date Picker Dialog in Android Kotlin: - In This Dialog you can set min and max Date: -
val dp = fromDatePickerDialog.datePicker dp.minDate = System.currentTimeMillis()
fun getDateDialog(textView: TextView, sActivity: Activity?): DatePickerDialog? {
val fromDatePickerDialog: DatePickerDialog
val newCalendar: Calendar = Calendar.getInstance()
val dateFormatter = SimpleDateFormat("MMM/dd/yyyy", Locale.US)
fromDatePickerDialog = DatePickerDialog(
sActivity!!,
{ view, year, monthOfYear, dayOfMonth ->
val newDate: Calendar = Calendar.getInstance()
newDate.set(year, monthOfYear, dayOfMonth)
textView.setText(dateFormatter.format(newDate.getTime()))
},
newCalendar.get(Calendar.YEAR),
newCalendar.get(Calendar.MONTH),
newCalendar.get(Calendar.DAY_OF_MONTH)
)
val dp = fromDatePickerDialog.datePicker
dp.minDate = System.currentTimeMillis()
fromDatePickerDialog.show()
return fromDatePickerDialog
}

试试这个，你可以设置最大日期最小日期并格式化日期
fun showDatePicker(context: Context, maximumDate: Long? = null, minimumDate: Long? = null, dateFormat: String = "dd/MM/yyyy",callBack: (String) -> Unit) {
val c = Calendar.getInstance()
val year = c.get(Calendar.YEAR)
val month = c.get(Calendar.MONTH)
val day = c.get(Calendar.DAY_OF_MONTH)
val dateSetListener = DatePickerDialog.OnDateSetListener { _, _year, monthOfYear, dayOfMonth ->
c.set(Calendar.YEAR, _year)
c.set(Calendar.MONTH, monthOfYear)
c.set(Calendar.DAY_OF_MONTH, dayOfMonth)
val sdf = SimpleDateFormat(dateFormat, Locale.US)
callBack(sdf.format(c.time))
}
val datePickerDialog = DatePickerDialog(context, dateSetListener, year, month, day)
if (minimumDate != null) {
datePickerDialog.datePicker.minDate = minimumDate
}
if (maximumDate != null) {
datePickerDialog.datePicker.maxDate = maximumDate
}
datePickerDialog.show()
}

演示如何使用DatePickerDialog的简单示例：
Calendar c = Calendar.getInstance();
new DatePickerDialog(this, new OnDateSetListener() {
@Override
public void onDateSet(DatePicker view, int year, int monthOfYear, int dayOfMonth) {
// Do something here
}
}, c.get(Calendar.YEAR), c.get(Calendar.MONTH), c.get(Calendar.DAY_OF_MONTH)).show();
