java - 自动关闭 DatePickerDialog

Question

我正在使用以下代码从 EditText 创建一个 DatePickerDialog。

import android.widget.DatePicker;
import android.app.DatePickerDialog;
import java.text.SimpleDateFormat;
import java.util.Calendar;
import java.util.Locale;

Calendar myCalendar = Calendar.getInstance();

String myFormat = "MM/dd/yy";
SimpleDateFormat sdf = new SimpleDateFormat(myFormat, Locale.US);

@Override
    protected void onCreate(Bundle savedInstanceState) {

EditText datePicker = (EditText) findViewById(R.id.popUpDate);
datePicker.setText(sdf.format(myCalendar.getTime()));

datePicker.setOnClickListener(new View.OnClickListener() {

    @Override
    public void onClick(View v) {
        new DatePickerDialog(AddAccount.this, R.style.AppTheme_Dialog, 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);
                datePicker.setText(sdf.format(myCalendar.getTime()));
            }
        }, myCalendar.get(Calendar.YEAR), myCalendar.get(Calendar.MONTH),
                myCalendar.get(Calendar.DAY_OF_MONTH)).show();
    }
});
}

是否可以在选择日期后让默认的自动关闭？还是需要完全重制 datepicker 小部件？

Answer 1

DatePickerDialog包含 DatePicker .和 DatePicker有OnDateChangedListener .
您可以使用 OnDateChangedListener当你选择一个日期时对听众说

final Calendar calendar = Calendar.getInstance();
int year = calendar.get(Calendar.YEAR);
int month = calendar.get(Calendar.MONTH);
int day = calendar.get(Calendar.DAY_OF_MONTH);

final DatePickerDialog datePickerDialog =
    new DatePickerDialog(YourActivity.this, null, year, month, day);

datePickerDialog.getDatePicker()
    .init(year, month, day, new DatePicker.OnDateChangedListener() {
        @Override
        public void onDateChanged(DatePicker view, int year, int monthOfYear,
            int dayOfMonth) {
            Toast.makeText(YourActivity.this, "day" + dayOfMonth + "-month" + monthOfYear + 1 + "-year" + year, Toast.LENGTH_SHORT).show();
            // dismiss the popup when choose a date 
            datePickerDialog.dismiss();
        }
    });
datePickerDialog.show();

此解决方案适用于您的情况，但我认为它在用户体验 (UX) 方面不是很好，因为几乎 Android 应用程序使用默认的 DatePickerDialog 流程
