Examples of basic usage of Android DatePicker and DatePickerDialog

This article describes the basic usage of Android DatePicker and DatePickerDialog. Share it for your reference, as follows:

DatePicker is used to set the time and alarm clock of your phone

1. Add a button control in the configuration file, and then add an event to the button to enable it to open DatePicker

//The following is anonymous internal class method(new (){
  @Override
  public void onClick(View v) {  //The callback function onCreateDialog() method can be called through the following method, where the parameters are passed to the onCreateDialog() method    //Be sure to use the onCreateDialog() method, because its return value is a Dialog object    showDialog(DATE_DIALOG_ID);
  }
});

2. After using the showDialog method, the callback function onCreateDialog() method will be called, and the time setter pops up in the form of a dialog box will be opened.

@Override
protected Dialog onCreateDialog(int id) {
  switch (id) {
  case DATE_DIALOG_ID:
    // mDateSetListener This parameter is used to tell Android to click the set callback function after setting the time    return new DatePickerDialog(this,
          mDateSetListener,
          2011, 10, 25);
  case TIME_DIALOG_ID:
    return new TimePickerDialog(this, mTimeSetListener, 14, 12, true);
  }
  return null;
}

3. According to the DatePickerDialog construction method, you need to add a "listener", that is, the method that the user will process after clicking the SET button.

// Some callback functions after DatePickerDialog is setpublic  mDateSetListener = new () {
  //The following parameters are the time after the user has set it  @Override
  public void onDateSet(DatePicker view, int year, int monthOfYear,
      int dayOfMonth) {
    ("");
    (new StringBuffer().append(year).append("-").append(monthOfYear).append("-").append(dayOfMonth));
  }
};

Expansion: Similarly, setting time is similar to this process
