java - Android 日历 Intent 完成后执行操作

Question

我正在调用以下函数来添加日历事件(主要取自 roman10 ):

private void addEvent() {
    Intent l_intent = new Intent(Intent.ACTION_EDIT);
    l_intent.setType("vnd.android.cursor.item/event");
    l_intent.putExtra("title", "roman10 calendar tutorial test");
    l_intent.putExtra("description", "This is a simple test for calendar api");
    l_intent.putExtra("eventLocation", "@home");
    l_intent.putExtra("beginTime", System.currentTimeMillis());
    l_intent.putExtra("endTime", System.currentTimeMillis() + 1800*1000);
    l_intent.putExtra("allDay", 0);
    l_intent.putExtra("eventStatus", 1);
    l_intent.putExtra("visibility", 0);
    l_intent.putExtra("transparency", 0);
    l_intent.putExtra("hasAlarm", 1);

    try {
        startActivity(l_intent);
    } catch (Exception e) {
        Toast.makeText(this.getApplicationContext(), "Sorry, no compatible calendar is found!", Toast.LENGTH_LONG).show();
    }
}

完成此 Intent 后，我想手动刷新我的列表 Activity ，该 Activity 仅保存所有用户事件的列表(我希望它立即反射(reflect)更改)。有谁知道有什么方法可以做到这一点？是否有任何特定的函数在完成此 Intent 时被调用，我可以修改？

最好的选择是使用 startActivityForResults(Intent, id)

static private final int CALENDAR_DONE 101;
startActivityForResults(l_intent, CALENDAR_DONE);

然后将此函数添加到您的 Activity 中:

public void onActivityResult(int reqCode, int resultCode, Intent data) {
    super.onActivityResult(reqCode, resultCode, data);

    switch (reqCode) {
      case (CALENDAR_DONE) :
        if (resultCode == Activity.RESULT_OK) {
          //Do stuff here
        }       
      break;
    }
  }
