android - 如何阅读添加到日历的事件/条目？

Question

我现在可以添加条目了。在我的应用程序中，用户可以在他的日历上输入约会/事件。但在他这样做之前，它应该向他显示他已经添加的事件。它应该从日历中获取事件并将其显示给他。这该怎么做？我被困在这部分。提前致谢。

Answer 1

Cursor cursor = cr.query(Uri.parse("content://com.android.calendar/events"), new String[]{ "calendar_id", "title", "description", "dtstart", "dtend", "eventLocation" }, null, null, null);         
    //Cursor cursor = cr.query(Uri.parse("content://calendar/calendars"), new String[]{ "_id", "name" }, null, null, null);
    String add = null;
    cursor.moveToFirst();
    String[] CalNames = new String[cursor.getCount()];
    int[] CalIds = new int[cursor.getCount()];
    for (int i = 0; i < CalNames.length; i++) {
        CalIds[i] = cursor.getInt(0);
        CalNames[i] = "Event"+cursor.getInt(0)+": \nTitle: "+ cursor.getString(1)+"\nDescription: "+cursor.getString(2)+"\nStart Date: "+new Date(cursor.getLong(3))+"\nEnd Date : "+new Date(cursor.getLong(4))+"\nLocation : "+cursor.getString(5);
        if(add == null)
            add = CalNames[i];
        else{
            add += CalNames[i];
        }           
        ((TextView)findViewById(R.id.calendars)).setText(add);

        cursor.moveToNext();
    }
    cursor.close();

这将读取日历条目。
