如何在kotlin中获取日历事件？

import android.content.ContentResolver
import android.content.ContentUris
import android.content.Context
import android.database.Cursor
import android.net.Uri
import android.provider.CalendarContract

fun getCalendarEvents(context: Context): List<String> {
    val events: MutableList<String> = mutableListOf()

    // 查询日历事件的URI
    val uri: Uri = CalendarContract.Events.CONTENT_URI

    // 定义要查询的字段
    val projection: Array<String> = arrayOf(
        CalendarContract.Events.TITLE,
        CalendarContract.Events.DESCRIPTION,
        CalendarContract.Events.DTSTART,
        CalendarContract.Events.DTEND
    )

    // 获取ContentResolver
    val contentResolver: ContentResolver = context.contentResolver

    // 查询日历事件
    val cursor: Cursor? = contentResolver.query(uri, projection, null, null, null)

    cursor?.use {
        // 遍历查询结果
        while (it.moveToNext()) {
            val title: String = it.getString(it.getColumnIndex(CalendarContract.Events.TITLE))
            val description: String = it.getString(it.getColumnIndex(CalendarContract.Events.DESCRIPTION))
            val startTime: Long = it.getLong(it.getColumnIndex(CalendarContract.Events.DTSTART))
            val endTime: Long = it.getLong(it.getColumnIndex(CalendarContract.Events.DTEND))

            // 将事件信息添加到列表中
            events.add("Title: $title\nDescription: $description\nStart Time: $startTime\nEnd Time: $endTime\n")
        }
    }

    return events
}
