做下载功能, Notification打开下载列表, 产品要求此时点击返回按钮, 恢复到之前的
HomeActivity, 会者不难, PengingIntent中增加getActivities即可
注意设置HomeActivity为singleTask, 防止重复打开两个HomeActivity的问题
已知问题: 在下载列表页面下, 点击通知栏打开DownloadListActivity, 会导致DownloadListActivity重启
val intentHome = Intent(this, HomeActivity::class.java) intentHome.flags = Intent.FLAG_ACTIVITY_NEW_TASK val intent = Intent(this, DownloadListActivity::class.java) val pi = PendingIntent.getActivities(this, 0, arrayOf(intentHome, intent), PendingIntent.FLAG_CANCEL_CURRENT)
