我有自定義的事件與他們的日期列表視圖。如果該用途選擇列表上的特定項目，則我的程序將詢問用戶是否想要提醒該事件。我遇到了循環事件的問題。例如，對於位置1，如果我將提醒設置爲下午2:15和位置2，則會將提醒設置爲2:30。第二個列表的通知將會出現，而忽略第一個列表。我希望這兩個通知都能在各自的時間顯示。Android列表視圖循環
有人可以找出並幫助我如何循環列表，所以我可以設置列表上的任何項目的提醒。
請檢查OnClickResponse（）方法，這是我創建鬧鐘的地方。
'public class Product extends AppCompatActivity implements View.OnClickListener {
private List<list> myList = new ArrayList<list>();

在此行中輸入代碼在這裏」

我將第二個if語句的第二個參數更改爲1，但現在第一個正常工作，但第二個鬧鐘甚至沒有顯示 – timmy24565
您需要爲每個鬧鐘保持唯一。 –
請你解釋一下。謝謝。第一個出現，第二個出現，但沒有分開。當第二次報警被調用時，第一個報警仍然被覆蓋 – timmy24565
