取消android等待意圖

我遇到過多個解決方案，關於如何取消掛起的意圖，但無濟於事。我也一直無法觸發取消，其中我已經在一個點擊功能的代碼。觸發該功能的按鈕是代碼生成的。取消無法被解僱並繼續到指定的接收者，這裏是我的代碼：取消android等待意圖

方面看都在點擊中設定的報警方法，在通斷按鈕取消代碼

那麼，你必須在那裏現在肯定是行不通的代碼：

PendingIntent.getBroadcast(getBaseContext(),count, getIntent(), 0).cancel();

使用getIntent()這裏是使用您的Activity開始與Intent。

如果您在使用本PendingIntent設置報警：

Intent i = new Intent(getBaseContext(), AlarmReceiver.class); 
PendingIntent pendingIntent = 
    PendingIntent.getBroadcast(getBaseContext(), count, i, 0); 

manager.cancel(pendingIntent); 
pendingIntent.cancel();

如果這不是爲你工作，那麼很可能值：

PendingIntent pendingIntent = 
    PendingIntent.getBroadcast(getBaseContext(),count, intent, 0);

您使用本應取消count是不一樣的。這兩個調用中的值count必須相同。

啊我看到生病給它一個嘗試（：謝謝!!! –

哦，我試着做這個，但對於經理，如果我在onclick裏面創建一個局部變量Alarmmanager管理器，它是指同一個我用於設置？ –

只有一個'AlarmManager'，你可以在一個字段（成員變量）中存儲對'AlarmManager'的引用，或者你可以調用'getSystemService（Context.ALARM_SERVICE）'獲得它每次 –
