我遇到了多种解决方案，我如何取消未决意图但是无济于事。我也无法触发取消，其中我在一个点击功能中放置了代码。触发该功能的按钮是代码生成的。取消无法被解雇，它继续进入预期的接收者，这是我的代码：

要查看的区域是点击按钮和设置警报方法
中的取消代码答案 0 :(得分：0)
嗯，你现在拥有的代码肯定不会起作用：
PendingIntent.getBroadcast(getBaseContext(),count, getIntent(), 0).cancel();
在此处使用getIntent()正在使用Intent开始使用的Activity。
如果使用此PendingIntent：
PendingIntent pendingIntent =
PendingIntent.getBroadcast(getBaseContext(),count, intent, 0);
您应该使用以下方法取消它：
Intent i = new Intent(getBaseContext(), AlarmReceiver.class);
PendingIntent pendingIntent =
PendingIntent.getBroadcast(getBaseContext(), count, i, 0);
manager.cancel(pendingIntent);
pendingIntent.cancel();
如果这对您不起作用，则count的值可能不相同。两个调用中count的值必须相同。
