Question

按钮在onclick处更改，这就是为什么有一个标志。但是警报管理器并没有停止意图，它甚至在onclick上也会一直运行以取消alarmManager

if (flag) {
    flag = false;
    imageButton.setImageResource(R.drawable.mybuttonbc);
    Intent intent = new Intent(HomeActivity.this, IntentServices.class);
    intent.setAction("upload");
    intent.putExtra("lat", lats);
    intent.putExtra("long", longs);

    final PendingIntent pintent = PendingIntent.getService(HomeActivity.this, 0, intent, PendingIntent.FLAG_UPDATE_CURRENT);
    AlarmManager alarm = (AlarmManager)getSystemService(Context.ALARM_SERVICE);
    alarm.setInexactRepeating(AlarmManager.RTC_WAKEUP, System.currentTimeMillis(), 60000, pintent);
    Snackbar.make(getWindow().getDecorView().getRootView(), "recording started!", Snackbar.LENGTH_LONG)
            .setAction("Action", null).show();

} else {
    flag = true;
    imagePanicButton.setImageResource(R.drawable.mybuttona);
    Intent intent = new Intent(HomeActivity.this, IntentServices.class);
    final PendingIntent pIntent = PendingIntent.getService(HomeActivity.this, 0, intent,   PendingIntent.FLAG_UPDATE_CURRENT);
    AlarmManager alarm = (AlarmManager)getSystemService(Context.ALARM_SERVICE);
    alarm.cancel(pIntent);
    Snackbar.make(getWindow().getDecorView().getRootView(), "recording stopped!", Snackbar.LENGTH_LONG)
            .setAction("Action", null).show();

}

您缺少用于最初创建警报的Intent中的操作。

只需将此行添加到取消警报的代码中：

intent.setAction("upload");

所以它看起来像这样：

if (flag) {
    flag = false;
    imageButton.setImageResource(R.drawable.mybuttonbc);
    Intent intent = new Intent(HomeActivity.this, IntentServices.class);
    intent.setAction("upload");
    intent.putExtra("lat", lats);
    intent.putExtra("long", longs);

    final PendingIntent pintent = PendingIntent.getService(HomeActivity.this, 0, intent, PendingIntent.FLAG_UPDATE_CURRENT);
    AlarmManager alarm = (AlarmManager)getSystemService(Context.ALARM_SERVICE);
    alarm.setInexactRepeating(AlarmManager.RTC_WAKEUP, System.currentTimeMillis(), 60000, pintent);
    Snackbar.make(getWindow().getDecorView().getRootView(), "recording started!", Snackbar.LENGTH_LONG)
            .setAction("Action", null).show();

} else {
    flag = true;
    imagePanicButton.setImageResource(R.drawable.mybuttona);
    Intent intent = new Intent(HomeActivity.this, IntentServices.class);
    intent.setAction("upload"); // <-Added
    final PendingIntent pIntent = PendingIntent.getService(HomeActivity.this, 0, intent,   PendingIntent.FLAG_UPDATE_CURRENT);
    AlarmManager alarm = (AlarmManager)getSystemService(Context.ALARM_SERVICE);
    alarm.cancel(pIntent);
    Snackbar.make(getWindow().getDecorView().getRootView(), "recording stopped!", Snackbar.LENGTH_LONG)
            .setAction("Action", null).show();

}

警报管理器调用意图服务，在点击按钮后，它应该取消，但警报管理器会一直触发服务
