我有一个应用程序,提醒人们完成他们的任务.所以有一个PendingIntent,现在用户可以在他想要的时候删除警报.在这段代码中,只有一个PendingIntent用于多个用户警报,因此我对取消意图附加功能的特定警报感到困惑"pill".其余警报不应取消.我对这个问题一无所知.希望我很清楚.谢谢
Intent intent = new Intent(this, AlarmNotifyReceiver.class);
intent.putExtra("Name_pill", "pill");
sender = PendingIntent.getBroadcast(this,
DatabaseConstants.NOTIFICATION_ID + 1, intent,
PendingIntent.FLAG_UPDATE_CURRENT);
AlarmManager am = (AlarmManager) getSystemService(ALARM_SERVICE);
am.set(AlarmManager.RTC_WAKEUP,cal.getTimeInMillis(), sender);
updateTheFlag(pillName[(pillName.length-1)]);
Run Code Online (Sandbox Code Playgroud) 我正在尝试开发一个简单的Android Wear应用程序,但我遇到了问题:
导入android.support.wearable无法解析
我创建了一个这样的通知频道:
NotificationChannel channel = new NotificationChannel(CHANNEL_ID_FOOBAR, getContext().getString(R.string.notification_channel_foobar), NotificationManager.IMPORTANCE_DEFAULT);
notificationManager.createNotificationChannel(channel);
Run Code Online (Sandbox Code Playgroud)
我为R.string.notification_channel_foobar提供了不同的翻译,并且使用创建时使用的语言创建了频道,因此如果我最终更改了设备的语言,那么该频道将保留旧语言.有没有办法克服这个问题,或者这是一个限制,即通过设计?
Activity 在应用程序运行时更改系统字体时重新启动.
有什么方法可以避免重启我的Activity?我用基本的"Hello World"应用程序测试了它.
我使用Android 4.1作为目标
PS:我尝试过使用android:configChanges但没有任何与字体更改相关的标志.
出于某些原因,我必须在我的应用程序上禁用多点触控功能.用户一次只能按一个按钮,否则应用程序会崩溃.有没有办法实现这个要求?
非常感谢!

根据文档,此代码应等待最多 60 秒以使监视器被击中。如果它被击中,活动将被返回(否则为空)。
发生的情况是,测试时不时会通过,但大多数时候它会失败,因为a == null. 我正在观察测试用例,我可以清楚地看到它没有等待 60 秒。只有一点。通过一些打印输出,我还注意到监视器实际上被击中了,但返回的活动getLastActivity()仍然是null。
1)这怎么可能?
2)我可以做些什么来避免它?
