我想在此图片中创建一个类似红色边框通知的通知:
我知道如何在此图片中创建普通通知,例如蓝色边框通知,但我想在其附近显示一个图标和大约3行信息。我怎样才能做到这一点?任何建议将不胜感激。

在通知中添加RemoteViews
。这是一个示例:
var remoteViews = new RemoteViews(getPackageName(), R.layout.widget);
var mBuilder = new NotificationCompat.Builder(this)
.setSmallIcon(R.drawable.ic_launcher)
.setContent(remoteViews);
// Creates an explicit intent for an Activity in your app
Intent resultIntent = new Intent(this, test.class);
// The stack builder object will contain an artificial back stack for
// the started Activity.
// This ensures that navigating backward from the Activity leads out of
// your application to the Home screen.
TaskStackBuilder stackBuilder = TaskStackBuilder.create(this);
// Adds the back stack for the Intent (but not the Intent itself)
stackBuilder.addParentStack(test.class);
// Adds the Intent that starts the Activity to the top of the stack
stackBuilder.addNextIntent(resultIntent);
PendingIntent resultPendingIntent = stackBuilder.getPendingIntent(0, PendingIntent.FLAG_UPDATE_CURRENT);
remoteViews.setOnClickPendingIntent(R.id.button1, resultPendingIntent);
var notificationManager = (NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);
// mId allows you to update the notification later on.
notificationManager.notify(100, mBuilder.build());

NotificationCompat.Builder是在所有Android版本上创建通知的最简单方法。您甚至可以使用Android 4.1提供的功能。如果您的应用在Android&gt; = 4.1的设备上运行,则会使用新功能,如果在Android&lt; 4.1上运行,通知将是一个简单的旧通知。

Expanded notifications可用于处理这些情况。如果您使用的是Notification.Builder
或NotificationCompat.Builder
,则可以使用Builder
或其中一个为扩展通知设置正常的Builder
和单独的NotificationCompat.InboxStyle
其他款式,并连接两个。
