我知道如何创建正常的通知，例如此图像中带有蓝色边框的通知，但是我想显示一个图标，以及附近的三行信息。我怎样才能做到这一点？任何建议将不胜感激。

Answer 1

添加RemoteViews通知。这是一个示例：var remoteViews = new RemoteViews(getPackageName(), R.layout.widget);var mBuilder = new NotificationCompat.Builder(this)&nbsp; &nbsp; .setSmallIcon(R.drawable.ic_launcher)&nbsp; &nbsp; .setContent(remoteViews);// Creates an explicit intent for an Activity in your appIntent 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 stackstackBuilder.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());&nbsp;widget.xml<?xml version="1.0" encoding="UTF-8"?><LinearLayout&nbsp; &nbsp; xmlns:android="http://schemas.android.com/apk/res/android"&nbsp; &nbsp; android:layout_width="fill_parent"&nbsp; &nbsp; android:layout_height="fill_parent"&nbsp; &nbsp; android:gravity="center"&nbsp; &nbsp; android:orientation="horizontal">&nbsp; &nbsp; <TextView&nbsp; &nbsp; &nbsp; &nbsp; android:id="@+id/textView1"&nbsp; &nbsp; &nbsp; &nbsp; android:layout_width="wrap_content"&nbsp; &nbsp; &nbsp; &nbsp; android:layout_height="wrap_content"&nbsp; &nbsp; &nbsp; &nbsp; android:gravity="center"&nbsp; &nbsp; &nbsp; &nbsp; android:text="DJ notification"&nbsp; &nbsp; &nbsp; &nbsp; android:textAppearance="?android:attr/textAppearanceMedium" />&nbsp; &nbsp; <Button&nbsp; &nbsp; &nbsp; &nbsp; android:id="@+id/button1"&nbsp; &nbsp; &nbsp; &nbsp; android:layout_width="wrap_content"&nbsp; &nbsp; &nbsp; &nbsp; android:layout_height="wrap_content"&nbsp; &nbsp; &nbsp; &nbsp; android:text="Close Me" /></LinearLayout>&nbsp;检查这篇文章还有更多的样式可供选择Android开发人员编辑：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可用的功能。如果您的应用程序在Android> = 4.1的设备上运行，则将使用新功能；如果在Android <4.1的设备上运行，则通知将是简单的旧通知。对于<11 API，请使用http://www.framentos.com/zh-CN/android-tutorial/2012/02/20/how-to-create-a-custom-notification-on-android/

从Android 4.1开始，可以使用扩展的通知来处理这些情况。如果您使用Notification.Builder或NotificationCompat.Builder，则可以使用或其他样式之一为展开的通知设置普通样式和Builder单独样式，然后将两者连接起来。BuilderNotificationCompat.InboxStyle
