创建自定义通知,android

Question

我想在此图片中创建一个类似红色边框通知的通知:

我知道如何在此图像中创建普通通知,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.

Answer 1

在通知中添加RemoteView这是Sample

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()); 

widget.xml

<?xml version="1.0" encoding="UTF-8"?>
<LinearLayout
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    android:gravity="center"
    android:orientation="horizontal">
    <TextView
        android:id="@+id/textView1"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:gravity="center"
        android:text="DJ notification"
        android:textAppearance="?android:attr/textAppearanceMedium" />
    <Button
        android:id="@+id/button1"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="Close Me" />
</LinearLayout>

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> = 4.1的设备上运行,则会使用新功能,如果在Android <4.1上运行,则通知将是一个简单的旧通知.

从Android 4.1开始,可以使用扩展通知来处理这些情况.如果您正在使用Notification.Builder或NotificationCompat.Builder,则可以为扩展通知设置常规Builder和单独Builder使用NotificationCompat.InboxStyle或使用其他样式之一,并将两者连接起来.
