    这里我附上了截图，第一个屏幕内容是帖子的标题，当我们点击应用名称右侧的向下箭头时，它会导致第二个截图，即推送通知的自定义布局。以下是示例布局我为我设计的。
  
   <pre>
 <code>
 <?xml version="1.0" encoding="utf-8"?>
<LinearLayout
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_margin="4dp"
xmlns:card_view="http://schemas.android.com/apk/res-auto"
android:orientation="vertical"
card_view:cardCornerRadius="5dp"
card_view:cardUseCompatPadding="true">

</code>
 </pre>
  
    使用自定义布局创建通知的方法，
  
   <pre>
 <code>
 public static void createNotification(String title, String body,String image_url, Context context, int notificationsId, String single_id) {
 Intent notificationIntent;

long when = System.currentTimeMillis();
    int id = (int) System.currentTimeMillis();

Bitmap bitmap = getBitmapFromURL(image_url);
    NotificationCompat.BigPictureStyle notifystyle = new NotificationCompat.BigPictureStyle();
    notifystyle.bigPicture(bitmap);
    RemoteViews contentView = new RemoteViews(context.getPackageName(), R.layout.custom_notification_layout);
    contentView.setImageViewBitmap(R.id.image, bitmap);
    contentView.setTextViewText(R.id.title, body);

NotificationCompat.Builder mBuilder = new NotificationCompat.Builder(context)
            .setSmallIcon(R.drawable.ic_launcher)
            .setStyle(notifystyle)
            .setCustomBigContentView(contentView)
            .setContentText(body);
    NotificationManager mNotificationManager = (NotificationManager) context
            .getSystemService(Context.NOTIFICATION_SERVICE);

notificationIntent = new Intent(context, SinglePost.class);
    notificationIntent.putExtra("single_id",single_id);
    notificationIntent.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP | Intent.FLAG_ACTIVITY_NEW_TASK);
    PendingIntent contentIntent = PendingIntent.getActivity(context, id, notificationIntent, 0);

Notification notification = mBuilder.build();
    notification.contentIntent = contentIntent;
    notification.flags |= Notification.FLAG_AUTO_CANCEL;
    notification.defaults |= Notification.DEFAULT_SOUND;
    notification.defaults |= Notification.DEFAULT_VIBRATE;

mNotificationManager.notify(notificationsId, notification);

}

public static Bitmap getBitmapFromURL(String strURL) {
    try {
        URL url = new URL(strURL);
        HttpURLConnection connection = (HttpURLConnection) url.openConnection();
        connection.setDoInput(true);
        connection.connect();
        InputStream input = connection.getInputStream();
        Bitmap myBitmap = BitmapFactory.decodeStream(input);
        return myBitmap;
    } catch (IOException e) {
        e.printStackTrace();
        return null;
    }
}

 </pre>

<div class =“post-text”itemprop =“text”>
  
    首先为您的通知创建一个xml。
  
  
    的
      custom_notification.xml：
    </强>
  
   <pre>
 <code>
 <RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
 android:id="@+id/layout"
 android:layout_width="fill_parent"
 android:layout_height="fill_parent"
 android:padding="10dp" >
 <ImageView android:id="@+id/image"
 android:layout_width="wrap_content"
 android:layout_height="fill_parent"
 android:layout_alignParentLeft="true"
 android:layout_marginRight="10dp" />
 <TextView android:id="@+id/title"
 android:layout_width="wrap_content"
 android:layout_height="wrap_content"
 android:layout_toRightOf="@id/image"
 style="Custom Notification Title" />
 <TextView android:id="@+id/text"
 android:layout_width="wrap_content"
 android:layout_height="wrap_content"
 android:layout_toRightOf="@id/image"
 android:layout_below="@id/title"
 style="Custom Notification Text" />
</RelativeLayout>

</code>
 </pre>
  
    的
      现在java代码：
    </强>
  
   <pre>
 <code>
 public class MainActivity extends Activity {

@SuppressWarnings("deprecation")
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

int icon = R.drawable.ic_launcher;
        long when = System.currentTimeMillis();
        Notification notification = new Notification(icon, "Custom Notification", when);

NotificationManager mNotificationManager = (NotificationManager)getSystemService(NOTIFICATION_SERVICE);

RemoteViews contentView = new RemoteViews(getPackageName(), R.layout.custom_notification);
        contentView.setImageViewResource(R.id.image, R.drawable.ic_launcher);
        contentView.setTextViewText(R.id.title, "Custom notification");
        contentView.setTextViewText(R.id.text, "This is a custom layout");
        notification.contentView = contentView;

Intent notificationIntent = new Intent(this, MainActivity.class);
        PendingIntent contentIntent = PendingIntent.getActivity(this, 0, notificationIntent, 0);
        notification.contentIntent = contentIntent;

notification.flags |= Notification.FLAG_NO_CLEAR; //Do not clear the notification
        notification.defaults |= Notification.DEFAULT_LIGHTS; // LED
        notification.defaults |= Notification.DEFAULT_VIBRATE; //Vibration
        notification.defaults |= Notification.DEFAULT_SOUND; // Sound

mNotificationManager.notify(1, notification);
    }

@Override
    public boolean onCreateOptionsMenu(Menu menu) {
        getMenuInflater().inflate(R.menu.activity_main, menu);
        return true;
    }
}

     您可以使用
     <code>
 NotificationCompat.Builder
 </code>
     用于创造
     <code>
 Notification
 </code>
     实例如下：
  
   <pre>
 <code>
 NotificationCompat.Builder notificationBuilder = new NotificationCompat.Builder(this)
 .setSmallIcon(icon)
 .setContent(contentView)
 .setContentTitle("Custom Notification")
 .setWhen(when);
...
mNotificationManager.notify(1, notificationBuilder.build());

</code>
 </pre>
</DIV>
