Android 中不显示自定义通知

Question

您好，我正在我的 Android 应用程序中显示自定义通知。但问题是自定义通知未显示。我看到了很多帖子，但没有找到与我的问题相关的任何答案。

我找不到问题出在哪里。你能看一下这个吗？

PendingIntent pendingIntent = PendingIntent.getActivity(context, 0, intent, 0);

// display the notification
NotificationManager mNotificationManager = (NotificationManager)context.getSystemService(Context.NOTIFICATION_SERVICE);

RemoteViews contentView = new RemoteViews(getPackageName(), R.layout.custom_notification);
contentView.setImageViewResource(R.id.notificationIcon, Util.notificationBitmap);
contentView.setTextViewText(R.id.notificationTitle, Util.notificationTitle);
contentView.setTextViewText(R.id.notificationContent, notificationMessage);

NotificationCompat.Builder mBuilder = new NotificationCompat.Builder(context)
                    .setSmallIcon(R.drawable.ic_stat_logo)
                    .setContentTitle(Util.notificationTitle)
                    .setStyle(new NotificationCompat.BigTextStyle()
                    .bigText(notificationMessage))
                    .setAutoCancel(true)
                    .setDefaults(Notification.DEFAULT_SOUND)
                    .setContentText(notificationMessage);

mBuilder.setContent(contentView);
// build notification
mBuilder.setContentIntent(pendingIntent);
mNotificationManager.notify((int)SystemClock.currentThreadTimeMillis(), mBuilder.build());

自定义通知.xml

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent" >

    <ImageView
        android:id="@+id/notificationIcon"
        android:layout_width="wrap_content"
        android:layout_height="match_parent"
        />

    <TextView
        android:id="@+id/notificationTitle"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_toRightOf="@id/notificationIcon"
        android:textAppearance="?android:attr/textAppearanceMedium" />

    <TextView
        android:id="@+id/notificationContent"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_below="@id/notificationTitle"
        android:layout_toRightOf="@id/notificationIcon"
        android:textAppearance="?android:attr/textAppearanceSmall" />

</RelativeLayout>

提前致谢。

更改布局以使用 LinearLayout。遇到了同样的问题，这是一个很好的解决方法。
