Question

我有3个测试设备。我无法在Android 6.0和4.3中显示自定义通知，而相同的代码就像5.1.1中的魅力一样

我真的厌倦了Android的兼容性困境。

这是我在Android 5.1.1中出现的自定义通知：

这是我的代码：

private void notification(Radio radio, int playPauseImage) {
    RemoteViews contentView = new RemoteViews(getPackageName(), R.layout.activity_notification);
    contentView.setImageViewResource(R.id.imgChannelLogo, Utils.getChannelLogoByPosition(currentRadioId));
    contentView.setTextViewText(R.id.txtChannelName, radio.getKanalAdi());
    contentView.setTextViewText(R.id.txtCategory, radio.getKategoriAdi());
    contentView.setImageViewResource(R.id.mediacontroller_previous, android.R.drawable.ic_media_rew);
    contentView.setImageViewResource(R.id.mediacontroller_play_pause, playPauseImage);
    contentView.setImageViewResource(R.id.mediacontroller_next, android.R.drawable.ic_media_ff);

    PendingIntent pendingPlayPauseIntent = PendingIntent.getBroadcast(this, 0, new Intent(PLAYPAUSE), 0);
    PendingIntent pendingNextIntent = PendingIntent.getBroadcast(this, 0, new Intent(NEXT), 0);
    PendingIntent pendingPreviousIntent = PendingIntent.getBroadcast(this, 0, new Intent(PREVIOUS), 0);
    PendingIntent pendingCloseIntent = PendingIntent.getBroadcast(this, 0, new Intent(CLOSE), 0);

    contentView.setOnClickPendingIntent(R.id.mediacontroller_play_pause, pendingPlayPauseIntent);
    contentView.setOnClickPendingIntent(R.id.mediacontroller_next, pendingNextIntent);
    contentView.setOnClickPendingIntent(R.id.mediacontroller_previous, pendingPreviousIntent);
    contentView.setOnClickPendingIntent(R.id.imgClose, pendingCloseIntent);

    NotificationCompat.Builder notificationBuilder = new NotificationCompat.Builder(this)
            .setSmallIcon(R.drawable.ic_status)
            .setLargeIcon(BitmapFactory.decodeResource(getResources(), R.mipmap.ic_launcher))
            .setContent(contentView)
            .setWhen(System.currentTimeMillis())
            .setTicker(getText(R.string.ticker));

    notificationBuilder.mNotification.bigContentView = contentView;

    startForeground(1337, notificationBuilder.mNotification);
}

导致崩溃的异常：

FATAL EXCEPTION: main
Process: com.mypackage.myapp, PID: 12134

我还提供了我的通知XML布局：

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="176dp"

            android:onClick="nextChannel"
            android:scaleType="fitCenter" />

    </RelativeLayout>
</LinearLayout>

那我的实施中的问题在哪里？我知道我必须只使用RemoteView中的一些组件，但我认为没有不合适的组件。任何建议将不胜感激。

Answer 1

我解决了自己的问题。

根据this answer，我删除了ImageButtons中的android:onClick属性。然后它适用于我的所有设备。

Answer 2

通知的必填字段是

小图标
内容标题
内容文字

您缺少内容标题和内容文字。

当然，如果您要制作媒体通知，则应使用NotificationCompat.MediaStyle而不是构建自定义通知。

自定义通知布局在Android 6.0和4.3上都崩溃了
