直播平台源码，各个样式的消息通知栏显示方式

1、浮动通知

    /**<br>     * 浮动通知 在[5.0,8.0)的系统中浮动通知的产生条件<br>     * 是NotificationCompat.Builder中设置setPriority()的参数<br>     * 必须在NotificationCompat.PRIORITY_HIGH及以上并且有铃声或者震动才能有效果<br>     * 但在[8.0，8.0+)的时候因为NotificationChannel中的设置高于一切 所以<br>     * NotificationChannel中的importance必须要在NotificationManager.IMPORTANCE_HIGH及以上(!注意 此时会有默认的铃声和震动的效果哦～)<br>     * 5.0以下的系统就不支持啦<br>     *<br>     * @param noticationId<br>     * @param pendingIntent<br>     * @param largeIcon<br>     * @param smallIcon<br>     * @param ticker<br>     * @param subText<br>     * @param contentTitle<br>     * @param contentText<br>     * @param sound<br>     * @param vibrate<br>     * @param light<br>     */<br>    public void notifyHeadUp(int noticationId, PendingIntent pendingIntent, @DrawableRes int largeIcon, @DrawableRes int smallIcon, String ticker, String subText, String contentTitle, String contentText, boolean sound, boolean vibrate, boolean light) {<br> <br>        if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O) {<br>            if (notificationChannel.getImportance() < NotificationManager.IMPORTANCE_HIGH) {<br>                notificationChannel.setImportance(NotificationManager.IMPORTANCE_HIGH);<br>                notificationManager.createNotificationChannel(notificationChannel);<br>            }<br>        }<br>//        else if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP) {<br>//<br>//<br>//        }<br>        builderNotification(pendingIntent, largeIcon, smallIcon, ticker, subText, contentTitle, contentText, NotificationCompat.PRIORITY_HIGH, sound, vibrate, light);<br> <br> <br>        notifyNotification(noticationId);<br>    }

2、带进度条通知

    /**<br>     * 在5.0的系统以下没有进度条显示 8.0及以上显示进度条是没有铃声和震动的效果的<br>     *<br>     * @param noticationId<br>     * @param pendingIntent<br>     * @param largeIcon<br>     * @param smallIcon<br>     * @param ticker<br>     * @param subText<br>     * @param contentTitle<br>     * @param contentText<br>     * @param maxProgress<br>     * @param curProgress<br>     */<br>    public void notifyProgress(int noticationId, PendingIntent pendingIntent, @DrawableRes int largeIcon, @DrawableRes int smallIcon, String ticker, String subText, String contentTitle, String contentText, int maxProgress, int curProgress) {<br>        builderNotification(pendingIntent, largeIcon, smallIcon, ticker, subText, contentTitle, contentText, NotificationCompat.PRIORITY_HIGH, false, true, false);<br> <br>        if (curProgress >= maxProgress) {<br>            builder.setProgress(0, 0, false);<br>        } else {<br>            builder.setProgress(maxProgress, curProgress, false);<br>        }<br> <br> <br>        notifyNotification(noticationId);<br>    }

3、消息类通知

    /**<br>     * 发送一个消息类的通知7.0以上有效 7.0以下效果不友好<br>     *<br>     * @param noticationId<br>     * @param pendingIntent<br>     * @param largeIcon<br>     * @param smallIcon<br>     * @param ticker<br>     * @param subText<br>     * @param contentTitle<br>     * @param contentText<br>     * @param priority<br>     * @param sound<br>     * @param vibrate<br>     * @param light<br>     */<br>    public void notifyMessageType(int noticationId, PendingIntent pendingIntent, @DrawableRes int largeIcon, @DrawableRes int smallIcon, String ticker, String subText, String contentTitle, String contentText, int priority, boolean sound, boolean vibrate, boolean light) {<br> <br>        builderNotification(pendingIntent, largeIcon, smallIcon, ticker, subText, contentTitle, contentText, priority, sound, vibrate, light);<br> <br>        builder.setStyle(new NotificationCompat.MessagingStyle(contentTitle).setConversationTitle("xx")<br>                .addMessage(new NotificationCompat.MessagingStyle.Message(contentText, System.currentTimeMillis(), "wo")));<br> <br>        notifyNotification(noticationId);<br> <br>    }
