我正在从手表发送通知，并且我希望通知是可点击的，即点击时它会打开一个活动。这是它的样子

通知
（来源：macnn.com）

但是，我不想显示播放图标，只想要简单的通知外观。即使我设置了一个空的操作图标，图标空间仍然被占用，我无法将文本放入该空间。有没有办法释放图标空间以显示文本？

代码如下：

NotificationCompat.Builder builder = new NotificationCompat.Builder(this)
            .setSmallIcon(R.drawable.ic_launcher)
            .setContentTitle("Tracking")
            .setContentText("Tap to open.")
            .setLargeIcon(BitmapFactory.decodeResource(getResources(), R.drawable.launchbg))
            .setLocalOnly(true)
            .addAction(R.drawable.empty_icon, "blah", pendingSaveIntent)                 
            .extend(new NotificationCompat.WearableExtender()
                    .setContentAction(0));

setHintHideIcon(true)隐藏图标。

NotificationCompat.Builder builder = new NotificationCompat.Builder(this)
        .setSmallIcon(R.drawable.ic_launcher)
        .setContentTitle("Tracking")
        .setContentText("Tap to open.")
        .setLargeIcon(BitmapFactory.decodeResource(getResources(), R.drawable.launchbg))
        .setLocalOnly(true)
        .addAction(R.drawable.empty_icon, "blah", pendingSaveIntent)                 
        .extend(new NotificationCompat.WearableExtender()
                .setHintHideIcon(true)
                .setContentAction(0));

为了实现这一点，您必须创建一个自定义 RemotViews 对象并通过以下方式将自定义布局传递给通知：

RemoteViews remoteView = new RemoteViews("PACKAGENAMEWHERELAYOUTEXISTS", R.layout.custom_layout);
NotificationCompat.Builder builder = new NotificationCompat.Builder(this)
                         .setContent(remoteView);

看：

用于远程视图。

和设置内容：
