Java 共享图标（矢量）在设计中显示，但不在应用程序中显示

我已经使用vector在卡片视图中创建了一个共享图标

在HolderClass中实现

class CommasHolder extends RecyclerView.ViewHolder{
SimpleDraweeView commasImage;
ImageButton shareButton;

public CommasHolder(View cardView){
    super(cardView);
    commasImage = (SimpleDraweeView) cardView.findViewById(R.id.cardview_image);
    shareButton = (ImageButton) cardView.findViewById(R.id.share_button);
}
}

布局

    <ImageButton
        android:id="@+id/share_button"
        android:layout_width="30dp"
        android:layout_height="30dp"
        android:layout_marginRight="10dp"
        android:layout_gravity="bottom|end"
        card_view:srcCompat="@drawable/ic_share_black_24dp"/>

载体

<vector xmlns:android="http://schemas.android.com/apk/res/android"
    android:width="24dp"
    android:height="24dp"
    android:viewportWidth="24.0"
    android:viewportHeight="24.0">
<path
    android:fillColor="#FF000000"

您是否已将此添加到您的Gradle文件中

 android {  defaultConfig {  
 vectorDrawables.useSupportLibrary = true  
}   }

是的，我在gradle文件中添加了它
