处理@ layout / featured_content组件的类如下：

public class FeaturedContentView {
        @BindView(R.id.art)
        ImageView art;
        @BindView(R.id.shade)
        View shade;
        @BindView(R.id.title)
        TextView featuredTitle;
        @BindView(R.id.performer)
        TextView performer;
        @BindView(R.id.featured_title)
        KerningTextView featuredText;
        @BindView(R.id.play_button)
        Button play;
        @BindView(R.id.shareText)
        TextView shareText;
        @BindView(R.id.addToFavorites)
        ImageView addToFavs;

        FeaturedContentView(View view) {
            ButterKnife.bind(this,view);
        }
    }

我像这样膨胀布局：

if (viewstub != null) {
        View view = viewstub.inflate();
        featuredContentView = new FeaturedContentView(view);
}

上面的方法在我的片段中的两个不同的地方调用.它第一次正确膨胀但第二次引用java.lang.IllegalStateException失败：ViewStub必须具有非null的ViewGroup viewParent.

我该如何处理这种情况.
