Java 布局不'；不显示视图的第一项

我从parse数据库下载图片和名称，并创建一个cardstack。每个视图都有一个名称和一张图片，但我看不到视图的第一张图片（位置0），直到我使用向左滑动或向右滑动按钮（然后我看到它向外滑动），nameAgeLabel工作正常

你有什么主意我怎么修吗？没有什么应该重叠它，我一次又一次地检查，但可能我忽略了关于适配器中位置0的一些特殊内容。数据也应该是良好的，否则nameAgeLabel将无法工作

我可以删除content.xml中的一些布局，但这也没用

编辑：我现在只在日志中获取第一次查看的信息：

您在DeckSwipe的布局中使用swipedeck:max_visible=“1”，这就是为什么它是库中的一个bug。尝试将可见的最大值增加到2或3，这样对您来说效果会很好

如果您只需要显示一张卡，您可以修改库中的SwipeDeck.java并替换setAdapter函数，如下所示：

public void setAdapter(final Adapter adapter) 
{
        if (adapter == null)
            return;

        if (this.mAdapter != null) {
            this.mAdapter.unregisterDataSetObserver(observer);
        }
        mHasStableIds = adapter.hasStableIds();
        mAdapter = adapter;
        .
        .
        .
        adapter.registerDataSetObserver(observer);
        if (deck.size() > 0)
            addNextView();
        removeAllViewsInLayout();
        requestLayout();
    }

public void setAdapter(final Adapter adapter) 
{
        if (adapter == null)
            return;

        if (this.mAdapter != null) {
            this.mAdapter.unregisterDataSetObserver(observer);
        }
        mHasStableIds = adapter.hasStableIds();
        mAdapter = adapter;
        .
        .
        .
        adapter.registerDataSetObserver(observer);
        if (deck.size() > 0)
            addNextView();
        removeAllViewsInLayout();
        requestLayout();
    }
