我正在尝试实现一个画廊，每个单元格都是一个片段。

画廊项目.xml：

<?xml version="1.0" encoding="utf-8"?>
<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@+id/cardContainer"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="@drawable/img1" />

GalleryAdapter 的 getView()（扩展 BaseAdapter）：

public View getView(int position, View convertView, ViewGroup parent) 
{
    if (convertView == null) 
    {
        mHolder = new ViewHolder();
        mFrameLayout = (FrameLayout) LayoutInflater.from(parent.getContext()).inflate(R.layout.gallery_item, null);
        mFrameLayout.setPadding(25,0,25,0);
        //Add fragment to frame layout
        mFragmentManager.beginTransaction().add(mFrameLayout.getId(), new CardFrontFragment()).commit();

        convertView = mFrameLayout;
        mHolder.frameLayout = mFrameLayout;
        convertView.setTag(mHolder);
    } 
    else 
    {
        mHolder = (ViewHolder) convertView.getTag();
    }

    mHolder.frameLayout.setLayoutParams(new Gallery.LayoutParams(Gallery.LayoutParams.MATCH_PARENT, Gallery.LayoutParams.MATCH_PARENT));
    return mFrameLayout;
}

private static class ViewHolder {
    FrameLayout frameLayout;
}

它正在工作，但问题是画廊在无限循环中调用了 getView()。

它看起来像一个 onMeasure 问题，这里是堆栈：

10倍很多！

单列 GridView 可用作 Gallery 替代品
