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：
