I'm trying to implement a Gallery that every cell is a fragment.

gallery_item.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" />

getView() of GalleryAdapter (extends 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;
}

It's working, but the problem is that the gallery called getView() in infinite loop.

It's look like a onMeasure issue, here is the stack:

    Fragments aren't designed to be used as children in views that recycle them. I advise you to rethink your current logic and avoid using fragments as children for that gallery(which you should also avoid as it's deprecated). – user May 06 '13 at 07:45
  • 10x @Luksprog .I know that Gallery is deprecated, but still can't find any alternative for the effect of Gallery that shows part of the items from left and right, do you have any suggestions? – David May 06 '13 at 09:19
  • Unfortunately I don't know a library to recommend as a gallery replacement. – user May 06 '13 at 12:49

A single column GridView can be used as a Gallery substitute
