Android ListView fixed height item

ListViewHeight.java

short answer:

when inflating for convertView, instead of just

result = inf.inflate(R.layout.thread_item, null);
do

result = inf.inflate(R.layout.thread_item, parent, false);
explanation:

the method in question is

inflater.inflate(int viewId, ViewGroup parent, boolean attachToRoot)
because you're not honoring the supplied parent (which in this case is the ListView), whatever dimension you supply to the listview item will by default be set to layout_width=fill_parent, layout_height=wrap_content, ignoring the 300dip height you specified in xml. supplying the parent view, and passing false will honor the 300dip height, while telling the inflater to not attach it to the root (parent), which the listview should be doing automagically by itself.
