different views on a single list ( Android )
Is there a way to make a list with different views? I mean that row in posiotion开发者_JS百科 X will have layout "X.xml" and row number Z will have layout "Y.xml"?
I've tried to manipulate ListRowAdapter() and getView() in a few ways but with no success...
Hi, Is there a way to make a list with different views? I mean that row in posiotion X will have layout "X.xml" and row number Z will have layout "Y.xml"?
Sure.
Step #1: Create an Adapter
class, by extending BaseAdapter
, ArrayAdapter
, CursorAdapter
, etc.
Step #2: Implement getViewTypeCount()
to return how many different row types there are
Step #3: Implement getItemViewType()
to return a number between 0
and the value returned by getViewTypeCount()
, indicating which row type a given position will use
Step #4: Override getView()
(or newView()
and bindView()
for CursorAdapter
) and have it create the right row
I don't think there is an easy way to do it out of the box. Depending on how different your layouts are, you might be able to come up with a single layout, and then show or hide elements of it in getView depending on the row. If you set an item to Layout.GONE, its as if it isn't there.
I solved it in another way: in the ListRowAdapter -> getView() I've made an if() statement on the inflater:
LayoutInflater inflater=context.getLayoutInflater();
View row=inflater.inflate(R.layout.X, null);
if(somthing)
{
row=inflater.inflate(R.layout.Y, null);
//whatever
}
and in the end: return row;
works like a charm :)
