Java – Can ListView have two or more different types of row layouts in Android?

I now have a very simple ListView in a ListActivity that only displays a list of text values. Here is my current code :

public class InfoActivity extends ListActivity {

@Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);

List<String> values = new ArrayList<String>();
         loads up the values array here
        // ...

ArrayAdapter<String> adapter = new ArrayAdapter<String>(this, android. R.layout.simple_list_item_1, values);
        setListAdapter(adapter);
    }

I

don’t have anything in the InfoActivity XML file because I’m using a ListActivity.

What I want to do is create a custom layout for the rows. The first 5 rows will contain layoutA.xml, and the last 5 lines will contain layoutB.xml.

What should I do? I don’t know where to start. Obviously, I’m looking for code that is as simple as possible.

It’s simple, you just need to extend the ArrayAdapter. My ArrayAdapter does two different things:

• My adapter takes a set of ResourceIds instead of passing a single ResourceId
• getView() checks the location and loads the appropriate resources

This is a simple example. If you intend to make it seem more complicated than the first half, and the second half is different, then you should cover it getViewTypeCount() and getItemViewType() .

Working example:

public class Example extends Activity {
    public class MyArrayAdapter<T> extends ArrayAdapter<T> {
        LayoutInflater mInflater;
        int[] mLayoutResourceIds;

public MyArrayAdapter(Context context, int[] textViewResourceId, List<T> objects) {
            super(context, textViewResourceId[0], objects);
            mInflater = (LayoutInflater)context.getSystemService (Context.LAYOUT_INFLATER_SERVICE);
            mLayoutResourceIds = textViewResourceId;
        }

@Override
        public View getView(int position, View convertView, ViewGroup parent) {
            if (convertView == null && position > 2)
                convertView = mInflater.inflate(mLayoutResourceIds[1], parent, false);
            return super.getView(position, convertView, parent);
        }
    }

@Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);

String[] array = new String[] {"one", "two", "three", "four", "five", "six"};
        List<String> list = new ArrayList<String>();
        Collections.addAll(list, array);

ListView listView = new ListView(this);
        listView.setAdapter(new MyArrayAdapter<String>(this, new int[] {android. R.layout.simple_list_item_1, android. R.layout.simple_list_item_single_choice}, list));
        setContentView(listView);
    }
}
