I use an adapter to set the item layout and to populate a ListView
from a JSON string. Sometimes this JSON is empty and there aren't any rows into the ListView
and it's full blank.
In this case, I want to change the view and pass another layout showing "There aren't any rows here".
So this is my code:
MainActivity.java
public class MainActivity extends Activity {
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
ListView listView = (ListView) findViewById(R.id.listView);
List list = new LinkedList();
[...fill list...]
ListAdapter adapter = new ListAdapter(this, R.layout.list_row_layout, list, R.id.edCod, R.id.edDes);
listView.setAdapter(adapter);
}
}
ListAdapter.java
public class ListAdapter extends ArrayAdapter<Adapter> {
private LayoutInflater layoutInflater;
private int layout;
private int textCod;
private int textDes;
public FruttaAdapter(Context context, int layout, List<Adapter> objects, int textCod, int textDes) {
super(context, layout, objects);
this.layout = layout;
this.textCod = textCod;
this.textDes = textDes;
layoutInflater = LayoutInflater.from(context);
}

Actually, You could use a ListActivity or ListFragment and use its EmptyView
(any View which has the id android.R.id.empty)
