ListView


open class ListView : AbsListView
kotlin.Any
   ↳ android.view.View
   ↳ android.view.ViewGroup
   ↳ android.widget.AdapterView<android.widget.ListAdapter>
   ↳ android.widget.AbsListView
   ↳ android.widget.ListView

Displays a vertically-scrollable collection of views, where each view is positioned immediatelybelow the previous view in the list. For a more modern, flexible, and performant approach to displaying lists, use androidx.recyclerview.widget.RecyclerView.

To display a list, you can include a list view in your layout XML file:

<ListView
       android:id="@+id/list_view"
       android:layout_width="match_parent"
       android:layout_height="match_parent" />

A list view is an adapter view that does not know the details, such as type and contents, of the views it contains. Instead list view requests views on demand from a ListAdapter as needed, such as to display new views as the user scrolls up or down.

In order to display items in the list, call setAdapter(android.widget.ListAdapter) to associate an adapter with the list. For a simple example, see the discussion of filling an adapter view with text in the Layouts guide.

To display a more custom view for each item in your dataset, implement a ListAdapter. For example, extend BaseAdapter and create and configure the view for each data item in getView(...):

private class MyAdapter extends BaseAdapter {
 
       // override other abstract methods here
 
       @Override
       public View getView(int position, View convertView, ViewGroup container) {
           if (convertView == null) {
               convertView = getLayoutInflater().inflate(R.layout.list_item, container, false);
           }
 
           ((TextView) convertView.findViewById(android.R.id.text1))
                   .setText(getItem(position));
           return convertView;
       }
   }

ListView attempts to reuse view objects in order to improve performance and avoid a lag in response to user scrolls. To take advantage of this feature, check if the convertView provided to getView(...) is null before creating or inflating a new view object.

To specify an action when a user clicks or taps on a single list item, see Handling click events.

To learn how to populate a list view with a CursorAdapter, see the discussion of filling an adapter view with text in the Layouts guide. See Using a Loader to learn how to avoid blocking the main thread when using a cursor.

Note, many examples use ListActivity or ListFragment to display a list view. Instead, favor the more flexible approach when writing your own app: use a more generic Activity subclass or Fragment subclass and add a list view to the layout or view hierarchy directly. This approach gives you more direct control of the list view and adapter.
