说明：MyListFragment是自定义的ListFragment。它使用了list_fragment.xml作为布局，并通过android.R.layout.simple_list_item_1显示ListView中的每一项。
4. list_fragment.xml的内容
<?xml version="1.0" encoding="utf-8"?> <LinearLayout xmlns:android="http://www.easck.com/apk/res/android" android:layout_width="match_parent" android:layout_height="match_parent" android:orientation="vertical" > <!-- ListFragment对应的android:id值固定为"@id/android:list" --> <ListView android:id="@id/android:list" android:layout_width="match_parent" android:layout_height="match_parent" android:drawSelectorOnTop="false" /> </LinearLayout>
"Activity的布局以及代码"和前面一样，这里就不再重复说明。
5. MyListFragment的内容
public class MyListFragment extends ListFragment {
private static final String TAG = "##MyListFragment##";
private ListView selfList;
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
Log.d(TAG, "onCreateView");
return inflater.inflate(R.layout.list_fragment, container, false);
}
@Override
public void onCreate(Bundle savedInstanceState) {
final String[] from = new String[] {"title", "info"};
final int[] to = new int[] {R.id.text1, R.id.text2};
Log.d(TAG, "onCreate");
super.onCreate(savedInstanceState);
// 建立SimpleAdapter，将from和to对应起来
SimpleAdapter adapter = new SimpleAdapter(
this.getActivity(), getSimpleData(),
R.layout.item, from, to);
this.setListAdapter(adapter);
}
public void onListItemClick(ListView parent, View v,
int position, long id) {
Log.d(TAG, "onListItemClick");
Toast.makeText(getActivity(),
"You have selected " + position,
Toast.LENGTH_SHORT).show();
}
private List<Map<String, Object>> getSimpleData() {
List<Map<String, Object>> list = new ArrayList<Map<String, Object>>();
Map<String, Object> map = new HashMap<String, Object>();
map.put("title", "Ferris wheel");
map.put("info", "Suzhou Ferris wheel");
list.add(map);
map = new HashMap<String, Object>();
map.put("title", "Flower");
map.put("info", "Roser");
list.add(map);
map = new HashMap<String, Object>();
map.put("title", "Disk");
map.put("info", "Song Disk");
list.add(map);
return list;
}
}
