看看这个项目：

祝你好运！

这是上面链接的项目源代码中的一个用法示例。

public class SectionListActivity extends Activity {



private class StandardArrayAdapter extends ArrayAdapter<SectionListItem> {



    private final SectionListItem[] items;



    public StandardArrayAdapter(final Context context,

            final int textViewResourceId, final SectionListItem[] items) {

        super(context, textViewResourceId, items);

        this.items = items;

    }



    @Override

    public View getView(final int position, final View convertView,

            final ViewGroup parent) {

        View view = convertView;

        if (view == null) {

            final LayoutInflater vi = (LayoutInflater) getSystemService(Context.LAYOUT_INFLATER_SERVICE);

            view = vi.inflate(R.layout.example_list_view, null);

        }

        final SectionListItem currentItem = items[position];

        if (currentItem != null) {

            final TextView textView = (TextView) view

                    .findViewById(R.id.example_text_view);

            if (textView != null) {

                textView.setText(currentItem.item.toString());

            }

        }

        return view;

    }

}



SectionListItem[] exampleArray = { // Comment to prevent re-format

new SectionListItem("Test 1 - A", "A"), //

        new SectionListItem("Test 2 - A", "A"), //

        new SectionListItem("Test 3 - A", "A"), //

        new SectionListItem("Test 4 - A", "A"), //

        new SectionListItem("Test 5 - A", "A"), //

        new SectionListItem("Test 6 - B", "B"), //

        new SectionListItem("Test 7 - B", "B"), //

        new SectionListItem("Test 8 - B", "B"), //

        new SectionListItem("Test 9 - Long", "Long section"), //

        new SectionListItem("Test 10 - Long", "Long section"), //

        new SectionListItem("Test 11 - Long", "Long section"), //

        new SectionListItem("Test 12 - Long", "Long section"), //

        new SectionListItem("Test 13 - Long", "Long section"), //

        new SectionListItem("Test 14 - A again", "A"), //

        new SectionListItem("Test 15 - A again", "A"), //

        new SectionListItem("Test 16 - A again", "A"), //

        new SectionListItem("Test 17 - B again", "B"), //

        new SectionListItem("Test 18 - B again", "B"), //

        new SectionListItem("Test 19 - B again", "B"), //

        new SectionListItem("Test 20 - B again", "B"), //

        new SectionListItem("Test 21 - B again", "B"), //

        new SectionListItem("Test 22 - B again", "B"), //

        new SectionListItem("Test 23 - C", "C"), //

        new SectionListItem("Test 24 - C", "C"), //

        new SectionListItem("Test 25 - C", "C"), //

        new SectionListItem("Test 26 - C", "C"), //

};



private StandardArrayAdapter arrayAdapter;



private SectionListAdapter sectionAdapter;



private SectionListView listView;



@Override

public void onCreate(final Bundle savedInstanceState) {

    super.onCreate(savedInstanceState);

    setContentView(R.layout.main);

    arrayAdapter = new StandardArrayAdapter(this, R.id.example_text_view,

            exampleArray);

    sectionAdapter = new SectionListAdapter(getLayoutInflater(),

            arrayAdapter);

    listView = (SectionListView) findViewById(getResources().getIdentifier(

            "section_list_view", "id",

            this.getClass().getPackage().getName()));

    listView.setAdapter(sectionAdapter);

}



@Override

public boolean onCreateOptionsMenu(Menu menu) {

    MenuInflater inflater = getMenuInflater();

    inflater.inflate(R.menu.test_menu, menu);

    return true;

}



@Override

public boolean onOptionsItemSelected(MenuItem item) {

    switch (item.getItemId()) {

    case R.id.standard_list:

        arrayAdapter = new StandardArrayAdapter(this,

                R.id.example_text_view, exampleArray);

        sectionAdapter = new SectionListAdapter(getLayoutInflater(),

                arrayAdapter);

        listView.setAdapter(sectionAdapter);

        return true;

    case R.id.empty_list:

        arrayAdapter = new StandardArrayAdapter(this,

                R.id.example_text_view, new SectionListItem[] {});

        sectionAdapter = new SectionListAdapter(getLayoutInflater(),

                arrayAdapter);

        listView.setAdapter(sectionAdapter);

        return true;

    default:

        return super.onOptionsItemSelected(item);

    }

}

这里使用的布局XML文件：

<?xml version="1.0" encoding="utf-8"?>

<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android" android:id="@+id/listView"

    android:orientation="vertical" android:layout_width="fill_parent" android:layout_height="fill_parent">

    <pl.polidea.sectionedlist.SectionListView android:id="@+id/section_list_view" android:layout_width="fill_parent"

            android:layout_height="fill_parent">

    </pl.polidea.sectionedlist.SectionListView>

</FrameLayout>
