将两个Listview合并为一个带有标头的Listview

// 创建一个自定义的数据结构，用于表示每个ListView的数据
class ListViewData {
    String title;
    List<String> data;

    ListViewData(String title, List<String> data) {
        this.title = title;
        this.data = data;
    }
}

// 创建一个自定义的Adapter
class CustomAdapter extends BaseAdapter {
    List<ListViewData> dataList;

    CustomAdapter(List<ListViewData> dataList) {
        this.dataList = dataList;
    }

    @Override
    public int getCount() {
        return dataList.size();
    }

    @Override
    public Object getItem(int position) {
        return dataList.get(position);
    }

    @Override
    public long getItemId(int position) {
        return position;
    }

    @Override
    public View getView(int position, View convertView, ViewGroup parent) {
        // 创建并初始化视图
        if (convertView == null) {
            LayoutInflater inflater = LayoutInflater.from(parent.getContext());
            convertView = inflater.inflate(android.R.layout.simple_list_item_1, parent, false);
        }

        // 获取当前位置的数据
        ListViewData listViewData = dataList.get(position);

        // 设置标题和数据到视图
        TextView textView = convertView.findViewById(android.R.id.text1);
        textView.setText(listViewData.title + ": " + listViewData.data.get(0));

        return convertView;
    }
}

// 创建两个ListView的数据
List<String> data1 = Arrays.asList("Data 1-1", "Data 1-2", "Data 1-3");
List<String> data2 = Arrays.asList("Data 2-1", "Data 2-2", "Data 2-3");

// 创建合并后的数据
List<ListViewData> mergedData = new ArrayList<>();
mergedData.add(new ListViewData("List 1", data1));
mergedData.add(new ListViewData("List 2", data2));

// 创建新的ListView和自定义的Adapter
ListView mergedListView = new ListView(context);
CustomAdapter adapter = new CustomAdapter(mergedData);

// 设置Adapter给ListView
mergedListView.setAdapter(adapter);
