如何创建不同类型组件的ListView并访问它们

public class ListItem {
    public static final int TYPE_TEXT = 0;
    public static final int TYPE_IMAGE = 1;

    private int type;
    private String content;

    public ListItem(int type, String content) {
        this.type = type;
        this.content = content;
    }

    public int getType() {
        return type;
    }

    public String getContent() {
        return content;
    }
}

public class MultiTypeAdapter extends BaseAdapter {
    private List<ListItem> items;

    public MultiTypeAdapter(List<ListItem> items) {
        this.items = items;
    }

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

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

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

    @Override
    public View getView(int position, View convertView, ViewGroup parent) {
        ListItem item = items.get(position);
        if (item.getType() == ListItem.TYPE_TEXT) {
            return createTextView(parent, item.getContent());
        } else if (item.getType() == ListItem.TYPE_IMAGE) {
            return createImageView(parent, item.getContent());
        }
        return null;
    }

    private View createTextView(ViewGroup parent, String text) {
        TextView textView = new TextView(parent.getContext());
        textView.setText(text);
        return textView;
    }

    private View createImageView(ViewGroup parent, String imageUrl) {
        ImageView imageView = new ImageView(parent.getContext());
        // 这里可以使用Glide或Picasso加载图片
        Glide.with(parent.getContext()).load(imageUrl).into(imageView);
        return imageView;
    }
}

public class MainActivity extends AppCompatActivity {
    private ListView listView;
    private MultiTypeAdapter adapter;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        listView = findViewById(R.id.listView);
        List<ListItem> items = new ArrayList<>();
        items.add(new ListItem(ListItem.TYPE_TEXT, "Hello World"));
        items.add(new ListItem(ListItem.TYPE_IMAGE, "https://example.com/image.jpg"));

        adapter = new MultiTypeAdapter(items);
        listView.setAdapter(adapter);
    }
}
