如何在使用Android FirebaseListAdapter时使用两种布局？

public class CustomFirebaseListAdapter extends FirebaseListAdapter<DataModel> {
    private static final int TYPE_LAYOUT1 = 0;
    private static final int TYPE_LAYOUT2 = 1;

    public CustomFirebaseListAdapter(Context context, Query query) {
        super(context, DataModel.class, R.layout.layout_item1, query);
    }

    @Override
    public int getItemViewType(int position) {
        DataModel data = getItem(position);
        if (data.getType().equals("type1")) {
            return TYPE_LAYOUT1;
        } else {
            return TYPE_LAYOUT2;
        }
    }

    @Override
    public int getViewTypeCount() {
        return 2; // 返回布局类型的数量
    }

    @Override
    protected void populateView(View v, DataModel model, int position) {
        int viewType = getItemViewType(position);
        if (viewType == TYPE_LAYOUT1) {
            // 使用布局1
            ViewHolder1 holder1 = (ViewHolder1) v.getTag();
            if (holder1 == null) {
                holder1 = new ViewHolder1();
                holder1.textView1 = (TextView) v.findViewById(R.id.text1);
                // 其他控件的初始化
                v.setTag(holder1);
            }
            // 设置布局1中的内容
            holder1.textView1.setText(model.getText());
            // 其他控件的设置
        } else {
            // 使用布局2
            ViewHolder2 holder2 = (ViewHolder2) v.getTag();
            if (holder2 == null) {
                holder2 = new ViewHolder2();
                holder2.textView2 = (TextView) v.findViewById(R.id.text2);
                // 其他控件的初始化
                v.setTag(holder2);
            }
            // 设置布局2中的内容
            holder2.textView2.setText(model.getText());
            // 其他控件的设置
        }
    }

    private static class ViewHolder1 {
        TextView textView1;
        // 其他控件的声明
    }

    private static class ViewHolder2 {
        TextView textView2;
        // 其他控件的声明
    }
}
