ListView的自定义适配器忽略设置值

Question

我将创建标签和图标的ListView。

这是我所做的：我创建了一个空白ListView，称为cardList。我创建了一个扩展了ArrayAdapter<String>的自定义视图我已经将cardList设置为该自定义视图：

cardList = findViewById(R.id.cards_list);
CustomView customView = new CustomView(this, names, images);
cardList.setAdapter(customView);

where

ListView cardList;
String[] names = {"Name1", "Name2", "Name3"};
Integer[] images = {R.drawable.image1, R.drawable.image2, R.drawable.image3};

CustomView类：

package ...

import ...

public class CustomView extends ArrayAdapter<String> {

    private String[] names;
    private Integer[] images;
    private Activity context;

    CustomView(Activity context, String[] names, Integer[] images) {
        super(context, R.layout.card_row, R.id.cardName, names);
        this.context = context;
        this.names = names;
        this.images = images;
    }

    @SuppressLint("InflateParams")
    @NonNull
    @Override
    public View getView(int position, @Nullable View convertView, @NonNull ViewGroup parent) {
        View r = convertView;
        ViewHolder viewHolder;
        if (r == null) {
            LayoutInflater layoutInflater = context.getLayoutInflater();
            r = layoutInflater.inflate(R.layout.card_row, null, true);
            viewHolder = new ViewHolder(r);
            r.setTag(viewHolder);
        } else {
            viewHolder = (ViewHolder) r.getTag();
        }
        viewHolder.name.setText(/*skipping: names[position]*/"Some text");
        viewHolder.name.setTypeface(Typeface.createFromAsset(AppName.assetManager, "fonts/prototype.ttf"));
        viewHolder.image.setImageResource(images[position]);
        return super.getView(position, convertView, parent);
    }

    class ViewHolder {
        TextView name;
        ImageView image;
        ViewHolder(View v) {
            name = v.findViewById(R.id.cardName);
            image = v.findViewById(R.id.symbolImg);
        }
    }
}

现在，我故意这样写viewHolder.name.setText(/*skipping: names[position]*/"Some text");行。结果是，尽管方法ListView应该对此进行更改，但我的setText("Some text")仍以数组中的名称显示，并且没有图标和自定义字体。因此，问题出在这部分：

viewHolder.name.setText(/*skipping: names[position]*/"Some text");
viewHolder.name.setTypeface(Typeface.createFromAsset(AppName.assetManager, "fonts/prototype.ttf"));
viewHolder.image.setImageResource(images[position]);

调试已显示该应用程序通过了本节，但是应忽略其中应设置的所有内容。我想念什么吗？

当您从getView而不是您的父视图返回父视图时，您的自定义视图将被忽略>

使用

return r;
代替

return super.getView(position, convertView, parent);
