無法解析方法“setText（模型）”

Question

我試圖讓網格視圖必須顯示文本，但我遇到了這個問題no suitable method found for setText(Model)我試圖對 listView 進行設置，但 go 不好，所以有人問我，這段代碼是我接觸到的最佳代碼它......直到現在......為什么它無法解析方法'setText（Model）'？

問題圖片

這是我的適配器...

public class CatGridAdapter extends BaseAdapter {


private List<Model> catList;


public CatGridAdapter(List<Model> catList) {
    this.catList = catList;
}
@Override
public int getCount() {
    return catList.size();
}

@Override
public Object getItem(int position) {
    return null;
}

@Override
public long getItemId(int position) {
    return 0;
}

@Override
public View getView(int position, View convertView, ViewGroup parent) {
    View view;

    if (convertView == null) {
        view = LayoutInflater.from(parent.getContext()).inflate(R.layout.quizitem, parent, false);
    } else {
        view = convertView;
    }
    ((TextView) view.findViewById(R.id.title)).setText(catList.get(position));
    ((TextView) view.findViewById(R.id.subTitle)).setText(catList.get(position));


    return view;
}
}

這是 model class ...

    private String cat;
    private String SubTitle;

    public Model(String cat, String subTitle) {
        this.cat = cat;
        SubTitle = subTitle;
    }

    public String getCat() {
        return cat;
    }

    public void setCat(String cat) {
        this.cat = cat;
    }

    public String getSubTitle() {
        return SubTitle;
    }

    public void setSubTitle(String subTitle) {
        SubTitle = subTitle;
    }
}

MainActivity class ...

     catGrid = findViewById(R.id.catGridView);


        List<Model> catList = new ArrayList<>();
        catList.add(new Model("Cat1","subTitle1"));
        catList.add(new Model("Cat2","subTitle2"));
        catList.add(new Model("Cat3","subTitle3"));
        catList.add(new Model("Cat4","subTitle4"));
        catList.add(new Model("Cat5","subTitle5"));
        catList.add(new Model("Cat6","subTitle6"));


        CatGridAdapter adapter = new CatGridAdapter(catList);
        catGrid.setAdapter(adapter);
    }

將您的代碼更改為：

((TextView) view.findViewById(R.id.title)).setText(catList.get(position).getCat());
((TextView) view.findViewById(R.id.subTitle)).setText(catList.get(position).getSubTitle());
