ListViewAdapter Class:

String url="http://bungie.net";

private Context context;
private GuardianInfo[] guardianList;
private LayoutInflater inflater;

public ListViewAdapter(Context context, int resource, GuardianInfo[] object) {
    super(context, resource, object);
    this.context = context;
    this.guardianList = object;
}

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

    if (inflater == null)
        inflater = (LayoutInflater) context
                .getSystemService(Context.LAYOUT_INFLATER_SERVICE);

    if (convertView == null)
        convertView = inflater.inflate(R.layout.listview_characters_content, parent, false);

    GuardianInfo guardian = guardianList[position];

    TextView textView_Class = (TextView) convertView.findViewById(R.id.listView_CLASS);
    textView_Class.setText(guardian.getCharacterBase().getClassType());

    ImageView imageView_IMG = (ImageView) convertView.findViewById(R.id.listView_IMG);
    ImageView imageView_BG = (ImageView) convertView.findViewById(R.id.listView_BG);

    Picasso.with(context).load(url + guardian.getEmblemPath()).into(imageView_IMG);
    Picasso.with(context).load(url + guardian.getBackgroundPath()).into(imageView_BG);

    return convertView;

}

现在，当我尝试更改 textView_Class 的文本时，似乎出现了错误。提示找不到资源

我还通过

设置了 ListAdapter

GuardianInfo[] guardians = response.body().getResponse().getData().getCharacters();

ListViewAdapter adapter = new ListViewAdapter(getBaseContext(), R.layout.listview_characters_content, guardians);

ListView listView_Characters = (ListView) findViewById(R.id.listView_Characters);
listView_Characters.setAdapter(adapter);

Answer 1

从异常来看，您似乎正在为 TextView 设置一些 int 值。当您为 TextView 设置一个 int 值时，它认为您正在尝试使用 ID 等于您的 int 值的 String 资源设置文本，在您的情况下可能是这个 guardian.getCharacterBase().getClassType()。尝试替换你的这条线

textView_Class.setText(guardian.getCharacterBase().getClassType());

有了这个

textView_Class.setText(String.valueOf(guardian.getCharacterBase().getClassType()));

Answer 2

显示您的列表项布局...R.layout.listview_characters_content
