getDrawable(int)在这行中是不推荐使用的警告:Drawable res=getContext()。getResources()。可提取(项目img_resId);

我已经创建了自己的自定义适配器。在这段代码中,我得到getDrawable(int)是不推荐的警告,在这一行: Drawable res = getContext().getResources().getDrawable(item.img_resId); .

Android getResources().getDrawable() deprecated API 22

Android: Alternative for context.getDrawable()

但在我的情况下,他们都没有工作。

我的代码:

public class CustomAdapter extends ArrayAdapter<ItemDataObject> {
private static class ViewHolder {
    ImageView img;
    TextView title;
    TextView sub_title;
}

public CustomAdapter(Context context, ArrayList<ItemDataObject> list_item_details) {
    super(context, 0, list_item_details);
}

@NonNull
@Override
public View getView(int position, View convertView, @NonNull ViewGroup parent) {
    // Get the data item for this position
    ItemDataObject item = getItem(position);
    // Check if an existing view is being reused, otherwise inflate the view
    ViewHolder viewHolder; // view lookup cache stored in tag
    if (convertView == null) {
        // If there's no view to re-use, inflate a brand new view for row
        viewHolder = new ViewHolder();
        LayoutInflater inflater = LayoutInflater.from(getContext());
        convertView = inflater.inflate(R.layout.listview_item, parent, false);
        viewHolder.img = convertView.findViewById(R.id.img);
        viewHolder.title = convertView.findViewById(R.id.tvTitle);
        viewHolder.sub_title = convertView.findViewById(R.id.tvSubTitle);
        // Cache the viewHolder object inside the fresh view
        convertView.setTag(viewHolder);
    } else {
        // View is being recycled, retrieve the viewHolder object from tag
        viewHolder = (ViewHolder) convertView.getTag();
    }
    // Populate the data from the data object via the viewHolder object into the template view.
    assert item != null;
    Drawable res = getContext().getResources().getDrawable(item.img_resId);
    viewHolder.img.setImageDrawable(res);
    viewHolder.title.setText(item.title);
    viewHolder.sub_title.setText(item.subtitle);
    // Return the completed view to render on screen
    return convertView;
    }
}
