我正在为 android 开发一个应用程序,并希望使用 GridView 构建一个带有图标的菜单。为此,我使用了http://www.edumobile.org/android/android-beginner-tutorials/draw-menu-in-grid-view/的现有解决方案,但结果系统显示mThumbIds -无法解决对于一个变量,当我尝试将其声明为新的局部变量时,错误仍然存​​在。我是android新手,可能犯了非常简单的错误,但我自己无法解决。因此,任何建议都会有所帮助。这是代码:

    public class ImageAdapter extends BaseAdapter {
    public ImageAdapter(Context c) {
        mContext = c;
    }
    public int getCount() {
        return mThumbIds.length;
    }
    public Object getItem(int position) {
        return position;
    }
    public long getItemId(int position) {
        return position;
    }

    public View getView(int position, View convertView, ViewGroup parent) {
        ImageView imageView;

        if (convertView == null) {
            imageView = new ImageView(mContext);
            imageView.setLayoutParams(new GridView.LayoutParams(45, 45));
            imageView.setAdjustViewBounds(false);
            imageView.setScaleType(ImageView.ScaleType.CENTER_CROP);
            imageView.setPadding(8, 8, 8, 8);
        } else {
            imageView = (ImageView) convertView;
        }

        imageView.setImageResource(mThumbIds[position]);
        return imageView;
    }

    private Context mContext;
    private Integer[] mThumIbs = {
            R.drawable.ic_cards, R.drawable.ic_bank,
            R.drawable.ic_currency, R.drawable.ic_calc,
            R.drawable.ic_banking, R.drawable.ic_call,
    };

}

你有一个错字:

private Integer[] mThumIbs = {
            R.drawable.ic_cards, R.drawable.ic_bank,
            R.drawable.ic_currency, R.drawable.ic_calc,
            R.drawable.ic_banking, R.drawable.ic_call,
    };

而不是mThumbIbs,这不应该是mThumbIds吗?
