Answer 1

public siliderAdapter(Food cat, String[] data, int[] icons) {

    text = data;
    imgIcon = icons;
    context = cat;
    inflater = (LayoutInflater)context.
            getSystemService(Context.LAYOUT_INFLATER_SERVICE);
}

这一行

context = cat;

您将食物变量（cat）分配给上下文（上下文）类型的变量，这是一个错误。

修改构造函数并将Context作为参数传递。

public siliderAdapter(Context ctx, Food cat, String[] data, int[] icons) {

    text = data;
    imgIcon = icons;
    context = ctx;
    inflater = (LayoutInflater)context.
            getSystemService(Context.LAYOUT_INFLATER_SERVICE);
}
