这是我的适配器： 

@Override
    public View getView(int position, View convertView, ViewGroup parent) {
        //Put the food_list_layout in the convertView
        if(convertView == null){
            convertView = View.inflate(context, R.layout.preorder_list_layout_orders,null);
        }

这是我的XML文件：

您使用固定大小的视图，这使您的屏幕无响应。

如果你想实现一个响应式布局不要使用固定大小，你可以使用ConstraintLayout但使用android:layout_width="0dp" ， android:layout_width="wrap_content"属性和一些指南 。

这是您想要的布局的示例：
