Question

这就是我尴尬的DB看起来像atm。我想尝试根据年龄对嵌套的哈希进行排序。我已经环顾四周了，所有我能找到的是如何在哈希中对哈希进行排序，但是当嵌套的哈希值在数组内时则不行。我确定有一些简单的方法来改变结构或按照它的方式对其进行排序。

{ :room1 => [{
  :fred => { :name => "Fred", :age => 23 },
  :joan => { :name => "Joan", :age => 18 },
  :pete => { :name => "Pete", :age => 54 }
}],
:room2 => [{
  :jan => { :name => "jan", :age => 2 },
  :eric => { :name => "eric", :age => 3 },
  :stan => { :name => "stan", :age => 1 }
}]}

提前致谢！顺便说一句，这是我在这里的第一个问题。要温柔^^。

试试这个

     @Override
        public View getView(final int position, View convertView, ViewGroup parent) {
            // TODO Auto-generated method stub
            Holder holder=new Holder();
            View rowView;

            rowView = inflater.inflate(R.layout.item_category_list, null);
            holder.tv=(TextView) rowView.findViewById(R.id.textView1);
// crasher here.
            holder.img=(ImageView) rowView.findViewById(R.id.imageView1);

            holder.tv.setText(result[position]);
            holder.img.setImageResource(imageId[position]);

            rowView.setOnClickListener(new OnClickListener() {

                @Override
                public void onClick(View v) {
                    // TODO Auto-generated method stub
                    Toast.makeText(context, "You Clicked "+result[position], Toast.LENGTH_LONG).show();
                }
            });

            return rowView;
            }

尝试在哈希
