ArrayAdapter＆LT; D​​ummyContent.DummyItem＆GT;与android.R.layout.simple_list_item_activated_2 [英] ArrayAdapter<DummyContent.DummyItem> with android.R.layout.simple_list_item_activated_2

问题描述

我目前使用在我的Andr​​oid应用程序项目的主/详细流程。现在，我想不仅创建项目的列表只有一个字符串。我想标准的DummyItem类更改为以下内容：

I'm currently using the master / detail flow in my android application project. Now I would like to not only create a list with items with only one string. I'd like to change the standard DummyItem class to the following:

     /**
     * A dummy item representing a piece of content.
     */
    public static class DummyItem {
        public String id;
        public String content;
        public String subtext; //Added subtext variable here
        public DummyItem(String id, String content, String subtext) {
            this.id = id;
            this.content = content;
            this.subtext = subtext; //And here
        }

        @Override
        public String toString() {
            return content;
        }
    }

在ItemListFragment类我在这行code $ P $为列表创建适配器对定义的：

In the ItemListFragment class I'm having this line of code pre-defined for creating the adapter for the list:

    setListAdapter(new ArrayAdapter<DummyContent.DummyItem>(getActivity(), 
                   android.R.layout.simple_list_item_activated_1, 
                   android.R.id.text1, 
                   DummyContent.ITEMS));

但我想更改 android.R.layout.simple_list_item_activated_1 到 android.R.layout.simple_list_item_activated_2

虽然具有 android.R.id.text1 的内容和 android.R.id.text2 我的潜台词 -variable。

while having android.R.id.text1 as content and android.R.id.text2 as my subtext-variable.

有没有可能做到这一点？

Is there a possibility to do this?

推荐答案

重写getView一个ArrayAdapter（）方法。应该是这样的：

Overwrite the getView() Method of the ArrayAdapter. Should be something like this:

@Override
public View getView(int position, View convertView, ViewGroup parent) {

    //super call to create / recycle the view
    View view = super.getView(position, convertView, parent);

    TextView textView1 = (TextView) view.findViewById(android.R.id.text1);
    textView1.setText(getItem(position).getContent());

    TextView textView2 = (TextView) view.findViewById(android.R.id.text2);
    textView2.setText(getItem(position).getSubtext());

    return view;

}
