您必须实现你自己的适配器和 getView（）方法来设置 OnClickListener 你的按钮。在这里揭开序幕例如：

 公共类CustomAdapter扩展ArrayAdapter＆LT;整数GT; {
    私人的ListView ListView的;    公共CustomAdapter（上下文的背景下，INT textViewResourceId，整数[]对象，ListView控件的ListView）{
        超（背景下，textViewResourceId，对象）;
        this.listView = ListView的;
    }
    静态类ViewHolder {
        TextView的文本;
        按钮BTN;
    }    @覆盖
    公共查看getView（最终诠释的立场，观点convertView，父母的ViewGroup）{
        整色=的getItem（位置）;        查看rowView = convertView;        如果（rowView == NULL）{
            LayoutInflater充气=（（活动）的getContext（））getLayoutInflater（）;
            rowView = inflater.inflate（R.layout.list_view_row，父母，假）;
            ViewHolder H =新ViewHolder（）;
            h.text =（TextView中）rowView.findViewById（R.id.item_text）;
            h.btn = rowView.findViewById（R.id.btn）;
            rowView.setTag（H）;
        }        ViewHolder H =（ViewHolder）rowView.getTag（）;        h.text.setText（颜色）;
        h.indicator.setOnClickListener（新View.OnClickListener（）{
            @覆盖
            公共无效的onClick（视图v）{
                //你想在BTN点击收到那里。
            }
        }）;        返回rowView;
    }
}
 

ViewHolder这里进行优化。你可以阅读有关此有的。

I have defined a custom view (xml) for my ArrayAdapter for a ListView, which adds a Button. I'd like to create an OnClickListener for this Button per row, but without creating a custom adapter. Is that possible, or does Android force me to create a custom ArrayAdapter for my ListView?

Here's a snippet of what I'm doing:

glAdapter = new ArrayAdapter<Group>(getActivity(), R.layout.fragment_grouprow, R.id.groupRowText, ListOfGroups);
ListView groupListView = (ListView)mainView.findViewById(R.id.listViewGroupMain);
groupListView.setAdapter(glAdapter);
groupListView.setOnItemClickListener(new AdapterView.OnItemClickListener() {
    @Override
      public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
          // Call function
      }
});

Now I'd like to add an OnClickListener for the Button in my custom view.

You have to implement you own Adapter and in getView() method set OnClickListener on your button. Here kick off example:

public class CustomAdapter extends ArrayAdapter<Integer> {
    private ListView listView;

    public CustomAdapter(Context context, int textViewResourceId, Integer[] objects, ListView listView) {
        super(context, textViewResourceId, objects);
        this.listView = listView;
    }


    static class ViewHolder {
        TextView text;
        Button btn;
    }

    @Override
    public View getView(final int position, View convertView, ViewGroup parent) {
        Integer color = getItem(position);

        View rowView = convertView;

        if (rowView == null) {
            LayoutInflater inflater = ((Activity) getContext()).getLayoutInflater();
            rowView = inflater.inflate(R.layout.list_view_row, parent, false);
            ViewHolder h = new ViewHolder();
            h.text = (TextView) rowView.findViewById(R.id.item_text);
            h.btn = rowView.findViewById(R.id.btn);
            rowView.setTag(h);
        }

        ViewHolder h = (ViewHolder) rowView.getTag();

        h.text.setText(color);
        h.indicator.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                // DO what you want to recieve on btn click there.
            }
        });

        return rowView;
    }
}

ViewHolder here for optimization. You can read about this there.
