android - Android 列表适配器中是否有值成员属性？

Question

android中的适配器是否可以显示成员和值成员？这意味着listView的值成员将被隐藏

Answer 1

您需要做的是构建一个Adapter包含对象列表的自定义。

目的

public class MyObject {
    private int id;
    private String name;
}

适配器

public class MyObjectListAdapter extends ArrayAdapter<MyObject> {
    private final Context  context;

    public MyObjectListAdapter(Context context, List<MyObject> objects) {
        super(context, R.layout.listview_myobjects, objects);
        this.context = context;
    }

    @Override
    public View getView(int position, View convertView, ViewGroup parent) {
        LayoutInflater inflater = (LayoutInflater) context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
        View rowView = inflater.inflate(R.layout.listview_myobject_item, parent, false);

        TextView textViewName = (TextView) rowView.findViewById(R.id.textViewObjectName);

        MyObject current = getItem(position);
        textViewName.setText(current.getName());
        return rowView;
    }
}
