Question

我想为自定义ArrayAdapter传递多个数组。这是我的数组和我想做的事情：

String[] names = new String[]{ "One", "two", "three" };

String[] texts = new String[]{ "Bacon", "Eggs", "Cheese" };

Customadapter ap = new Customadapter(this, names, texts);
setListAdapter(ap);

这是我的自定义ArrayAdapter：

public class Customadapter extends ArrayAdapter<String> {

    private final Activity context;
    private final String[] names;

    public Customadapter(Activity context, String[] names) {
        super(context, R.layout.row, names);
        this.context = context;
        this.names = names;
    }

    @Override
    public View getView(int position, View convertView, ViewGroup parent){
        LayoutInflater inflater = context.getLayoutInflater();
        View rowView = inflater.inflate(R.layout.row, null, true);
        TextView tw1 = (TextView) rowView.findViewById(R.id.label);
        TextView tw2 = (TextView) rowView.findViewById(R.id.label2);

        String text = names[position];
        tw2.setText(text);

        return rowView;

    }

}

Answer 1

您需要创建ArrayAdapter<Strings>

的适配器，而不是ArrayAdapter<HashMap<String,String>>

Answer 2

请尝试使用SimpleAdapter。

Answer 3

为启动器扩展BaseAdapter而不是ArrayAdapter，然后调整构造函数，使其获取文本字符串，以便将其存储在适配器中。这应该是主要的伎俩。有些方法需要覆盖afaik，但它在文档中有。
