Question

我的数组适配器看起来像这样：

我也没有发布图片:(

我也希望忽略空洞的观点。我刚刚开始使用android，我试图操纵getview，但这不起作用。

任何人都可以帮助我。

这是我的代码

    public class MyCustomAdapter extends ArrayAdapter<String> {

    public MyCustomAdapter(Context context, int textViewResourceId,
            String[] objects) {
        super(context, textViewResourceId, objects);
        // TODO Auto-generated constructor stub
    }

    @Override
    public View getView(int position, View convertView, ViewGroup parent) {
        // TODO Auto-generated method stub
        // return super.getView(position, convertView, parent);

        View row = convertView;


        if (row == null) {
            LayoutInflater inflater = getLayoutInflater();
            row = inflater.inflate(R.layout.row, parent, false);

        }

        TextView label = (TextView) row.findViewById(R.id.rowText);
        label.setText(locatie[position]);
        ImageView icon = (ImageView) row.findViewById(R.id.icon);

        if (position == 0 && on1) {
            icon.setImageResource(R.drawable.bulpon);
        } else if (position == 1 && on2) {
            icon.setImageResource(R.drawable.bulpon);
        } else {
            icon.setImageResource(R.drawable.bulpoff);
        }

        return row;

    }
}




String[] locatie = { "Huiskamer - achter TV", "Huiskamer - kast",
        "Huiskamer - achter", "Keuken", "Voordeur", "", "", "", "",
        "", "" };

    haaldata();

在你的适配器中

你要创建这个方法

public class MyCustomAdapter extends BaseAdapter{
...
public int getCount() {
    return 5;//or however many you want to have total
}
...
}

在数组适配器中保留空视图
