我有一个listview，我想显示像zodiac Sign Image这样的自定义数据。十二生肖。十二生肖内容和几个按钮。问题是数据没有显示我调试每一行，项目正确地添加到arraylist然后进入适配器但是listview在屏幕上显示为空。

我正在使用android google api17 jelly beans version

2 个答案:

答案 0 :(得分：2)

在您的ZodicAdapter类中 getCount（）您将返回0。

将其作为

@Override
public int getCount() {
    // TODO Auto-generated method stub
    return items.size();
}

答案 1 :(得分：0)

您正在0中返回getCount()，因此该列表认为适配器中没有任何项目。
