android控件——继承AdapterView的控件无法使用addView方法

今天在写安卓的时候，使用ViewPager，每一个页面都使用到ListView，但是突然又不想写Adapter，然后就想自己添加几个TextView进去测试测试。

谁知道，调用了AddView方法后报错了。

添加的代码如下：

<span style="white-space:pre">	</span>@Override
public Object instantiateItem(View view, int position) // 实例化Item
{
Toast.makeText(mContext, "ListView"+position, 1000).show();
((ViewPager) view).addView(mViewList.get(position), 0);
ListView listView = mViewList.get(position);

TextView txt = new TextView(mContext);
txt.setText("ViewPager "+ (position+1)+" ");
txt.setTextSize(20);
txt.setGravity(Gravity.CENTER);
listView.addView(txt, 0);
return listView;
}

报的错误如下：

大概的意思就是，继承了AdapterView的控件是不支持AddView（）方法的。所以说，还是要自己写Adapter类才行，实在是太苦逼了！

于是乎我就继续写Adapter了。
