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>@Overridepublic 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。
