android - 如何从 getItemAtPostion 方法获取 View/Widget，android？

Question

如何使用 gallery.getItemAtPosition(position)获取如下所示的 View 对象。

Object obj = gallery.getItemAtPosition(position);
View v = (View)object;
ImageView imgview = (ImageView)v.findViewById(R.id.imageId);

但如果我那样使用它就会产生类转换异常。

通常我在选择事件时这样使用它

public void onItemSelected(AdapterView arg0, View v, int position,            long arg3) {        //here v is the imageview which is selected.                //In your case u might want something like this.                ImageView img = (ImageView) arg0.getChildAt(position); //To get the view}
