我在自定义BaseAdapter中的getView方法中有这段代码：
public final View getView(int position, View convertView, ViewGroup parent) {
Log.e("blah","getView "+position);
View itemView = convertView;
ItemController renderer;
ItemType item = getItem(position);
if (itemView == null) {
renderer = createNewRenderer(item);
renderer._setItem(item);
itemView = renderer.createLayout(inflater);
renderer.init();
} else {
renderer = (ItemController) itemView.getTag();
if (renderer.getItem() != null && renderer.getItem() != item) {
renderer.dispose(); // Recycle images and other stuff
dispose(renderer); // I need to keep a mapping between the items in the gridview to the renderers, this will point older item to nothing.
}
// if (!reuseViews)
// itemView = renderer.createLayout(inflater);
renderer._setItem(item);
}
populateController(item, renderer);
renderer.renderImpl();
return itemView;
}
这是渲染3x3 GridView的输出：
getView #0

getView #1
getView #2
getView #3
getView #4

我在加载后动态渲染每个ItemRenderer的内容......
注意除第一项外，所有项目的表现都很好。
当我向下滚动时：

getView #10
