android - 如何更新 OnItemSelected() 中的引用？

Question

是否可以在调用 notifyDataSetChanged 后更新 OnItemSelected 中的引用？例如

ImageView onFront;
gallery.setOnItemSelectedListener(new OnItemSelectedListener() {
            @Override
            public void onItemSelected(AdapterView<?> parent, View view,
                    int position, long id) {
                onFront = (ImageView) view;

            }

            @Override
            public void onNothingSelected(AdapterView<?> arg0) {
                // TODO Auto-generated method stub

            }
        });

我正在使用 onFront 旋转图像，但在我调用 notifyDataSetChanged 之后 - 我不能。

让您的代码记住点击了哪个 View 。

gallery.setOnItemSelectedListener(new OnItemSelectedListener() {
            @Override
            public void onItemSelected(AdapterView<?> parent, View view,
                    int position, long id) {
                view.setTag(postion);

            }

            @Override
            public void onNothingSelected(AdapterView<?> arg0) {
                // TODO Auto-generated method stub

            }
        });

然后在adapter的getview中使用这个位置

int pos = (Integer)view.getTag();
if(pos == position){
 //Make your change in view to make it look different
}
