我有一个网格视图。我有一个row.xml，我在Adapter类中充气。我的行xml有两个布局（一个是可见的，另一个是不可见的。）我正在做翻转动画。当我点击gridview的任何项目时，就会发生翻转动画，我正在看隐藏的布局，并隐藏那个可见的布局。 动画效果很好。但问题是，当我点击任何项目时，滚动其他项目也会翻转。所以当我意识到我没有得到具体的立场。 我尝试了以下代码。
@Override
public View getView(final int position, View convertView, ViewGroup parent) {
View row;
final RecordHolder holder = new RecordHolder();
animation1 = AnimationUtils.loadAnimation(context, R.anim.to_middle);
animation2 = AnimationUtils.loadAnimation(context, R.anim.from_middle);
if (convertView == null) {
row = View.inflate(context, R.layout.row_phone_and_tablet1, null);
} else {
//row = View.inflate(context, R.layout.row_phone_and_tablet1, null);
row = convertView;
}
holder.frontImage = (ImageView) row.findViewById(R.id.myimage_imgvw);
holder.frontMobileName = (TextView) row.findViewById(R.id.name_txtvw);
holder.frontPrice = (TextView) row.findViewById(R.id.price_txtvw);

此代码显示正确的位置，但在我滚动时下方，然后我仍然会翻转其他项目。请帮帮我。

要获得在GridView中单击的项目的确切位置，您需要在GridView参考上使用setOnItemClickListener，例如：
GridView g = (GridView) findViewById(R.id.gridView1);
g.setAdapter(new ImageAdopterShow(this)); // your custom adaptor object goes here
g.setOnItemClickListener(new OnItemClickListener() {
@Override
public void onItemClick(AdapterView<?> arg0, View arg1, int position,
long arg3) {
Toast.makeText(getBaseContext(), "position of item is " +position, Toast.LENGTH_SHORT).show();
}
});
这是我获取GridView中任何项目位置的方式。希望这能回答你的问题。
您的问题有点误导如果您可以获得项目位置，那么您需要更改您在GridView中无法正常工作的动画问题。
