我有一个listview，其中包含一个自定义适配器，可以扩展布局。适配器膨胀的布局包含多个按钮。我的目标是为自定义适配器中的每个项目扩展此布局，并使与该布局对应的按钮仅响应它所在的布局（它所在的列表视图项目位置）。这是我的自定义适配器的代码：
private class StableArrayAdapter extends ArrayAdapter<String> {
public FragmentManager fragmentManager;
ViewHolder viewHolder;
private final Context context;
private List<String> viewContent;
//private List<String> posts;
private List<String> posts;
int index = 0;
String title;
TextView testText;
public StableArrayAdapter(Context context, List<String> strings, List<String> content) {
super(context, R.layout.post_layout, strings);
this.context = context;
this.posts = strings;
this.viewContent = content;
}
@Override
public View getView(final int position, View postLayout, final ViewGroup parent) {
viewHolder = new ViewHolder();
positionHolder = position;
Log.i("Position", "" + position);
if(postLayout == null) {
Log.i("CONVERTVIEW", "Convert View is null");
LayoutInflater inflater = (LayoutInflater) context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
postLayout = inflater.inflate(R.layout.post_layout, parent, false);
viewHolder.addToCalVF = (ViewFlipper)postLayout.findViewById(R.id.addToCalendarVF);

根据我的理解，使用自定义适配器，屏幕上可见项目的位置被视为位置0，位于位置1之后的位置。我通过使用3个项目填充列表视图来测试3个布局被扩展到列表视图中。但是，当我单击布局上的任何按钮时，会发生正确的操作，但是对于距离所需布局1个项目的布局也会发生这种情况。因此，当我单击位置0列表视图中布局中的按钮时，位于列表视图中位置2的布局会发生相同的操作，反之亦然，当我在列表视图位置2中选择一个按钮时，我会尝试制作每个按钮。 listview项目针对每个特定位置独立且正确地运行，但我无法自己或在互联网上找到答案。如何在自定义适配器中正确添加onclicklistener，使视图的行为适合其所需位置？就像按钮这样的Instagrams如何“喜欢”想要的图片一样？
