如果（id我找到了解决方案
我应该首先将循环视图实例从外部类传递到我的自定义适配器
薄内循环视图适配器，我可以得到它的位置在循环视图中的任何视图，并将其转换到视图持有人，然后可以做任何事情的持有人
以下是代码：
户外类：
mRecyclerView2 = (RecyclerView) findViewById(R.id.list_Fragment);
mRecyclerView2.setHasFixedSize(true);
mLayoutManager = new LinearLayoutManager(this);
mRecyclerView2.setLayoutManager(mLayoutManager);
mAdapter2 = new MyCustomAdapterPackages(this, PackagesList,mRecyclerView2);
mRecyclerView2.setAdapter(mAdapter2);
mAdapter2.notifyDataSetChanged();
在custome适配器类中：
@Override
public void onBindViewHolder(final MyCustomAdapterPackages.CustomViewHolderPackages holder, final int position) {
final Packages pa = packages.get(position);
holder.PackageButton.setText(pa.getPackageName());
holder.PackagePrice.setText(String.valueOf(pa.getPackagePrice()));
holder.PackageButton.setBackground(ContextCompat.getDrawable(mContext, R.drawable.tab_bg_selector));
holder.PackageButton.setId(position);
holder.PackageButton.setTag(id);
View.OnClickListener clickListener = new View.OnClickListener() {
@Override
public void onClick(View view) {
if(id<0){ // first time or default
view.setSelected(true);
id=view.getId();
}
else{
CustomViewHolderPackages row = (CustomViewHolderPackages)mRecyclerView.findViewHolderForAdapterPosition(id);
if( row.PackageButton.isSelected()) {
row.PackageButton.setSelected(false); // previous view
view.setSelected(true); // current view
id=view.getId();
}
else{
id=view.getId();
view.setSelected(true);
}
}
}
};
//Handle click event
holder.PackageButton.setOnClickListener(clickListener);

如果（id）您可以添加id字段吗？您在哪里设置clickListener到按钮？发布回收服务的完整代码我已经更新了帖子您可以添加id字段吗？您在哪里设置clickListener到按钮？发布回收服务的完整代码我已经更新了帖子
