我点击它的任何项目只是改变recyclerview textview中最后一项的颜色而且图像也在改变最后添加的项目 但我希望该项目的图像和文字颜色应该改变我点击
这是我的适配器类 公共类MyAdapter扩展了RecyclerView.Adapter {
private static final int TYPE_HEADER = 0; // Declaring Variable to Understand which View is being worked on
// IF the view under inflation and population is header or Item

mRecyclerView.addOnItemTouchListener(new RecyclerView.OnItemTouchListener() {
@Override

if(child!=null && mGestureDetector.onTouchEvent(motionEvent)){

我已经搜索了很多并在stackoverflow上进行了搜索，但是没有任何工作。请帮助我，因为一些事情而被困在我身上。

尝试将根视图添加到viewHolder并将onclick侦听器附加到它。
public class ViewHolder extends RecyclerView.ViewHolder {
public View root;
public ViewHolder ( View itemView ) {
super ( itemView );
this.root = itemView;
}
}
在onBindViewHolder中设置onClickListener，如此
holder.root.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
holder.imageView.setImageResource("whatever image");
holder.textView.setTextColor(Color.parseColor("#000000"));
}
});

尝试将根视图添加到ViewHolder，如下所示：

使用xml id从视图中获取Imageview，因为您没有将标记设置为ViewHolder
ImageView img = (ImageView )child.findViewById(R.id.youXmlName);
