我想为列表项创建一个类似的按钮，每当我点击like按钮，然后textview应该动态更新。但是当我点击按钮时，只有最后一行得到更新，其余的不会改变。请指导我完成这个在listitems中制作按钮的任务。（我已经使用了likebutton库来获得类似按钮）。
RecyclerViewAdapter.java
lScan = MapVirtualKey(eKeys, 1); //flag 1: returns virtual key code of scan code eKeys.
recycler_view_items.xml
public class RecyclerViewAdapter extends RecyclerView.Adapter<RecyclerViewAdapter.ViewHolder>{
private static final String TAG = "hh";
private String[] names;
private String[] desc;
private Integer[] imageid;
private Context context1;
ImageButton sare;
public ImageView img;
LikeButton likeButton;
TextView tx1;
TextView tx2;
TextView tx3;
TextView tx4;
public RecyclerViewAdapter(Context context2,String[] names,String[] desc,Integer[] imageid){
this.names = names;
this.desc = desc;
this.imageid = imageid;
context1 = context2;
}
public class ViewHolder extends RecyclerView.ViewHolder{
public LikeButton likeButton;
public ViewHolder(View v){
super(v);
}
}
@Override
public RecyclerViewAdapter.ViewHolder onCreateViewHolder(ViewGroup parent, int viewType){
View view1 = LayoutInflater.from(context1).inflate(R.layout.recycler_view_items,parent,false);
ViewHolder viewHolder1 = new ViewHolder(view1);
img = (ImageView) view1.findViewById(R.id.imgview1);
likeButton = (LikeButton) view1.findViewById(R.id.cvcv);
tx3 = (TextView)view1.findViewById(R.id.counttxt);
likeButton.setOnLikeListener(new OnLikeListener() {
@Override
public void liked(LikeButton likeButton) {
int count = Integer.parseInt(tx3.getText().toString());
Log.d("fgfgfgfgf", String.valueOf(count));
tx3.setText(String.valueOf(++count));
//tx3.setText(String.valueOf(Homefragment.countt));
}
@Override
public void unLiked(LikeButton likeButton) {
}
});
return viewHolder1;
}
@Override
public void onBindViewHolder(ViewHolder Vholder,final int position){
if(imageid[position] != null) {
// img.setImageBitmap(imageid[position]);
}
else{
}
img.setImageResource(imageid[position]);
tx1.setText(names[position]);
Vholder.itemView.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View view) {
}
});
}
@Override
public int getItemViewType(int position) {
return position;
}
@Override
public int getItemCount(){
return desc.length;
}
}

替换
tx3 = (TextView)view1.findViewById(R.id.counttxt);
带
TextView tx3 = (TextView)view1.findViewById(R.id.counttxt);
和
likeButton = (LikeButton) view1.findViewById(R.id.cvcv);
与
LikeButton likeButton = (LikeButton) view1.findViewById(R.id.cvcv);
在您的代码中，您使用instance tx3和likebutton .modalDialog {
position: fixed;
font-family: Arial, Helvetica, sans-serif;
top: 0;
right: 0;
bottom: 0;
left: 0;
background: rgba(0, 0, 0, 0.8);

}

display: none;
}
#showdiv1:target~div a[href="#hidediv1"],
#showdiv2:target~div a[href="#hidediv2"] {
display: inline-block;
}
#showdiv1:target~div .hiddendiv.nr1,
#showdiv2:target~div .hiddendiv.nr2 {
height: 150px;
}，并保存最后一个值，希望这会有所帮助

public class ViewHolder extends RecyclerView.ViewHolder{
LikeButton likeButton;
TextView tx1;
TextView tx2;
TextView tx3;
TextView tx4;
public ViewHolder(View v){
super(v);
img = (ImageView) v.findViewById(R.id.imgview1);
likeButton = (LikeButton) v.findViewById(R.id.cvcv);
tx3 = (TextView)v.findViewById(R.id.counttxt);
}
}
将您的OnCreateviewHolder更改为：-
@Override
public RecyclerViewAdapter.ViewHolder onCreateViewHolder(ViewGroup parent, int viewType){
View view1 = LayoutInflater.from(context1).inflate(R.layout.recycler_view_items,parent,false);
return new ViewHolder(view1);
}
OnBindViewHolder到：-
@Override
public void onBindViewHolder(ViewHolder Vholder,final int position){
Vholder.img.setImageResource(imageid[position]);
Vholder.tx1.setText(names[position]);
Vholder.itemView.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View view) {
}
});
Vholder.likeButton.setOnLikeListener(new OnLikeListener() {
@Override
public void liked(LikeButton likeButton) {
//Logic
}
@Override
public void unLiked(LikeButton likeButton) {
}
});
}
