I am creating a little social network application. I am trying to have a user post something, then be able to like statuses. Currently, if a user likes a status, twoproblems are occurring:
1: When a like button is pressed, it also likes the 'recycled view' button down the list and changes the text of the button on both to unlike, but not like count. ( If user likes the second post in the list, it will also change the text to unlike of other button down the list)
2: The button text will not stay as 'unlike' if the screen is changed.

Here is the custom adapter:

 public class PostsAdapter extends ArrayAdapter<Posts>  {
    //used to create views from xml
    Context context;
    int textViewResourceId;
    ArrayList<Posts> mPosts = new ArrayList<Posts>();

    public PostsAdapter(Context context, int textViewResourceId, ArrayList<Posts> posts) {
        super(context, textViewResourceId, posts);
        this.textViewResourceId = textViewResourceId;
        this.context = context;
        this.mPosts = posts;
    }

    // view convertview = recycled view
    @Override
    public View getView(final int position, View convertView, ViewGroup parent) {
        View view = convertView;
        final Holder holder;
        //checks if recycled view is null, thewn creates new view, if not null, use same view
        if(view == null){
            LayoutInflater inflater = ((Activity) context).getLayoutInflater();
            view = inflater.inflate(textViewResourceId, parent, false);

            Button like = (Button) view.findViewById(R.id.btnLike);
            TextView content = (TextView) view.findViewById(R.id.content);
            TextView user = (TextView) view.findViewById(R.id.user);
            TextView topic = (TextView) view.findViewById(R.id.topic);
            TextView date = (TextView) view.findViewById(R.id.date);
            TextView likes = (TextView) view.findViewById(R.id.likeCount);
            TextView hiddenId = (TextView) view.findViewById(R.id.hiddenID);
            holder = new Holder(content, user, topic, date, likes, hiddenId, like);

            holder.like.setOnClickListener(new View.OnClickListener() {
                @Override
                public void onClick(View v) {
                    createLike(position, holder.like, holder.hiddenId, holder.likes);//Added one more parameter "position"
                }
            });

            view.setTag(holder);
        }
        else{
            holder = (Holder) view.getTag();
        }

        Posts posts = mPosts.get(position);
        holder.content.setText(posts.getContent());
        holder.user.setText(posts.getUser());
        holder.topic.setText(posts.getTopic());
        holder.date.setText(posts.getDate());
        holder.likes.setText(posts.getLikes());
        holder.hiddenId.setText(posts.getId());

        return view;
    }

    private void createLike(final int position, final Button like, final TextView hiddenid, final TextView likes){
        final String hid = hiddenid.getText().toString().trim();

        if(like.getText().toString().equalsIgnoreCase("like")){
            System.out.println("MPOOSTSPOSITION: "+mPosts.get(position));
            mPosts.get(position);
            like.setText("UnLike");
            StringRequest stringRequest = new StringRequest(Request.Method.POST, Config.SERVER_ADDRESS + "LikePost.php",
                    new Response.Listener<String>() {

                            JSONObject jsonObject = null;
                            try {

I would really appreciate any help!
