ListView to RecyclerView conversion, problem in converting get View method

I want to convert Listview to RecyclerView in my app, I tried to convert code but stucked at getView method, can any one explain how to use this getView code in Recylcer view.
Adapter for ListView CardAdapter.java

The problem part..
public View getView(int position, View convertView, ViewGroup parent) {
ViewHolder holder = null;
if (convertView == null) {
LayoutInflater inflater = (LayoutInflater) context
.getSystemService(Activity.LAYOUT_INFLATER_SERVICE);
convertView = inflater.inflate(R.layout.card_list_item, null);
holder = new ViewHolder();
holder.CardNameTxt = (TextView) convertView
.findViewById(R.id.txt_crd_name);
holder.CardDescTxt = (TextView) convertView
.findViewById(R.id.txt_crd_desc);
holder.CardPriceTxt = (TextView) convertView
.findViewById(R.id.txt_crd_no);
holder.favoriteImg = (ImageView) convertView
.findViewById(R.id.imgbtn_favorite);
convertView.setTag(holder);
} else {
holder = (ViewHolder) convertView.getTag();
}
CardDataModel card = (CardDataModel) getItem(position);
holder.CardNameTxt.setText(card.getName());
holder.CardDescTxt.setText(card.getDescription());
holder.CardPriceTxt.setText(card.getPrice() + " ");
/*If a product exists in shared preferences then set heart_red drawable
* and set a tag*/
if (checkFavoriteItem(card)) {

holder.favoriteImg.setTag("red");
} else {
holder.favoriteImg.setImageResource(R.drawable.heart_grey);
holder.favoriteImg.setTag("grey");
}
return convertView;
}
How to modify this code and where to add this checkFavItem, add , and remove methods..suggest me , i am new to android development.

Ratingbar's rating within listview resets

Senario: To get rating feedback for multiple multiple products.
Problem: Ratingbar value resets on scrolling listview by calling setOnRatingBarChangeListener
Expected output:
Customized listview adpater code:
public class FeedbackAdapter extends BaseAdapter {
static Context context;
List<FeedbackRowDetails> row;
ViewHolder holder;
public FeedbackAdapter(Context context,List<FeedbackRowDetails> row)
{
this.context = context;
this.row =row;
}
private class ViewHolder {
TextView tv_slno, tv_productname, tv_time;
RatingBar rb_productrating;
}
#Override
public View getView( final int position, View convertView, ViewGroup parent) {
LayoutInflater mInflater = (LayoutInflater) context.getSystemService(Activity.LAYOUT_INFLATER_SERVICE);
if (convertView == null)
{
convertView = mInflater.inflate(R.layout.custom_feedback_row_format,null);
holder = new ViewHolder();
holder.tv_slno = (TextView) convertView.findViewById(R.id.tv_slno);
holder.tv_time = (TextView) convertView.findViewById(R.id.tv_time);
holder.tv_productname = (TextView) convertView.findViewById(R.id.tv_productname);
holder.rb_productrating=(RatingBar) convertView.findViewById(R.id.rb_productrating);
convertView.setTag(holder);
} else
{
holder = (ViewHolder) convertView.getTag();
}
FeedbackRowDetails row_pos = row.get(position);
holder.tv_slno.setText(String.valueOf(position + 1));
holder.tv_time.setText(row_pos.gettime());
holder.tv_productname.setText(row_pos.getproductsName());
holder.rb_productrating.setRating(Float.valueOf(row_pos.getrating()));
holder.rb_productrating.setOnRatingBarChangeListener(new OnRatingBarChangeListener()
{
public void onRatingChanged(RatingBar ratingBar, float rating,boolean fromUser)
{
FeedbackRowDetails row_pos = row.get(position);
int roundoff_rating = (int)Math.round(rating);
ratingBar.setRating(roundoff_rating);
row_pos.setrating(String.valueOf(roundoff_rating));
}
});
return convertView;
}
#Override
public int getCount() {
return row.size();
}
#Override
public Object getItem(int position) {
return row.get(position);
}
#Override
public long getItemId(int position) {
return row.indexOf(getItem(position));
}
}
Just wrap your codes present inside your onRatingChanged method with a simple if as shown below
if(fromUser) {
FeedbackRowDetails row_pos = row.get(position);
int roundoff_rating = (int) Math.round(rating);
ratingBar.setRating(roundoff_rating);
row_pos.setRating(String.valueOf(roundoff_rating));
}
Have tested it with emulator and it was working as expected. Hope this solves your problem

How can i make that positions go ++ and every of them be uniqe?

How ListView's recycling mechanism works
Change getView
public View getView( final int position, View convertView, ViewGroup parent)
{
ViewHolder holder;
if (convertView == null)
{
convertView = layoutInflater.inflate(R.layout.list_row_layout, null);
holder = new ViewHolder();
holder.headlineView = (TextView)convertView.findViewById(R.id.name);
holder.reportedDateView = (TextView) convertView.findViewById(R.id.confid);
holder.approve = (TextView) convertView.findViewById(R.id.approveTV);
convertView.setTag(holder);
}
else
{
holder = (ViewHolder) convertView.getTag();
}
FeedItem newsItem = (FeedItem) listData.get(position);
holder.approve.setFocusable(true);
holder.approve.setClickable(true);
holder.headlineView.setText(Html.fromHtml(newsItem.getTitle()));
holder.reportedDateView.setText(Html.fromHtml(newsItem.getContent()));
holder.approve.setTag(position);
holder.approve.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v)
{
Toast.makeText(mContext, String.valueOf(v.getTag()), Toast.LENGTH_LONG).show();
}
});
return convertView;
}
As you are reusing the view by
else{
holder = (ViewHolder) convertView.getTag();
}
so multiple textView using same listener. So Take your onclickListener outside of the if condition.
if (convertView == null)
{
convertView = layoutInflater.inflate(R.layout.list_row_layout, null);
holder = new ViewHolder();
holder.headlineView = (TextView)convertView.findViewById(R.id.name);
holder.reportedDateView = (TextView) convertView.findViewById(R.id.confid);
holder.approve = (TextView) convertView.findViewById(R.id.approveTV);
convertView.setTag(holder);
}
else
{
holder = (ViewHolder) convertView.getTag();
}
holder.approve.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v)
{
Toast.makeText(mContext, String.valueOf(position), Toast.LENGTH_LONG).show();
}
});
Add this code in your list adapter :
#Override
public int getViewTypeCount() {
// TODO Auto-generated method stub
return questionsClassArrayList_.size();
}
#Override
public int getItemViewType(int position) {
// TODO Auto-generated method stub
return position;
}

Optimize listview performance Android

I have a listView (vertical) and every list item has a horizontal list view (horizontal).
But the problem is when i scroll the horizontal scrollview in the row the vertical list is also calling getView()...
So, there is a huge performance hit..
So , can any one tell me a better solution to it ..
public class GridViewAdapter extends BaseAdapter {
List<List<Hotel>> gridDatasource;
Context mContext;
public GridViewAdapter(List<List<Hotel>> gridDatasource, Context context) {
this.gridDatasource = gridDatasource;
this.mContext = context;
}
public void setGridDatasource(List<List<Hotel>> gridDatasource) {
this.gridDatasource = gridDatasource;
}
#Override
public int getCount() {
if (gridDatasource == null) {
return 0;
}
return gridDatasource.size();
}
#Override
public Object getItem(int position) {
return gridDatasource.get(position);
}
#Override
public long getItemId(int position) {
return position;
}
#Override
public View getView(int position, View convertView, ViewGroup parent) {
GridViewHolder holder;
if (convertView == null) {
LayoutInflater inflater = (LayoutInflater) mContext

holder = new GridViewHolder();
holder.headerView = (TextView) convertView

convertView.setTag(holder);
} else {
holder = (GridViewHolder) convertView.getTag();
Log.d("TAG", "Reaching Here");
}
holder.headerView.setText("Hello From Sandeep");
HorizontalListViewAdapter adapter = new HorizontalListViewAdapter(
mContext, gridDatasource.get(position));
holder.listView.setAdapter(adapter);
return convertView;
}
}

return cell;
}
}
Dear i suggest to try My this Code
public View getView(final int position, View convertView, ViewGroup parent)
{
View v = convertView;
ViewHolder holder;
if (v == null)
{
v = inflater.inflate(R.layout.custom_image_layout, null);
holder = new ViewHolder();
holder.txtFileName = (TextView) v.findViewById(R.id.txtFileName);
holder.imageView = (ImageView) v.findViewById(R.id.imgView);
v.setTag(holder);
} else
{
holder = (ViewHolder) v.getTag();
}
holder.imageView.setImageBitmap(bm);
holder.txtFileName.setText(""+nameoffile);
return v;
}
static class ViewHolder
{
public ImageView imageView;
public TextView txtFileName;
}
Use The Holder Class
