RecyclerView displaying wrong data in other positions

RecyclerView displaying wrong data in other positions - android

I am creating a RecyclerView with Card view
my json data contains movie name,year,rating
my card view contains three text fields moviename,rating,year
when i click on rating field it should get the data from the json and display rating beside the rating text field, but the problem here is when i click on text field the data of my card view is displayed on other positions of the card view also.

}

#NonNull
#Override
public ViewHolder onCreateViewHolder(#NonNull ViewGroup parent, int viewType) {
View v = LayoutInflater.from(context).inflate(R.layout.single_item, parent, false);
final ViewHolder viewHolder = new ViewHolder(v);
viewHolder.view_container.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
// Intent i=new Intent(context,Main2Activity.class);
// String a=list.get(viewHolder.getAdapterPosition()).getTitle();
// Double b=list.get(viewHolder.getAdapterPosition()).getRating();
// int c=list.get(viewHolder.getAdapterPosition()).getYear();
// String g =String.valueOf(c);
// viewHolder.textYear.setText(g);
// i.putExtra("movie",a);
// i.putExtra("rating",b);
// i.putExtra("year",c);
// context.startActivity(i);
}
});
viewHolder.something.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
Double w = list.get(viewHolder.getAdapterPosition()).getRating();
String k = Double.toString(w);
viewHolder.textRating.setText(k);
}
});
return viewHolder;
}
#Override
public void onBindViewHolder(#NonNull final ViewHolder holder, int position) {
movie = list.get(position);
holder.textTitle.setText(movie.getTitle());
holder.view_container.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
int c = list.get(holder.getAdapterPosition()).getYear();
String g = String.valueOf(c);
holder.textYear.setText(g);
}
});
// holder.textRating.setText(String.valueOf(movie.getRating()));
// holder.textYear.setText(String.valueOf(movie.getYear()));
}
#Override
public int getItemCount() {
return list.size();
}
public class ViewHolder extends RecyclerView.ViewHolder {
TextView view_container;
TextView something;
public TextView textTitle, textRating, textYear;
public ViewHolder(#NonNull View itemView) {
super(itemView);
view_container = itemView.findViewById(R.id.textView5);
something = itemView.findViewById(R.id.Rating);
textTitle = itemView.findViewById(R.id.title);
textRating = itemView.findViewById(R.id.textView2);
textYear = itemView.findViewById(R.id.main_year);
}
}
}

Never bind data with view inside onCreateViewHolder method as you have done this on click of something' ,holder.textYear.setText(g);`
So instead of managing it like this, I suggest you to manage your rating textview with visibility.
Just move your click action inside onBindViewHolder(), and do below changes with it.
Double w = list.get(viewHolder.getAdapterPosition()).getRating();
String k = Double.toString(w);
viewHolder.textRating.setText(k);
viewHolder.textRating.setVisibility(View.INVISIBLE);
viewHolder.something.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
viewHolder.textRating.setVisibility(View.VISIBLE);
}
});
To maintain the review state:
First create one booelan variable inside your model class and generate getter-setter for that.
i.e.
private boolean isReviewedVisible = false;
public boolean isReviewedVisible() {
return isReviewedVisible;
}
public void setIsReviewedVisible(boolean isVisible) {
this.isReviewedVisible = isVisible;
}
Than add below checks in onBindViewHolder() method.
if(movie.isReviewedVisible()){
viewHolder.textRating.setVisibility(View.VISIBLE);
} else {
viewHolder.textRating.setVisibility(View.INVISIBLE);
}
viewHolder.something.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
movie.setReviewedVisible(true);
viewHolder.textRating.setVisibility(View.VISIBLE);
}
});

Don't forget to provide camera permission, as I don't check for it.

I have listview All the values are delete and update properly but only the last value is not delete in the listview.
Added a full fragment code. Take a look
For example
If I have three values in the listview If I delete 1 and 2 its removing and listview refresh properly but the last one is not refreshed in the listview

you have to tell your ListView that something changed in it's former List by calling notifyDataSetChanged() method of your adapter
Also you should not create a new instance of ArrayList, but only clear the old instance. Don't forget to check for null before clearing.

try calling the adapter again with a null like.
setListAdapter()

Problem
First item in the list maps to 5th item. 2nd item to sixth item. I mean if I change radio button at the first item, Same radio button gets selected at the 5th list item also.
Any suggestions?
Is it because of recycling?
How do I resolve it?
I tried saving in Question object and retrieving it. I used pos to retrieve and set. But same problem still exist.

I am saving the state of the person view inside of person object

how can i pass the image URL from activity to Alert Dialog box as a imageview?

Here is my CartRowHolder
class CartRowHolder {
ImageView icon;
TextView txtprice,txttitle,personalize;
TextView txtquantity;
ImageView imgdelete,imgedit,image;
public CartRowHolder(View v) {
icon=(ImageView)v.findViewById(R.id.imageicon);
txtprice=(TextView)v.findViewById(R.id.txtoprice);
txttitle=(TextView)v.findViewById(R.id.txtotitle);
txtquantity=(TextView)v.findViewById(R.id.txtoquantity);
personalize=(TextView)v.findViewById(R.id.txtpersonalize);
imgdelete=(ImageView)v.findViewById(R.id.imgdelete);
imgedit=(ImageView)v.findViewById(R.id.edit);

OK, you will need to following code:
1) add permission for internet in your manifest
<uses-permission android:name="android.permission.INTERNET" />
2) You will need to update your list adapter
private static final int MIN_RECORDS_NUMBER = 11;
private Context _con;
private List<Person> _data;
public PersonAdapter(Context context, List<Person> data)
{
_con = context;
_data = data;
}
#Override
public int getCount()
{
return _data.size();
}
#Override
public Person getItem(int position)
{
return _data.get(position);
}
#Override
public long getItemId(int position)
{
// TODO Auto-generated method stub
return 0;
}
#Override
public View getView(final int position, View convertView, ViewGroup parent)
{
Holder h = null;
if (convertView == null)
{
h = new Holder();
convertView = LayoutInflater.from(_con).inflate(R.layout.item_layout, parent, false);
h._backgroundItem = (LinearLayout) convertView.findViewById(R.id.item_layout);
h._fName = (TextView) convertView.findViewById(R.id.f_name);
h._lName = (TextView) convertView.findViewById(R.id.l_name);
h._age = (TextView) convertView.findViewById(R.id.age);
h._editBtn = (Button) convertView.findViewById(R.id.edit_btn);
convertView.setTag(h);
}
else
{
h = (Holder) convertView.getTag();
}
final Person p = getItem(position);
h._fName.setText(p._fName);
h._lName.setText(p._lName);
h._age.setText(String.valueOf(p._age));

public TextView _fName;
public TextView _lName;
public TextView _age;
public Button _editBtn;
}
public interface IDialog
{

3) update your mainactivity
public class MainActivity extends Activity implements IDialog

_listView.setOnItemClickListener(new OnItemClickListener()
{

}
}
});
}
private int getSelectedItemIndexByFName(String name)
{

}
return -1;

public Bitmap getBitmapFromURL(String src) {

HttpURLConnection httpCon = (HttpURLConnection) url.openConnection();
httpCon.setInstanceFollowRedirects(true);
Bitmap image = BitmapFactory.decodeStream(httpCon.getInputStream());
return image;

catch (MalformedURLException e)

#Override

dialog.setTitle("This is my custom dialog box");
dialog.setCancelable(true);
//there are a lot of settings, for dialog, check them all out!

}

}
4) custom image layout
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical" >
<ImageView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:id="#+id/image"/>
</LinearLayout>
A bit of explanation:
there is an interface between the activity and the list adapter (IDialog)
as part of the data, each item(person) has a field URL, when the user is clicking on the button, the activity is "notified" by the interface and downloading the appropriate image and showing it in the dialog

After so any hour I find out the Soloution. Now In the Dialog-box i can again download the image.....
imageFileURL="url";
String imageFileURL=cartItemList.get(position).getImage();
try {
URL url = new URL(imageFileURL);
URLConnection conn = url.openConnection();
HttpURLConnection httpConn = (HttpURLConnection)conn;
httpConn.connect();
InputStream inputStream = httpConn.getInputStream();
Bitmap bitmap = BitmapFactory.decodeStream(inputStream);
inputStream.close();
image.setImageBitmap(bitmap);
} catch (MalformedURLException e1) {
// TODO Auto-generated catch block
e1.printStackTrace();
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
