How to update imageview from the parent recyclerview after click on nested recyclerview's imageview

Please check following screenshot, I want to update imageview from parent recyclerview when user click on imageview from nested recyclerview.
I have taken two individual adapters for for parent & nested recyclerview.I am not able to do the functionality for updating image, kindly help.
Parent Recyclerview Adapter:
public class RecyclerViewDataAdapter extends RecyclerView.Adapter<RecyclerViewDataAdapter.ItemRowHolder> {
private ArrayList<PLDModel> dataList;
private Context mContext;
public RecyclerViewDataAdapter(Context context, ArrayList<PLDModel> dataList) {
this.dataList = dataList;
this.mContext = context;
}
#Override
public ItemRowHolder onCreateViewHolder(ViewGroup viewGroup, int i) {
View v = LayoutInflater.from(viewGroup.getContext()).inflate(R.layout.item_card_view, null);
ItemRowHolder mh = new ItemRowHolder(v);
return mh;
}
#Override
public void onBindViewHolder(ItemRowHolder itemRowHolder, int i) {
final String itemTitle = dataList.get(i).getTitle();
final String itemDescription = dataList.get(i).getDescription();
ArrayList<SmallImages> singleSectionItems = dataList.get(i).getSmallImages();
itemRowHolder.itemTitle.setText(Html.fromHtml("<b>" + itemTitle + " </b> " + itemDescription));
SectionListDataAdapter itemListDataAdapter = new SectionListDataAdapter(mContext, singleSectionItems);
itemRowHolder.recyclerSmallImageList.setHasFixedSize(true);
itemRowHolder.recyclerSmallImageList.setLayoutManager(new LinearLayoutManager(mContext, LinearLayoutManager.HORIZONTAL, false));
itemRowHolder.recyclerSmallImageList.setAdapter(itemListDataAdapter);
}
#Override
public int getItemCount() {
return (null != dataList ? dataList.size() : 0);
}
public class ItemRowHolder extends RecyclerView.ViewHolder {
protected TextView itemTitle, expandImage;
protected ImageView bookmarkImage,largeImage;
protected RecyclerView recyclerSmallImageList;
protected Button btnMore;
public ItemRowHolder(View view) {
super(view);
this.itemTitle = (TextView) view.findViewById(R.id.title);
this.bookmarkImage = (ImageView) view.findViewById(R.id.bookmark);
this.largeImage = (ImageView) view.findViewById(R.id.large_image);
this.expandImage = (TextView) view.findViewById(R.id.expand);
this.recyclerSmallImageList = (RecyclerView) view.findViewById(R.id.recycler_small_image_list);
}
}
}
Nested Recyclerview Adapter:
public class SectionListDataAdapter extends RecyclerView.Adapter<SectionListDataAdapter.SingleItemRowHolder> {
private ArrayList<SmallImages> itemsList;
private Context mContext;
public SectionListDataAdapter(Context context, ArrayList<SmallImages> itemsList) {
this.itemsList = itemsList;
this.mContext = context;
}
#Override
public SingleItemRowHolder onCreateViewHolder(ViewGroup viewGroup, int i) {
View v = LayoutInflater.from(viewGroup.getContext()).inflate(R.layout.small_images_view, null);
SingleItemRowHolder mh = new SingleItemRowHolder(v);
return mh;
}
#Override
public void onBindViewHolder(SingleItemRowHolder holder, int i) {
SmallImages singleItem = itemsList.get(i);
}
#Override
public int getItemCount() {
return (null != itemsList ? itemsList.size() : 0);
}
public class SingleItemRowHolder extends RecyclerView.ViewHolder {
protected ImageView itemImage;
public SingleItemRowHolder(View view) {
super(view);
//this.tvTitle = (TextView) view.findViewById(R.id.tvTitle);
this.itemImage = (ImageView) view.findViewById(R.id.item_small_image);
view.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
//Toast.makeText(v.getContext(), tvTitle.getText(), Toast.LENGTH_SHORT).show();
}
});
}
}
}

Using two Recyclerview will be hard to control rather than use a Single adapter and control everything from there.I have just worked on this type of thing that's why I am posting my code there may be some unwanted code which u may need.

Generally, the solution is to pass custom interface listener into the nested adapter and than the nested adapter will report any time one of his item clicked.
1.
You can create interface like:
public interface INestedClicked {
onNestedItemClicked(Drawable drawble)
}
2.
Pass in the constructor of SectionListDataAdapter a INestedClicked:
SectionListDataAdapter itemListDataAdapter = newSectionListDataAdapter(mContext, singleSectionItems, new INestedClicked() {
#Override
void onNestedItemClicked(Drawable drawble) {
// Do whatever you need after the click, you get the drawable here
}
});
In the constructor of SectionListDataAdapter save the instance of the listener as adapter parameter
private INestedClicked listener;
4.
When nested item clicked report the listener:
view.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
if(listener != null){
listener.onNestedItemClicked(imageView.getDrawable());
}
}

I want to get selected radio button position or value and id so that on button click I tried with but it always take first position. Can any one suggest me where am I doing wrong? I have to get selected radio button position so that I can get value from list of Objects. I have to send into next activity.

In adapter create a method which returns the object of selected position. Like :
public ListofAddressesDataModel getSelectedItem() {
return data.get(selectedPosition);
}
In activity, on click of the button call this method. Like :
#Override
public void onClick(View v) {
if(v.getId() == R.id.button) {
//Here you will get the selected item of which the radio button is checked
ListofAddressesDataModel selectedItem = ((ListofAddressesAdapter) add.getAdapter()).getSelectedItem();
}
}
EDIT :
Instead of below lines in getView() in adapter
holder.r.setTag(position);
holder.r.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
selectedPosition = (Integer) view.getTag();
name = data.get(selectedPosition).getName();
phone = data.get(selectedPosition).getPhone();
address = data.get(selectedPosition).getFulladdress();
customeraddressid = data.get(selectedPosition).getCustaddid();
notifyDataSetChanged();
}
});
just replace it with below line
holder.r.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
selectedPosition = position;
}
});

Custom Listview onClick not moving to Tab Fragments page

I have an activity with CustomAdapter ListView and TabLayout with three tabs TrainerTab1, TrainerTab2, TrainerTab3. While clicking on an item it should move to next page that is to TrainerTab1 Fragment.
I need to pass the id from ListView onClick() to fragment page. I have used Bundle to pass value but the items are not working. When I click on an item it's not responding and not showing any error.
My custom ListView Class is:
public class Trainer extends AppCompatActivity {
String tabUrl = "http://adoxsolutions.in/numuww/services/trainers";
private GridView gridView;
ArrayList<HashMap<String, String>> alist = new ArrayList<>();
private TrainAdapter adapter;

StrictMode.setThreadPolicy(policy);
getSupportActionBar().setDisplayHomeAsUpEnabled(true);
getSupportActionBar().setDisplayShowHomeEnabled(true);
new Train().execute();
}
private class Train extends AsyncTask<Void, Void, Void> {

mprogress = new ProgressDialog(Trainer.this);
mprogress.setMessage("Loading...");
mprogress.setIndeterminate(false);
mprogress.show();
}

InputStream in = new BufferedInputStream(connect.getInputStream());
String response = org.apache.commons.io.IOUtils.toString(in, "UTF-8");

Inside the onClickListener
after adding the bundle to the fragment.
FragmentManager fragmentManager = Trainer.this.getSupportFragmentManager();
FragmentTransaction transaction = fragmentManager.beginTransaction();
transaction.add(R.id.someIDForYourFrameLayout, tt1).commit();

can you just ellaborate where to use this exactly. I mean I don't understand how to add id of fragment to transaction.add(R.id.someIDForYourFrameLayout, tt1).commit();
I tried like this:
Bundle h=new Bundle();
h.putString("id",MyArr.get(position).get("id"));
Fragment tt1=new TrainerTab1();
tt1.setArguments(h);
FragmentTransaction transact=getSupportFragmentManager().beginTransaction();
transact.add(R.id.trainerFragment,tt1).commit();

Circular imageview dissappears in listview after fling

Im generating a feed full of images (similar to instagram post) using Glide for loading images and user's profile picture. After i get the data from server, i load the Url's of images inside the listitem. Initally All items are being loaded properly.
The issue is that when i fast scroll the listview, user profile picture dissappears and that view doesnt respond to onClick Events. Please explain why this happens and how can i resolve this?

When loading multiple images there is always caching problem when using Async Tasks. I recommend an open source library Picasso. It will load the images and cache it. After that most probably, your fast scroll problem will solve.
The cause can also be the size of the images being received. Picasso has methods by which you can resize the image before putting it onto the image view

Having an issue with a custom listview adapter

As the title states, I'm having some troubles getting my custom listView adapter to work. The app doesn't crash, but it also displays nothing on the list. I tested my data with a simple list I already have setup, and that worked just fine.
History.java
public class History {
public String score;
public String gametype;
public int icon;
public History() {
super();
}
public History(String score, String gametype, int icon) {
super();
this.score = score;
this.gametype = gametype;
this.icon = icon;
}
}
HistoryAdapter.java
public class HistoryAdapter extends ArrayAdapter<History> {
Context context;
int layoutResId;
History data[] = null;
public HistoryAdapter(Context context, int layoutResId, History[] data) {
super(context, layoutResId, data);
this.layoutResId = layoutResId;
this.context = context;
this.data = data;
}
#Override
public View getView(int position, View convertView, ViewGroup parent) {
HistoryHolder holder = null;
if(convertView == null)
{
LayoutInflater inflater = ((Activity)context).getLayoutInflater();
convertView = inflater.inflate(layoutResId, parent, false);
holder = new HistoryHolder();
holder.imageIcon = (ImageView)convertView.findViewById(R.id.icon);
holder.textTitle = (TextView)convertView.findViewById(R.id.gameType);
holder.textScore = (TextView)convertView.findViewById(R.id.score);
convertView.setTag(holder);
}
else
{
holder = (HistoryHolder)convertView.getTag();
}
History history = data[position];
holder.textScore.setText(history.score);
holder.textTitle.setText(history.gametype);
holder.imageIcon.setImageResource(history.icon);
return convertView;
}
static class HistoryHolder
{
ImageView imageIcon;
TextView textTitle;
TextView textScore;
}
}

You are creating a History object with this line:
new History(score[i], champId[i], R.drawable.ic_launcher); // Placeholder image
This just calls the constructor and creates an object for the garbage collector to take away again.
You are not actually adding this History object to the historyData array.
Before the loop, you should declare the historyData array as:
History[] historyData = new History[games.length();
And in the loop, you should assign the created object to the array
historyData[i] = new History(score[i], champId[i], R.drawable.ic_launcher); // Placeholder image
