I have created a row inside recycler view and inside that I have inflated two rows or more but when I scroll the items are getting used again. I am not getting where to recycle view or remove them dynamically I need a feed and their comments.For comments I need to inflate layouts to display them below feeds for which getCommentInflaterView method is created.
But the view created using getCommentInflaterView() gets duplicated. MyAdapterClass:
public class AllFeedsAdapter extends
RecyclerView.Adapter<AllFeedsAdapter.ViewHolder> {
ArrayList<Data> arrayListAllFeedsData;
Comment objComment;
Context context;
public AllFeedsAdapter(Context context, ArrayList<Data> data) {
this.context = context;
arrayListAllFeedsData = new ArrayList<>();
arrayListAllFeedsData = data;
}
@Override
public AllFeedsAdapter.ViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
Context context = parent.getContext();
LayoutInflater inflater = LayoutInflater.from(context);
// Inflate the custom layout
View post_row_view = inflater.inflate(R.layout.row_teacher_post, parent, false);
// Return a new holder instance
ViewHolder viewHolder = new ViewHolder(post_row_view);
return viewHolder;
}
@Override
public void onBindViewHolder(AllFeedsAdapter.ViewHolder holder, int position) {
holder.txtUsernamePostCreator.setText(arrayListAllFeedsData.get(position).getFull_name());
holder.txtPostContent.setText(arrayListAllFeedsData.get(position).getFeed_text());
holder.txtPostLikeCounter.setText(arrayListAllFeedsData.get(position).getTotal_like());
holder.txtPostCommentsCounter.setText(arrayListAllFeedsData.get(position).getTotal_comment());
if (arrayListAllFeedsData.get(position).getComment().size() > 0) {
if (arrayListAllFeedsData.get(position).getComment().size() > 2) {
for (int i = 0; i < 2; i++) {
objComment = arrayListAllFeedsData.get(position).getComment().get(i);
if (getCommentInflaterView(objComment) == null) {
holder.llCommentRowInflater.addView(getCommentInflaterView(objComment));
} else {
holder.llCommentRowInflater.removeAllViews();
}
}
} else {
for (int i = 0; i < arrayListAllFeedsData.get(position).getComment().size(); i++) {
objComment = arrayListAllFeedsData.get(position).getComment().get(i);
if (getCommentInflaterView(objComment) == null) {
holder.llCommentRowInflater.addView(getCommentInflaterView(objComment));
} else {
holder.llCommentRowInflater.removeAllViews();
}
}
}
}
}
private View getCommentInflaterView(Comment commentData) {
LayoutInflater layoutInflater = LayoutInflater.from(context);
View v = layoutInflater.inflate(R.layout.post_comments_list_item, null, false);
TextView txtCommenterUsername = (TextView) v.findViewById(R.id.txt_username_commenter);
TextView txtCommenterComment = (TextView) v.findViewById(R.id.txt_comments_from_commenter);
TextView txtCommentDuration = (TextView) v.findViewById(R.id.txt_comment_duration);
txtCommenterUsername.setText(commentData.getUsername());
txtCommenterComment.setText(commentData.getComment());
txtCommentDuration.setText(commentData.getCommentBy());
return v;
}
@Override
public int getItemCount() {
return arrayListAllFeedsData.size();
}
/**
* USed to create static class for all the view if listitem child
*/
public static class ViewHolder extends RecyclerView.ViewHolder {
// Your holder should contain a member variable
// for any view that will be set as you render a row
public LinearLayout llParentTeacherPost, llCommentRowInflater;
// We also create a constructor that accepts the entire item row
// and does the view lookups to find each subview
public ViewHolder(View itemView) {
// Stores the itemView in a public final member variable that can be used
// to access the context from any ViewHolder instance.
super(itemView);
llParentTeacherPost = (LinearLayout) itemView.findViewById(R.id.ll_parent_teacher_post);
llCommentRowInflater = (LinearLayout) itemView.findViewById(R.id.ll_comment_row_inflater);
imgDpPostCreator = (ImageView) itemView.findViewById(R.id.img_dp_post_creator);
txtUsernamePostCreator = (TextView)
}
}
}
Override these two methodes in adapter.
@Override
public long getItemId(int position) {
return position;
}
@Override
public int getItemViewType(int position) {
return position;
}
