I want to implement the load more functionality inside my Staggered gridview. I have tried some lines of code for it like using addOnScrollListener but did not call when i come to the bottom the list.
Please find my code which i have tried to implement the load more functionality but not getting the expected result.
MY_STRAGGED_RECYCLIVIEW.addOnScrollListener(new RecyclerView.OnScrollListener() { @Override public void onScrolled(RecyclerView recyclerView, int dx, int dy) { super.onScrolled(recyclerView, dx, dy); totalItemCount = staggeredGridLayoutManager.getItemCount(); lastVisibleItem = staggeredGridLayoutManager .findLastCompletelyVisibleItemPositions(null)[0]; if (!loading && totalItemCount <= (lastVisibleItem + visibleThreshold)) { // End has been reached // Do something System.out.println("I amm here dd "); loading = true; } } });In my above code, System.out is not getting print...
I have tried another listener for the stragged gridview that is setOnScrollChangeListener, but it is also not working
MY_STRAGGED_RECYCLIVIEW.setOnScrollChangeListener(new View.OnScrollChangeListener() { @Override public void onScrollChange(View v, int scrollX, int scrollY, int oldScrollX, int oldScrollY) { System.out.println("I amm here fffffffffff "); } });Same problem arises with this listener , not getting to print my System.out
On more thing which i have tried in my adapter class inside the onBindViewHolder method that is
if(getCount()==position){////for getting the last item of the recycleview}Above code is also not working..Please help me to short out from this problem..Thanks :)
@Abbas please check my adapter code below
public class StraggredView extends RecyclerView.Adapter<StraggredView.ViewHolder> { private List<Content> mDataSet; private Context ctx; public StraggredView(Context context, List<Content> arrList) { ctx = context; mDataSet = arrList; } @Override public StraggredView.ViewHolder onCreateViewHolder(ViewGroup parent, int viewType) { View view = LayoutInflater.from(parent.getContext()).inflate(R.layout.item_grid, parent, false); return new ViewHolder(view); } @Override public void onBindViewHolder(ViewHolder holder, final int position) { if(getItemCount()==position) { //// I AM NOT GETTING IT AT THE BOTTOM... IT INVOKED AS THE ADAPTER IS CALLED FIRST TIME...LOOK AT IT } if (mDataSet.get(position).getContentImage() == null || mDataSet.get(position).getContentImage().isEmpty()) { Glide.with(ctx).load(R.drawable.no_content) // .override(screenWidth / 2, Utils.dpToPx(height)) .into(holder.imgContent); } else { Glide.with(ctx).load(mDataSet.get(position).getContentImage()) // .override(screenWidth / 2, Utils.dpToPx(height)) // .centerCrop() //.transform(new CircleTransform()) .into(holder.imgContent); } holder.imgContent.setOnClickListener(new View.OnClickListener() { @Override public void onClick(View v) { if (mDataSet.get(position).getContentImage() != null || !mDataSet.get(position).getContentImage().isEmpty()) { FragmentActivity activity = (FragmentActivity) (ctx); FragmentManager fm = activity.getSupportFragmentManager(); FullScreenFragment dialog = FullScreenFragment.newInstance( mDataSet.get(position).getContentImage()); dialog.show(fm, "dialog"); } } }); } @Override public int getItemCount() { return this.mDataSet.size(); } public class ViewHolder extends RecyclerView.ViewHolder { public ImageView imgContent; public ViewHolder(View itemView) { super(itemView); imgContent = (ImageView) itemView.findViewById(R.id.imgContent); } }}
