Add progressbar to custom adapter and endless recyclerview

[meness]

Hi,

I'm using this library for the endless list but I don't know how to add the progressbar to the list. How can I add a progressbar?

[cymcsg]

You need to extend UltimateAdapter or you can achieve the feature in your adapter

[meness]

@cymcsg I'm extending that but I couldn't find how to add a progressbar. Can you please give me an example of adding a progressbar? thanks.

[meness]

@cymcsg Please help me with adding a progressbar to the recyclerview when the load more option is enabled.

[cymcsg]

In fact SimpleAdapter is an Adapter which extends UltimateAdapter.The loading more view has been defined as customLoadMoreView.

[meness]

I wrote following codes in my adapter which extends the UltimateViewAdapter but the ProgressBar not showing. Please give me a clear example.

@Override
    public View getCustomLoadMoreView() {
        super.getCustomLoadMoreView();
        View view = View.inflate(context, R.layout.progress_item, null);
        return view;
    }

And the ProgressBar layout content is

<?xml version="1.0" encoding="utf-8"?>
<ProgressBar
    android:id="@+id/progress_bar"
    style="@android:style/Widget.Holo.ProgressBar"
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_gravity="center_horizontal"
    android:indeterminate="true"/>

Have you read the source of this?

[meness]

I had read that! I really don't know why you don't give me an clear example! In than simple example, the ProgressBar has defined, but has no usage. So that progress bar will not be used by default. This is my idea. If I'm wrong, please guide me or the best idea is, write about adding progress bar in the documentation clearly. Thanks. I'm waiting for a good answer from you since 4 days ago! Please help me! Thanks.

[cymcsg]

Because I do not know about your code.Have you used enableloadmore method in your demo?

[meness]

I'm really thankful for your time. I give you my adapter and its usage. Please take a look at them and let me know how to add progress bar on load more.

UltimateRecyclerView recyclerView = (UltimateRecyclerView) rootView.findViewById(R.id.urv);
PersonTimelineAdapter mAdapter = new PersonTimelineAdapter(getActivity(), myItems);

recyclerView.setAdapter(mAdapter);
recyclerView.setHasFixedSize(true);
LinearLayoutManager layoutManager = new LinearLayoutManager(getActivity());
recyclerView.setLayoutManager(layoutManager);

recyclerView.enableLoadmore();
recyclerView.setOnLoadMoreListener(new UltimateRecyclerView.OnLoadMoreListener() {@Override
    public void loadMore(int itemsCount, final int maxLastVisiblePosition) {
        // load more data
    }
});

public class PersonTimelineAdapter extends UltimateViewAdapter < CellFeedViewHolder > {

    public PersonTimelineAdapter(Context context,
    List < CompactPostPerson > postList) {
        this.context = context;
        mPosts = postList;
    }

    @Override
    public CellFeedViewHolder getViewHolder(View view) {
        return new CellFeedViewHolder(view,
        false);
    }

        viewGroup,

        true);

        @Override

}

I have written a sample for just this.I think it'll help you.

Can you check this, UltimateViewAdapter.setCustomLoadMoreView() works with UltimateViewAdapter but not with MultiViewTypesRecyclerViewAdapter. When I scroll down, recycler view still loads more but there's not custom footer view.

[cymcsg]

@kientux MultiViewTypesRecyclerViewAdapter do not have full feature of UltimateViewAdapter in current version.It's need some time to improve it.
