使用Recycler视图加载更多调用Api

标签： java android android-recyclerview

你好我有从api获取数据的Recycler视图，并且所有请求都给了我10个项目，知道我需要为这个回收器实现更多负载并且每个滚动得到另外10个项目，我尝试了很多次但是它没有工作，请帮助这是我的代码

适配器 

   private int previousTotal = 0;
    private boolean loading = true;
    private int visibleThreshold = 0;
    int firstVisibleItem, visibleItemCount, totalItemCount;

 final LinearLayoutManager mLayoutManager = (LinearLayoutManager) mRecyclerView
                .getLayoutManager();

        mRecyclerView.addOnScrollListener(new RecyclerView.OnScrollListener() {

            @Override
            public void onScrolled(RecyclerView recyclerView, int dx, int dy) {
                super.onScrolled(recyclerView, dx, dy);

                visibleItemCount = mRecyclerView.getChildCount();
                totalItemCount = mLayoutManager.getItemCount();
                firstVisibleItem = mLayoutManager.findFirstVisibleItemPosition();

                if (loading) {
                    if (totalItemCount > previousTotal) {
                        loading = false;
                        previousTotal = totalItemCount;
                    }
                }
                if (!loading && (totalItemCount - visibleItemCount)
                        <= (firstVisibleItem + visibleThreshold)) {
                    fragment.getHtmlNewsData("1");
                    loading = true;
                }
            }
        });

此处为活动 

     public void getHtmlNewsData(final String pageNumber) {
        BusinessManager.getNewsDataMethod(pageNumber, new ApiCallResponse() {
            @Override
            public void onSuccess(String StringResponse) {
                String Response = (String) StringResponse;
                try {
                    html = Response.toString();
                    String[] MainSperatedList = html.toString().split("<div class=\"views-field views-field-field-date\">");

                    final List<String> stringsDate = new ArrayList<String>();
                    for (int counter = 1; counter < MainSperatedList.length; counter++) {
                        String Text = MainSperatedList[counter].toString();
                        String ItemSelected = Jsoup.parse(Text).select("span.date-display-single").text();
                        stringsDate.add(ItemSelected);
                        Log.d("AAAAAAA", ItemSelected);
                    }

 mLayoutManager = new LinearLayoutManager(context);
                    recyclerViewNews.setLayoutManager(mLayoutManager);
                    newsReycelerViewAdapter = new NewsReycelerViewAdapter(recyclerViewNews, context, stringsDate, stringsTitle, stringsDetails, stringsImages, new JPANewsFragment());
                    recyclerViewNews.setAdapter(newsReycelerViewAdapter);
                    if (!pageNumber.equals("0"))
                    newsReycelerViewAdapter.notifyDataSetChanged();
}
}

此代码对我不起作用，如果有人有想法请告诉我

我已经通过使用这两个工具来实现这一点并调用了recyclelerview方法addOnScrollListener。

首先在java包中创建这两个util：

<强> EndlessRecyclerOnScrollListener.java 

package your.pakage.name;
import android.support.v7.widget.LinearLayoutManager;
import android.support.v7.widget.RecyclerView;

public abstract class EndlessRecyclerOnScrollListener extends RecyclerView.OnScrollListener {
public static String TAG = EndlessRecyclerOnScrollListener.class.getSimpleName();

private int previousTotal = 0; // The total number of items in the dataset after the last load
private boolean loading = true; // True if we are still waiting for the last set of data to load.
private int visibleThreshold = 5; // The minimum amount of items to have below your current scroll position before loading more.
int firstVisibleItem, visibleItemCount, totalItemCount;

private int current_page = 1;

private LinearLayoutManager mLinearLayoutManager;

public EndlessRecyclerOnScrollListener(LinearLayoutManager linearLayoutManager) {
    this.mLinearLayoutManager = linearLayoutManager;
}

@Override
public void onScrolled(RecyclerView recyclerView, int dx, int dy) {
    super.onScrolled(recyclerView, dx, dy);

    visibleItemCount = recyclerView.getChildCount();
    totalItemCount = mLinearLayoutManager.getItemCount();
    firstVisibleItem = mLinearLayoutManager.findFirstVisibleItemPosition();

    if (loading) {
        if (totalItemCount > previousTotal) {
            loading = false;
            previousTotal = totalItemCount;
        }
    }
    if (!loading && (totalItemCount - visibleItemCount)
            <= (firstVisibleItem + visibleThreshold)) {
        // End has been reached

        // Do something
        current_page++;

        onLoadMore(current_page);

        loading = true;
    }
}

   public abstract void onLoadMore(int current_page);
 }

<强> HidingScrollListener.java 

package you.package.name;

import android.support.v7.widget.LinearLayoutManager;
import android.support.v7.widget.RecyclerView;


public abstract class HidingScrollListener extends RecyclerView.OnScrollListener {

private static final int HIDE_THRESHOLD = 20;

private int mScrolledDistance = 0;
private boolean mControlsVisible = true;


@Override
public void onScrolled(RecyclerView recyclerView, int dx, int dy) {
    super.onScrolled(recyclerView, dx, dy);

    int firstVisibleItem = ((LinearLayoutManager) recyclerView.getLayoutManager()).findFirstVisibleItemPosition();

    if (firstVisibleItem == 0) {
        if(!mControlsVisible) {
            onShow();
            mControlsVisible = true;
        }
    } else {
        if (mScrolledDistance > HIDE_THRESHOLD && mControlsVisible) {
            onHide();
            mControlsVisible = false;
            mScrolledDistance = 0;
        } else if (mScrolledDistance < -HIDE_THRESHOLD && !mControlsVisible) {
            onShow();
            mControlsVisible = true;
            mScrolledDistance = 0;
        }
    }
    if((mControlsVisible && dy>0) || (!mControlsVisible && dy<0)) {
        mScrolledDistance += dy;
    }
}

public abstract void onHide();
public abstract void onShow();
}

现在添加这两个之后创建你的activity.java就像这样：

<强> MyActivity.java 

package your.package.name;

}

private void hideViews() {

}
private void showViews() {
   // cardView.animate().translationY(0).setInterpolator(new DecelerateInterpolator(2));
}
}

并非适配器的变化，但我要添加它：

<强> MyAdapter.java 

package your.package.name;



public class ProductAdapter extends 
RecyclerView.Adapter<ProductAdapter.MyViewHolder> {
    private ArrayList<ProductModel> list;
    private ArrayList<ProductModel> filterList;
    Context mContext;
    private static final int MAX_WIDTH = 400;
private static final int MAX_HEIGHT = 400;
int size = (int) Math.ceil(Math.sqrt(MAX_WIDTH * MAX_HEIGHT));
private String rupeeSymbol = "\u20B9";
public ProductAdapter(Context mContext, ArrayList<ProductModel> list) {
    this.list = list;
    this.filterList=list;
    this.mContext = mContext;
}

@Override
public ProductAdapter.MyViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
    View itemView = LayoutInflater.from(parent.getContext()).inflate(R.layout.cardview_products, parent, false);
    return new ProductAdapter.MyViewHolder(itemView);
}

@Override
public void onBindViewHolder(final ProductAdapter.MyViewHolder holder, int position) {
    Typeface montserratregular = Typeface.createFromAsset(mContext.getAssets(), "font/montserratregular.ttf");
    final ProductModel productModel = filterList.get(position);
    //setting width & height
  /*  DisplayMetrics displayMetrics = new DisplayMetrics();
    ((Activity) mContext).getWindowManager().getDefaultDisplay().getMetrics(displayMetrics);
    int height = displayMetrics.heightPixels / 4;
    int width = (int) (displayMetrics.widthPixels * 0.9);
    holder.itemView.setLayoutParams(new LinearLayout.LayoutParams(width, height));*/
    holder.product_name.setText(productModel.getProduct_title());
    Picasso.with(mContext)
            .load(productModel.getProduct_imageFront())
            .transform(new BitmapTransForms(MAX_WIDTH, MAX_HEIGHT))
            .into(holder.product_image);
    holder.tv_actualPrice.setText(rupeeSymbol+productModel.getExpected_payout());
    holder.tv_previousPrice.setText(rupeeSymbol+productModel.getMrp());
    holder.tv_previousPrice.setPaintFlags(holder.tv_previousPrice.getPaintFlags() | Paint.STRIKE_THRU_TEXT_FLAG);
   // holder.tv_percentOff.setText(productModel.getMargin());

    // Toast.makeText(mContext,productModel.getProduct_title(),Toast.LENGTH_LONG).show();
    holder.tv_actualPrice.setTypeface(montserratregular);
    holder.tv_previousPrice.setTypeface(montserratregular);
    holder.tv_percentOff.setTypeface(montserratregular);
    holder.tv_ratingNumber.setTypeface(montserratregular);
    holder.product_name.setTypeface(montserratregular);
    holder.tv_rating.setTypeface(montserratregular);
}

@Override
public int getItemCount() {

    return filterList.size();

}

class MyViewHolder extends RecyclerView.ViewHolder implements View.OnClickListener {
    TextView product_name,tv_actualPrice,tv_previousPrice,tv_percentOff,tv_ratingNumber,tv_rating;
    ImageView product_image;
    MyViewHolder(View itemView) {
        super(itemView);
        product_name = (TextView) itemView.findViewById(R.id.tv_productname);
        product_image = (ImageView) itemView.findViewById(R.id.iv_products);
        tv_actualPrice = (TextView) itemView.findViewById(R.id.tv_actualPrice);
        tv_previousPrice = (TextView) itemView.findViewById(R.id.tv_previousPrice);
        tv_ratingNumber = (TextView) itemView.findViewById(R.id.tv_ratingNumber);
        tv_rating = (TextView) itemView.findViewById(R.id.tv_rating);
        tv_percentOff = (TextView) itemView.findViewById(R.id.tv_percentOff);
        itemView.setOnClickListener(this);
    }

    @Override
    public void onClick(View v) {
        final ProductModel productModel = filterList.get(getAdapterPosition());
        Intent i = new Intent(mContext, SingleProductView.class);
        i.putExtra("image",productModel.getProduct_imageFront());
        i.putExtra("name",productModel.getProduct_title());
        i.putExtra("actualprice",productModel.getExpected_payout());
        i.putExtra("previousPrice",productModel.getMrp());
        i.putExtra("productId",productModel.getApi_product_id());
        Toast.makeText(mContext,productModel.getApi_product_id(),Toast.LENGTH_LONG).show();
        mContext.startActivity(i);
    }
}
}

它肯定会在Youractivity.java页面编号上尝试它，如果您的第一页获得十，那么在滚动后它将增加并获得第二页值，现在您的回收器上有20个项目。如果有任何问题，请告诉我评论，我会让他们离开。

答案 1 :(得分：0)

从 RecyclerView.java

使用 addOnScrollListener（OnScrollListener侦听器） 
/**
 * Add a listener that will be notified of any changes in scroll state or position.
 *
 * <p>Components that add a listener should take care to remove it when finished.
 * Other components that take ownership of a view may call {@link #clearOnScrollListeners()}
 * to remove all attached listeners.</p>
 *
 * @param listener listener to set or null to clear
 */
public void addOnScrollListener(OnScrollListener listener)

实现：

recyclerView.addOnScrollListener(new RecyclerView.OnScrollListener() {
        @Override
        public void onScrolled(RecyclerView recyclerView, int dx, int dy) {
            if (dy > 0 && loadingData) {
                visibleItemCount = layoutManager.getChildCount();
                totalItemCount = layoutManager.getItemCount();
                pastVisiblesItems = layoutManager.findFirstVisibleItemPosition();
                if ((visibleItemCount + pastVisiblesItems) >= totalItemCount) {
                    //loading flag set to false once data received for the scroll
                    loadingData = false;
                    //Network call using pagination information when scrolled
                    get(pagination, networkRequest);
                }
            }
        }
    });
    clearData();
    //Initial network call to get data from network
    get(pagination, networkRequest);
