我正在使用 Retrofit 下载产品列表 (JSON)，然后我会将收到的数据设置到我的回收站 View 中。
但是当我在回收站 View 上快速滚动时，当前 fragment (回收站 View 的容器)将关闭，我将转到主要 Activity 。我的 logCat 中没有错误。
这是我设置回收站 View 和改造的 fragment :
private RecyclerView singleListRecycler;
private RecyclerView.LayoutManager rtlGridLayoutManager;
private RecyclerView.Adapter weekAdapter;
private List<PList> singleList = new ArrayList<PList>();
private String prgCode;
private LinearLayout layoutLoading;
private TextView txtNoGood;
int totalPage = 1;
int currentPage = 1;
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
View view = inflater.inflate(R.layout.fragment_product, container, false);
inflater = (LayoutInflater) getActivity().getSystemService(Context.LAYOUT_INFLATER_SERVICE);
syncBasket();
user_auth = G.getPremiumState()[0];
user_pass = G.getPremiumState()[1];
user_mobile = G.getPremiumState()[2];
if (user_auth.equals("") || user_mobile.equals("") || user_pass.equals("")) {
Toast.makeText(getContext(), "خطایی رخ داده است ! مجدد تلاش کنید.", Toast.LENGTH_SHORT).show();
Intent goToStartup = new Intent(getContext(), ActivityStartup.class);
getActivity().finish();
startActivity(goToStartup);
}
singleListRecycler = (RecyclerView) view.findViewById(R.id.singleListRecycler);
layoutLoading = (LinearLayout) view.findViewById(R.id.layout_loading);
txtNoGood = (TextView) view.findViewById(R.id.txt_no_good);
Bundle bundle = getActivity().getIntent().getExtras();
if (bundle != null) {
prgCode = bundle.getString("PRG_CODE");
} else {
Intent goBack = new Intent(getContext(), ActivityMainProducts.class);
startActivity(goBack);
}
//Preparing data from server for this group
getSingleGroup(prgCode, currentPage);
//Add Two Listener to RecyclerView
singleListRecycler.addOnScrollListener(new PicassoOnScrollListener(context));
singleListRecycler.addOnScrollListener(new RecyclerView.OnScrollListener() {
@Override
public void onScrolled(RecyclerView recyclerView, int dx, int dy) {
super.onScrolled(recyclerView, dx, dy);
if (dy < 0) {
// Recycle view scrolling up ...
// Toast.makeText(activitySingleGroup, "Top", Toast.LENGTH_SHORT).show();
} else if (dy > 0) {
if (!singleListRecycler.canScrollVertically(View.SCROLL_AXIS_VERTICAL)) {
currentPage = currentPage + 1;
if (currentPage > totalPage) {
currentPage = totalPage;
layoutLoading.setVisibility(View.GONE);
} else {
layoutLoading.setVisibility(View.VISIBLE);
getSingleGroup(prgCode, currentPage);
}
}
}
}
});
return view;
}
private void getSingleGroup(String code, int page) {
if (singleList.size() == 0) {
G.showProgress(getActivity());
}
APIService apiService = ServiceGenerator.createService(APIService.class, user_auth, user_pass);
String url = "prg/" + code + "/" + page;
Call<ProductModel> call = apiService.getNormalList(url);
call.enqueue(new Callback<ProductModel>() {
@Override
public void onResponse(Call<ProductModel> call, Response<ProductModel> response) {
layoutLoading.setVisibility(View.GONE);
Log.i("LOGO", "Code of Normal is: " + response.code());
if (singleList.size() == 0) {
G.dismissProgress();
}
if (response.code() == 200) {
ProductModel newMainCategory = response.body();
totalPage = newMainCategory.getPTotalPage();
singleList.addAll(newMainCategory.getPList());
rtlGridLayoutManager = new RtlGridLayoutManager(getContext(), 1);
singleListRecycler.setLayoutManager(rtlGridLayoutManager);
weekAdapter = new BaseListAdapter(singleList, (ActivitySingleGroup) getActivity());
if (singleList.size() > 0) {
singleListRecycler.setAdapter(weekAdapter);
} else {
singleListRecycler.setVisibility(View.GONE);
txtNoGood.setVisibility(View.VISIBLE);
}
} else {
singleListRecycler.setVisibility(View.GONE);
txtNoGood.setVisibility(View.VISIBLE);
}
}
@Override
public void onFailure(Call<ProductModel> call, Throwable t) {
Log.i("LOGO", "Error s: " + t.toString());
if (singleList.size() == 0) {
G.dismissProgress();
}
layoutLoading.setVisibility(View.GONE);
singleListRecycler.setVisibility(View.GONE);
txtNoGood.setVisibility(View.VISIBLE);
}
});
}
这是recyclerView的适配器:
public class BaseListAdapter extends RecyclerView.Adapter<BaseListAdapter.ViewHolder> {
private List<PList> menuItems;
private Context mContext;
private ActivitySingleGroup activitySingleGroup;
private int lastPosition = -1;
public BaseListAdapter(List<PList> menuItems, Context mContext) {
this.menuItems = menuItems;
this.mContext = mContext;
this.activitySingleGroup = (ActivitySingleGroup) mContext;
}
public static class ViewHolder extends RecyclerView.ViewHolder {
TextView txtName;
TextView txtPrice;
ImageView imgDefault;
LinearLayout parentLayout;
CoordinatorLayout coordinatorLayout;
public ViewHolder(View v) {
super(v);
txtName = (TextView) v.findViewById(R.id.txtName);
txtPrice = (TextView) v.findViewById(R.id.txtPrice);
imgDefault = (ImageView) v.findViewById(R.id.img_defaultImage);
parentLayout = (LinearLayout) v.findViewById(R.id.parentLayout);
coordinatorLayout = (CoordinatorLayout) v.findViewById(R.id.coordinatorLayout);
}
}
@Override
public BaseListAdapter.ViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
// Create a new View
final View v = LayoutInflater.from(activitySingleGroup).inflate(R.layout.activity_normal_group_recycler, parent, false);
ViewHolder vh = new ViewHolder(v);
return vh;
}
@Override
public void onBindViewHolder(final ViewHolder holder, final int position) {
//Download and Load Default Image from server into imgDefault ImageView
Picasso picasso;
OkHttpClient client = null;
String url = "https://bartarinapp-irdeveloper.rhcloud.com/api/images/download/";
//Handel situations that default image variables will be null
if (menuItems.get(position).getPDefaultImage() != null &&
menuItems.get(position).getPDefaultImage().getDefault() != null) {
if ((menuItems.get(position).getPDefaultImage().getDefault()) &&
(menuItems.get(position).getPDefaultImage().getIId() != null)) {
url += menuItems.get(position).getPDefaultImage().getIId();
client = ServerClass.setAuthImage();
picasso = new Picasso.Builder(mContext)
.downloader(new OkHttp3Downloader(client))
.listener(new Picasso.Listener() {
@Override
public void onImageLoadFailed(Picasso picasso, Uri uri, Exception exception) {
//Here your log
Log.i("I_ERROR", "Error is: " + exception.toString());
}
})
.build();
} else {
url = null;
picasso = new Picasso.Builder(mContext)
.listener(new Picasso.Listener() {
@Override
public void onImageLoadFailed(Picasso picasso, Uri uri, Exception exception) {
//Here your log
Log.i("I_ERROR", "Error is: " + exception.toString());
}
})
.build();
}
} else {

.listener(new Picasso.Listener() {
@Override
public void onImageLoadFailed(Picasso picasso, Uri uri, Exception exception) {

Log.i("I_ERROR", "Error is: " + exception.toString());
}
})
.build();
}
picasso.cancelRequest(holder.imgDefault);
if (url != null && url.length() > 0) {
//put here picaso image load code
picasso.load(url)
.tag(PicassoOnScrollListener.TAG)
.placeholder(R.drawable.loading_01)
.error(R.drawable.loading_02)
.into(holder.imgDefault);
} else {
holder.imgDefault.setImageResource(R.drawable.ic_empty_white_box);
}
holder.txtName.setText(menuItems.get(position).getPName());
holder.txtPrice.setText(String.valueOf(menuItems.get(position).getPPrice()));
holder.parentLayout.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View view) {
prepareBottomSheet(view, position, holder.coordinatorLayout);
}
});
}
@Override
public int getItemCount() {
if (menuItems.size() > 0) {
return menuItems.size();
} else {
return 0;
}
}
我在回收站 View 中使用了 Picasso。我不知道这里发生了什么! 当应用程序将关闭当前 fragment 或有时会崩溃时，这是我的 logCat。

感谢您的回答。
最佳答案
看起来您正在使用不同的库版本。
请提供您的 build.gradle 文件。
