I am not able to load more pages using Endless RecyclerView ScrollListener


I am not able to load more pages using Endless RecyclerView ScrollListener



I am using Recyclerview to achieve endless recyclerview scroll listener. Now it loading only page = 1 and page = 2 while scrolling but it not loading another pages, and I added EndlessRecyclerViewScrollListener class from github.



Activity


public class AccountPagination extends AppCompatActivity implements RestCallback {
String UserId, rollname, username, name, fname, lname, emailid, contact_no, gender1, date_of_birth, country_id, postal_code, profession_response, Street_Address, City;
NonScrollListView listItem;
public static AccountStatementAdapter adapter;
ArrayList<AccountStatementModel> AccountStatementList;
AccountsSortingAdapter adapterSort;
AccountsTenRecordsAdapter adapterTenRecords;
ArrayList<AccountStatementModel> AccountDetailsList;
ArrayList<AccountStatementModel> AccountSortingList;
ArrayList<AccountStatementModel> AccountTenRecordsList;

ArrayList<AccountStatementModel> androidVersions;
List<AccountStatementModel> AccountList;
RecyclerView recyclerView;
int userPage = 1;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_account_pagination);
initViews();

recyclerView = (RecyclerView) findViewById(R.id.card_recycler_view);
callAccountStatementAPI(userPage);
recyclerView.setHasFixedSize(true);
LinearLayoutManager linearLayoutManager = new LinearLayoutManager(getApplicationContext());
recyclerView.setLayoutManager(linearLayoutManager);
// recyclerView.setAdapter(adapter);
recyclerView.addOnScrollListener(new EndlessRecyclerViewScrollListener(linearLayoutManager) {
@Override
public void onLoadMore(int page, int totalItemsCount, RecyclerView view) {
userPage++;
callAccountStatementAPI(userPage);
}
});

//RecyclerView.LayoutManager layoutManager = new LinearLayoutManager(getApplicationContext());
//RecyclerView.LayoutManager layoutManager = new GridLayoutManager(getApplicationContext(), 1);


}

public void initViews() {
Intent i = getIntent();
UserId = i.getStringExtra("id");
name = SharedPref.read(SharedPref.FIRST_NAME, "") + "t" + SharedPref.read(SharedPref.LAST_NAME, "");
String Hello = "Hello " + name;
getSupportActionBar().setSubtitle(Hello);
}

private void callAccountStatementAPI(final int page) {

HashMap<String, String> map = new HashMap<String, String>();
map.put("user_id", SharedPref.read(SharedPref.USER_ID, ""));
map.put("page", String.valueOf(page));
RestService.getInstance(AccountPagination.this).getAccount1(map, new MyCallback<ArrayList<AccountStatementModel>>(AccountPagination.this,
AccountPagination.this, true, "Loading ...", GlobalVariables.SERVICE_MODE.ACCOUNT_STATEMENT));

}

@Override
public void onFailure(Call call, Throwable t, GlobalVariables.SERVICE_MODE mode) {

}

@Override
public void onSuccess(Response response, GlobalVariables.SERVICE_MODE mode) {
switch (mode) {
case ACCOUNT_STATEMENT:

androidVersions = (ArrayList<AccountStatementModel>) response.body();
AccountPaginationAdapter adapter = new AccountPaginationAdapter(getApplicationContext(), androidVersions);
androidVersions.addAll((Collection<? extends AccountStatementModel>) response.body());
adapter.notifyItemRangeInserted(adapter.getItemCount(), androidVersions.size()-2);
recyclerView.setAdapter(adapter);

break;
}
}
}



Adapter Class


public class AccountPaginationAdapter extends RecyclerView.Adapter<AccountPaginationAdapter.ViewHolder> {
private ArrayList<AccountStatementModel> android_versions;
private Context context;

private String TAG = "On Click";
String main_url = "http://www.consumer1st.in/ccb/";

public AccountPaginationAdapter(Context context, ArrayList<AccountStatementModel> android_versions) {
this.context = context;
this.android_versions = android_versions;

}

@Override
public AccountPaginationAdapter.ViewHolder onCreateViewHolder(ViewGroup viewGroup, int i) {
View view = LayoutInflater.from(viewGroup.getContext()).inflate(R.layout.accountpagination_item_list, viewGroup, false);
return new AccountPaginationAdapter.ViewHolder(view);
}

@Override
public void onBindViewHolder(AccountPaginationAdapter.ViewHolder viewHolder, final int position) {


viewHolder.lable_name.setText(android_versions.get(position).getRemarks());


viewHolder.icon_image.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {

String icoon_index_id = android_versions.get(position).getId();
String iconn_id = android_versions.get(position).getUserId();

}
});
}

@Override
public int getItemCount() {
return android_versions.size();
}

public class ViewHolder extends RecyclerView.ViewHolder {

TextView lable_name;

ImageView icon_image;

public ViewHolder(View view) {
super(view);

icon_image = (ImageView) itemView.findViewById(R.id.icon_image);
lable_name = (TextView) itemView.findViewById(R.id.lable_name);
}
}
}





That's not PHP.

Below the code will work But this code totally wrong way actually u are calling every api hit to creating new adapter and adding list. See more pagination examples and change it.. See reference here.



Write a method in Adapter Class:


public void addMoreItems(ArrayList<AccountStatementModel> newItems){
androidVersions.clear();
androidVersions.addAll(newItems);
}



Write Activity:


case ACCOUNT_STATEMENT:

androidVersions = (ArrayList<AccountStatementModel>) response.body();
AccountPaginationAdapter adapter = new AccountPaginationAdapter(getApplicationContext(), androidVersions);
androidVersions.addAll((Collection<? extends AccountStatementModel>) response.body());
adapter.addMoreItems(androidVersions);
adapter.notifyItemRangeInserted(adapter.getItemCount(), androidVersions.size()-2);
recyclerView.setAdapter(adapter);
break;
}





still its not working !!,

Try this you will get perfect result.

int pastVisiblesItems, visibleItemCount, totalItemCount;

recyclerView.addOnScrollListener(new
RecyclerView.OnScrollListener() {
@Override
public void onScrolled(RecyclerView recyclerView, int dx, int dy) {

if (dy > 0) {
visibleItemCount = layoutManager.getChildCount();
totalItemCount = layoutManager.getItemCount();
pastVisiblesItems = layoutManager.findFirstVisibleItemPosition();
if (loading && totalItemCount >= (pastVisiblesItems + 50)) {
userPage++;
callAccountStatementAPI(userPage);
Log.v("...", "Last Item Wow !");
//Do pagination.. i.e. fetch new data
}
}
}
});

Export result set on Dbeaver to CSV

Export result set on Dbeaver to CSV Normally I use Dbeaver for windows and always export my result set like this: run my query --> select the result --> export the result set --> select export to clipboard --> done This step by step puts my result set in my clipboard and I can paste it wherever I want to work with it. The problem is that now I am using dbeaver for mac and this guide is not working. I can go on until the moment that I select my result set like in the image below: exporting data set But once I go further in the process, in the last step I get: no query Note that in "source" it was suppose to show the query that originated the result set, but instead it says just "select. As a result it does't select my result or anything (besides being "successful"). Normally my query would show up there automatically and I couldn't find any option that corrects this problem in the menus. Please help me! Thanks. Aft...

Opening a url is failing in Swift breakpointing inside the callback and logging success shows false. I added itms-apps to my plist: LSApplicationQueriesSchemes and put this in my app delegate: func application(_ app: UIApplication, open url: URL, options: [UIApplicationOpenURLOptionsKey : Any] = [:]) -> Bool { return true } func moreTapped() { let url = NSURL(string: "itms-apps://itunes.com/developer/quantum-productions/id979315877") if #available(iOS 10.0, *) { UIApplication.shared.open(url! as URL, options: [:], completionHandler: {(success: Bool) in }) } else { UIApplication.shared.openURL(url! as URL) } } Are you testing on a real device? – rmaddy Jun 21 at 23:57 I try on a device, get "Cannot Connect to App Store".
