Recyclerview only displaying the first five items in a cursor

I'm trying to populate a recyclerview with a loader but the adapter will only bind the first five items on the database and then repeat for every other item in the database.
To make it clear, it looks like this:
item 1
item 2
item 3
item 4
item 5
item 1
item 2
...
The number of items still matches the number of items on the database though. I've also tested the cursor and it prints every item correctly so I'm assuming the problem is the adapter. This is what I'm using:
class LibraryAdapter extends RecyclerView.Adapter<LibraryAdapter.LibraryViewHolder> {
private Context mContext;
private Cursor mCursor;
LibraryAdapter(Context context, Cursor cursor){
this.mContext = context;
this.mCursor = cursor;
setHasStableIds(true);
}
static class LibraryViewHolder extends RecyclerView.ViewHolder implements View.OnClickListener {
private TextView titleText;
private TextView numText;
LibraryViewHolder(View itemView) {
super(itemView);
titleText = (TextView) itemView.findViewById(R.id.titleText);
numText = (TextView) itemView.findViewById(R.id.numText);
itemView.setOnClickListener(this);
}
#Override
public void onClick(View v) {
....
}
}
#Override
public LibraryAdapter.LibraryViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
View view = LayoutInflater.from(parent.getContext()).inflate(R.layout.list_item, parent, false);
return new LibraryViewHolder(view);
}
#Override
public void onBindViewHolder(LibraryAdapter.LibraryViewHolder holder, int position) {
LibraryModel item = getData(position);
holder.titleText.setText(item.getTitle());
holder.numText.setText(item.getNum() + " items");
}
#Override
public int getItemCount() {
return (mCursor != null) ? mCursor.getCount() : 0;
}
private Cursor swapCursor(Cursor cursor){
if(mCursor == cursor){
return null;
}
Cursor oldCursor = mCursor;
this.mCursor = cursor;
if(cursor != null){
this.notifyDataSetChanged();
}
return oldCursor;
}
void changeCursor(Cursor cursor){
Cursor oldCursor = swapCursor(cursor);
if (oldCursor != null){
oldCursor.close();
}
}
private LibraryModel getData(int position){
mCursor.moveToPosition(position);
String title = mCursor.getString(mCursor.getColumnIndex(DatabaseContract.LibraryEntry.COLUMN_TITLE));
int num = mCursor.getInt(mCursor.getColumnIndex(DatabaseContract.LibraryEntry.COLUMN_NUMBER));
LibraryModel item = new LibraryModel();
item.setTitle(title);
item.setNum(num);
return item;
}
}
And on the fragment:
#Nullable
#Override
public View onCreateView(LayoutInflater inflater, #Nullable ViewGroup container, #Nullable Bundle savedInstanceState) {
View root = inflater.inflate(R.layout.fragment_alltracks, container, false);
libraryRecyclerview = (RecyclerView) root.findViewById(R.id.list);
RecyclerView.LayoutManager mLayoutManager = new LinearLayoutManager(getContext());
libraryRecyclerview.setLayoutManager(mLayoutManager);
mAdapter = new LibraryAdapter(getContext(), null, allTracks);
libraryRecyclerview.setAdapter(mAdapter);
return root;
}
#Override
public void onActivityCreated(#Nullable Bundle savedInstanceState) {
super.onActivityCreated(savedInstanceState);
getLoaderManager().initLoader(1, null, this);
}
#Override
public Loader<Cursor> onCreateLoader(int id, Bundle args) {
Uri uri = DatabaseContract.LibraryEntry.CONTENT_URI;
String[] projection = {
DatabaseContract.LibraryEntry.TABLE_NAME + "." + DatabaseContract.LibraryEntry._ID,
DatabaseContract.LibraryEntry.COLUMN_TITLE,
DatabaseContract.LibraryEntry.COLUMN_NUM
};
return new CursorLoader(getContext(), uri, projection, null, null, null);
}
#Override
public void onLoadFinished(Loader<Cursor> loader, Cursor data) {
mAdapter.changeCursor(data);
}
#Override
public void onLoaderReset(Loader<Cursor> loader) {
mAdapter.changeCursor(null);
}

For anyone still stumbling into this question:
I had the same problem, repeating the same 5 entries in my recycler view.
What fixed my problem was simply to remove
adapter.setHasStableIds(true)
Granted, this got me up to other problems, but I managed to display all my entries with this.

CursorAdapter doesnt want to update

I made the delete posibility from cursor , the function works , but CursorAdapter doesnt update on notifyDataSetChanged(), any one has any idea ??? The only way at the moment to see the changes is to exit app and run again
public class DiaryFragment extends Fragment implements LoaderManager.LoaderCallbacks<Cursor>, AdapterView.OnItemClickListener {

}
private class DiaryAdapter extends CursorAdapter {
private final LayoutInflater mLayoutInflater;

final ImageView deleteDiaryEntry;
deleteDiaryEntry = (ImageView) view.findViewById(R.id.remove_registry_from_diary);
deleteDiaryEntry.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
getActivity().getContentResolver().delete(ContentProvider. URI, " _id = ? ", new String[]{"" + idCraving});
getAdapter().notifyDataSetChanged();
}
});
}
}
}

Within the delete() method in your ContentProvider, you need to have the following line of code:
getContext().getContentResolver().notifyChange(uri, null);
From the official documentation, this line will notify CursorAdapter objects that a change occurred. If you do not have this line, you will see the change only when the code does a fresh lookup of the database which occurs when you exit and reopen the app.

Buttons in listview with simplecursoradapter

can you help me with simple eample? I have listitem with textboxes and 2 iagebutton, how i can bind listeners to my buttons without writing new custom adapter by null(i hope override just simplecursoradapter).
Sorry for my hard english, and i hope, that you give me clear and simple for understanding examples.
public class MainActivity extends FragmentActivity implements LoaderCallbacks<Cursor> {
ListView lvForms;
dbForm table_form;
SimpleCursorAdapter scAdapter;
/**
* Called when the activity is first created.
*/
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
table_form=new dbForm(this);
table_form.open();
String[] from = new String[]{DBHelper.FORM_NAME, DBHelper.FORM_TITLE};
int[] to = new int[]{R.id.tvFormName, R.id.tvFormTitle};
scAdapter = new SimpleCursorAdapter(this, R.layout.listform_item, null, from, to, 0);
lvForms = (ListView) findViewById(R.id.lvForms);
lvForms.setAdapter(scAdapter);
registerForContextMenu(lvForms);
getSupportLoaderManager().initLoader(0, null, this);
}
// обработка нажатия кнопки
public void onButtonClick(View view) {
Intent intent = new Intent(MainActivity.this, LoginActivity.class);
startActivity(intent);
}
protected void onDestroy() {
super.onDestroy();
table_form.close();
}
#Override
public Loader<Cursor> onCreateLoader(int id, Bundle bndl) {
return new MyCursorLoader(this, table_form);
}
#Override
public void onLoadFinished(Loader<Cursor> loader, Cursor cursor) {
scAdapter.swapCursor(cursor);
}
#Override
public void onLoaderReset(Loader<Cursor> loader) {
}
static class MyCursorLoader extends CursorLoader {
dbForm table_form;
public MyCursorLoader(Context context, dbForm table_form) {
super(context);
this.table_form = table_form;
}
#Override
public Cursor loadInBackground() {
Cursor cursor = table_form.getAllData();
return cursor;
}
}
}
UPD: i write custom class
class MySimpleCursorAdapter extends SimpleCursorAdapter {
public MySimpleCursorAdapter(Context context, int layout, Cursor c, String[] from, int[] to, int flags) {
super(context, layout, c, from, to, flags);
}
#Override
public View getView(int position, View convertView, ViewGroup parent) {
if (convertView != null) {
return convertView;
}
return LayoutInflater.from(context).inflate(R.layout.listform_item);
}
#Override
public void bindView(View view, Context context, Cursor cursor) {
String name = cursor.getString(cursor.getColumnIndex(DBHelper.FORM_NAME));
TextView text = (TextView) findViewById(R.id.tvFormName);
text.setText(name);
Button yourButton = (Button) findViewById(R.id.ibtnDelete);
yourButton.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
}
});
}
}
but have error on return LayoutInflater.from(context).inflate(R.layout.listform_item); and can you tell me how now use listener for button(for delete item, for example)? how get number of item where we click on button?

Don`t use getView in overriding the simple cursor adapter and other cursor adapters. You must override the newView and bindView methods.
Here is my working code
public View newView(Context _context, Cursor _cursor, ViewGroup parent) {
LayoutInflater inflater = (LayoutInflater) _context.getSystemService(_context.LAYOUT_INFLATER_SERVICE);
View view = inflater.inflate(R.layout.listform_item, parent, false);
return view;
}
#Override
public void bindView(View view, Context Context, Cursor cursor) {
String name = cursor.getString(cursor.getColumnIndex(DBHelper.FORM_NAME));
String title = cursor.getString(cursor.getColumnIndex(DBHelper.FORM_TITLE));
TextView formname = (TextView) view.findViewById(R.id.tvFormName);
formname.setText(name);
TextView formtitle = (TextView) view.findViewById(R.id.tvFormTitle);
formtitle.setText(title);
ImageButton yourButton = (ImageButton) view.findViewById(R.id.ibtnDelete);
yourButton.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
if (view != null) {
Object obj = view.getTag();
//if(obj != null && obj instanceof Integer) {
dbForm form = new dbForm(context);
form.open();
String st = obj.toString();
form.deleteForm(Long.valueOf(st).longValue());
Toast.makeText(context, "Delete row with id = " + st, Toast.LENGTH_LONG).show();
}
}
});
Object obj = cursor.getString(cursor.getColumnIndex(DBHelper.FORM_ID));
yourButton.setTag(obj);
}

You have to subclass SimpleCursorAdapter.
Override two methods getView and bindView:
#Override
public View getView(int position, View convertView, ViewGroup parent) {
if (convertView != null) {
return convertView;
}
return LayoutInflater.from(context).inflate( R.layout.listform_item);
}
#Override
public void bindView(View view, Context context, Cursor cursor) {
String name = cursor.getString(cursor.getColumnIndex(DBHelper.FORM_NAME));
TextView text = (TextView) viewfindViewById(R.id.tvFormName);
text.setText(name );
Button yourButton = (Button) viewfindViewById(R.id.magic_button);
yourButton.setOnClickListener(new View.OnClickListener(){ //implement listener here});
}

The problem might be here. Its just an assumption. Sorry if I am wrong.
#Override
public int getCount() {
return count;
}
What is the value of count here. I don't find any place where you have passed the value for count.So my assumption is that, the default value for int is returned here (i.e count=0) and hence you don't find any data in your GridView.
Could you check that and comment back.
