RecycleView doesn't show all the information
Question
I have an RecycleView and it which shows the events that will happen in future and it worked fine (all the information showed up) but after that i added 2 more buttons to the layout after running it i had fewer events and i don't know why(i didn't change any code in the java file)
here is my code:
private void setupAdaptaterNew() {
mPostAdapterNew = new FirebaseRecyclerAdapter<Post, PostViewHolder>(
Post.class,
R.layout.item_layout_evenimente,
PostViewHolder.class,
mPostRef
) {
@Override
public void populateViewHolder(final PostViewHolder viewHolder, final Post model, final int position) {
final int EndOra = viewHolder.setEndOra(model.getEndOra());
final long EndZi = viewHolder.setEndZi(model.getEndZi());
final int EndLuna = viewHolder.setEndLuna(model.getEndLuna());
final int EndAn = viewHolder.setEndAn(model.getEndAn());
final ContentResolver cr = getApplicationContext().getContentResolver();
final ContentValues values = new ContentValues();
final ContentResolver crReminder = getApplicationContext().getContentResolver();
final ContentValues[] valuesReminder = {new ContentValues()};
final Uri[] event = new Uri[1];
final String headline = viewHolder.setHeadline(model.getHeadline());
final String locatie = viewHolder.setStrada(model.getStrada());
final String organizator = viewHolder.setOrganizator(model.getOrganizator());
final Button btnDeleteEvent = viewHolder.itemView.findViewById(R.id.BtnNuParticip);
final Button btnAddEvent = viewHolder.itemView.findViewById(R.id.BtnParticip);
final Calendar cal = Calendar.getInstance();
cal.set(Calendar.HOUR, EndOra);
cal.set(Calendar.MINUTE, 0);
cal.set(Calendar.SECOND, 0);
cal.set(Calendar.MILLISECOND, 0);
cal.set(Calendar.MONTH, EndLuna);
cal.set(Calendar.DAY_OF_MONTH, (int) EndZi);
cal.set(Calendar.YEAR, EndAn);
if (Calendar.getInstance().before(cal)) {
StorageReference storageReference = FirebaseStorage.getInstance().getReferenceFromUrl(model.getImageUrl());
Glide.with(Evenimente.this)
.using(new FirebaseImageLoader())
.load(storageReference)
.into(viewHolder.postIV);
viewHolder.setHeadline(model.getHeadline());
viewHolder.setZiua(model.getZiua());
viewHolder.setLuna(model.getLuna());
viewHolder.setOra(model.getOra());
viewHolder.setOrganizator(model.getOrganizator());
viewHolder.setCategoria(model.getCategoria());
viewHolder.setStrada(model.getStrada());
viewHolder.setLocalitatea(model.getLocalitatea());
viewHolder.setPostDescriere(model.getDescriere());
} else {
viewHolder.itemView.setVisibility(View.GONE);
viewHolder.itemView.setLayoutParams(new RecyclerView.LayoutParams(0, 0));
}
btnAddEvent.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View view) {
if (ActivityCompat.checkSelfPermission(getApplicationContext(), Manifest.permission.WRITE_CALENDAR) != PackageManager.PERMISSION_GRANTED ||
ActivityCompat.checkSelfPermission(getApplicationContext(), Manifest.permission.READ_CALENDAR) != PackageManager.PERMISSION_GRANTED) {
Toast.makeText(getApplicationContext(), "Permisii insuficiente.\n Va rugam sa activati permisiunea de CALENDAR", Toast.LENGTH_LONG).show();
} else {
long startMillis = 0;
long endMillis = 0;
//Start and End of event date
Calendar beginTime = Calendar.getInstance();
beginTime.set(EndAn, EndLuna, (int) EndZi, EndOra, 0);
startMillis = beginTime.getTimeInMillis();
Calendar endTime = Calendar.getInstance();
endTime.set(EndAn, EndLuna, (int) EndZi, EndOra, 0);
endMillis = endTime.getTimeInMillis();
//Add Values
values.put(Events.DTSTART, startMillis);
values.put(Events.TITLE, headline);
values.put(Events.DESCRIPTION, "Description"); //TODO change description here!
TimeZone timeZone = TimeZone.getDefault();
values.put(Events.EVENT_TIMEZONE, timeZone.getID());
values.put(Events.CALENDAR_ID, 1);
values.put(Events.DTEND, endMillis);
values.put(Events.EVENT_LOCATION, locatie);
values.put(Events.ORGANIZER, organizator);
event[0] = cr.insert(Events.CONTENT_URI, values);
valuesReminder[0].put(CalendarContract.Reminders.DTSTART, startMillis);
Uri REMINDERS_URI_DAY = Uri.parse(getCalendarUriBase(true) + "reminders");

createDialogAddEvent(headline);
btnDeleteEvent.setVisibility(View.VISIBLE);
btnAddEvent.setVisibility(View.GONE);
}
}
});
btnDeleteEvent.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View view) {
Uri deleteUri = null;
deleteUri = ContentUris.withAppendedId(CalendarContract.Events.CONTENT_URI, Long.parseLong(event[0].getLastPathSegment()));

//Create Dialog;
createDialogDeleteEvent(headline);
}
});
}
};
}
private String getCalendarUriBase(boolean eventUri) {
Uri calendarURI = null;
try {
if (android.os.Build.VERSION.SDK_INT <= 7) {
calendarURI = (eventUri) ? Uri.parse("content://calendar/") : Uri.parse("content://calendar/calendars");
} else {
calendarURI = (eventUri) ? Uri.parse("content://com.android.calendar/") : Uri
.parse("content://com.android.calendar/calendars");
}
} catch (Exception e) {
e.printStackTrace();
}
return calendarURI.toString();
}
And this is my RecycleView model:

Close The CardView, you have opened a CardView at the top of the xml file but did not close it.
Add this to the End of the file
</android.support.v7.widget.CardView>
I hope that helps.

You've set the height of inner LinearLayout to match_parent which is using all the space and buttons are not showing up.
Try this:
<?xml version="1.0" encoding="utf-8"?>
<android.support.v7.widget.CardView
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_margin="4dp">
<LinearLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_marginLeft="1dp"
android:layout_marginRight="1dp"
android:gravity="center_vertical|right"
android:orientation="vertical">
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content" // Change it to wrap_content
android:orientation="vertical">
....
</LinearLayout>
<TextView
android:id="@+id/DescriereEveniment"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_marginTop="20dp"
android:clickable="true"
android:autoLink="web"
android:visibility="gone" />
<Button
android:id="@+id/BtnParticip"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:text="Particip!"
/>
<Button
android:id="@+id/BtnNuParticip"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:text="Nu m-ai particip"
/>
</LinearLayout>
</android.support.v7.widget.CardView>
