Infinite Scroll is loading the same last value always

I managed to retrieve the data from firebase, implementing an infinite scroll... is working right but when i scroll till end, is loading the same last values always..
Tried to change the .limitToLast to .startAt but there is no difference.
private void isScrollCompleted() {
if (totalItem - currentFirstVisibleItem == currentVisibleItemCount
&& this.currentScrollState == SCROLL_STATE_IDLE) {
/** To do code here*/
oldestPostId = oldDummy;
Query query = SearchRef.orderByKey();
if (oldestPostId != null) {
query = query.limitToLast(limitToLast).endAt(oldestPostId);
}
dataList.clear();
query.addListenerForSingleValueEvent(new ValueEventListener() {
#Override
public void onDataChange(DataSnapshot dataSnapshot) {
Query ordenar = mDatabase.child("Off-Topic").orderByChild("countthreads");
for (DataSnapshot child : dataSnapshot.getChildren()) {
MessageThread messageThread = child.getValue(MessageThread.class);
if (messageThread != null) {
oldestPostId = child.getKey();
oldestPostidScrollList.add(child.getKey());
if (oldestPostidScrollList.size() > m) {
String myIdss = oldestPostidScrollList.get(m);
oldDummy = myIdss;
}
messageThread.thread_id = child.getKey();
}
dataList.add(messageThread);
if (dataList.size() == 5) {
Collections.reverse(dataList);
for (int j = 0; j < dataList.size(); j++) {
threadsList.add(dataList.get(j));
}
threadsAdapter = new ThreadsAdapter(ThreadsActivity.this, R.layout.threads_listview,
threadsList, tryList, ThreadsActivity.this, ordenar);
progressBar.setVisibility(View.VISIBLE);
new Handler().postDelayed(new Runnable() {
#Override
public void run() {
progressBar.setVisibility(View.GONE);
}
}, 1000);
threadsListView.setSelection(scrollTO);
} else {
if (lastValueCalled) {
lastValueCalled = true;
for (int j = 0; j < dataList.size(); j++) {
threadsList.add(dataList.get(j));
}
scrollMyListViewToBottom();
}
}
}
scrollTO = scrollTO + 10;
int x = tryList.size();
int temp = x - m;
int count = temp - 10;
if (count > 10 && temp > 10) {
m = m + 10;
} else if (nCalled) {
Log.e("called", "data is over");
} else {
lastValueCalled = true;
if (lastValueCalled) {
nCalled = true;
}
}
}
#Override
public void onCancelled(DatabaseError databaseError) {
}
});
Also checked the log and is giving the result "data is over" but continues doing the same thing always. Any clue?

I wanted to make the java code as simple as I can so I've just added the lines for my question. What I'm trying to do is
android:onClick="onePointForTeamA"make this button only clickable when foulCounterA = 5 Failed to add if (foulCounterA = 5); inside public void foulCountForTeamA(View v) {
It gave me an error that way. Says required: boolean, found: int.
What should I do with the code? Any help will be appreeciated

Regarding your concrete question, the syntax of if (foulCounterA = 5); is wrong, because the equation check is have to made by == operator.
So the correct syntax would be if (foulCounterA == 5);
As #OH GOD SPIDERS wrote in the comment, you should check the basics of java operators.
Also I recommend You to search for the answer before asking a new question.

How to trigger alert

My source code is here https://github.com/jackygrahamez/MayDay
I have a HomeActivity.java with an onCreate method
...
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.welcome_screen);
Bundle bundle=getIntent().getExtras();
boolean startedByCUP=false;
if(bundle!=null) {
Log.e(">>>>>>", "START_BY_CUP");
startedByCUP = bundle.getBoolean("START_BY_CUP");
}
...
I am trying to figure out how I can tie the condition where bundle is true to trigger the multiClickEvent so that after 5 clicks an alarm will trigger. The hardware trigger is built into this
HardwareTriggerReceiver.java
...
#Override
public void onReceive(Context context, Intent intent) {
Log.e(">>>>>>>", "in onReceive of HWReceiver");
String action = intent.getAction();
if (!isCallActive(context) && isScreenLocked(context)
&& (action.equals(ACTION_SCREEN_OFF) ||
action.equals(ACTION_SCREEN_ON))) {
multiClickEvent.registerClick(System.currentTimeMillis());
if (multiClickEvent.isActivated()) {
onActivation(context);
resetEvent();
}
}
}
...
MultiClickEvent.java
package com.mayday.md.trigger;
import android.util.Log;
public class MultiClickEvent {
public static final int TIME_INTERVAL = 10000;
private static final int TOTAL_CLICKS = 5;
private Long firstEventTime;
private int clickCount = 0;
public void reset() {
firstEventTime = null;
clickCount = 0;
}
public void registerClick(Long eventTime) {
if (isFirstClick() || notWithinLimit(eventTime)) {
firstEventTime = eventTime;
clickCount = 1;
return;
}
clickCount++;
Log.e(">>>>>>", "MultiClickEvent clickCount = " + clickCount);
}
private boolean notWithinLimit(long current) {
return (current - firstEventTime) > TIME_INTERVAL;
}
private boolean isFirstClick() {
return firstEventTime == null;
}
public boolean isActivated() {
return clickCount >= TOTAL_CLICKS;
}
}
I have tried creating an instance of MultiClickEvent into the HomeActivity but that did not track the clicks.

I ended up tracking the clicks on the Gear Fit app and then sending the alarm all within the onCreate
if(bundle!=null) {
if (!hardwareTriggerReceiver.isCallActive(getApplicationContext())) {
int c = mPref.getInt("numRun", 0);
int TIME_INTERVAL = 10000;
int TOTAL_CLICKS = 5;
long delta = 0;
Long eventTime = System.currentTimeMillis();
mPref.edit().putLong("eventTime", eventTime).commit();
Long firstEventTime = mPref.getLong("firstEventTime", 0);
if (firstEventTime == 0) {
firstEventTime = eventTime;
mPref.edit().putLong("firstEventTime", firstEventTime).commit();
}
delta = eventTime - firstEventTime;
Log.e(">>>>>>", "START_BY_CUP delta "+delta);
if (delta < TIME_INTERVAL) {
c++;
mPref.edit().putInt("numRun",c).commit();
Log.e(">>>>>>", "START_BY_CUP "+c);
if (c >=TOTAL_CLICKS) {
hardwareTriggerReceiver.onActivation(getApplicationContext());
mPref.edit().putInt("numRun", 0).apply();
mPref.edit().putLong("firstEventTime", 0).apply();
}
} else {
mPref.edit().putInt("numRun", 0).apply();
mPref.edit().putLong("firstEventTime", 0).apply();
}
}
}

2 identical records being entered in SQLite db at one time - Android

After each trivia game is over, the Results page displays. After about 20 seconds, which is how long each question gives you during the game before your time runs out and it goes to the next question, the Results page reloads. Then when you go to the Highscores page, the score has been entered twice. So something is screwed up in my QuestionView class below but I cannot find the bug.
If any further information is needed let me know. Thank you in advanced!
Results.java
total_score = dh.calculateTotalScore(score, percentage);
if(dh.getLowest() == -1) {
dh.insert(score, percentage, total_score, category);

}

public long insert(long score, int percentage, long total_score, String category) {
ContentValues values = new ContentValues();
values.put(SCORE, score);
values.put(PERCENTAGE, percentage);
values.put(TOTAL_SCORE, total_score);
values.put(CATEGORY, category);
return db.insert(TABLE, null, values);
}
public void delete(long lowScore) {
lowScore = getLowest();
db.delete(TABLE, TOTAL_SCORE + "=" + lowScore, null);
}
public long getLowest() {
Cursor c = db.rawQuery("SELECT * FROM " + TABLE + " ORDER BY " + TOTAL_SCORE, null);
long count = c.getCount();
long lowScore = -1;
if(count == 10) {
c.moveToLast();
lowScore = c.getInt(c.getColumnIndex(TOTAL_SCORE));
}
return lowScore;
}
public long calculateTotalScore(long score, int percentage) {
long i;
return i = (percentage * 1000) + score;
}

}
THE FIX:
Changed:
if(i == 10) {
endQuiz();
}
...to this:
if(i == 10) {
cdTimer.cancel();
endQuiz();
}**

Probably endQuiz gets called twice. And only when you answer the last question before the timer is up.
Because, I don't see you canceling the timer when you answer the last question. So, even though you answered already, the timer is still ticking, and when it is up, it will call endQuiz.
If you don't answer the last question and let the time run out, then the result will be inserted only once, because endQuiz will be called only once, from the timer.

Achartengine's piechart does not refresh from repaint function

I'm building an application that makes piechart from database according to precise date interval. Unfortunately the achartengine's repaint function is not working when I'm stepping with the buttons.
When the Activity starts everything is fine the chart is okay but when i'm using the buttons then nothing happens.
I hope somebody can help me.
here is the code:
private GraphicalView chartView;

I have not used Achart but this is a simple pie chart implementation. You can refer the demo and it might help.
In this demo after you update the values, you need to call invalidate() to redraw the pie chart.
