    <p>I have a trivia game that displays 10 questions and they each have a 10 second timer. I have 2 problems that do not function correctly. </p> <p>Firstly, If the timer runs out on a question, it displays the next question but the timer does not reset. The textviews stay at "Time's up!" and "Time Elapsed: 10000" instead of restarting the timer on the new question that is displayed.</p> <p>Lastly, on the Results page the correct score is not displayed in the textview. The percentage textview displays correctly but the score textview displays "android.widget.TextView@416473c" or some other random memory location.</p> <p>The program never crashes just functions incorrectly. Any code structure or other suggestions is much appreciated! This is my first android mobile app attempt and I am slowly and strugglingly through it. Yet enjoying it! :)</p> <p>QuesteionView.java</p> <pre><code>public class QuestionView extends Activity { @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.questionviewmain); answer1 = (Button)findViewById(R.id.answer1); answer2 = (Button)findViewById(R.id.answer2); answer3 = (Button)findViewById(R.id.answer3); answer4 = (Button)findViewById(R.id.answer4); question = (TextView)findViewById(R.id.question); queries = getIntent().getParcelableArrayListExtra("queries"); timer = (TextView)findViewById(R.id.timer); timeElapsedView = (TextView)findViewById(R.id.timeElapsedView); cdTimer = new Timer(startTime, interval); loadQuestion(); } public void loadQuestion() { if(i == 9) { endQuiz(); } else { if(!timerHasStarted) { cdTimer.start(); timerHasStarted = true; } else { cdTimer.cancel(); timerHasStarted = false; } answer = queries.get(i).getCorrectAnswer(); question.setText(queries.get(i).getQuery()); answer1.setText(queries.get(i).getA1()); answer2.setText(queries.get(i).getA2()); answer3.setText(queries.get(i).getA3()); answer4.setText(queries.get(i).getA4()); answer1.setOnClickListener(new OnClickListener() { public void onClick(View arg0) { queries.get(i).setSelectedAnswer(0); if(answer == 0) { correctAnswers++; nextQuestion(); } else { wrongAnswers++; nextQuestion(); } } }); //same type of code for buttons for answers 2 through 4. } } public void nextQuestion() { score = score + timeElapsed; i++; loadQuestion(); } public class Timer extends CountDownTimer { public Timer(long startTime, long interval) { super(startTime, interval); } public void onFinish() { if(i == 9) { cdTimer.cancel(); } else { timer.setText("Time's up!"); timeElapsedView.setText("Time Elapsed: " + String.valueOf(startTime)); wrongAnswers++; nextQuestion(); } } public void onTick(long millisUntilFinished) { timer.setText("Time remain: " + Long.toString(millisUntilFinished)); timeElapsed = startTime - millisUntilFinished; timeElapsedView.setText("Time Elapsed: " + Long.toString(timeElapsed)); } } public void endQuiz() { Intent intent = new Intent(QuestionView.this, Results.class); intent.putExtra("correctAnswers", correctAnswers); intent.putExtra("wrongAnswers", wrongAnswers); intent.putExtra("score", score); intent.putParcelableArrayListExtra("queries", queries); startActivity(intent); } } </code></pre> <p>Results.java</p> <pre><code> public class Results extends Activity { QuestionView qv = new QuestionView(); ArrayList&lt;Question&gt; queryList = qv.getQueries(); int cAnswers; int wAnswers; long score; ArrayList&lt;Question&gt; qs; @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.resultsmain); cAnswers = getIntent().getIntExtra("correctAnswers", -1); wAnswers = getIntent().getIntExtra("wrongAnswers", -1); score = getIntent().getLongExtra("score", -1); qs = getIntent().getParcelableArrayListExtra("queries"); Button mainmenuBtn = (Button)findViewById(R.id.mainmenuBtn); mainmenuBtn.setText("Main Menu"); mainmenuBtn.setOnClickListener(new OnClickListener() { public void onClick(View arg0) { restart(); } }); showResults(); } public void showResults() { ArrayList&lt;TextView&gt; tList = new ArrayList&lt;TextView&gt;(9); TextView header = (TextView)findViewById(R.id.header); header.setText("SUMMARY"); TextView percentage = (TextView)findViewById(R.id.percentage); percentage.setText(Integer.toString(10 * cAnswers) + "%"); TextView score = (TextView)findViewById(R.id.score); String s = "" + score; score.setText(s); TextView q1 = (TextView)findViewById(R.id.q1); TextView q2 = (TextView)findViewById(R.id.q2); TextView q3 = (TextView)findViewById(R.id.q3); TextView q4 = (TextView)findViewById(R.id.q4); TextView q5 = (TextView)findViewById(R.id.q5); TextView q6 = (TextView)findViewById(R.id.q6); TextView q7 = (TextView)findViewById(R.id.q7); TextView q8 = (TextView)findViewById(R.id.q8); TextView q9 = (TextView)findViewById(R.id.q9); TextView q10 = (TextView)findViewById(R.id.q10); tList.add(q1); tList.add(q2); tList.add(q3); tList.add(q4); tList.add(q5); tList.add(q6); tList.add(q7); tList.add(q8); tList.add(q9); tList.add(q10); for(int i = 0; i &lt; tList.size(); i++) { tList.get(i).setText(qs.get(i).getQuery()); if(qs.get(i).getSelectedAnswer() == qs.get(i).getCorrectAnswer()) { tList.get(i).setTextColor(Color.GREEN); } else { tList.get(i).setTextColor(Color.RED); } } } public void restart() { Intent intent = new Intent(Results.this, MainMenu.class); startActivity(intent); } } </code></pre>

    1. COYou've posted huge amounts of code, but you've given no indication of what you've tried to fix the problem. Additionally, your title refers to an exception - but there's no mention of it in your question body.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
