    <p>I am making an Android quiz application and I would like for it to have a timer.. 15 seconds. When the timer finishes it moves to a new question. I really did not tried anything because I really don't have a clue, except a choronometer but it seems like a bad solution... the code:</p> <p>I have added this code for a countdown... and you see when it finishes it goes to a method generateQuestion().. now it generates a new question but the answers are mixed up.. it shows answer from some other questions.. How do I solve this?</p> <pre><code>package com.matej.hajdukkviz; import java.util.ArrayList; import java.util.Collections; import java.util.List; import java.util.Random; import com.google.ads.AdRequest; import com.google.ads.AdView; import android.os.Bundle; import android.app.Activity; import android.content.Intent; import android.graphics.Color; import android.view.View; import android.view.Window; import android.view.WindowManager; import android.view.View.OnClickListener; import android.widget.Button; import android.widget.TextView; public class Glavno extends Activity implements OnClickListener { int score = 0; int counter = 0; boolean ajme = true; TextView textView1, textView2, textView3, countdown; Button btn1, btn2, btn3, btn4; ArrayList&lt;Question&gt; qsts = new ArrayList&lt;Question&gt;(); List&lt;Integer&gt; generated = new ArrayList&lt;Integer&gt;(); ArrayList&lt;String&gt; allAnswers = new ArrayList&lt;String&gt;(); Random rng = new Random(); Question nextQuestion; Question qjedan = new Question( "Q1", "Correct answer - q1", "Wrong answer 3 - q1", "Wrong answer 3 - q1", "Wrong answer 3 - q1" ); Question q2 = new Question( "Q2", "Correct answer - q2", "Wrong answer 3 - q2", "Wrong answer 3 - q2", "Wrong answer 3 - q2" ); Question q3 = new Question( "Q3", "Correct answer - q3", "Wrong answer 3 - q3", "Wrong answer 3 - q3", "Wrong answer 3 - q3" ); @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); requestWindowFeature(Window.FEATURE_NO_TITLE); getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN, WindowManager.LayoutParams.FLAG_FULLSCREEN); setContentView(R.layout.pitanja); // ADD THE QUESTIONS IN THE ArrayList qsts new CountDownTimer(20000, 1000) { public void onTick(long millisUntilFinished) { textView4.setText("Seconds remaining: " + millisUntilFinished / 1000); } public void onFinish() { generateQuestion(); textView2.setText("VRIJEME!"); textView2.setTextColor(Color.RED); } }.start(); qsts.add(qjedan); qsts.add(q2); qsts.add(q3); textView1 = (TextView) findViewById(R.id.textView1); textView2 = (TextView) findViewById(R.id.textView2); textView3 = (TextView) findViewById(R.id.textView3); textView3.setText("Rezultat: " + score); btn1 = (Button) findViewById(R.id.btn1); btn2 = (Button) findViewById(R.id.btn2); btn3 = (Button) findViewById(R.id.btn3); btn4 = (Button) findViewById(R.id.btn4); btn1.setOnClickListener(this); btn2.setOnClickListener(this); btn3.setOnClickListener(this); btn4.setOnClickListener(this); generateQuestion(); } public void generateQuestion(){ while(ajme = true){ int nxt = rng.nextInt(3); if (!generated.contains(nxt)){ generated.add(nxt); nextQuestion = qsts.get(nxt); textView1.setText(nextQuestion.questionText); allAnswers.add(nextQuestion.correctAnswerText); allAnswers.add(nextQuestion.wrongAnswer1); allAnswers.add(nextQuestion.wrongAnswer2); allAnswers.add(nextQuestion.wrongAnswer3); Collections.shuffle(allAnswers); btn1.setText(allAnswers.get(0)); btn2.setText(allAnswers.get(1)); btn3.setText(allAnswers.get(2)); btn4.setText(allAnswers.get(3)); break; } } } @Override public void onClick(View v) { Button b = (Button)v; String buttonText = b.getText().toString(); if (counter == 3) { Intent theIntent = new Intent(this, Score.class); theIntent.putExtra("somename", score); startActivity(theIntent); finish(); // Added this method call } else if(buttonText.equals(nextQuestion.correctAnswerText)) { counter++; AdView ad = (AdView) findViewById(R.id.ads); ad.loadAd(new AdRequest()); textView2.setText("TOČNO!"); textView2.setTextColor(Color.GREEN); textView3.setText("Rezultat: " + (score += 10)); allAnswers.clear(); generateQuestion(); return; } else{ counter++; AdView ad = (AdView) findViewById(R.id.ads); ad.loadAd(new AdRequest()); textView2.setText("NETOČNO!"); textView2.setTextColor(Color.RED); textView3.setText("Rezultat: " + (score -= 5)); allAnswers.clear(); generateQuestion(); return; } } </code></pre> <p>}</p>

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.
