    <p>I made a simple quiz game for android, right now there's only 10 questions, and 40 answers. (4 answers for each question) Sometimes when I hit a button it gives me more than one correct answer at a time! Any idea what's wrong with this code:</p> <pre><code>public class ETBetaActivity extends Activity implements View.OnClickListener { Button answer_1, answer_2,answer_3, answer_4,main; TextView q_textview, tip; private String a1,a2,a3,a4 = ""; private int i1 = 0; public static int correct = 0; private boolean alive = true; MediaPlayer button_click; private String[] questions = {"Q1", "Q2", "Q3", "Q4", "Q5", //5 "Q6", "Q7", "Q8", "Q9", "Q10" //10 }; public static int question_amount = 10; private String[] answers_correct = {"Correct answer - 1", "Correct answer - 2", "Correct answer - 3", "Correct answer - 4", "Correct answer - 5", "Correct answer - 6", "Correct answer - 7", "Correct answer - 8", "Correct answer - 9", "Correct answer - 10" }; private String[][] answers_wrong = { {"Q1-1", "Q1-2" , "Q1-3"}, {"Q2-1", "Q2-2" , "Q2-3"}, {"Q3-1", "Q3-2" , "Q3-3"}, {"Q4-1", "Q4-2" , "Q4-3"}, {"Q5-1", "Q5-2" , "Q5-3"}, {"Q6-1", "Q6-2" , "Q6-3"}, {"Q7-1", "Q7-2" , "Q7-3"}, {"Q8-1", "Q8-2" , "Q8-3"}, {"Q9-1", "Q9-2" , "Q9-3"}, {"Q10-1", "Q10-2" , "Q10-3"} }; List&lt;String&gt; question_list = new ArrayList&lt;String&gt;(); List&lt;String&gt; answer_list_correct = new ArrayList&lt;String&gt;(); @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.main); getData(); Game(i1); } @Override public void onClick(View view) { if (alive == false) { // startActivity(new Intent("com.aleksei.etb.END")); return; } button_click = MediaPlayer.create(this, R.raw.button_click); button_click.start(); switch(view.getId()){ case R.id.button5: //main break; case R.id.button1: //answer_1 if(isCorrect(1)) correct++; break; case R.id.button2: //answer_2 if(isCorrect(2)) correct++; break; case R.id.button3: //answer_3 if(isCorrect(3)) correct++; break; case R.id.button4: //answer_3 if(isCorrect(4)) correct++; break; default: break; } Game(i1); tip.setText("Correct answers: "+correct); } public static int getResults(){ int value = (int) Math.floor((correct*5)/question_amount); if(value &lt;= 0) return 1; else return value; } private boolean isCorrect(int button){ for (int i = 0; i &lt; answers_correct.length; i++){ if(button == 1 &amp;&amp; a1 == answers_correct[i] || button == 2 &amp;&amp; a2 == answers_correct[i] || button == 3 &amp;&amp; a3 == answers_correct[i] || button == 4 &amp;&amp; a4 == answers_correct[i]) return true; } return false; } private void Game(int q){ if(i1 == question_amount) { //no more questions startActivity(new Intent("com.aleksei.etb.END")); alive = false; return; } try { main.setText("Dunno"); String answer_list[] = { answers_correct[q], answers_wrong[q][0] , answers_wrong[q][1] , answers_wrong[q][2] }; Collections.shuffle(Arrays.asList(answer_list)); answer_1.setText(answer_list[0]); answer_2.setText(answer_list[1]); answer_3.setText(answer_list[2]); answer_4.setText(answer_list[3]); a1 = answer_list[0]; a2 = answer_list[1]; a3 = answer_list[2]; a4 = answer_list[3]; q_textview.setText(questions[q]); } catch (Exception ex){} i1++; } private void getData(){ //Getting the data main = (Button) findViewById(R.id.button5); answer_1 = (Button) findViewById(R.id.button1); answer_2 = (Button) findViewById(R.id.button2); answer_3 = (Button) findViewById(R.id.button3); answer_4 = (Button) findViewById(R.id.button4); q_textview = (TextView) findViewById(R.id.question); tip = (TextView) findViewById(R.id.answ1); //Making the buttons, actually work main.setOnClickListener(this); answer_1.setOnClickListener(this); answer_2.setOnClickListener(this); answer_3.setOnClickListener(this); answer_4.setOnClickListener(this); //Resets the text //Note to self: Replace with another ContectView main.setText("Begin!"); answer_4.setText(""); answer_3.setText(""); answer_2.setText(""); answer_1.setText(""); tip.setText(""); } } </code></pre> <p>I even tried something like</p> <pre><code>private boolean getAnswer = false; private String correctAnswer; private boolean isCorrect(int button){ if(getAnswer == true) { if(button == 1 &amp;&amp; a1 == correctAnswer || button == 2 &amp;&amp; a2 == correctAnswer || button == 3 &amp;&amp; a3 == correctAnswer || button == 4 &amp;&amp; a4 == correctAnswer) return true; } return false; } </code></pre> <p>Inside Game(int) :</p> <pre><code>getAnswer = false; correctAnswer = answers_correct[q]; </code></pre> <p>Didnt help.</p> <p><em>I hope I made my self clear, if not, ask.</em></p> <p>Thanks.</p> <p>Edit: Tried using these in the onCreate method</p> <pre><code>answer_1.setOnClickListener(new View.OnClickListener() { public void onClick(View v) { if(isCorrect(1)) correct++; Game(i1); tip.setText("Correct answers "+correct); } }); answer_2.setOnClickListener(new View.OnClickListener() { public void onClick(View v) { if(isCorrect(2)) correct++; Game(i1); tip.setText("Correct answers "+correct); } }); answer_3.setOnClickListener(new View.OnClickListener() { public void onClick(View v) { if(isCorrect(3)) correct++; Game(i1); tip.setText("Correct answers "+correct); } }); answer_4.setOnClickListener(new View.OnClickListener() { public void onClick(View v) { if(isCorrect(4)) correct++; Game(i1); tip.setText("Correct answers "+correct); } }); </code></pre> <p>Didn't help.</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.
