    <p>I'm building a quiz app. It is going to get 20 random questions from a database. What I'm looking to do is put the number of questions above each question. Something like "Question 10/20" when its on question 10. Any Ideas?</p> <p>Some of the code is below.</p> <pre><code>import java.util.List; import android.app.Activity; import android.content.Intent; import android.os.Bundle; import android.view.KeyEvent; import android.view.View; import android.view.View.OnClickListener; import android.widget.Button; import android.widget.RadioButton; import android.widget.TextView; import com.tmm.android.chuck.quiz.GamePlay; import com.tmm.android.chuck.quiz.Question; import com.tmm.android.chuck.util.Utility; /** * @author Derek McAuley * */ public class QuestionActivity extends Activity implements OnClickListener{ private Question currentQ; private GamePlay currentGame; @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.question); /** * Configure current game and get question */ currentGame = ((ChuckApplication)getApplication()).getCurrentGame(); currentQ = currentGame.getNextQuestion(); TextView num = (TextView) findViewById(R.id.textView1); Button nextBtn = (Button) findViewById(R.id.nextBtn); nextBtn.setOnClickListener(this); /** * Update the question and answer options.. */ setQuestions(); } /** * Method to set the text for the question and answers from the current games * current question */ private void setQuestions() { //set the question text from current question String question = Utility.capitalise(currentQ.getQuestion()) + "?"; TextView qText = (TextView) findViewById(R.id.question); qText.setText(question); //set the available options List&lt;String&gt; answers = currentQ.getQuestionOptions(); TextView option1 = (TextView) findViewById(R.id.answer1); option1.setText(Utility.capitalise(answers.get(0))); TextView option2 = (TextView) findViewById(R.id.answer2); option2.setText(Utility.capitalise(answers.get(1))); TextView option3 = (TextView) findViewById(R.id.answer3); option3.setText(Utility.capitalise(answers.get(2))); TextView option4 = (TextView) findViewById(R.id.answer4); option4.setText(Utility.capitalise(answers.get(3))); } @Override public void onClick(View arg0) { //Log.d("Questions", "Moving to next question"); /** * validate a checkbox has been selected */ if (!checkAnswer()) return; /** * check if end of game */ if (currentGame.isGameOver()){ //Log.d("Questions", "End of game! lets add up the scores.."); //Log.d("Questions", "Questions Correct: " + currentGame.getRight()); //Log.d("Questions", "Questions Wrong: " + currentGame.getWrong()); Intent i = new Intent(this, EndgameActivity.class); startActivity(i); finish(); } else{ Intent i = new Intent(this, QuestionActivity.class); startActivity(i); finish(); } } @Override public boolean onKeyDown(int keyCode, KeyEvent event) { switch (keyCode) { case KeyEvent.KEYCODE_BACK : return true; } return super.onKeyDown(keyCode, event); } /** * Check if a checkbox has been selected, and if it * has then check if its correct and update gamescore */ private boolean checkAnswer() { String answer = getSelectedAnswer(); if (answer==null){ //Log.d("Questions", "No Checkbox selection made - returning"); return false; } else { //Log.d("Questions", "Valid Checkbox selection made - check if correct"); if (currentQ.getAnswer().equalsIgnoreCase(answer)) { //Log.d("Questions", "Correct Answer!"); currentGame.incrementRightAnswers(); } else{ //Log.d("Questions", "Incorrect Answer!"); currentGame.incrementWrongAnswers(); } return true; } } /** * */ private String getSelectedAnswer() { RadioButton c1 = (RadioButton)findViewById(R.id.answer1); RadioButton c2 = (RadioButton)findViewById(R.id.answer2); RadioButton c3 = (RadioButton)findViewById(R.id.answer3); RadioButton c4 = (RadioButton)findViewById(R.id.answer4); if (c1.isChecked()) { return c1.getText().toString(); } if (c2.isChecked()) { return c2.getText().toString(); } if (c3.isChecked()) { return c3.getText().toString(); } if (c4.isChecked()) { return c4.getText().toString(); } return null; } } </code></pre>

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.
