    <p>I'm creating a Simon Says app for Android. The game has four tiles: red, blue, green, and yellow. When the game starts, the program picks a random number between 1 and 4 (which corresponds to the four colors) and stores it in a string. Each round of play adds a new digit to the string. The program then should then the first character in the string and play a unique sound and brighten the color of the appropriate button for ~1 second before moving on to the next character. Each time the player correctly inputs the pattern, it adds another digit to the string.</p> <p>My problem is this: I have found methods that keep the button brightened for the duration of the sound, but all of them cause the program to execute the entire for loop in the amount of time it takes for the sound to finish playing. Here is my code:</p> <pre><code>case R.id.new_game_button: if (event.getAction() == MotionEvent.ACTION_DOWN) { combination += randomGenerator(); for (int i=0; i &lt; combination.length(); i++) { if (combination.charAt(i) == 49) { findViewById(R.id.red_button).setBackgroundResource(color.red_pressed); red_sound.start(); red_sound.setOnCompletionListener(new OnCompletionListener() { @Override public void onCompletion(MediaPlayer mp) { findViewById(R.id.red_button).setBackgroundResource(color.red); } }); } } } break; </code></pre> <p>I've tried Thread.sleep(), OnCompletionListeners, postDelayed Handlers, and CountDownTimers, but I can't get any of them to do what I need them to do. How might I go about halting the for loop from executing while the sound is playing?</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.
