From source file:android.app.Activity.java

/**
 * Called when a key was pressed down and not handled by any of the views
 * inside of the activity. So, for example, key presses while the cursor 
 * is inside a TextView will not trigger the event (unless it is a navigation
 * to another object) because TextView handles its own key presses.
 * /*from  ww  w. java  2s  .co  m*/
 * <p>If the focused view didn't want this event, this method is called.
 *
 * <p>The default implementation takes care of {@link KeyEvent#KEYCODE_BACK}
 * by calling {@link #onBackPressed()}, though the behavior varies based
 * on the application compatibility mode: for
 * {@link android.os.Build.VERSION_CODES#ECLAIR} or later applications,
 * it will set up the dispatch to call {@link #onKeyUp} where the action
 * will be performed; for earlier applications, it will perform the
 * action immediately in on-down, as those versions of the platform
 * behaved.
 * 
 * <p>Other additional default key handling may be performed
 * if configured with {@link #setDefaultKeyMode}.
 * 
 * @return Return <code>true</code> to prevent this event from being propagated
 * further, or <code>false</code> to indicate that you have not handled 
 * this event and it should continue to be propagated.
 * @see #onKeyUp
 * @see android.view.KeyEvent
