From source file:com.example.mike.birdalarm.ExpandingListView.java

/**
 * This method expands the view that was clicked and animates all the views
 * around it to make room for the expanding view. There are several steps
 * required to do this which are outlined below.
 * <p/>/*from w w w  .ja va 2s.  c  o  m*/
 * 1. Store the current top and bottom bounds of each visible item in the
 * listview. 2. Update the layout parameters of the selected view. In the
 * context of this method, the view should be originally collapsed and set
 * to some custom height. The layout parameters are updated so as to wrap
 * the content of the additional text that is to be displayed.
 * <p/>
 * After invoking a layout to take place, the listview will order all the
 * items such that there is space for each view. This layout will be
 * independent of what the bounds of the items were prior to the layout so
 * two pre-draw passes will be made. This is necessary because after the
 * layout takes place, some views that were visible before the layout may
 * now be off bounds but a reference to these views is required so the
 * animation completes as intended.
 * <p/>
 * 3. The first predraw pass will set the bounds of all the visible items to
 * their original location before the layout took place and then force
 * another layout. Since the bounds of the cells cannot be set directly, the
 * method setSelectionFromTop can be used to achieve a very similar effect.
 * 4. The expanding view's bounds are animated to what the final values
 * should be from the original bounds. 5. The bounds above the expanding
 * view are animated upwards while the bounds below the expanding view are
 * animated downwards. 6. The extra text is faded in as its contents become
 * visible throughout the animation process.
 * <p/>
 * It is important to note that the listview is disabled during the
 * animation because the scrolling behaviour is unpredictable if the bounds
 * of the items within the listview are not constant during the scroll.

/**
 * This method expands the view that was clicked and animates all the views
 * around it to make room for the expanding view. There are several steps required
 * to do this which are outlined below./*from   w  w  w . j av  a  2  s.  com*/
 *
 * 1. Store the current top and bottom bounds of each visible item in the listview.
 * 2. Update the layout parameters of the selected view. In the context of this
 *    method, the view should be originally collapsed and set to some custom height.
 *    The layout parameters are updated so as to wrap the content of the additional
 *    text that is to be displayed.
 *
 * After invoking a layout to take place, the listview will order all the items
 * such that there is space for each view. This layout will be independent of what
 * the bounds of the items were prior to the layout so two pre-draw passes will
 * be made. This is necessary because after the layout takes place, some views that
 * were visible before the layout may now be off bounds but a reference to these
 * views is required so the animation completes as intended.
 *
 * 3. The first predraw pass will set the bounds of all the visible items to
 *    their original location before the layout took place and then force another
 *    layout. Since the bounds of the cells cannot be set directly, the method
 *    setSelectionFromTop can be used to achieve a very similar effect.
 * 4. The expanding view's bounds are animated to what the final values should be
 *    from the original bounds.
 * 5. The bounds above the expanding view are animated upwards while the bounds
 *    below the expanding view are animated downwards.
 * 6. The extra text is faded in as its contents become visible throughout the
 *    animation process.
 *
 * It is important to note that the listview is disabled during the animation
 * because the scrolling behaviour is unpredictable if the bounds of the items
 * within the listview are not constant during the scroll.
