/**
 * This method collapses the view that was clicked and animates all the
 * views around it to close around the collapsing view. There are several
 * steps required to do this which are outlined below.
 * <p/>/*w w  w . jav  a  2s .c o  m*/
 * 1. Update the layout parameters of the view clicked so as to minimize its
 * height to the original collapsed (default) state. 2. After invoking a
 * layout, the listview will shift all the cells so as to display them most
 * efficiently. Therefore, during the first predraw pass, the listview must
 * be offset by some amount such that given the custom bound change upon
 * collapse, all the cells that need to be on the screen after the layout
 * are rendered by the listview. 3. On the second predraw pass, all the
 * items are first returned to their original location (before the first
 * layout). 4. The collapsing view's bounds are animated to what the final
 * values should be. 5. The bounds above the collapsing view are animated
 * downwards while the bounds below the collapsing view are animated
 * upwards. 6. The extra text is faded out as its contents become visible
 * throughout the animation process.

 * <p/>/*from  w w w . j a  va  2 s  .  c  om*/
 * 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.

/**

 * <p/>//from  w  w w.j  a v  a 2  s.co m
 * 1. Update the layout parameters of the view clicked so as to minimize its
 * height to the original collapsed (default) state. 2. After invoking a
 * layout, the listview will shift all the cells so as to display them most
 * efficiently. Therefore, during the first predraw pass, the listview must
 * be offset by some amount such that given the custom bound change upon
 * collapse, all the cells that need to be on the screen after the layout
 * are rendered by the listview. 3. On the second predraw pass, all the
 * items are first returned to their original location (before the first
 * layout). 4. The collapsing view's bounds are animated to what the final
 * values should be. 5. The bounds above the collapsing view are animated
 * downwards while the bounds below the collapsing view are animated
 * upwards. 6. The extra text is faded out as its contents become visible
 * throughout the animation process.
