/** * 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 ww.j a v a 2 s. 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. * * 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. */ private void expandView(final View view) { final SuggestionExpandingListViewItem viewObject = (SuggestionExpandingListViewItem) getItemAtPosition( getPositionForView(view)); /* Store the original top and bottom bounds of all the cells.*/ final int oldTop = view.getTop(); final int oldBottom = view.getBottom(); final HashMap<View, int[]> oldCoordinates = new HashMap<View, int[]>(); int childCount = getChildCount(); for (int i = 0; i < childCount; i++) { View v = getChildAt(i); ViewCompat.setHasTransientState(v, true); oldCoordinates.put(v, new int[] { v.getTop(), v.getBottom() }); } /* Update the layout so the extra content becomes visible.*/ final View expandingLayout = view.findViewById(R.id.expanding_layout); expandingLayout.setVisibility(View.VISIBLE); /* Add an onPreDraw Listener to the listview. onPreDraw will get invoked after onLayout * and onMeasure have run but before anything has been drawn.

/** * <p>// w ww. ja v a 2s . c om * 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> * * <li>Store the current top and bottom bounds of each visible item in the listview.</li> <li>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.</li> * * <br/> * <br/> * <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> * <br/> * * <li>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.</li> <li>The * expanding view's bounds are animated to what the final values should be from the original bounds.</li> <li>The bounds above the expanding view are * animated upwards while the bounds below the expanding view are animated downwards.</li> <li>The extra text is faded in as its contents become visible * throughout the animation process.</li> * * <br/> * <br/> * <p> * It is important to note that the listview is disabled during the animation because the scrolling behavior is unpredictable if the bounds of the items * within the listview are not constant during the scroll. * </p> * <br/> * * @param view * expanding view * @param position * item position in list * @param id * item id */ private void expandView(final View view, int position, long id) { // final ExpandableListItem item = (ExpandableListItem) nlv.getItemAtPosition(nlv.getPositionForView(view)); HydraListAdapter<ExpandableListItem> expandingAdapter = getExpandingAdapter(); final ExpandableListItem item = expandingAdapter.getDataProvider().get(position); ExpandingLayout expandingLayout = expandingAdapter.getExpandingHelper().getExpandedView(view, item); /* Store the original top and bottom bounds of all the cells. */ final int oldTop = view.getTop(); final int oldBottom = view.getBottom(); final HashMap<View, int[]> oldCoordinates = new HashMap<View, int[]>(); int childCount = nlv.getChildCount(); for (int i = 0; i < childCount; i++) { View v = nlv.getChildAt(i); ViewCompat.setHasTransientState(v, true); oldCoordinates.put(v, new int[] { v.getTop(), v.getBottom() }); } /* Update the layout so the extra content becomes visible. */ expandingLayout.setVisibility(View.VISIBLE); /* * Add an onPreDraw Listener to the listview. onPreDraw will get invoked after onLayout * and onMeasure have run but before anything has been drawn.
