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.</li> <li>On the second predraw pass, all the items are first returned to their original location (before the first layout).</li> <li>The * collapsing view's bounds are animated to what the final values should be.</li> <li>The bounds above the collapsing view are animated downwards while the * bounds below the collapsing view are animated upwards.</li> <li>The extra text is faded out as its contents become visible throughout the animation * process.</li> * * @param view * collapsing view * @param position * item position in list * @param id * item id */ private void collapseView(final View view, int position, long id) { final ExpandableListItem item = (ExpandableListItem) nlv.getItemAtPosition(nlv.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 = 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 invisible. */ view.setLayoutParams( new AbsListView.LayoutParams(AbsListView.LayoutParams.MATCH_PARENT, item.getCollapsedHeight())); /* Add an onPreDraw listener. */ final ViewTreeObserver observer = nlv.getViewTreeObserver(); observer.addOnPreDrawListener(new ViewTreeObserver.OnPreDrawListener() { @Override public boolean onPreDraw() { if (!mShouldRemoveObserver) { /* * Same as for expandingView, the parameters for setSelectionFromTop must * be determined such that the necessary cells of the ListView are rendered * and added to it. */ mShouldRemoveObserver = true; int newTop = view.getTop(); int newBottom = view.getBottom(); int newHeight = newBottom - newTop; int oldHeight = oldBottom - oldTop; int deltaHeight = oldHeight - newHeight; mTranslate = getTopAndBottomTranslations(oldTop, oldBottom, deltaHeight, false); int currentTop = view.getTop(); int futureTop = oldTop + mTranslate[0]; int firstChildStartTop = nlv.getChildAt(0).getTop(); int firstVisiblePosition = nlv.getFirstVisiblePosition(); int deltaTop = currentTop - futureTop; int i; int childCount = nlv.getChildCount(); for (i = 0; i < childCount; i++) { View v = nlv.getChildAt(i); int height = v.getBottom() - Math.max(0, v.getTop()); if (deltaTop - height > 0) { firstVisiblePosition++; deltaTop -= height; } else { break; } } if (i > 0) { firstChildStartTop = 0; } nlv.setSelectionFromTop(firstVisiblePosition, firstChildStartTop - deltaTop); nlv.requestLayout(); return false; } mShouldRemoveObserver = false; observer.removeOnPreDrawListener(this); int yTranslateTop = mTranslate[0]; int yTranslateBottom = mTranslate[1]; int index = nlv.indexOfChild(view); int childCount = nlv.getChildCount(); for (int i = 0; i < childCount; i++) { View v = nlv.getChildAt(i); int[] old = oldCoordinates.get(v); if (old != null) { /* * If the cell was present in the ListView before the collapse and * after the collapse then the bounds are reset to their old values. */ v.setTop(old[0]); v.setBottom(old[1]); ViewCompat.setHasTransientState(v, false); } else { /* * If the cell is present in the ListView after the collapse but * not before the collapse then the bounds are calculated using * the bottom and top translation of the collapsing cell. */ int delta = i > index ?
