/** * 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/>/*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. */ private void collapseView(final View view) { final ExpandableListItem viewObject = (ExpandableListItem) 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 invisible. */ view.setLayoutParams(new LayoutParams(LayoutParams.MATCH_PARENT, viewObject.getCollapsedHeight())); /* Add an onPreDraw listener. */ final ViewTreeObserver observer = 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 = getChildAt(0).getTop(); int firstVisiblePosition = getFirstVisiblePosition(); int deltaTop = currentTop - futureTop; int i; int childCount = getChildCount(); for (i = 0; i < childCount; i++) { View v = 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; } setSelectionFromTop(firstVisiblePosition, firstChildStartTop - deltaTop); requestLayout(); return false; } mShouldRemoveObserver = false; observer.removeOnPreDrawListener(this); int yTranslateTop = mTranslate[0]; int yTranslateBottom = mTranslate[1]; int index = indexOfChild(view); int childCount = getChildCount(); for (int i = 0; i < childCount; i++) { View v = 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 ? yTranslateBottom : -yTranslateTop; v.setTop(v.getTop() + delta); v.setBottom(v.getBottom() + delta); } } final View expandingLayout = view.findViewById(R.id.expanding_layout); /* * Animates all the cells present on the screen after the * collapse. */ ArrayList<Animator> animations = new ArrayList<Animator>(); for (int i = 0; i < childCount; i++) { View v = getChildAt(i); if (v != view) { float diff = i > index ? -yTranslateBottom : yTranslateTop; animations.add(getAnimation(v, diff, diff)); } } /* Adds animation for collapsing the cell that was clicked. */ animations.add(getAnimation(view, yTranslateTop, -yTranslateBottom)); /* Adds an animation for fading out the extra content. */ animations.add(ObjectAnimator.ofFloat(expandingLayout, View.ALPHA, 1, 0)); /* Disabled the ListView for the duration of the animation. */ setEnabled(false); setClickable(false); /* * Play all the animations created above together at the same * time. */ AnimatorSet s = new AnimatorSet(); s.playTogether(animations); s.addListener(new AnimatorListenerAdapter() { @Override public void onAnimationEnd(Animator animation) { expandingLayout.setVisibility(View.GONE); view.setLayoutParams( new LayoutParams(LayoutParams.MATCH_PARENT, LayoutParams.WRAP_CONTENT)); viewObject.setExpanded(false); setEnabled(true); setClickable(true); /* * Note that alpha must be set back to 1 in case this * view is reused by a cell that was expanded, but not * yet collapsed, so its state should persist in an * expanded state with the extra content visible. */ expandingLayout.setAlpha(1); } }); s.start(); return true; } }); }
