/** * 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/>// w w w.j a v a2s . 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. */ private void expandView(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 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.
