Overview

SlideAndDragListView (SDLV) is an extension of the Android ListView that enables slide and drag-and-drop reordering of list items.

 Some key features are:

  2. Intuitive and smooth scrolling while dragging or sliding.
  3. Support onItemClick and onItemLongClick listener.
  4. Public callback methods.
  5. Two side of item can slide.
  6. so on...

SlideAndDragListView is useful for all kinds of prioritized lists: favorites, playlists, checklists, etc. Would love to hear about your use case or app by email. I hope you find it useful; and please, help me improve the thing!

Widget Usage

Menu Item Click & Slide Directions

Step 1

  • Add SlideAndDragListView in layout xml
<com.yydcdut.sdlv.SlideAndDragListView
        android:layout_width="fill_parent"
        android:layout_height="fill_parent">
</com.yydcdut.sdlv.SlideAndDragListView>

Step 2

  • Create a Menu and add MenuItem
Menu menu = new Menu(true, true, 0);//the second parameter is whether can slide over
menu.addItem(new MenuItem.Builder().setWidth(90)//set Width
                .setBackground(new ColorDrawable(Color.RED))// set background
                .setText("One")//set text string
                .setTextColor(Color.GRAY)//set text color
                .setTextSize(20)//set text size
                .build());
menu.addItem(new MenuItem.Builder().setWidth(120)
                .setBackground(new ColorDrawable(Color.BLACK))
                .setDirection(MenuItem.DIRECTION_RIGHT)//set direction (default DIRECTION_LEFT)
                .setIcon(getResources().getDrawable(R.drawable.ic_launcher))// set icon
                .build());
//set in sdlv
slideAndDragListView.setMenu(menu);

The class Menu, the construct function Menu(bool wannaTransparentWhileDragging, boolean wannaOver, int menuViewType), the first parameter means whether set background transparent while dragging, the second parameter means whether can slide over.

If it’s true:

If it’s false:

The third parameter stands for view type, the value of int getItemViewType(int ) in BaseAdapter.

Step 3

  • Implement menu item click listener
slideAndDragListView.setOnSlideListener(new SlideAndDragListView.OnSlideListener() {
            @Override
            public void onSlideOpen(View view, View parentView, int position, int direction) {

            }

            @Override
            public void onSlideClose(View view, View parentView, int position, int direction) {

            }
        });
slideAndDragListView.setOnMenuItemClickListener(new SlideAndDragListView.OnMenuItemClickListener() {
            @Override
            public int onMenuItemClick(View v, int itemPosition, int buttonPosition, int direction) {
                switch (direction) {
                    case MenuItem.DIRECTION_LEFT:
                        switch (buttonPosition) {
                            case 0://One
                                return Menu.ITEM_SCROLL_BACK;
                        }
                        break;
                    case MenuItem.DIRECTION_RIGHT:
                        switch (buttonPosition) {
                            case 0://icon
                                return Menu.ITEM_DELETE_FROM_BOTTOM_TO_TOP;
                        }
                        break;
                    default :
                        return Menu.ITEM_NOTHING;
                }
            }
        });

Have to set OnSlideListener!!!!!!

Menu.ITEM_NOTHING:

Menu.ITEM_SCROLL_BACK:

Menu.ITEM_DELETE_FROM_BOTTOM_TO_TOP:

Create Different Menu

  • Use the ViewType of adapter
private BaseAdapter mAdapter = new BaseAdapter() {
        // .......
        @Override
        public int getItemViewType(int position) {
            return position % 2;//current menu type
        }

        @Override
        public int getViewTypeCount() {
            return 2;//menu type count
        }
  		// ......
}
  • Create different menus depending on the view type
List<Menu> menuList = new ArrayList<>(2);
Menu menu0 = new Menu(new ColorDrawable(Color.WHITE), true, 0);
menu0.addItem(new MenuItem.Builder().setWidth(90)//set Width
                .setBackground(new ColorDrawable(Color.RED))// set background
                .setText("One")//set text string
                .setTextColor(Color.GRAY)//set text color
                .setTextSize(20)//set text color
                .build());
menu0.addItem(new MenuItem.Builder().setWidth(120)
                .setBackground(new ColorDrawable(Color.BLACK))
                .setDirection(MenuItem.DIRECTION_RIGHT)//set direction (default DIRECTION_LEFT)
                .setIcon(getResources().getDrawable(R.drawable.ic_launcher))// set icon
                .build());
Menu menu1 = new Menu(new ColorDrawable(Color.YELLOW), false, 1);
menu1.addItem(new MenuItem.Builder().setWidth(60)
                .setBackground(new ColorDrawable(Color.RED))
                .setText("Two")
                .setTextColor(Color.GRAY)
                .setTextSize(25)
                .build());
menu1.addItem(new MenuItem.Builder().setWidth(70)
                .setBackground(new ColorDrawable(Color.BLUE))
                .setText("Three")
                .setDirection(MenuItem.DIRECTION_RIGHT)
                .setTextColor(Color.BLACK)
                .setTextSize(20)
                .build());
menuList.add(menu0);
menuList.add(menu1);
listView.setMenu(menuList)
