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(new ColorDrawable(Color.WHITE), 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(Drawable itemBackGroundDrawable, boolean wannaOver, int menuViewType), 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)
