Widget Usage

Menu Item Click & Slide Directions

Step 1

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

Step 2

  • Create a Menu and add MenuItem
Menu menu = new Menu(true, 0);//the first 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
                .setIcon(getResources().getDrawable(R.drawable.ic_launcher))// set icon
                .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(boolean slideOver, int menuViewType), the first parameter means whether can slide over.

If it’s true:

If it’s false:

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

Step 3

  • Implement menu item click listener
slideAndDragListView.setOnMenuItemClickListener(new 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;
        }
        return Menu.ITEM_NOTHING;
    }
});

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)

Drag

ApplicationInfo mDraggedEntity;
List<ApplicationInfo> mDataList;

// ...init...

slideAndDragListView.setOnDragDropListener(new OnDragDropListener() {
    @Override
    public void onDragViewStart(int beginPosition) {
        mDraggedEntity = mDataList.get(beginPosition);
    }

    @Override
    public void onDragDropViewMoved(int fromPosition, int toPosition) {
		ApplicationInfo applicationInfo = mDataList.remove(fromPosition);
      	mDataList.add(toPosition, applicationInfo);
    }

    @Override
    public void onDragViewDown(int finalPosition) {
		mDataList.set(finalPosition, mDraggedEntity);
    }
});

public void onDragViewStart(int position).The parameter position is the position in ListView where dragged from.

public void onDragDropViewMoved(int fromPosition, int toPosition) .The parameters fromPosition and toPosition are the positions in ListView where dragged from and dragged to.

public void onDragViewDown(int position) . The parameter position is the position in ListView where dropped down.
