# 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:

1. Clean drag and drop.
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!

# Binaries

## Gradle

``` groovy
compile 'com.yydcdut:sdlv:0.7.6'
```

## Jar

[DOWNLOAD](https://github.com/yydcdut/SlideAndDragListView/blob/master/jar/sdlv.jar?raw=true)

# Widget Usage

## Menu Item Click & Slide Directions

### Step 1

- Add SlideAndDragListView in layout xml

``` 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`

``` java
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

``` java
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

``` java
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

``` java
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)
```

* See the demo

## Drag

``` java
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.

## Other Listeners

### Item Slide Listener

``` java
slideAndDragListView.setOnSlideListener(new 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) {

}
});
```

`public void onSlideOpen(View view, View parentView, int position, int direction)`. The parameter `view` is the ListView item that is slide open, `parentView` here is SDLV, `position` is the position of the view in the list, and the parameter `direction` is the item slided direction.

`public void onSlideClose(View view, View parentView, int position, int direction)`. The parameter `view` is the ListView item that is slide close,`parentView` here is SDLV, `position` is the position of the view in the list, and the parameter `direction` is the item slided direction.

### Item Delete Listener

``` java
slideAndDragListView.setOnItemDeleteListener(new OnItemDeleteListener() {
    @Override
    public void onItemDeleteAnimationFinished(View view, int position) {
        
    }
});
```

`public void onItemDeleteAnimationFinished(View view, int position)` will invoked after `int onMenuItemClick(View v, int itemPosition, int buttonPosition, int direction)` return `Menu.ITEM_DELETE_FROM_BOTTOM_TO_TOP`.

### Item Menu Scroll Back Listener

```java
slideAndDragListView.setOnItemScrollBackListener(new OnItemScrollBackListener() {
    @Override
    public void onScrollBackAnimationFinished(View view, int position) {

}
});
```

`public void onScrollBackAnimationFinished(View view, int position)` will invoked after `int onMenuItemClick(View v, int itemPosition, int buttonPosition, int direction)` return `Menu.ITEM_SCROLL_BACK`.
