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
Menuand addMenuItem
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)- See the demo
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.
Other Listeners
Item Slide Listener
slideAndDragListView.setOnSlideListener(new OnSlideListener() {
@Override
public void onSlideOpen(View view, View parentView, int position, int direction) {
}
@Override

}
});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.

Item Delete Listener
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.
