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!
compile 'com.yydcdut:sdlv:0.7.6'- Add SlideAndDragListView in layout xml
<com.yydcdut.sdlv.SlideAndDragListView
android:layout_width="match_parent"
android:layout_height="match_parent">
</com.yydcdut.sdlv.SlideAndDragListView>- 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.
- 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:
- 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

.setTextSize(20)//set text color
.build());
menu0.addItem(new MenuItem.Builder().setWidth(120)
