Implementation

Usage

Start checking out DemoActivity.java. Snippet:

/*Generate some data. 5 parents. Each parent has 5 childelements.*/
for(int i = 1; i < 6; i++){
      List<Child> children = new ArrayList<>();
      for(int j = 1; j < 6; j++)
          children.add(new Child("Child " + j + " from Parent " + i));
      parentList.add(new Parent("Parent " + i, children));
}

/*Setup the recyclerview with the generated data.*/
ExpRecyclerView expRecyclerView = new ExpRecyclerView(
      this,
      (RecyclerView) findViewById(R.id.exp_view),
      (TextView) findViewById(R.id.empty_view), //(optional param) if no items are in the list show a TextView "List is empty"
      parentList
);

/*Add data dynamically*/
List<Child> addedChildren = new ArrayList<>();
addedChildren.add(new Child("Dynamically added child 1"));
Parent addedParent = new Parent("Dynamically added parent", addedChildren);
expRecyclerView.addParent(addedParent);

Child addedChild = new Child("Dynamically added child 2");
expRecyclerView.addChild(addedChild);

Enable or disable Drag & Drop and Swipe dynamically:

expRecyclerView.enableParentsDrag();
expRecyclerView.enableChildrenDrag();
expRecyclerView.enableParentsSwipe();
expRecyclerView.enableChildrenSwipe();
expRecyclerView.disableParentsDrag();
expRecyclerView.disableChildrenDrag();
expRecyclerView.disableParentsSwipe();
expRecyclerView.disableChildrenSwipe();

Notes

If you need custom rules for adding, reordering and dismissing items modify ExpRecyclerView.class's addParent, addChild, ... methods.
