## EasyAdapter

## Introduction
A simplified and powerful version for openharmony [BaseItemProvider].

## Usage instructions
Ordinary use:
``` java
adapter = new EasyAdapter<User>(userList, ResourceTable.Layout_item) {
            protected void bind(@NotNull ViewHolder holder, @NotNull User user, int position) {
                holder.setText(ResourceTable.Id_tv_name, "name: " + user.getName());
                holder.setText(ResourceTable.Id_tv_age, "age: " + user.getAge());
            }
        };
        adapter.setOnItemClickListener(new MultiItemTypeAdapter.SimpleOnItemClickListener() {
            public void onItemClick(@NotNull Component view, @NotNull ViewHolder holder, int position) {
                super.onItemClick(view, holder, position);
                ToastDialog toast = new ToastDialog(MainAbility.this);
                toast.setText("position - " + position);
                toast.show();
                userList.remove(position);
                adapter.notifyDataSetItemRemoved(position + adapter.getHeadersCount());
            }
        });
        adapter.addHeaderView(createView("Header - 1，点我在头部添加一条数据", false));
        adapter.addHeaderView(createView("Header - 2，点我在头部添加一条数据", false));
        adapter.addFootView(createView("Footer - 1，点我在末尾添加一条数据", true));
        adapter.addFootView(createView("Footer - 2，点我在末尾添加一条数据", true));

        listContainer.setItemProvider(adapter);
```

Multiple entries:
``` java
multiItemTypeAdapter = new MultiItemTypeAdapter<>(userList);
        multiItemTypeAdapter.addItemDelegate(new OneDelegate());
        multiItemTypeAdapter.addItemDelegate(new TwoDelegate());
        multiItemTypeAdapter.addHeaderView(createView("Multi Header view1111", false));
        multiItemTypeAdapter.addHeaderView(createView("Multi Header view22222", false));
        multiItemTypeAdapter.addFootView(createView("Multi Footer view", false));
        multiItemTypeAdapter.setOnItemClickListener(new MultiItemTypeAdapter.OnItemClickListener() {

            @Override
            public void onItemClick(@NotNull Component view, @NotNull ViewHolder holder, int position) {
                ToastDialog toast = new ToastDialog(MainAbility.this);
                toast.setText("position: " + position);
                toast.show();
            }

            @Override
            public boolean onItemLongClick(@NotNull Component view, @NotNull ViewHolder holder, int position) {
                return false;
            }
        });
        listContainer.setItemProvider(multiItemTypeAdapter);

public class OneDelegate implements ItemDelegate<User> {

        @Override
        public int getLayoutId() {
            return ResourceTable.Layout_simple_list_item;
        }

        @Override
        public boolean isThisType(@NotNull User item, int position) {
            return position % 2 != 0;
        }

        @Override
        public void bind(@NotNull ViewHolder holder, @NotNull User user, int position) {
            holder.setText(ResourceTable.Id_text1, "name: " + user.getName() + " - " + position);
        }
    }

    public class TwoDelegate implements ItemDelegate<User> {

        @Override
        public int getLayoutId() {
            return ResourceTable.Layout_simple_list_item;
        }

        @Override
        public boolean isThisType(@NotNull User item, int position) {
            return position % 2 == 0;
        }

        @Override
        public void bind(@NotNull ViewHolder holder, @NotNull User user, int position) {
            holder.setText(ResourceTable.Id_text1, "age: " + user.getAge());
            ShapeElement element = new ShapeElement();
            element.setRgbColor(RgbColor.fromArgbInt(Color.RED.getValue()));
            holder.getView(ResourceTable.Id_text1).setBackground(element);
        }
    }
```
