CanAdapter

一个继承BaseAdapter和RecyclerView.Adapter的库，将Adapter封装成相同的方法，方便使用。

##添加依赖

compile 'com.github.canyinghao:CanAdapter:5.0.3'

使用方式

1. CanAdapter介绍
ListView使用CanAdapter，RecyclerView使用CanRVAdapter，主要重写它们的三个方法，构造函数、setView、setItemListener这三个。setItemListener的目的是让事件可以在activity中处理，方便adapter的重用。使用adapter.setOnItemListener就可以在activity中处理事件，总共5个事件，onItemChildClick、onItemChildLongClick、onItemChildCheckedChanged、onRVItemClick、onRVItemLongClick。

2. ListView 使用CanAdapter

public class ListViewFragment extends Fragment {
    ListView listView;


    @Nullable
    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {

        listView = new ListView(getContext());


        final CanAdapter adapter = new CanAdapter<MainBean>(getContext(), R.layout.item_main) {


            @Override
            protected void setView(CanHolderHelper helper, int position, MainBean model) {
                helper.setText(R.id.tv_title, model.title);
                helper.setText(R.id.tv_content, model.content);

            }

            @Override
            protected void setItemListener(CanHolderHelper helper) {

                helper.setItemChildClickListener(R.id.tv_title);
                helper.setItemChildClickListener(R.id.tv_content);

            }
        };

        listView.setAdapter(adapter);


        adapter.setOnItemListener(new CanOnItemListener() {

            public void onItemChildClick(View view, int position) {

                MainBean bean = (MainBean) adapter.getItem(position);
                switch (view.getId()) {


                    case R.id.tv_title:

                        App.getInstance().show(bean.title);
                        break;

                    case R.id.tv_content:
                        App.getInstance().show(bean.content);
                        break;
                }


            }

        });


        adapter.setList(MainBean.getList());


        return listView;
    }


}

3. RecyclerView 使用CanRVAdapter

public class RVListFragment extends Fragment {

    RecyclerView recyclerView;


    @Nullable
    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {

        recyclerView = new RecyclerView(getContext());

        LinearLayoutManager mLayoutManager = new LinearLayoutManager(getContext(), LinearLayoutManager.VERTICAL, false);
        recyclerView.setLayoutManager(mLayoutManager);

        final CanRVAdapter adapter = new CanRVAdapter<MainBean>(recyclerView, R.layout.item_main) {


            @Override
            protected void setView(CanHolderHelper helper, int position, MainBean model) {
                helper.setText(R.id.tv_title, model.title);
                helper.setText(R.id.tv_content, model.content);

            }

            @Override
            protected void setItemListener(CanHolderHelper helper) {

                helper.setItemChildClickListener(R.id.tv_title);
                helper.setItemChildClickListener(R.id.tv_content);

            }
        };

        recyclerView.setAdapter(adapter);


        adapter.setOnItemListener(new CanOnItemListener() {

            public void onItemChildClick(View view, int position) {

                MainBean bean = (MainBean) adapter.getItem(position);
                switch (view.getId()) {


                    case R.id.tv_title:

                        App.getInstance().show(bean.title);
                        break;

                    case R.id.tv_content:
                        App.getInstance().show(bean.content);
                        break;
                }


            }

        });


        adapter.setList(MainBean.getList());


        return recyclerView;
    }


}

4. 新添加可供RecyclerView使用的CanErvAdapter
CanErvAdapter有分组功能，可展开或收起分组，可只允许展开一个，可展开全部不允许收起。LayoutManager提供子项每行的个数，LinearLayoutManager每行一个，GridLayoutManager设置的spanCount为多少就是多少。
限制以及问题：group可使用的区域的宽度与子项每一项的宽度相同。也就是说，当spanCount为3时，group项的宽度只有屏幕宽度的三分之一。这需要特别注意。

CanRVHFAdapter有分组功能，可以添加头部足部。
