2.Usage

工程依赖 build.gradle

(1).project

allprojects {

		maven { url 'https://jitpack.io' }
	}
}

(2).app

listview及gridview通用adapter

dependencies {
        implementation 'com.github.wyba.MyBaseAdapter:library:V1.5.0'
}

recyclerview通用adapter如下

dependencies {
        implementation 'com.github.wyba.MyBaseAdapter:rv-library:V1.5.0'
}

Use it

(1).普通的ListView

CommonAdapter<String> commonAdapter = new CommonAdapter<String>(this, R.layout.item_menu, mDatas) {
    @Override
    protected void convert(ViewHolder viewHolder, String item, int position) {
        viewHolder.setText(R.id.lv_menu_item_tv_title, item);
    }

    @Override
    public void onViewHolderCreated(ViewHolder holder, View itemView) {
        super.onViewHolderCreated(holder, itemView);
    }
};

lv_menu.setAdapter(commonAdapter);

(2).多类型Item ListView

public class ChatAdapter extends MultiItemTypeAdapter<ChatMessage> {

    public ChatAdapter(Context context, List<ChatMessage> datas) {
        super(context, datas);
        addItemViewDelegate(new MsgSendItemDelagate());
        addItemViewDelegate(new MsgComingItemDelagate());
    }

}

(3).普通的RecycleView

        mRecyclerView = (RecyclerView) findViewById(R.id.id_recyclerview);
//        mRecyclerView.setHasFixedSize(true);
//        mRecyclerView.setLayoutManager(new LinearLayoutManager(this));
        mRecyclerView.setLayoutManager(new GridLayoutManager(this, 2));
//        mRecyclerView.setLayoutManager(new StaggeredGridLayoutManager(2, StaggeredGridLayoutManager.VERTICAL));
        mRecyclerView.addItemDecoration(new DividerItemDecoration(this, DividerItemDecoration.VERTICAL_LIST));

        mAdapter = new CommonAdapter<String>(this, R.layout.item_menu, mDatas) {
            @Override
            protected void convert(ViewHolder holder, String s, int position) {
                holder.setText(R.id.lv_menu_item_tv_title, s + " : " + holder.getAdapterPosition() + " , " + holder.getLayoutPosition());
            }
        };

        initHeaderAndFooter();

//        initEmptyView();

        mLoadMoreWrapper = new LoadMoreWrapper(mHeaderAndFooterWrapper);
        mLoadMoreWrapper.setLoadMoreView(R.layout.default_loading);
        mLoadMoreWrapper.setOnLoadMoreListener(new LoadMoreWrapper.OnLoadMoreListener() {
            @Override
            public void onLoadMoreRequested() {
                new Handler().postDelayed(new Runnable() {
                    @Override
                    public void run() {
                        for (int i = 0; i < 10; i++) {
                            mDatas.add("Add:" + i);
                        }
                        mLoadMoreWrapper.notifyDataSetChanged();

                    }
                }, 3000);
            }
        });

        mRecyclerView.setAdapter(mLoadMoreWrapper);
        mAdapter.setOnItemClickListener(new CommonAdapter.OnItemClickListener() {
            @Override
            public void onItemClick(View view, RecyclerView.ViewHolder holder, int position) {
                Toast.makeText(RecyclerViewActivity.this, "pos = " + position, Toast.LENGTH_SHORT).show();
                mAdapter.notifyItemRemoved(position);
            }

            @Override
            public boolean onItemLongClick(View view, RecyclerView.ViewHolder holder, int position) {
                return false;
            }
        });

(4).多类型Item RecycleView

    public class ChatAdapterForRv extends MultiItemTypeAdapter<ChatMessage> {
    
        public ChatAdapterForRv(Context context, List<ChatMessage> datas) {
            super(context, datas);
            addItemViewDelegate(new MsgSendItemDelagate());
            addItemViewDelegate(new MsgComingItemDelagate());
        }
    
    }
    
    
  ChatAdapterForRv adapter = new ChatAdapterForRv(this, mDatas);

        mLoadMoreWrapper = new LoadMoreWrapper(adapter);

        mLoadMoreWrapper.setLoadMoreView(LayoutInflater.from(this).inflate(R.layout.default_loading, mRecyclerView, false));

        mLoadMoreWrapper.setOnLoadMoreListener(new LoadMoreWrapper.OnLoadMoreListener() {
            @Override
            public void onLoadMoreRequested() {
                new Handler().postDelayed(new Runnable() {
                    @Override
                    public void run() {
                        boolean coming = Math.random() > 0.5;
                        ChatMessage msg = null;
                        msg = new ChatMessage(coming ? R.drawable.renma : R.drawable.xiaohei, coming ? "人马" : "xiaohei", "where are you " + mDatas.size(),
                                null, coming);
                        mDatas.add(msg);
                        mLoadMoreWrapper.notifyDataSetChanged();

                    }
                }, 3000);
            }
        });

        adapter.setOnItemClickListener(new CommonAdapter.OnItemClickListener() {
            @Override
            public void onItemClick(View view, RecyclerView.ViewHolder holder, int position) {
                Toast.makeText(MultiItemRvActivity.this, "Click:" + position, Toast.LENGTH_SHORT).show();
            }

            @Override
            public boolean onItemLongClick(View view, RecyclerView.ViewHolder holder, int position) {
                Toast.makeText(MultiItemRvActivity.this, "LongClick:" + position, Toast.LENGTH_SHORT).show();
                return false;
            }
        });
        mRecyclerView.setAdapter(mLoadMoreWrapper);
