快速入门

创建Adapter

public class ChatAdapter extends BaseRecyclerAdapter<Message> {

    public ChatAdapter(Context context, IMutlipleItem<Message> items, Collection<Message> datas) {
        super(context,items,datas);
    }

    @Override
    public void bindView(BaseRecyclerHolder holder, Message msg, int position) {
        if(holder.layoutId==R.layout.item_text){
            holder.setText(R.id.tv_recent_name,msg==null?"未知":msg.getContent()+","+msg.getType());
        }else if(holder.layoutId==R.layout.item_voice){
            holder.setText(R.id.tv_recent_name,msg==null?"未知":msg.getContent()+","+msg.getType());
        }else{
            holder.setText(R.id.tv_recent_name,msg==null?"未知":msg.getContent()+","+msg.getType());
        }
    }
}

支持自定义item布局

private final int TYPE_TXT=0;
private final int TYPE_VOICE=1;
private final int TYPE_OTHER=2;

IMutlipleItem<Message> mutlipleItem = new IMutlipleItem<Message>() {

    @Override
    public int getItemViewType(int postion, Message msg) {
        if(msg.getType().equals("txt")){
            return TYPE_TXT;
        }else if(msg.getType().equals("voice")){
            return TYPE_VOICE;
        }else{
            return TYPE_OTHER;
        }
    }

    @Override
    public int getItemLayoutId(int viewtype) {
        if(viewtype==TYPE_TXT){
            return R.layout.item_text;
        }else if(viewtype==TYPE_VOICE){
            return R.layout.item_voice;
        }else{
            return R.layout.item_other;
        }
    }

    @Override
    public int getItemCount(List<Message> list) {
        return list.size();
    }
};

adapter = new ChatAdapter(this,mutlipleItem,null);
rc_view.setAdapter(adapter);

支持添加点击、长按事件

adapter.setOnRecyclerViewListener(new OnRecyclerViewListener() {
        @Override
        public void onItemClick(int position) {
            Log.i("smile", "点击的是：" + position);
        }

        @Override
        public boolean onItemLongClick(final int position) {
            Log.i("smile", "长按的是：" + position);
            return true;
        }
    });

设置头部View

IMutlipleItem<Contact> mutlipleItem = new IMutlipleItem<Contact>() {

    @Override
    public int getItemViewType(int postion, Contact friend) {
        if(postion==0){//新朋友布局
            return 0;
        }else if(postion==1){//群聊布局
            return 1;
        }else{//联系人的list
            return 2;
        }
    }

    @Override
    public int getItemLayoutId(int viewtype) {
        if(viewtype==0){
            return R.layout.header_new_friend;这是一个头部view
        }else if(viewtype==1){
            return R.layout.header_group;//这是一个头部view
        }else{
            return R.layout.item_contact;
        }
    }

    @Override
    public int getItemCount(List<Contact> list) {
        return list.size()+2;//增加两个自定义的头部布局
    }
};
