RecyclerView-实现多种item布局

多种布局主要重写Adapter中的 getItemViewType 方法:

    @Override
    public int getItemViewType(int position) {
        return mDatas.get(position).getViewId();
    }

然后再 onCreateViewHolder 中根据 viewType 使用不用的 LayoutId 创建不同的 ViewHolder 并返回（此处的viewType既LayoutId，根据需要自己改变）：

    //此处viewType既layoutId
    @Override
    public CommonViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
        return CommonViewHolder.get(mContext,null,parent,viewType,-1);
    }

接下来在 onBindViewHolder 中根据不同的布局加载不同的数据：

    @Override
    public void onBindViewHolder(CommonViewHolder holder, final int position) {
        if(mItemClickListener != null){
        }
        holder.itemView.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View view) {
                if(mItemClickListener != null && view != null && recyclerView != null){
                    int pos = recyclerView.getChildAdapterPosition(view);
                    if(mDatas.get(pos).getViewId() == R.layout.item_search_two){
                        mItemClickListener.onItemThreeClick(recyclerView,view,position);
                    }else if (mDatas.get(pos).getViewId() == R.layout.item_search_three){
                        mItemClickListener.onItemTwoClick(recyclerView,view,position);
                    }
                }
            }
        });
        convert(holder,mDatas.get(position));
    }

    @Override
    public void convert(CommonViewHolder holder, AudioBean audioBean) {
        Bitmap bitmap;
        BitmapFactory.Options op = new BitmapFactory.Options();
        op.inSampleSize = 6;
        switch (audioBean.getViewId()){
            case R.layout.item_search_three:
                holder.setText(R.id.tv_title,audioBean.getTitle());
                holder.setText(R.id.tv_describe,audioBean.getArtist());
                bitmap = BitmapFactory.decodeResource(mContext.getResources(),R.drawable.taylor_swift,op);
                BitmapDrawable bd = new BitmapDrawable(mContext.getResources(),bitmap);
                holder.setImageDrawable(R.id.iv_image,bd);
                break;
            case R.layout.item_search_two:
                holder.setText(R.id.tv_title,audioBean.getTitle());
                holder.setText(R.id.tv_describe,audioBean.getArtist());
                bitmap = BitmapFactory.decodeResource(mContext.getResources(),R.drawable.taylor_swift,op);
                holder.setImageBitmap(R.id.iv_image,bitmap);
                break;
        }
    }

如果遇到图片加载不出的情况，可以试试：

RecyclerView.RecycledViewPool pool =recyclerView.getRecycledViewPool();
pool.setMaxRecycledViews(0,10);
recyclerView.setRecycledViewPool(pool);
