RecyclerView的多种使用方式

分享

介绍:

在AdapterView和RecyclerView中通用的Adapter和ViewHolder,使AdapterView和RecyclerView适配器的使用方式基本一致。
使用非常简单,这里展示一下ListView和RecyclerView实现qq聊天界面的适配器
public class ListChatAdapter extends BGAAdapterViewAdapter<ChatModel> {

    public ListChatAdapter(Context context) {
        super(context, R.layout.item_chat);
    }

    /**
     * 为item的孩子节点设置监听器,并不是每一个数据列表都要为item的子控件添加事件监听器,所以在父类中采用了空实现,需要设置事件监听器时重写该方法即可
     *
     * @param viewHolderHelper
     */
    @Override
    protected void setItemChildListener(BGAViewHolderHelper viewHolderHelper) {
    }

    @Override
    public void fillData(BGAViewHolderHelper viewHolderHelper, int position, ChatModel model) {
        if (model.mUserType == ChatModel.UserType.From) {
            viewHolderHelper.setVisibility(R.id.rl_item_chat_to, View.GONE);
            viewHolderHelper.setVisibility(R.id.rl_item_chat_from, View.VISIBLE);
            String htmlMsg = String.format(mContext.getString(R.string.color_msg_from), model.mMsg);
            viewHolderHelper.setHtml(R.id.tv_item_chat_from_msg, htmlMsg);
        } else {
            viewHolderHelper.setVisibility(R.id.rl_item_chat_from, View.GONE);
            viewHolderHelper.setVisibility(R.id.rl_item_chat_to, View.VISIBLE);
            String htmlMsg = String.format(mContext.getString(R.string.color_msg_to), model.mMsg);
            viewHolderHelper.setHtml(R.id.tv_item_chat_to_msg, htmlMsg);
        }
    }

}

RecyclerView实现qq聊天界面的适配器

public class RecyclerChatAdapter extends BGARecyclerViewAdapter<ChatModel> {
    public RecyclerChatAdapter(RecyclerView recyclerView) {
        super(recyclerView, R.layout.item_chat);
    }

    /**
     * 为item的孩子节点设置监听器,并不是每一个数据列表都要为item的子控件添加事件监听器,所以在父类中采用了空实现,需要设置事件监听器时重写该方法即可
     *
     * @param viewHolderHelper
     */
    @Override
    public void setItemChildListener(BGAViewHolderHelper viewHolderHelper) {
    }

    @Override
    public void fillData(BGAViewHolderHelper viewHolderHelper, int position, ChatModel model) {
        if (model.mUserType == ChatModel.UserType.From) {
            viewHolderHelper.setVisibility(R.id.rl_item_chat_to, View.GONE);
            viewHolderHelper.setVisibility(R.id.rl_item_chat_from, View.VISIBLE);
            String htmlMsg = String.format(mContext.getString(R.string.color_msg_from), model.mMsg);
            viewHolderHelper.setHtml(R.id.tv_item_chat_from_msg, htmlMsg);
        } else {
            viewHolderHelper.setVisibility(R.id.rl_item_chat_from, View.GONE);
            viewHolderHelper.setVisibility(R.id.rl_item_chat_to, View.VISIBLE);
            String htmlMsg = String.format(mContext.getString(R.string.color_msg_to), model.mMsg);
            viewHolderHelper.setHtml(R.id.tv_item_chat_to_msg, htmlMsg);
        }
    }

}

运行效果:
