RecyclerView 横向列表 及 adapter 打造 item监听 改变元素属性

public class RecyclerHorizontalAdapter extends RecyclerView.Adapter<RecyclerHorizontalAdapter.MyViewHolder > implements View.OnClickListener{

private Context mContext;
private List<CarModelType> items;
private int checkPosition;

public OnItemClickListener onItemClickListener;

this.mContext = context;
this.items = items;
}

public int getCheckPosition() {

}

public void setCheckPosition(int checkPosition) {
this.checkPosition = checkPosition;
}

@Override
public MyViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
//负责创建视图  
View view = LayoutInflater.from(mContext).inflate(R.layout.item_make_year, null);
//将全局的监听传递给holder
MyViewHolder holder = new MyViewHolder(view);
return holder;
}

@Override
public void onClick(View view) {
int position = (int) view.getTag();
if(null != onItemClickListener){
onItemClickListener.onItemClick(position, view);
}
}

@Override

holder.SetContent(item);

holder.itemView.setTag(position);

if(position == getCheckPosition()){

holder.cutLine.setBackgroundColor(mContext.getResources().getColor(R.color.deep_sky_blue));
}else{
holder.yearName.setTextColor(mContext.getResources().getColor(R.color.montana));

}

private void initView() {

//拿适配器调用适配器内部自定义好的setCheckPosition方法（参数写点击事件的参数的position）
recyclerHorizontalAdapter.setCheckPosition(position);
//不要忘记刷新适配器
recyclerHorizontalAdapter.notifyDataSetChanged();
