recycleView实现item点击更改该item颜色，其它item颜色变回

项目中需要横向滚动效果，按照以前的思路，我会写一个ScrollView，里边加一个LinearLayout，在代码中动态加入控件，然后动态删除或者改变颜色，现在android有了新控件RecyclerView，可以方便的实现这样的功能，具体使用方法请参考这篇文章:Android 自定义RecyclerView 实现真正的Gallery效果 
主要问题在于，我点击一个item，改变颜色，点击其他项，改变颜色，上一次点击的变回原来的颜色，刚开始实现的方法是在控件上直接修改，发现滑动的时候，颜色会乱掉，所以在adapter里边加入一个list进行标记，根据标记改变控件颜色 
相应的adapter

public class AddDeviceAdapter extends RecyclerView.Adapter<AddDeviceAdapter.ViewHolder> /*implements View.OnClickListener*/{ private OnItemClickListener mOnItemClickListener = null; private LayoutInflater mInflater; private List mDatas; private AddDevice addDevice; private List isClicks;//控件是否被点击,默认为false，如果被点击，改变值，控件根据值改变自身颜色 public AddDeviceAdapter(Context context, List datas) { mInflater = LayoutInflater.from(context); mDatas = datas; isClicks = new ArrayList<>(); for(int i = 0;ifalse); } } public void setDatas(List datas) { mDatas = datas; L.e("AddDeviceAdapter's mDatas===" + new Gson().toJson(mDatas)); } public void setOnItemClickLitener(OnItemClickListener mOnItemClickListener) { this.mOnItemClickListener = mOnItemClickListener; } @Override public int getItemCount() { return mDatas.size(); } @Override public ViewHolder onCreateViewHolder(ViewGroup viewGroup, int i) { View view = mInflater.inflate(R.layout.item_add_device, viewGroup, false); ViewHolder viewHolder = new ViewHolder(view); viewHolder.viewSpace = view.findViewById(R.id.viewSpace); viewHolder.ivAddDevice = (ImageView) view.findViewById(R.id.ivAddDevice); viewHolder.tvAddDevice = (TextView) view.findViewById(R.id.tvAddDevice); //将创建的View注册点击事件 // view.setOnClickListener(this); return viewHolder; } @Override public void onBindViewHolder(final ViewHolder viewHolder, final int i) { addDevice = mDatas.get(i); viewHolder.ivAddDevice.setImageResource(addDevice.getResId()); viewHolder.tvAddDevice.setText(addDevice.getItemText()); //将数据保存在itemView的Tag中，以便点击时进行获取 viewHolder.itemView.setTag(viewHolder.tvAddDevice); if(isClicks.get(i)){ viewHolder.tvAddDevice.setTextColor(Color.parseColor("#00a0e9")); }else{ viewHolder.tvAddDevice.setTextColor(Color.parseColor("#ffffff")); } // if(addDevice.isFirst()) { // viewHolder.viewSpace.setVisibility(View.GONE); // } // 如果设置了回调，则设置点击事件 if (mOnItemClickListener != null) { viewHolder.itemView.setOnClickListener(new View.OnClickListener() { @Override public void onClick(View v) { for(int i = 0; i false); } isClicks.set(i,true); notifyDataSetChanged(); mOnItemClickListener.onItemClick(viewHolder.itemView,viewHolder.tvAddDevice, i); } }); } } /* @Override public void onClick(View v) { if (mOnItemClickListener != null) { //注意这里使用getTag方法获取数据 mOnItemClickListener.onItemClick(, textView,(int)v.getTag()); } }*/ public static class ViewHolder extends RecyclerView.ViewHolder { public ViewHolder(View arg0) { super(arg0); } View viewSpace; ImageView ivAddDevice; TextView tvAddDevice; } public interface OnItemClickListener { void onItemClick(View view, TextView textView,int position); } }
