需求：类似医院或者商场，大屏幕无限轮播item (广告词/广告图…)，供大家参考，具体内容如下

代码如下

/** * Created by Xia_焱 on 2017/8/20. */public class AutoPollRecyclerView extends RecyclerView { private static final long TIME_AUTO_POLL = 32; AutoPollTask autoPollTask; private boolean running; //标示是否正在自动轮询 private boolean canRun;//标示是否可以自动轮询,可在不需要的是否置false public AutoPollRecyclerView(Context context, @Nullable AttributeSet attrs) {  super(context, attrs);  autoPollTask = new AutoPollTask(this); } static class AutoPollTask implements Runnable {  private final WeakReference mReference;  //使用弱引用持有外部类引用->防止内存泄漏  public AutoPollTask(AutoPollRecyclerView reference) {   this.mReference = new WeakReference(reference);  }  @Override  public void run() {   AutoPollRecyclerView recyclerView = mReference.get();   if (recyclerView != null && recyclerView.running &&recyclerView.canRun) {    recyclerView.scrollBy(2, 2);    recyclerView.postDelayed(recyclerView.autoPollTask,recyclerView.TIME_AUTO_POLL);   }  } } //开启:如果正在运行,先停止->再开启 public void start() {  if (running)   stop();  canRun = true;  running = true;  postDelayed(autoPollTask,TIME_AUTO_POLL); } public void stop(){  running = false;  removeCallbacks(autoPollTask); } @Override public boolean onTouchEvent(MotionEvent e) {  switch (e.getAction()){   case MotionEvent.ACTION_DOWN:    if (running)     stop();    break;   case MotionEvent.ACTION_UP:   case MotionEvent.ACTION_CANCEL:   case MotionEvent.ACTION_OUTSIDE:    if (canRun)     start();    break;  }  return super.onTouchEvent(e); }}

开启:如果正在运行,先停止->再开启

public void start() {  if (running)   stop();  canRun = true;  running = true;  postDelayed(autoPollTask,TIME_AUTO_POLL); } public void stop(){  running = false;  removeCallbacks(autoPollTask); } @Override public boolean onTouchEvent(MotionEvent e) {  switch (e.getAction()){   case MotionEvent.ACTION_DOWN:    if (running)     stop();    break;   case MotionEvent.ACTION_UP:   case MotionEvent.ACTION_CANCEL:   case MotionEvent.ACTION_OUTSIDE:    if (canRun)     start();    break;  }  return super.onTouchEvent(e); }}

Adapter中的代码如下

@Override public void onBindViewHolder(BaseViewHolder holder, int position) {  String data = mData.get(position%mData.size());  holder.setText(R.id.tv_content,data); } @Override public int getItemCount() {  return Integer.MAX_VALUE; }

Activity中的代码

mRecyclerView.setAdapter(adapter);  if (true) //保证itemCount的总个数宽度超过屏幕宽度->自己处理   mRecyclerView.start();
