介绍：一个基于RecyclerView实现的ViewPager，支持类似于gallary的fling操作。点击上面"下载源码" 按钮，可以下载完整的demo。其中recyclerview是android-support中的依赖项目，RecyclerViewPager是主项目。运行效果：使用说明：继承自 RecyclerView.自定义 fling factor.自定义 paging trigger.支持 水平个垂直方向.支持 FragmentViewPager (api 12 )gradlecompile('com.lsjwzh:recyclerviewpager:1.0.2')xml:<com.lsjwzh.widget.recyclerviewpager.RecyclerViewPager     android:id="@ id/recyclerViewPager"     android:layout_width="match_parent"     android:layout_height="match_parent"     android:paddingLeft="15dp"     android:paddingRight="15dp"     app:triggerOffset="0.1"     android:clipToPadding="false"/>java:final RecyclerViewPager mRecyclerView = (RecyclerViewPager) this.findViewById(R.id.recyclerViewPager); LinearLayoutManager layout = new LinearLayoutManager(this, LinearLayoutManager.HORIZONTAL,false);//LinearLayoutManager.HORIZONTAL 设置水平滚动 mRecyclerView.setLayoutManager(layout); //set adapter mRecyclerView.setAdapter(new MyRecyclerAdapter());static class MyRecyclerAdapter extends RecyclerView.Adapter<MyRecyclerAdapter.ViewHolder> { private List<String> items = new ArrayList<String>(); public MyRecyclerAdapter(){ //创建4个页面 for(int i = 1; i<5; i ){ items.add("页面" i); } } public static class ViewHolder extends RecyclerView.ViewHolder{ public ViewHolder(View itemView) { super(itemView); } } @Override public int getItemCount() { // TODO Auto-generated method stub return items.size(); } @Override public void onBindViewHolder(ViewHolder holder, int position) { String item = items.get(position); TextView msgTv = (TextView)holder.itemView.findViewById(R.id.msg); msgTv.setText(item); } @Override public ViewHolder onCreateViewHolder(ViewGroup parent, int viewType) { if(inflate == null) inflate = (LayoutInflater) parent.getContext().getSystemService(Context.LAYOUT_INFLATER_SERVICE); View v = (LinearLayout)(inflate.inflate(R.layout.item, null)); return new ViewHolder(v); } }如果你想增加一些切换的特效：mRecyclerView.setOnScrollListener(new RecyclerView.OnScrollListener(){ @Override             public void onScrolled(RecyclerView recyclerView, int i, int i2) {//监听滚动，i为每次水平滚动的距离， i2为每次垂直滚动的距离 //                mPositionText.setText("First: "   mRecyclerView.getFirstVisiblePosition()); System.out.println("MainaActiv: i=" i  "  i2=" i2); //以下代码的作用是，使页面切换产生立体的效果                 int childCount = mRecyclerView.getChildCount();                 int width = mRecyclerView.getChildAt(0).getWidth();                 int padding = (mRecyclerView.getWidth() - width) / 2;                 for (int j = 0; j < childCount; j ) {                     View v = recyclerView.getChildAt(j);                     //往左 从 padding 到 -(v.getWidth()-padding) 的过程中，由大到小                     float rate = 0;                     ;                     if (v.getLeft() <= padding) {                         if (v.getLeft() >= padding - v.getWidth()) {                             rate = (padding - v.getLeft()) * 1f / v.getWidth();                         } else {                             rate = 1;                         }                         v.setScaleY(1 - rate * 0.1f);                         v.setScaleX(1 - rate * 0.1f);                     } else {                         //往右 从 padding 到 recyclerView.getWidth()-padding 的过程中，由大到小                         if (v.getLeft() <= recyclerView.getWidth() - padding) {                             rate = (recyclerView.getWidth() - padding - v.getLeft()) * 1f / v.getWidth();                         }                         v.setScaleY(0.9f   rate * 0.1f);                         v.setScaleX(0.9f   rate * 0.1f);                     }                 }             } }); mRecyclerView.addOnLayoutChangeListener(new View.OnLayoutChangeListener() {             @Override             public void onLayoutChange(View v, int left, int top, int right, int bottom, int oldLeft, int oldTop, int oldRight, int oldBottom) {                 if (mRecyclerView.getChildCount() < 3) {                     if (mRecyclerView.getChildAt(1) != null) {                         if(mRecyclerView.getCurrentPosition()==0) {                             View v1 = mRecyclerView.getChildAt(1);                             v1.setScaleY(0.9f);                             v1.setScaleX(0.9f);                         } else {                             View v1 = mRecyclerView.getChildAt(0);                             v1.setScaleY(0.9f);                             v1.setScaleX(0.9f);                         }                     }                 } else {                     if (mRecyclerView.getChildAt(0) != null) {                         View v0 = mRecyclerView.getChildAt(0);                         v0.setScaleY(0.9f);                         v0.setScaleX(0.9f);                     }                     if (mRecyclerView.getChildAt(2) != null) {                         View v2 = mRecyclerView.getChildAt(2);                         v2.setScaleY(0.9f);                         v2.setScaleX(0.9f);                     }                 }             }         }); }
