[文章] no，也可以竖着滚动，ViewPager.PageTransformer有奇效，简单实例，复制粘贴就有效果。

这里要实现的就是ViewPager的垂直滚动。先上效果图了。https://chuantu.xyz/t6/703/1575879903x2728278915.gif前方高能，注意代码。第一，MainActivitypublicclassMainActivityextendsActivity{privateVerticalViewPagermViewPager;//下面三张图片自己截取一下添加到mipmap中就ok。privateint[]mImgIds=newint[]{R.mipmap.nvhaione,R.mipmap.nvhaitwo,R.mipmap.nvhaithree};privateList<ImageView>mImageViews=newArrayList<ImageView>();@OverrideprotectedvoidonCreate(BundlesavedInstanceState){super.onCreate(savedInstanceState);requestWindowFeature(Window.FEATURE_NO_TITLE);setContentView(R.layout.activity_main);initData();//下面这个VerticalViewPager不要写错哦。mViewPager=(VerticalViewPager)findViewById(R.id.id_viewpager);mViewPager.setAdapter(newPagerAdapter(){@OverridepublicObjectinstantiateItem(ViewGroupcontainer,intposition){container.addView(mImageViews.get(position));returnmImageViews.get(position);}@OverridepublicvoiddestroyItem(ViewGroupcontainer,intposition,Objectobject){container.removeView(mImageViews.get(position));}@OverridepublicbooleanisViewFromObject(Viewview,Objectobject){returnview==object;}@OverridepublicintgetCount(){returnmImgIds.length;}});}//数据初始化privatevoidinitData(){for(intimgId:mImgIds){ImageViewimageView=newImageView(getApplicationContext());imageView.setScaleType(ImageView.ScaleType.CENTER_CROP);imageView.setImageResource(imgId);mImageViews.add(imageView);}}}第二，VerticalViewPagerpublicclassVerticalViewPagerextendsViewPager{publicVerticalViewPager(Contextcontext){this(context,null);}publicVerticalViewPager(Contextcontext,AttributeSetattrs){super(context,attrs);//设置viewpage的切换动画,这里设置才能真正实现垂直滑动的viewpagersetPageTransformer(true,newVerticalPageTransformer());}/***----------------调整xy方向--------------------------------*/@OverridepublicbooleanonInterceptTouchEvent(MotionEventev){booleanintercept=super.onInterceptTouchEvent(swapEvent(ev));swapEvent(ev);returnintercept;}@OverridepublicbooleanonTouchEvent(MotionEventev){returnsuper.onTouchEvent(swapEvent(ev));}privateMotionEventswapEvent(MotionEventevent){//获取宽高floatwidth=getWidth();floatheight=getHeight();//将Y轴的移动距离转变成X轴的移动距离floatswappedX=(event.getY()/height)*width;//将X轴的移动距离转变成Y轴的移动距离floatswappedY=(event.getX()/width)*height;//重设event的位置event.setLocation(swappedX,swappedY);returnevent;}/***----------------------实现PageTransformer重写。-----------------------------*/publicclassVerticalPageTransformerimplementsViewPager.PageTransformer{@OverridepublicvoidtransformPage(Viewview,floatposition){if(position<-1){//[-Infinity,-1)//Thispageiswayoff-screentotheleft.view.setAlpha(0);}elseif(position<=1){//[-1,1]view.setAlpha(1);//Counteractthedefaultslidetransitionview.setTranslationX(view.getWidth()*-position);//setYpositiontoswipeinfromtopfloatyPosition=position*view.getHeight();view.setTranslationY(yPosition);}else{//(1,+Infinity]//Thispageiswayoff-screentotheright.view.setAlpha(0);}}}}第三：activity_main.xml<RelativeLayoutxmlns:android="https://schemas.android.com/apk/res/android"xmlns:tools="https://schemas.android.com/tools"android:layout_width="match_parent"android:layout_height="match_parent"><com.xxxxxx.yyyyyyactivity.VerticalViewPagerandroid:id="@+id/id_viewpager"android:layout_marginTop="20dp"android:layout_marginBottom="20dp"android:background="#6666"android:layout_width="match_parent"android:layout_height="match_parent"/></RelativeLayout>第四：容易出错的地方activity_main.xml中的<com.xxxxxx.yyyyyyactivity.VerticalViewPager>这个是你自己的包名+上面自己新建的VerticalViewPager。OK，看到这里了，那么重点来了，点个赞呗！！！
