And 4000 roid RecyclerView实现多布局切换功能从导入到运行详解,,上方图片轮播,下方多布局加载

这个RecyclerView 感觉和它命里面相冲,几次想用 都不成功,现在说一下自己的几点想法和意见    1,首先是导入:           一定要记住:你的API等级要过了21                               你的API等级要过21                             你的API等级要过21                重要的话重复三遍........            其次还要注意的是你的V4包和导入的RecyclerView的版本一致,最后我找了很久版本一致,如果你的V4包是AS线上的,你一定要用线上的RecyclerView .如果你的V4包是线下的,你一定要用线下的RecyclerView. 还有就是版本,版本一致. 还有就是与V7包版本一致.  如果不一致,你就会出现             你的recyclerView包缺类的问题            你的recyclerView包缺类              重要的说两遍最后我用的是

compile 'com.android.support:appcompat-v7:23.3.0'compile 'com.android.support:recyclerview-v7:23.3.0'

 这样 我终于导入了recyclerView .         2,其次就是多布局的问题了 我这里结合了RollPagerView这个第三方控件 上边实现轮播 下边是listview样式的加载MainActivity里面

TestNormalAdapter

package com.test.administrator.testapp;import android.view.View;import android.view.ViewGroup;import android.widget.ImageView;import com.jude.rollviewpager.adapter.StaticPagerAdapter;/*** Created by Administrator on 2016/10/8 0008.*/public class TestNormalAdapter extends StaticPagerAdapter {private int[] imgs = {R.drawable.img1,R.drawable.img2,R.drawable.img3,R.drawable.img4,};@Overridepublic View getView(ViewGroup container, int position) {ImageView view = new ImageView(container.getContext());view.setImageResource(imgs[position]);view.setScaleType(ImageView.ScaleType.CENTER_CROP);view.setLayoutParams(new ViewGroup.LayoutParams(ViewGroup.LayoutParams.MATCH_PARENT, ViewGroup.LayoutParams.MATCH_PARENT));return view;}@Overridepublic int getCount() {return imgs.length;}}

这样子就实现了...
