Android 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

package com.test.administrator.testapp;import android.graphics.Color;import android.support.v7.app.AppCompatActivity;import android.os.Bundle;import android.support.v7.widget.LinearLayoutManager;import android.support.v7.widget.RecyclerView;import android.util.Log;import android.widget.Toast;import com.jude.rollviewpager.RollPagerView;import com.jude.rollviewpager.hintview.ColorPointHintView;import java.util.ArrayList;import java.util.HashMap;import java.util.List;import java.util.Map;import java.util.Objects;public class MainActivity extends AppCompatActivity {private RecyclerView recyclerView;    private List<Map<String,Object>> list=new ArrayList<>();    private RecAdapter recAdapter;    @Override    protected void onCreate(Bundle savedInstanceState) {        super.onCreate(savedInstanceState);        setContentView(R.layout.activity_main);        initView();        initData();        initCtrl();        recyclerView.setAdapter(recAdapter);        recAdapter.setList(list);    }    private void initCtrl() {        recAdapter=new RecAdapter(this,list);        RecyclerView.LayoutManager manager = new LinearLayoutManager(MainActivity.this, LinearLayoutManager.VERTICAL, false);        recyclerView.setLayoutManager(manager);    }    private void initView() {        recyclerView= (RecyclerView) findViewById(R.id.recyclerView);    }    private void initData() {        Map<String,Object> map00=new HashMap<String, Object>();        map00.put("img",R.drawable.img1);        map00.put("txt","00");        list.add(map00);        Map<String,Object> map01=new HashMap<String, Object>();        map01.put("img",R.drawable.img2);        map01.put("txt","01");        list.add(map01);        Map<String,Object> map02=new HashMap<String, Object>();        map02.put("img",R.drawable.img2);        map02.put("txt","02");        list.add(map02);    }}

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,    };    @Override    public 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;    }    @Override    public int getCount() {        return imgs.length;    }}

这样子就实现了...
