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

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.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.support.v7.widget.LinearLayoutManager;

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...
