android recyclerview 水平,使用RecyclerView实现水平列表

本文实例为大家分享了RecyclerView实现水平列表的具体代码，供大家参考，具体内容如下

1、效果图

2、activity_horizontallistview.xml

android:layout_width="match_parent"

android:layout_height="match_parent"

android:orientation="vertical">

android:id="@+id/recyclerview_horizontal1"

android:layout_width="wrap_content"

android:layout_height="wrap_content"

android:layout_gravity="center_horizontal"

android:overScrollMode="never"

android:scrollbars="none"

/>

android:id="@+id/recyclerview_horizontal2"

android:layout_width="wrap_content"

android:layout_height="wrap_content"

android:layout_gravity="center_horizontal"

android:overScrollMode="never"

android:scrollbars="none"

/>

android:id="@+id/recyclerview_horizontal3"

android:layout_width="wrap_content"

android:layout_height="wrap_content"

android:layout_gravity="center_horizontal"

android:overScrollMode="never"

android:scrollbars="none"

/>

3、activity代码

package ivan.com.appbackendtest;

import android.content.Context;

import android.os.Bundle;

import android.support.v7.app.AppCompatActivity;

import android.support.v7.widget.LinearLayoutManager;

import android.support.v7.widget.RecyclerView;

import android.view.LayoutInflater;

import android.view.View;

import android.view.ViewGroup;

import android.widget.ImageView;

import android.widget.TextView;

import java.util.ArrayList;

import java.util.Arrays;

import java.util.List;

public class HorizontalListviewActivity extends AppCompatActivity {

private RecyclerView recyclerview_horizontal1;

private GalleryAdapter mAdapter1;

private RecyclerView recyclerview_horizontal2;

private GalleryAdapter mAdapter2;

private RecyclerView recyclerview_horizontal3;

private GalleryAdapter mAdapter3;

private List mDatas1;

private List mDatas2;

private List mDatas3;

@Override

protected void onCreate(Bundle savedInstanceState) {

super.onCreate(savedInstanceState);

setContentView(R.layout.activity_horizontallistview);

initDatas();

//得到控件

recyclerview_horizontal1 = (RecyclerView)findViewById(R.id.recyclerview_horizontal1);

//设置布局管理器

LinearLayoutManager linearLayoutManager = new LinearLayoutManager(this);

linearLayoutManager.setOrientation(LinearLayoutManager.HORIZONTAL);

recyclerview_horizontal1.setLayoutManager(linearLayoutManager);

//设置适配器

mAdapter1 = new GalleryAdapter(this,mDatas1);

recyclerview_horizontal1.setAdapter(mAdapter1);

//得到控件

recyclerview_horizontal2 = (RecyclerView)findViewById(R.id.recyclerview_horizontal2);

//设置布局管理器

LinearLayoutManager linearLayoutManager2 = new LinearLayoutManager(this);

linearLayoutManager2.setOrientation(LinearLayoutManager.HORIZONTAL);

recyclerview_horizontal2.setLayoutManager(linearLayoutManager2);

//设置适配器

mAdapter2 = new GalleryAdapter(this,mDatas2);

recyclerview_horizontal2.setAdapter(mAdapter2);

//得到控件

recyclerview_horizontal3 = (RecyclerView)findViewById(R.id.recyclerview_horizontal3);

//设置布局管理器

LinearLayoutManager linearLayoutManager3 = new LinearLayoutManager(this);

linearLayoutManager3.setOrientation(LinearLayoutManager.HORIZONTAL);

recyclerview_horizontal3.setLayoutManager(linearLayoutManager3);

//设置适配器

mAdapter3 = new GalleryAdapter(this,mDatas3);

recyclerview_horizontal3.setAdapter(mAdapter3);

}

private void initDatas()

{

mDatas1 = new ArrayList<>(Arrays.asList(R.mipmap.ic_launcher));

mDatas2 = new ArrayList<>(Arrays.asList(R.mipmap.ic_launcher,R.mipmap.ic_launcher));

mDatas3 = new ArrayList<>(Arrays.asList(R.mipmap.ic_launcher,R.mipmap.ic_launcher,R.mipmap.ic_launcher));

}

public class GalleryAdapter extends

RecyclerView.Adapter

{

private LayoutInflater mInflater;

private List mDatas;

public GalleryAdapter(Context context,List datats)

{

mInflater = LayoutInflater.from(context);

mDatas = datats;

}

public class ViewHolder extends RecyclerView.ViewHolder

{

public ViewHolder(View arg0)

{

super(arg0);

}

ImageView mImg;

TextView mTxt;

}

@Override

public int getItemCount()

{

return mDatas.size();

}

/**

* 创建ViewHolder

*/

@Override

public ViewHolder onCreateViewHolder(ViewGroup viewGroup,int i)

{

View view = mInflater.inflate(R.layout.item_listview,viewGroup,false);

ViewHolder viewHolder = new ViewHolder(view);

viewHolder.mImg = (ImageView) view

.findViewById(R.id.id_index_gallery_item_image);

return viewHolder;

}

/**

* 设置值

*/

@Override

public void onBindViewHolder(final ViewHolder viewHolder,final int i)

{

viewHolder.mImg.setImageResource(mDatas.get(i));

}

}

}

4、核心代码

//得到控件

recyclerview_horizontal1 = (RecyclerView)findViewById(R.id.recyclerview_horizontal1);

//设置布局管理器

LinearLayoutManager linearLayoutManager = new LinearLayoutManager(this);

linearLayoutManager.setOrientation(LinearLayoutManager.HORIZONTAL);

recyclerview_horizontal1.setLayoutManager(linearLayoutManager);

//设置适配器

mAdapter1 = new GalleryAdapter(this,mDatas1);

recyclerview_horizontal1.setAdapter(mAdapter1);
