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

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical">

<android.support.v7.widget.RecyclerView
 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.support.v7.widget.RecyclerView
 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.support.v7.widget.RecyclerView
 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"
 />
</LinearLayout>

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<Integer> mDatas1;
private List<Integer> mDatas2;
private List<Integer> 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

//得到控件

}
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,R.mipmap.ic_launcher,R.mipmap.ic_launcher,R.mipmap.ic_launcher));
}
public class GalleryAdapter extends
  RecyclerView.Adapter<GalleryAdapter.ViewHolder>
{
 private LayoutInflater mInflater;
 private List<Integer> mDatas;

public GalleryAdapter(Context context, List<Integer> 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);
