RecyclerView 是Android L版本中新添加的一个用来取代ListView的SDK,它的灵活性与可替代性比listview更好。本文给大家介绍Android中RecyclerView实现横向滑动代码，一起看看吧。
android.support.v7.widget.RecyclerView
功能：RecyclerView横向滑动
控件：
Java类：RecyclerView、GalleryAdapter、List
1、主界面布局
2、子界面布局
3、Java代码
package com.info.activity;
import android.app.Activity;
import android.content.Context;
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
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 RecyclerActivity extends Activity {
private RecyclerView mRecyclerView;
private GalleryAdapter mAdapter;
private List mDatas;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_recycler);
initDatas();
//得到控件
mRecyclerView = (RecyclerView) findViewById(R.id.id_recyclerview_horizontal);
//设置布局管理器
LinearLayoutManager linearLayoutManager = new LinearLayoutManager(this);
linearLayoutManager.setOrientation(LinearLayoutManager.HORIZONTAL);
mRecyclerView.setLayoutManager(linearLayoutManager);
//设置适配器
mAdapter = new GalleryAdapter(this, mDatas);
mRecyclerView.setAdapter(mAdapter);
}
private void initDatas()
{
mDatas = new ArrayList<>(Arrays.asList(R.drawable.ic_launcher,
R.drawable.ic_launcher, R.drawable.ic_launcher, R.drawable.ic_launcher, R.drawable.ic_launcher,
R.drawable.ic_launcher, R.drawable.ic_launcher, R.drawable.ic_launcher, R.drawable.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();
}
@Override
public ViewHolder onCreateViewHolder(ViewGroup viewGroup, int i)
{
View view = mInflater.inflate(R.layout.activity_recycler_item,
viewGroup, false);
ViewHolder viewHolder = new ViewHolder(view);
viewHolder.mImg = (ImageView) view
.findViewById(R.id.id_index_gallery_item_image);
return viewHolder;
}
@Override
public void onBindViewHolder(final ViewHolder viewHolder, final int i)
{
viewHolder.mImg.setImageResource(mDatas.get(i));
}
}
}
