android 底部横向滑动,Android中RecyclerView实现横向滑动代码

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

xmlns:tools="http://schemas.android.com/tools"

android:layout_width="match_parent"

android:layout_height="match_parent"

android:paddingBottom="@dimen/activity_vertical_margin"

android:paddingLeft="@dimen/activity_horizontal_margin"

android:paddingRight="@dimen/activity_horizontal_margin"

android:paddingTop="@dimen/activity_vertical_margin"

tools:context="com.info.activity.RecyclerActivity">

android:id="@+id/id_recyclerview_horizontal"

android:layout_width="match_parent"

android:layout_height="120dp"

android:layout_centerVertical="true"

android:background="#FF0000"

android:scrollbars="none"

>

2、子界面布局

android:layout_width="120dp"

android:layout_height="120dp">

android:id="@+id/id_index_gallery_item_image"

android:layout_width="80dp"

android:layout_height="80dp"

android:layout_alignParentTop="true"

android:layout_centerHorizontal="true"

android:layout_margin="5dp"

android:scaleType="centerCrop" />

android:id="@+id/id_index_gallery_item_text"

android:layout_width="wrap_content"

android:layout_height="wrap_content"

android:layout_below="@id/id_index_gallery_item_image"

android:layout_centerHorizontal="true"

android:layout_marginBottom="5dp"

android:layout_marginTop="5dp"

android:textColor="#000000"

android:text="some info"

android:textSize="12dp" />

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();

}

/**

* 创建ViewHolder

*/

@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;

}

/**

* 设置值

*/

@Override

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

{

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

}

}

}
