本文实例为大家分享了RecyclerView实现横向GridView效果展示的具体代码，供大家参考，具体内容如下
要使用RecyclerView，首先要在build.gradle文件中添加依赖compile 'com.android.support:appcompat-v7:24.1.0'
效果图
布局如下
<?xml version="1.0" encoding="utf-8"?><RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android" xmlns:tools="http://schemas.android.com/tools" android:layout_width="match_parent" android:layout_height="match_parent" tools:context="com.dxx.recycleviewtestdemo.MainActivity"> <android.support.v7.widget.RecyclerView android:id="@+id/rv" android:layout_width="match_parent" android:layout_height="200dp" android:layout_margin="20dp"/></RelativeLayout>
使用方法:
package com.dxx.recycleviewtestdemo;import android.os.Bundle;import android.support.v7.app.AppCompatActivity;import android.support.v7.widget.LinearLayoutManager;import android.support.v7.widget.RecyclerView;public class MainActivity extends AppCompatActivity { @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_main); RecyclerView rv = (RecyclerView) findViewById(R.id.rv); rv.setLayoutManager(new LinearLayoutManager(this,LinearLayoutManager.HORIZONTAL,false));//设置布局管理器 rv.setAdapter(new MyRVAdapter(this)); }} 其Adapter要继承RecyclerView.Adapter,在Adapter中药先定义ViewHolder，并继承RecyclerView.ViewHolder;如：
public class ViewHolder extends RecyclerView.ViewHolder{ public ViewHolder(View itemView) { super(itemView); } ImageView rv_item_image; TextView rv_item_tv; } 在onCreateViewHolder进行初始化操作，在onBindViewHolder中对各种事件进行处理,getItemCount返回的是 RecyclerView的长度，其布局与代码如下：
<?xml version="1.0" encoding="utf-8"?><LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="wrap_content" android:layout_height="wrap_content" android:gravity="center" android:layout_marginLeft="18dp" android:layout_marginBottom="5dp" android:orientation="vertical"> <ImageView android:id="@+id/rv_item_image" android:layout_width="82dp" android:layout_height="82dp" android:scaleType="centerCrop" android:src="@drawable/shiqikuangsan"/> <TextView android:id="@+id/rv_item_tv" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_marginTop="9dp" android:textSize="15sp"/></LinearLayout>
package com.dxx.recycleviewtestdemo;import android.content.Context;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;/** * Created by duxiaxing on 2016/7/27. */public class MyRVAdapter extends RecyclerView.Adapter<MyRVAdapter.ViewHolder> { private Context context; public MyRVAdapter(Context context){ this.context = context; } @Override public ViewHolder onCreateViewHolder(ViewGroup parent, int viewType) { View view = LayoutInflater.from(context).inflate(R.layout.layout_rv_item,parent,false); ViewHolder holder = new ViewHolder(view); holder.rv_item_image = (ImageView) view.findViewById(R.id.rv_item_image); holder.rv_item_tv = (TextView) view.findViewById(R.id.rv_item_tv); return holder; } @Override public void onBindViewHolder(ViewHolder holder, int position) { holder.rv_item_tv.setText(position + ""); } @Override public int getItemCount() { return 9; } public class ViewHolder extends RecyclerView.ViewHolder{ public ViewHolder(View itemView) { super(itemView); } ImageView rv_item_image; TextView rv_item_tv; }} 以上就是本文的全部内容，希望对大家的学习有所帮助，也希望大家多多支持VEVB武林网。
