基于RecyclerView实现横向GridView效果

作者：袖梨 2022-06-25

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

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： 




 

 

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;

/**

 */
public class MyRVAdapter extends RecyclerView.Adapter {
 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;
 }
}
