本文实例为大家分享了RecylerView实现流布局的具体代码，供大家参考，具体内容如下

第一步：添加依赖

compile 'com.android.support:appcompat-v7:25.3.1'compile 'com.android.support:design:25.3.1'compile 'com.android.support:recyclerview-v7:25.3.1'compile 'com.android.support:cardview-v7:25.3.1'compile 'com.github.bumptech.glide:glide:3.7.0'

因为加载的是网络图片，所以采用的是Glide图片加载框架。

第二步：recylerview布局 (刷新需要添加SwipeRefreshLayout)

<?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.example.wangchang.testpalette.MainActivity"> <android.support.v7.widget.RecyclerView android:id="@+id/recylerview" android:padding="4dp" android:layout_width="match_parent" android:layout_height="match_parent" /></RelativeLayout>

第三步：RecylerView初始化

recyclerView = (RecyclerView) findViewById(R.id.recylerview); recyclerView.setHasFixedSize(true); recyclerView.setLayoutManager(new StaggeredGridLayoutManager(2, StaggeredGridLayoutManager.VERTICAL)); recyclerView.setAdapter(adapter = new DemoAdapter()); adapter.replaceAll(getData());

Demo中：

final StaggeredGridLayoutManager layoutManager = new StaggeredGridLayoutManager(2, StaggeredGridLayoutManager.VERTICAL); mRecyclerView.setLayoutManager(layoutManager); mMeizhiListAdapter = new MeizhiListAdapter(getContext(), mMeizhiList); mRecyclerView.setAdapter(mMeizhiListAdapter); mRecyclerView.addOnScrollListener(getOnBottomListener(layoutManager));//滚动预先加载数据 mMeizhiListAdapter.setOnMeizhiTouchListener(getOnMeizhiTouchListener());//点击事件

这里主要是 recyclerView.setLayoutManager(new StaggeredGridLayoutManager(2, StaggeredGridLayoutManager.VERTICAL)); 设置StaggeredGridLayoutManager布局管理器，参数分别是列数，方向。

第四步：适配器的实现

package com.hsy.utils.utilsdemo.adapter;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;import com.hsy.utils.utilsdemo.R;import com.hsy.utils.utilsdemo.module.home.Daily;import com.hsy.utils.utilslibrary.utils.GlideUtils;import java.util.List;/** * Created by drakeet on 6/20/15. */public class MeizhiListAdapter extends RecyclerView.Adapter<MeizhiListAdapter.ViewHolder> { public static final String TAG = "MeizhiListAdapter"; private List<Daily> mList; private Context mContext; private OnMeizhiTouchListener mOnMeizhiTouchListener; public MeizhiListAdapter(Context context, List<Daily> meizhiList) { mList = meizhiList; mContext = context; } @Override public ViewHolder onCreateViewHolder(ViewGroup parent, int i) { View v = LayoutInflater.from(parent.getContext()) .inflate(R.layout.item_meizhi, parent, false); return new ViewHolder(v); } @Override public void onBindViewHolder(final ViewHolder viewHolder, final int position) { Daily meizhi = mList.get(position); int limit = 48; String text = ""; if (meizhi != null && meizhi.getTitle() != null) { text = meizhi.getTitle().length() > limit ? meizhi.getTitle().substring(0, limit) + "..." : meizhi.getTitle(); } viewHolder.meizhi = meizhi; viewHolder.titleView.setText(text); viewHolder.card.setTag(meizhi.getDesc());//加载图片 GlideUtils.displayImage(mContext, meizhi.getImgUrl(), viewHolder.meizhiView); } @Override public void onViewRecycled(ViewHolder holder) { super.onViewRecycled(holder); } @Override public int getItemCount() { return mList != null ? mList.size() : 0; } public void setOnMeizhiTouchListener(OnMeizhiTouchListener onMeizhiTouchListener) { this.mOnMeizhiTouchListener = onMeizhiTouchListener; } class ViewHolder extends RecyclerView.ViewHolder implements View.OnClickListener { ImageView meizhiView; TextView titleView; View card; Daily meizhi; public ViewHolder(View itemView) { super(itemView); card = itemView; meizhiView = (ImageView) itemView.findViewById(R.id.meizhi); titleView = (TextView) itemView.findViewById(R.id.title); meizhiView.setOnClickListener(this); card.setOnClickListener(this); itemView.setOnClickListener(this); } @Override public void onClick(View v) { mOnMeizhiTouchListener.onTouch(v, meizhiView, card, meizhi); } }}

每个布局的样式item_layout

<?xml version="1.0" encoding="utf-8"?><android.support.v7.widget.CardView xmlns:android="http://schemas.android.com/apk/res/android" xmlns:tools="http://schemas.android.com/tools" android:layout_width="match_parent" android:layout_height="wrap_content" android:layout_marginLeft="5dp" android:layout_marginRight="5dp" android:layout_marginTop="5dp"> <LinearLayout android:id="@+id/meizhi_card" android:layout_width="match_parent" android:layout_height="wrap_content" android:clickable="true" android:orientation="vertical"> <!-- android:background="@drawable/bg_card"--> <ImageView android:id="@+id/meizhi" android:layout_width="match_parent" android:layout_height="wrap_content" android:adjustViewBounds="true" android:scaleType="fitXY" /> <LinearLayout android:layout_width="match_parent" android:layout_height="wrap_content" android:background="?attr/selectableItemBackground" android:orientation="horizontal" android:paddingBottom="10dp" android:paddingLeft="10dp" android:paddingRight="10dp" android:paddingTop="10dp"> <TextView android:id="@+id/title" android:layout_width="wrap_content" android:layout_height="wrap_content" android:textAppearance="?android:attr/textAppearanceSmall" tools:text="Title" /> </LinearLayout> </LinearLayout></android.support.v7.widget.CardView>

下面来说实现动态设置图片大小方式

ivImage.getContext()).getWindowManager().getDefaultDisplay().getWidth(); ViewGroup.LayoutParams params = ivImage.getLayoutParams(); //设置图片的相对于屏幕的宽高比 params.width = width/3; params.height = (int) (200 + Math.random() * 400) ; ivImage.setLayoutParams(params);

这里是获取屏幕宽度，因为是三列，所以设置图片宽度取屏幕三分之一。
