🥭🥭简介

分享一下recycleView在同一个页面中（一个recycleView中实现三种不同的布局方式）。三种布局一种是横着划，竖着划和GridView三种布局，代码全部粘在下面了，需要自取。

🍓🍓第一种是竖着滑动，和listView差不多。自我感觉，比ListView复杂。
🍓🍓第二种是横着滑。自我感觉，ListView虽然也可以实现，但是比起RecycleView难度和繁琐度都上了一个等级。这可能也是现在大部分人都用RecycleView的原因之一吧，当然recycleView还有很多优势。
🍓🍓第三种就是gridView布局了，也就是Android中常说的九宫格布局了。

RecycleView它可以实现与ListView和GridView一样的效果，提供了一种插拔式的体验，高度的解耦，异常的灵活，adpter适配器自己定制。只需设置其提供的不同的LayoutManager，ItemAnimator和ItemDecoration，就能实现不同的效果。

🍓🍓 RecyclerView的优点
🍗🍗1、支持局部刷新。
🍗🍗2、可以自定义item增删时的动画。
🍗🍗3、能够实现item拖拽和侧滑删除等功能。
🍗🍗4、默认已实现View的复用，而且回收机制更加完善。

🍎🍎三个Adapter修饰器

FruitAdapter

package Adapter;import Android.view.LayoutInflater;import android.view.View;import android.view.ViewGroup;import android.widget.ImageView;import android.widget.TextView;import androidx.annotation.NonNull;import androidx.recyclerview.widget.RecyclerView;import com.example.layout_test.R;import org.jetbrains.annotations.NotNull;import java.util.List;import domain.FuritBean;public class FruitAdapter extends RecyclerView.Adapter<FruitAdapter.ViewHolder> {    private List<FuritBean> mFruitList;    static class ViewHolder extends RecyclerView.ViewHolder{        private final ImageView mfruitImage;        private final TextView mfruitName;        public ViewHolder(@NonNull @NotNull View view) {            super(view);            mfruitImage=view.findViewById(R.id.mImg1);            mfruitName=view.findViewById(R.id.mTv1);        }    }    public FruitAdapter(List<FuritBean> fruitList){        mFruitList=fruitList;    }    @NonNull    @NotNull    @Override    public ViewHolder onCreateViewHolder(@NonNull @NotNull ViewGroup parent, int viewType) {        View view= LayoutInflater.from(parent.getContext()).inflate(R.layout.recycle_item1,parent,false);        ViewHolder holder=new ViewHolder(view);        return holder;    }    @Override    public void onBindViewHolder(@NonNull @NotNull FruitAdapter.ViewHolder holder, int position) {        FuritBean furit=mFruitList.get(position);        holder.mfruitImage.setImageResource(furit.getImageId());        holder.mfruitName.setText(furit.getName());    }    @Override    public int getItemCount() {        return mFruitList.size();    }}

FruitAdapter2

package Adapter;import android.view.LayoutInflater;import android.view.View;import android.view.ViewGroup;import android.widget.ImageView;import android.widget.TextView;import androidx.annotation.NonNull;import androidx.recyclerview.widget.RecyclerView;import com.example.layout_test.R;import org.jetbrains.annotations.NotNull;import java.util.List;import domain.FuritBean;public class FuritAdapter2 extends RecyclerView.Adapter<FuritAdapter2.ViewHolder> {    private List<FuritBean> mFruitList;    static class ViewHolder extends RecyclerView.ViewHolder{        private final ImageView mfruitImage;        private final TextView mfruitName;        public ViewHolder(@NonNull @NotNull View itemView) {            super(itemView);            mfruitImage= itemView.findViewById(R.id.mImg2);            mfruitName = itemView.findViewById(R.id.mTv2);        }    }    public FuritAdapter2(List<FuritBean> mFruitList) {        this.mFruitList = mFruitList;    }    @NonNull    @Override    public FuritAdapter2.ViewHolder onCreateViewHolder(@NonNull @NotNull ViewGroup parent, int viewType) {        View view= LayoutInflater.from(parent.getContext()).inflate(R.layout.recycle_item2,parent,false);        ViewHolder viewHolder=new ViewHolder(view);        return viewHolder;    }    @Override    public void onBindViewHolder(@NonNull @NotNull FuritAdapter2.ViewHolder holder, int position) {        FuritBean furit=mFruitList.get(position);        holder.mfruitImage.setImageResource(furit.getImageId());        holder.mfruitName.setText(furit.getName());    }    @Override    public int getItemCount() {        return mFruitList.size();    }}

FruitAdapter3

package Adapter;import android.view.LayoutInflater;import android.view.View;import android.view.ViewGroup;import android.widget.ImageView;import android.widget.TextView;import androidx.annotation.NonNull;import androidx.recyclerview.widget.RecyclerView;import com.example.layout_test.R;import org.jetbrains.annotations.NotNull;import java.util.List;import domain.FuritBean;public class FuritAdapter3 extends RecyclerView.Adapter<FuritAdapter3.ViewHolder> {    private List<FuritBean> mFruitList;    static class ViewHolder extends RecyclerView.ViewHolder{        private final ImageView mfruitImage;        private final TextView mfruitName;        public ViewHolder(@NonNull @NotNull View itemView) {            super(itemView);            mfruitImage= itemView.findViewById(R.id.mImg3);            mfruitName = itemView.findViewById(R.id.mTv3);        }    }    public FuritAdapter3(List<FuritBean> mFruitList) {        this.mFruitList = mFruitList;    }    @NonNull    @Override    public FuritAdapter3.ViewHolder onCreateViewHolder(@NonNull @NotNull ViewGroup parent, int viewType) {        View view= LayoutInflater.from(parent.getContext()).inflate(R.layout.recycle_item3,parent,false);        ViewHolder viewHolder=new ViewHolder(view);        return viewHolder;    }    @Override    public void onBindViewHolder(@NonNull @NotNull FuritAdapter3.ViewHolder holder, int position) {        FuritBean furit=mFruitList.get(position);        holder.mfruitImage.setImageResource(furit.getImageId());        holder.mfruitName.setText(furit.getName());    }    @Override    public int getItemCount() {        return mFruitList.size();    }}

三个Adapter修饰器修饰了不同的布局，每一个布局都是单独修饰的，当然也可以放到一个布局里面。下面一篇文章会将所有的布局放在一个Adapter修饰器里面进行。

嗯~~，就几张照片，放上来还有水印，你们这个照片就自己找找吧。

把上面的代码全部拷贝下来就可以运行出上动态图的结果了。
