1.写一个内容的自定义小布局:
<?xml version="1.0" encoding="utf-8"?> <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:orientation="vertical" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_margin="10dp"> <ImageView android:id="@+id/waterfall_Image" android:layout_width="wrap_content" android:layout_height="wrap_content" android:src="@drawable/ace"/> <TextView android:id="@+id/waterfall_Name_TextView" android:layout_width="wrap_content" android:layout_height="wrap_content" android:text="这里显示名称" android:textSize="15sp" android:textColor="@color/colorBlack" android:layout_gravity="center_horizontal"/> <TextView android:id="@+id/waterfall_contents_TextView" android:layout_width="wrap_content" android:layout_height="wrap_content" android:text="这里显示内容" android:textSize="10sp" android:textColor="@color/colorblue"/> </LinearLayout>
布局预览:
写一个内容适配器class:
package com.example.lenovo.myrecyclerview.RecyclerViewToolkit; 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.example.lenovo.myrecyclerview.R; import java.util.List; /** * Created by lenovo on 2018/5/2. */ public class ListAdapter extends RecyclerView.Adapter<ListAdapter.ViewHolder> { private List<ListData> mDataList; static class ViewHolder extends RecyclerView.ViewHolder{ ImageView imageAvatar; TextView nameText; TextView contentsText; public ViewHolder(View itemView) { super(itemView); //注意这里可能需要import com.example.lenovo.myrecyclerview.R; 才能使用R.id imageAvatar = (ImageView)itemView.findViewById(R.id.waterfall_Image); nameText =(TextView) itemView.findViewById(R.id.waterfall_Name_TextView); contentsText = (TextView)itemView.findViewById(R.id.waterfall_contents_TextView); } } public ListAdapter(List<ListData> listDatas){ mDataList = listDatas; } @Override public ViewHolder onCreateViewHolder(ViewGroup parent, int viewType) { View view = LayoutInflater.from(parent.getContext()).inflate(R.layout.waterfall_list_view, parent,false); ViewHolder holder = new ViewHolder(view); return holder; } @Override public void onBindViewHolder(ViewHolder holder, int position) { ListData listData = mDataList.get(position); holder.imageAvatar.setImageResource(listData.getImageView()); holder.nameText.setText(listData.getNameText()); holder.contentsText.setText(listData.getContentsText()); } @Override public int getItemCount() { return mDataList.size(); } }
写一个RecyclerView 瀑布列表布局活动class:
package com.example.lenovo.myrecyclerview; import android.support.v7.app.AppCompatActivity; import android.os.Bundle; import android.support.v7.widget.LinearLayoutManager; import android.support.v7.widget.RecyclerView; import android.support.v7.widget.StaggeredGridLayoutManager; import com.example.lenovo.myrecyclerview.RecyclerViewToolkit.ListAdapter; import com.example.lenovo.myrecyclerview.RecyclerViewToolkit.ListData; import java.util.ArrayList; import java.util.List; public class RecyclerViewActivity extends AppCompatActivity { private List<ListData> listDatas = new ArrayList<>(); //创建数据list @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_recycler_view); addingData(); //导入数据 RecyclerView recyclerView = (RecyclerView)findViewById(R.id.RecyclerView); //在此处修改布局排列方向 StaggeredGridLayoutManager staggeredGridLayoutManager = new StaggeredGridLayoutManager(3, StaggeredGridLayoutManager.VERTICAL); recyclerView.setLayoutManager(staggeredGridLayoutManager); ListAdapter listAdapter = new ListAdapter(listDatas); //创建适配器,并且导入数据list recyclerView.setAdapter(listAdapter);//布局导入适配器 } //添加数据 public void addingData(){ ListData ace = new ListData(R.drawable.ace,"ace", "波特卡斯·D·艾斯:" + "烧烧果实的前任能力者,绰号“火拳”,实力强大。"); listDatas.add(ace); //以下省略..... } }
