/> 关于RecyclerView的item布局和适配器代码不变，便于集中学习这里贴出适配器RecyclerViewAdapter...extends RecyclerView.Adapter { private ArrayList mDatas...= null; private LayoutInflater mInflater = null; public RecyclerViewAdapter(Context context,...android.support.v7.widget.RecyclerView; import com.jinyu.cqkxzsxy.android.advancedviewsample.adapter.RecyclerViewAdapter...SwipeRefreshLayout mSwipeView = null; private RecyclerView mRecyclerView = null; private RecyclerViewAdapter
首先在RecyclerViewAdapter类中分别定义2个接口OnItemClickListener和OnItemLongClickListener，然后提供2个公开方法便于Activity设置事件监听...RecyclerViewAdapter类修改后的代码如下： package com.jinyu.cqkxzsxy.android.advancedviewsample.adapter; import...extends RecyclerView.Adapter { private ArrayList mDatas..., RecyclerViewAdapter.OnItemLongClickListener { private RecyclerView mRecyclerView = null...; private RecyclerViewAdapter mAdapter = null; private ArrayList mDatas = null;
extends RecyclerView.Adapter<RecyclerViewAdapter.ViewHolder { private Context mContext; private...); tvSend = itemView.findViewById(R.id.Layout_Item_Content_tvContentSend); } } public RecyclerViewAdapter...private List<Tb_ChatContent tbChatContentList; private Tb_ChatContent tb_chatContent; private RecyclerViewAdapter...recyclerViewAdapter; private String[] arrayContents = new String[]{"How are you", "Fine,Thank you...= new RecyclerViewAdapter(mContext, tbChatContentList); rViewChat.setAdapter(recyclerViewAdapter
继续使用上期的案例，首先在RecyclerViewAdapter类中新增一个插入和删除处理的公开方法，RecyclerViewAdapter类修改后的代码如下： package com.jinyu.cqkxzsxy.android.advancedviewsample.adapter...java.util.ArrayList; /** * @创建者 鑫鱻 * @描述 Android零基础入门到精通系列教程 * 首发微信公众号分享达人秀（ShareExpert） */ public class RecyclerViewAdapter...extends RecyclerView.Adapter { private ArrayList mDatas..., RecyclerViewAdapter.OnItemLongClickListener { private RecyclerView mRecyclerView = null...; private RecyclerViewAdapter mAdapter = null; private ArrayList mDatas = null;
通过以上常用属性可以使CardView出现各种不同的效果 现在回到Activity中来实现RecyclerView 跟ListView的一样，我们需要写一个适配器，代码如下： public class recyclerViewadapter...extends RecyclerView.Adapter { private List<DataBean lists; private Context context; public recyclerViewadapter...getContext()); m.setOrientation(LinearLayoutManager.HORIZONTAL); recycler_view.setLayoutManager(m); recyclerViewadapter...adapter=new recyclerViewadapter(lists,getContext()); recycler_view.setAdapter(adapter); return...adapter=new recyclerViewadapter(lists,getContext()); recycler_view.setAdapter(adapter); 到此基本步骤已经完成
RecyclerView使用的适配器需要继承 RecyclerView.Adapter。...extends RecyclerView.Adapter { private Context mContext;...mOnItemClickLitener; public RecyclerViewAdapter(Context context, RecyclerViewAdapter.OnItemChatClickLitener...(view); } @Override public void onBindViewHolder(final RecyclerViewAdapter.MyViewHolder...rvAdapter = new RecyclerViewAdapter(this, new RecyclerViewAdapter.OnItemChatClickLitener() {
for (int i = 0; i < 20; i++) { titles.add("标题"+i); } recyclerView.setAdapter(new RecyclerViewAdapter...(this,titles)); } } RecyclerViewAdapter的代码： / ** * RecyclerView适配器 */ public class RecyclerViewAdapter...extends RecyclerView.Adapter<RecyclerViewAdapter.ViewHolder { private Context context; private...R.id.iv_icon); tvTitle = (TextView) itemView.findViewById(R.id.tv_title); } } public RecyclerViewAdapter
在写 MyItemTouchHelperCallback 之前我们先创建一个 IItemTouchHelperAdapter 接口，让 RecyclerViewAdapter 实现这个接口。...用于 RecyclerViewAdapter 回调。...的构造方法中传入 OnStartDragListener 的实例（即实现了该接口的Activity），给 item 左侧的按钮添加 事件监听 public class RecyclerViewAdapter...extends RecyclerView.Adapter<RecyclerViewAdapter.IItemViewHolder implements IItemTouchHelperAdapter...{ //构造方法 public RecyclerViewAdapter(List<ItemEntity list, OnStartDragListener mDragListener) {
android:text="content" android:textSize="12sp" /> 接下来就是创建适配器Adapter，新建RecyclerViewAdapter...类，继承RecyclerView.Adapter类，完成内部类 ViewHolder ，并重写以下3个主要方法，具体代码如下： package...extends RecyclerView.Adapter { private ArrayList mDatas...= null; private LayoutInflater mInflater = null; public RecyclerViewAdapter(Context context...简单修改一下自定义的RecyclerViewAdapter类中onBindViewHolder方法，使其产生一个随机的高度，代码如下： // 将数据与界面进行绑定的操作 @Override
recyclerView.setLayoutManager(new LinearLayoutManager(this, LinearLayoutManager.VERTICAL, false)); RecyclerViewAdapter...adapter = new RecyclerViewAdapter(); ItemTouchHelper helper = new ItemTouchHelper(new MyItemTouchCallback...ItemTouchHelper.Callback 接口： public class MyItemTouchCallback extends ItemTouchHelper.Callback { private final RecyclerViewAdapter...adapter; public MyItemTouchCallback(RecyclerViewAdapter adapter) { this.adapter = adapter
recyclerViewAdapter; @Override protected void onCreate(Bundle savedInstanceState) {...User>>() { @Override public void onChanged(List users) { recyclerViewAdapter.setDatas...(users); recyclerViewAdapter.notifyDataSetChanged(); } });...recyclerViewAdapter = new RecyclerViewAdapter(); activityMainBinding.recyclerview.setAdapter(...recyclerViewAdapter); activityMainBinding.recyclerview.setLayoutManager(new LinearLayoutManager
Footer View" android:textSize="20sp" android:gravity="center"/> 然后修改RecyclerViewAdapter...修改后的RecyclerViewAdapter代码如下： package com.jinyu.cqkxzsxy.android.advancedviewsample.adapter; import...java.util.ArrayList; /** * @创建者 鑫鱻 * @描述 Android零基础入门到精通系列教程 * 首发微信公众号分享达人秀（ShareExpert） */ public class RecyclerViewAdapter...mOnItemClickListener = null; private OnItemLongClickListener mOnItemLongClickListener = null; public RecyclerViewAdapter
recyclerViewAdapter = new RecyclerViewAdapter2(this, list); recyclerView.setAdapter(recyclerViewAdapter...if (i == a) { typeBean.setType(2); } list.add(typeBean); } recyclerViewAdapter.notifyDataSetChanged
在代码中设置一个普通的RecyclerView.adapter： ViewPager2 viewPager2=findViewById(R.id.viewpager2); RecyclerviewAdapter...adapter = new RecyclerviewAdapter(this); viewPager2.setAdapter(adapter); 这样竖直轮播图就大功告成了。
RecyclerView的滑动源码分析具体可参看 RecyclerView剖析 StickyHeader 关于开头gif图片的实现如下： 列表数据有50条，每5条为一组，adapter的实现 public class RecyclerViewAdapter...extends RecyclerView.Adapter { private Context mContext; private...List datas; public RecyclerViewAdapter(Context context) { this.mContext = context...public class TestDecoration extends RecyclerView.ItemDecoration { private RecyclerViewAdapter mAdapter...private final LongSparseArray mHeaderViews = new LongSparseArray(); public TestDecoration(RecyclerViewAdapter
1、recyclerView的基本使用使用recyclerView主要需要了解RecyclerViewAdapter、layoutManager。...重写recyclerViewAdapter的三个方法，onCreateViewHodler、onBindViewHolder、getItemCount。
. */ public class RecyclerViewAdapter extends RecyclerView.Adapter...{ private List datas; public RecyclerViewAdapter(List datas) { this.datas...databinding.ActivityMainBinding; public class MainActivity extends AppCompatActivity { private RecyclerViewAdapter...activityMainBinding = DataBindingUtil.setContentView(this, R.layout.activity_main); adapter = new RecyclerViewAdapter
return userInfoDao .getUserInfoList() .flowOn(Dispatchers.IO) } } 4.定义RecyclerViewAdapter
其实用的便是装饰者的模式 Android中的应用 装饰者模式在android的应用（举个栗子)，RecyclerView底部加载更多的的应用就可以用装饰者模式，RecyclerView适配器（RecyclerViewAdapter...）是被装饰者，底部加载更多适配器 （LoadMoreAdapterWrapper） 是装饰者，先来look一look代码块吧（装饰者与被装饰者需继承同一基类） RecyclerViewAdapter
比如你有个 RecyclerViewadapter 类会接收一个事件监听。
