【中文标题】如何在回收站视图上添加 OnItemClick 侦听器 [重复]【英文标题】：How to add OnItemClick Listener on recycler view [duplicate] 【发布时间】：2018-03-08 11:26:43 【问题描述】：我在片段中使用了 recycleView，我想将 itemClickListener 添加到它。 这是我的代码：
MyAdapter.java：
public class MyAdapter extends RecyclerView.Adapter<MyAdapter.MyViewHolder>
private String[] mDataset;
public static class MyViewHolder extends RecyclerView.ViewHolder
public CardView mCardView;
public TextView mTextView;
public MyViewHolder(View v)
super(v);
mCardView = (CardView) v.findViewById(R.id.card_view);
mTextView = (TextView) v.findViewById(R.id.tv_text);
public MyAdapter(String[] myDataset)
mDataset = myDataset;
@Override
public MyAdapter.MyViewHolder onCreateViewHolder(ViewGroup parent, int viewType)
View v = LayoutInflater.from(parent.getContext()).inflate(R.layout.card_item, parent, false);
MyViewHolder vh = new MyViewHolder(v);
return vh;
@Override
public void onBindViewHolder(MyViewHolder holder, final int position)
holder.mTextView.setText(mDataset[position]);
@Override
public int getItemCount() return mDataset.length;
这是我在片段中调用它的时候，Staf3Fragment.java
/**
* A simple @link Fragment subclass.
* Activities that contain this fragment must implement the
* @link Staf3Fragment.OnFragmentInteractionListener interface
* to handle interaction events.
* Use the @link Staf3Fragment#newInstance factory method to
* create an instance of this fragment.
*/
public class Staf3Fragment extends Fragment
// TODO: Rename parameter arguments, choose names that match
// the fragment initialization parameters, e.g. ARG_ITEM_NUMBER
private static final String ARG_PARAM1 = "param1";
private static final String ARG_PARAM2 = "param2";
// TODO: Rename and change types of parameters
private String mParam1;
private String mParam2;
private OnFragmentInteractionListener mListener;
public Staf3Fragment()
// Required empty public constructor
/**
* Use this factory method to create a new instance of
* this fragment using the provided parameters.
*
* @param param1 Parameter 1.
* @param param2 Parameter 2.
* @return A new instance of fragment Staf3Fragment.
*/
// TODO: Rename and change types and number of parameters
public static Staf3Fragment newInstance(String param1, String param2)
Staf3Fragment fragment = new Staf3Fragment();
Bundle args = new Bundle();
args.putString(ARG_PARAM1, param1);
args.putString(ARG_PARAM2, param2);
fragment.setArguments(args);
return fragment;
@Override
public void onCreate(Bundle savedInstanceState)
super.onCreate(savedInstanceState);
if (getArguments() != null)
mParam1 = getArguments().getString(ARG_PARAM1);
mParam2 = getArguments().getString(ARG_PARAM2);
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState)
// Inflate the layout for this fragment
View view = inflater.inflate(R.layout.fragment_staf3, container, false);
RecyclerView rv = (RecyclerView) view.findViewById(R.id.rv_recycler_view);
rv.setHasFixedSize(true);
MyAdapter adapter = new MyAdapter(new String[]"Upacara Bendera", "Info Aplikasi");
rv.setAdapter(adapter);
LinearLayoutManager llm = new LinearLayoutManager(getActivity());
rv.setLayoutManager(llm);
return view;
// TODO: Rename method, update argument and hook method into UI event
public void onButtonPressed(Uri uri)
if (mListener != null)
mListener.onFragmentInteraction(uri);
@Override
public void onAttach(Context context)
super.onAttach(context);
if (context instanceof OnFragmentInteractionListener)
mListener = (OnFragmentInteractionListener) context;
else
//throw new RuntimeException(context.toString()
//+ " must implement OnFragmentInteractionListener");
@Override
public void onDetach()
super.onDetach();
mListener = null;
/**
* This interface must be implemented by activities that contain this
* fragment to allow an interaction in this fragment to be communicated
* to the activity and potentially other fragments contained in that
* activity.

*/
public interface OnFragmentInteractionListener
// TODO: Update argument type and name
void onFragmentInteraction(Uri uri);
如何在项目上点击不同的用途，我的意思是当点击项目 1 时它将转到另一个活动，如果项目 2 将转到另一个活动
请帮帮我 谢谢

【问题讨论】：
点击监听器不适用于 recyclerview。对于 recyclerview，您必须使用触摸监听器 怎么做？ 有很多相同的教程。如果您想检测对整行的点击，那么有一种简单的方法。您可以为该行的父布局添加点击监听器并为其添加一个点击监听器。 【参考方案1】：像这样创建一个自定义接口类
public interface ClickInterface
public void recyclerviewOnClick(int position);
在你的 Fragment 中实现它并初始化接口
YourFragment extends Fragment implements ClickInterface
private ClickInterface listner;
------- Your oncreateView --------
listner=this; //Now pass this in your adapter
在你的适配器构造函数中像这样获取这个监听器
public MyAdapter(String[] myDataset,ClickInterface listner)
this.mDataset = myDataset;
this.listner=listner;
最后在你的 ViewHolder 中
public class MyViewHolder extends RecyclerView.ViewHolder
public CardView mCardView;
public TextView mTextView;
public MyViewHolder(View v)
super(v);
mCardView = (CardView) v.findViewById(R.id.card_view);
mTextView = (TextView) v.findViewById(R.id.tv_text);
mTextView.setOnClickListener(new View.OnClickListener()
@Override
public void onClick(View view)
listner.recyclerviewOnClick(getAdapterPosition());
);
现在您将获得片段中的位置
public void recyclerviewOnClick(int position)
// Here you will get the position
【讨论】：
错误：(27, 21) 错误：无法从静态上下文引用非静态变量列表器 从你的viewholder类中移除静态关键字 现在我找不到符号 blockuserOnClick(int) 将其更改为 recyclerviewOnClick...检查我的编辑 得到这个错误，MyAdappter 类中的构造函数 MyAdapter 不能用于提供类型；必需：字符串 []，单击界面。找到：字符串[]【参考方案2】：你可以试试ButterKnifeLib@onClick()的方式。
@OnClick(R.id.btnCheck)
public void onCheck()
Log.d("ViewHolder", "position ->" + getAdapterPosition());
【讨论】：
【参考方案3】：你可以通过下面的代码做到这一点；
public class MyAdapter extends RecyclerView.Adapter<MyAdapter.MyViewHolder>
private String[] mDataset;
public static class MyViewHolder extends RecyclerView.ViewHolder
public CardView mCardView;
public TextView mTextView;
public View mainView;
public MyViewHolder(View v)
super(v);
mainView = v;
mCardView = (CardView) v.findViewById(R.id.card_view);
mTextView = (TextView) v.findViewById(R.id.tv_text);
public MyAdapter(String[] myDataset)
mDataset = myDataset;
@Override
public MyAdapter.MyViewHolder onCreateViewHolder(ViewGroup parent, int viewType)
View v = LayoutInflater.from(parent.getContext()).inflate(R.layout.card_item, parent, false);
MyViewHolder vh = new MyViewHolder(v);
return vh;
@Override
public void onBindViewHolder(MyViewHolder holder, final int position)
holder.mTextView.setText(mDataset[position]);
//And below code will execute item click event for RecyclerView's item....
holder.mainView.setOnClickListener(new View.OnClickListener()
@Override
public void onClick(View v)
//Do your code here for item click ....
);
@Override
public int getItemCount() return mDataset.length;
【讨论】：
【参考方案4】：像这样将你的 clickListenr 添加到 viewHolder
public class MyViewHolder extends RecyclerView.ViewHolder implements View.OnClickListener
public CardView mCardView;
public TextView mTextView;
public MyViewHolder(View v)
super(v);
mCardView = (CardView) v.findViewById(R.id.card_view);
mTextView = (TextView) v.findViewById(R.id.tv_text);
mCardView.setOnClickListener(this);
mTextView.setOnClickListener(this);
@Override
public void onClick(View view)
switch (view.getId())
case R.id.card_view:
//Action when card_view is clicked
break;
case R.id.tv_text:
//Action when tv_text is clicked
break;
default:
break;

错误:(25, 9) 错误：方法没有覆盖或实现超类型“@Override”中的方法 什么？这是工作代码...发布错误日志 我尝试添加 toast 以防 card_view 并且据说没有找到适合 makeText(view,string,int) 方法 toast.maketext 等的方法... 你的吐司应该是这样的 Toast.makeText(view.getContext(),"Sample",Toast.LENGTH_LONG)..那代码可以工作兄弟..它在工作室测试 如何制作不同的吐司？ item 1 显示 toast 点击 item 1， item 2 显示 tiast 点击 item 2【参考方案5】：您可以在适配器类中设置点击监听器，也可以使用 RecyclerView 点击监听器类。 如果您使用 RecyclerView 自定义单击，则必须使用此类并在需要的任何地方在活动或片段中使用此侦听器。这是类，你必须保留在 util 包中。
public class RecyclerOnClickListener implements RecyclerView.OnItemTouchListener
private OnItemClickListener mListener;
public interface OnItemClickListener
public void onItemClick(View view, int position);
public void onLongItemClick(View view, int position);
GestureDetector mGestureDetector;
public RecyclerOnClickListener(Context context, final RecyclerView recyclerView, OnItemClickListener listener)
mListener = listener;
mGestureDetector = new GestureDetector(context, new GestureDetector.SimpleOnGestureListener()
@Override
public boolean onSingleTapUp(MotionEvent e)
return true;
@Override
public void onLongPress(MotionEvent e)
View child = recyclerView.findChildViewUnder(e.getX(), e.getY());
if (child != null && mListener != null)
mListener.onLongItemClick(child, recyclerView.getChildAdapterPosition(child));
);
@Override
public boolean onInterceptTouchEvent(RecyclerView view, MotionEvent e)
View childView = view.findChildViewUnder(e.getX(), e.getY());
if (childView != null && mListener != null && mGestureDetector.onTouchEvent(e))
mListener.onItemClick(childView, view.getChildAdapterPosition(childView));
return true;
return false;
@Override
public void onTouchEvent(RecyclerView view, MotionEvent motionEvent)
@Override
public void onRequestDisallowInterceptTouchEvent (boolean disallowIntercept)
然后，你可以通过调用这样的方法来使用这个类，这里是代码。
private void recycleClick()
product_recycleview.addOnItemTouchListener(
new RecyclerOnClickListener(ProductListActivity.this, product_recycleview, new RecyclerOnClickListener.OnItemClickListener() @Override
public void onItemClick(View view, int position)
Intent intent = new Intent(ProductListActivity.this, ProductDetailsActivity.class); intent.putExtra("data", detailList.get(position));
startActivity(intent);
overridePendingTransition(R.anim.slide_in_left, R.anim.fade_out);
@Override
public void onLongItemClick(View view, int position)
));
您可以通过意图将数据发送到下一个活动，另一个解决方案是，您可以在 ViewHolder 类的项目上实现点击监听器，您可以像这样在适配器类中管理点击，下面的代码
itemRowHolder.lnr_layout_package.setOnClickListener(new View.OnClickListener()
@Override
public void onClick(View v)
Intent intent = new Intent(mContext, SinglePackageShowOnlyActivity.class);
intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK | Intent.FLAG_ACTIVITY_MULTIPLE_TASK);
intent.putExtra("list", dataList.get(i).getSingleItemModels());
intent.putExtra("title", model.getType());
intent.putExtra("image", model.getImages());
intent.putExtra("service_name", service_title);
intent.putExtra("pack_name",package_title);
mContext.getApplicationContext().startActivity(intent);
);
请记住，如果您可以在单个项目上设置点击，那么您必须更喜欢在适配器类中点击，如果您可以在适配器内设置单独的点击监听器，那么您必须将其放入 onBindView 类中
