【中文标题】如何使 RecyclerView 处理 onclicklistener [重复]【英文标题】：How To make RecyclerView handle onclicklistener [duplicate] 【发布时间】：2016-03-31 00:45:58 【问题描述】：有没有人使用 RecyclerView 找到一种方法来为 RecyclerView 中的项目设置 onClickListener？
这是我的代码：
Pasal_Bab.java
public class Pasal_Bab extends Fragment implements SearchView.OnQueryTextListener
private RecyclerViewEmptySupport rv;
private List<PasalBabModel> mPBH;
private PasalBabAdapter adapter;
private static ArrayList<PasalBabModel> people;
@Override
public void onCreate(Bundle savedInstanceState)

rv.setLayoutManager(layoutManager);
rv.setEmptyView(view.findViewById(R.id.empty));

String[] locales = Locale.getISOCountries();
mPBH = new ArrayList<>();
for (String countryCode : locales)
Locale obj = new Locale("Pasalxyz", countryCode);
mPBH.add(new PasalBabModel(obj.getDisplayCountry(), obj.getISO3Country()));
adapter = new PasalBabAdapter(mPBH);
rv.setAdapter(adapter);
@Override
public void onCreateOptionsMenu(Menu menu, MenuInflater inflater)
inflater.inflate(R.menu.menu_main, menu);
final MenuItem item = menu.findItem(R.id.action_search);
final SearchView searchView = (SearchView) MenuItemCompat.getActionView(item);
searchView.setOnQueryTextListener(this);
MenuItemCompat.setOnActionExpandListener(item,
new MenuItemCompat.OnActionExpandListener()
@Override
public boolean onMenuItemActionCollapse(MenuItem item)
// Do something when collapsed
adapter.setFilter(mPBH);
return true; // Return true to collapse action view
@Override
public boolean onMenuItemActionExpand(MenuItem item)
// Do something when expanded
return true; // Return true to expand action view
);
@Override
public boolean onQueryTextSubmit(String query)
return false;
@Override
public boolean onQueryTextChange(String newText)
final List<PasalBabModel> filteredModelList = filter(mPBH, newText);
adapter.animateTo(filteredModelList);
adapter.setFilter(filteredModelList);
rv.scrollToPosition(0);
return false;
private List<PasalBabModel> filter(List<PasalBabModel> models, String query)
query = query.toLowerCase();
final List<PasalBabModel> filteredModelList = new ArrayList<>();
for (PasalBabModel model : models)
final String text = model.getpasalbab_p().toLowerCase();
if (text.contains(query))
filteredModelList.add(model);
return filteredModelList;
PasalBabAdapter.java
public class PasalBabAdapter extends RecyclerView.Adapter<PasalBabVH>
private List<PasalBabModel> mPasalBabModel;
public PasalBabAdapter(List<PasalBabModel> mPasalBabModel)
this.mPasalBabModel = mPasalBabModel;
@Override
public void onBindViewHolder(PasalBabVH PasalBabVH, int i)
final PasalBabModel model = mPasalBabModel.get(i);
PasalBabVH.bind(model);
@Override

return new PasalBabVH(view);
public void setFilter(List<PasalBabModel> PasalBabModels)
mPasalBabModel = new ArrayList<>();
mPasalBabModel.addAll(PasalBabModels);
notifyDataSetChanged();
@Override
public int getItemCount()
return mPasalBabModel.size();
public void animateTo(List<PasalBabModel> models)
applyAndAnimateRemovals(models);
applyAndAnimateAdditions(models);
applyAndAnimateMovedItems(models);
private void applyAndAnimateRemovals(List<PasalBabModel> newModels)
for (int i = mPasalBabModel.size() - 1; i >= 0; i--)
final PasalBabModel model = mPasalBabModel.get(i);
if (!newModels.contains(model))

if (fromPosition >= 0 && fromPosition != toPosition)
moveItem(fromPosition, toPosition);
public PasalBabModel removeItem(int position)
final PasalBabModel model = mPasalBabModel.remove(position);
notifyItemRemoved(position);
return model;
public void addItem(int position, PasalBabModel model)

public void moveItem(int fromPosition, int toPosition)
final PasalBabModel model = mPasalBabModel.remove(fromPosition);
mPasalBabModel.add(toPosition, model);
notifyItemMoved(fromPosition, toPosition);
PasalBabVH.java
public class PasalBabVH extends RecyclerView.ViewHolder
public TextView p_TextView;
public TextView b_TextView;
public PasalBabVH(View itemView)
super(itemView);
p_TextView = (TextView) itemView.findViewById(R.id.uud_pasal);
b_TextView = (TextView) itemView.findViewById(R.id.uud_bab);
public void bind(PasalBabModel mx)
p_TextView.setText(mx.getpasalbab_p());
b_TextView.setText(mx.getpasalbab_b());
PasalBabModel.java
public class PasalBabModel
String pasalbab_p;
String pasalbab_b;
public PasalBabModel(String pasalbab_p, String pasalbab_b)
this.pasalbab_p = pasalbab_p;
this.pasalbab_b = pasalbab_b;
public String getpasalbab_p()
return pasalbab_p;
public String getpasalbab_b()
return pasalbab_b;
请帮助我...我是初学者:)
【问题讨论】：
浏览这个androidhive.info/2015/04/… 谢谢，但它不起作用 【参考方案1】：像这样创建适配器：
public class CustomAdapter extends RecyclerView.Adapter<Custom.ViewHolder>
private List<SomeObject> mDataSet;
public OnItemClickListener mItemClickListener;
private Context mContext;
public CustomAdapter(Context context, List<SomeObject> myDataset, OnItemClickListener mItemClickListener)
this.mDataSet = myDataset;
this.mItemClickListener = mItemClickListener;
this.mContext = context;
public void updateData(List<SomeObject> mDataSet)
this.mDataSet = mDataSet;
notifyDataSetChanged();
public void removeItem(int position)
mDataSet.remove(position);
notifyItemRemoved(position);
@Override
public ViewHolder onCreateViewHolder(ViewGroup parent, int viewType)
// create a new view
View v = LayoutInflater.from(parent.getContext()).inflate(R.layout.list_item, parent, false);
return new ViewHolder(v);
@Override
public void onBindViewHolder(final ViewHolder holder, int position)
// - get element from your dataset at this position
// - replace the contents of the view with that element
final SomeObject obj = mDataSet.get(position);
holder.name.setText(obj.getName());
@Override
public int getItemCount()
return mDataSet.size();
public class ViewHolder extends RecyclerView.ViewHolder implements View.OnClickListener, View.OnLongClickListener
TextView name;
public ViewHolder(View v)
super(v);
name = (TextView) v.findViewById(R.id.naam);
v.setOnClickListener(this);
v.setOnLongClickListener(this);
@Override
public void onClick(View v)
// If not long clicked, pass last variable as false.
mItemClickListener.onItemClick(v, getLayoutPosition(), false, mDataSet);
@Override
public boolean onLongClick(View v)
// If long clicked, passed last variable as true.
mItemClickListener.onItemClick(v, getLayoutPosition(), true, mDataSet);
return true;
public interface OnItemClickListener
void onItemClick(View view, int position, boolean isLongClick, List<SomeObject> mFilteredList);
并像这样设置适配器：
mAdapter = new CustomAdapter(getActivity(), dataSet, new CustomAdapter.OnItemClickListener()
@Override
public void onItemClick(View v, int position, boolean isLongClick, List<SomeObject> mDataSet)
if (isLongClick)
//Long click
SomeObject obj = mDataSet.get(position);
else
//Normal click
SomeObject obj = mDataSet.get(position);
);
【讨论】：
【参考方案2】：使用接口来处理 onClicks。
把这个放到适配器里：
public interface OnItemClickListener
void onClickItem(View view, int position);
public void SetOnItemClickListener(OnItemClickListener mItemClickListener)
this.mItemClickListener = mItemClickListener;
然后在视图持有者中执行此操作：
public class PasalBabVH extends RecyclerView.ViewHolder
public TextView p_TextView;
public TextView b_TextView;
public PasalBabVH(View itemView)
super(itemView);
p_TextView = (TextView) itemView.findViewById(R.id.uud_pasal);
b_TextView = (TextView) itemView.findViewById(R.id.uud_bab);
p_TextView.setOnClickListener(new View.OnClickListener()
@Override
public void onClick(View v)
if (mItemClickListener != null)
);
b_TextView.setOnClickListener(new View.OnClickListener()
@Override
public void onClick(View v)
if (mItemClickListener != null)
);
public void bind(PasalBabModel mx)
p_TextView.setText(mx.getpasalbab_p());
b_TextView.setText(mx.getpasalbab_b());
在片段中这样做：
adapter.SetOnItemClickListener(new PasalBabAdapter.OnItemClickListener()
@Override
public void onClickItem(View view, int position)
);
