我在一個片段中使用了一個recycleView，並且希望爲其添加itemClickListener。 這裏是我的代碼：如何在回收站視圖中添加OnItemClick監聽器
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; }
}
，這是當我在片段叫它，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;
}

public interface OnFragmentInteractionListener {

如何使項目點擊不同的使用，我意思是當點擊物品1時它會轉到另一個活動，如果物品2將轉到另一個活動
請幫我 謝謝

點擊監聽器不能用於recyclerview.For recyclerview你必須使用觸摸監聽器 –
如何做到這一點？ –
還有很多相同的教程。如果你想檢測點擊整個行比有一個簡單的方法。您可以爲該行的父級佈局添加單擊偵聽器，併爲其添加一個單擊偵聽器。 –
