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Staf3Fragment.java
中调用它的时候/**
* 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

public class Staf3Fragment extends Fragment {

private String mParam2;
private OnFragmentInteractionListener mListener;
public Staf3Fragment() {
// Required empty public constructor
}

// 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

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) {

如何点击项目点击不同用途，我的意思是当点击第1项时它将转到另一个活动，如果第2项将转到另一个活动

创建一个像这样的自定义接口类
public interface ClickInterface {
public void recyclerviewOnClick(int position);
}
在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
}
在适配器构造函数中获取此列表器
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
中片段中的位置public void recyclerviewOnClick(int position){
// Here you will get the position
}

您可以尝试使用ButterKnife Lib @onClick()方式。
@OnClick(R.id.btnCheck)
public void onCheck() {
Log.d("ViewHolder", "position ->" + getAdapterPosition());
}
答案 2 :(得分：0)
您可以通过以下代码执行此操作;
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; }
}

将clickListenr添加到viewHolder中，如下所示
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;
}
}
}

您可以在适配器类中设置单击侦听器，也可以使用RecyclerView单击侦听器类。 如果使用RecyclerView自定义单击，则必须使用此类，并在活动或片段中的任何位置使用此侦听器。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){}
}
之后，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) {
}
}));
}
你可以通过意图发送数据到下一个活动，另一个解决方案就是这个，你可以在ViewHolder类的项目上实现点击监听器，你可以像这样管理点击内部的适配器类，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，如果您可以设置单击某个项目，那么您必须更喜欢单击适配器类，如果您可以在适配器中设置单独的单击侦听器，那么您必须将其放入onBindView类
