I show list of data in card view successfully but now i want to open another activity and show details of clicked data.
I have three class MainActivity, ContactAdapter, Contact.
Main Activity Code:
RecyclerView recyclerView;
RecyclerView.Adapter adapter;
RecyclerView.LayoutManager layoutManager;
String[] name,email;
ArrayList<Contact> list = new ArrayList<Contact>();
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar);
setSupportActionBar(toolbar);
name = getResources().getStringArray(R.array.person_name);
email = getResources().getStringArray(R.array.person_email);
int count = 0;
for (String Name : name)
{
Contact contact = new Contact(Name,email[count]);
count++;
list.add(contact);
}
recyclerView= (RecyclerView) findViewById(R.id.recycler_view);
layoutManager = new LinearLayoutManager(this);
recyclerView.setLayoutManager(layoutManager);
recyclerView.setHasFixedSize(true);
adapter=new ContactAdapter(list);
recyclerView.setAdapter(adapter);
i tried but it's not working.
Adapter Code:
public class ContactAdapter extends RecyclerView.Adapter<ContactAdapter.ContactViewHolder> {
ArrayList<Contact> contacts = new ArrayList<Contact>();
public ContactAdapter(ArrayList<Contact> contacts) {
this.contacts = contacts;
}
#Override
public ContactViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
View view = LayoutInflater.from(parent.getContext()).inflate(R.layout.card_view_layout, parent, false);
ContactViewHolder contactViewHolder = new ContactViewHolder(view);
return contactViewHolder;
}
#Override
public void onBindViewHolder(ContactViewHolder holder, int position) {
Contact CON = contacts.get(position);
holder.person_name.setText(CON.getName());
holder.person_email.setText(CON.getEmail());
}
#Override
public int getItemCount() {
return contacts.size();
}
public static class ContactViewHolder extends RecyclerView.ViewHolder {
TextView person_name, person_email;
public ContactViewHolder(View view) {
super(view);
person_name = (TextView) view.findViewById(R.id.person_name);
person_email = (TextView) view.findViewById(R.id.person_email);
view.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
Toast.makeText(v.getContext(), "OnClick Version :",
Toast.LENGTH_SHORT).show();
}
});
view.setOnLongClickListener(new View.OnLongClickListener() {
#Override
public boolean onLongClick(View v) {
Toast.makeText(v.getContext(), "OnLongClick Version :",
Toast.LENGTH_SHORT).show();
return true;
}
});
}
}
}
In your adapter do this:
public class ProdutoAdapter extends RecyclerView.Adapter<ProdutoAdapter.ProdutoViewHolder>{
private static ProdutoAdapter.ClickListener clickListener; //this is important
private List<Produto> produtos; //this is my list of beans
public ProdutoAdapter(List<Produto> produtos) {
this.produtos = produtos;
}
#Override
public ProdutoViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
View v = LayoutInflater.from(parent.getContext()).inflate(R.layout.cardview_produtos, parent, false);
ProdutoViewHolder mvh = new ProdutoViewHolder(v);
return mvh;
}
#Override
public void onBindViewHolder(ProdutoViewHolder holder, int position) {
//holder.nome.setText(this.produtos.get(position).getNome());
holder.img.setImageDrawable(produtos.get(position).getImgDrawable());
holder.nome.setText(produtos.get(position).getNome());
holder.preco.setText(String.valueOf(produtos.get(position).getPreco()));
}
#Override
public int getItemCount() {
return this.produtos.size();
}
#Override
public void onAttachedToRecyclerView(RecyclerView recyclerView) {
super.onAttachedToRecyclerView(recyclerView);
}
public static class ProdutoViewHolder extends RecyclerView.ViewHolder implements View.OnClickListener, View.OnLongClickListener{
Produto produto;
CardView cardView;
TextView nome;
TextView preco;
ImageView img;
ProdutoViewHolder(View itemView) {
super(itemView);
itemView.setOnClickListener(this);
itemView.setOnLongClickListener(this);
cardView = (CardView) itemView.findViewById(R.id.cardviewProduto);
nome = (TextView) itemView.findViewById(R.id.nome);
preco = (TextView) itemView.findViewById(R.id.preco);
img = (ImageView) itemView.findViewById(R.id.foto);
}
public void setItem(Produto produto){
this.produto = produto;
}
public Produto getItem(){
return this.produto;
}
//this is what you'll need in your activity
#Override
public void onClick(View v) {
clickListener.onItemClick(getAdapterPosition(), v);
}
#Override
public boolean onLongClick(View v) {
clickListener.onItemLongClick(getAdapterPosition(), v);
return false;
}
}
public void setOnItemClickListener(ClickListener clickListener){
ProdutoAdapter.clickListener = clickListener;
}
public interface ClickListener {
void onItemClick(int position, View v);
void onItemLongClick(int position, View v);
}
}
and in your activity:
public static ProdutoAdapter mAdapter;
myActivity.mAdapter.setOnItemClickListener(new ProdutoAdapter.ClickListener() {
#Override
public void onItemClick(int position, View v) {
//do what you want
}
#Override
public void onItemLongClick(int position, View v) {
}
});
myActivity.mRecyclerView.setAdapter(mAdapter);

This picture shows the problem.
I am using nested RecyclerView right now.
What I want is that when the ADD button of the outer RecyclerView is pressed, the item of the inner RecyclerView is added.
But what I made is that no matter which button is pressed, the last added inner RecyclerView's item is added.
How can I add items each the proper RecyclerView position?
This is my code.

public class RoutineModel {
String routine;
public RoutineModel(String routine) {
this.routine = routine;

detailAdapter in RoutineAdapter gets re-assigned every time onCreateViewHolder gets called meaning it will always point to the RoutineDetailAdapter of the last item created in the RecyclerView.
A fix for this could be to pass the RoutineDetailAdapter of the clicked item with the click listener interface.
public class RoutineAdapter extends RecyclerView.Adapter<RoutineAdapter.ViewHolder> {
Context context;
ArrayList<RoutineModel> routineItems = new ArrayList<>();
OnRoutineItemClickListener listener;
public void setOnRoutineClickListener(OnRoutineItemClickListener listener) {
this.listener = listener;

routineItems.add(item);

public void addDetailItem(RoutineDetailAdapter routineDetailAdapter) {
routineDetailAdapter.addItem(new RoutineDetailModel());

I have converted a RecyclerView from Activity to Fragment all work but when i click on item i have this error:
java.lang.NullPointerException: Attempt to invoke interface method 'void fragment.MyRecyclerViewAdapter$MyClickListener.onItemClick(int, android.view.View)' on a null object reference
This error is in myClickListener.onItemClick(getAdapterPosition(), v);
public class MyRecyclerViewAdapter extends RecyclerView
.Adapter<MyRecyclerViewAdapter
.DataObjectHolder> {
private static String LOG_TAG = "MyRecyclerViewAdapter";
private ArrayList<DataObject> mDataset;
private static MyClickListener myClickListener;
public static class DataObjectHolder extends RecyclerView.ViewHolder
implements View
.OnClickListener {
TextView label;
TextView dateTime;
public DataObjectHolder(View itemView) {
super(itemView);
label = (TextView) itemView.findViewById(R.id.textView);
dateTime = (TextView) itemView.findViewById(R.id.textView2);
Log.i(LOG_TAG, "Adding Listener");
itemView.setOnClickListener(this);
}
#Override
public void onClick(View v) {
myClickListener.onItemClick(getAdapterPosition(), v); //ERROR HERE
}
}
public void setOnItemClickListener(MyClickListener myClickListener) {
this.myClickListener = myClickListener;
}
public MyRecyclerViewAdapter(ArrayList<DataObject> myDataset) {
mDataset = myDataset;
}
#Override
public DataObjectHolder onCreateViewHolder(ViewGroup parent,
int viewType) {
View view = LayoutInflater.from(parent.getContext())
.inflate(R.layout.card_view_row, parent, false);
DataObjectHolder dataObjectHolder = new DataObjectHolder(view);
return dataObjectHolder;
}
#Override
public void onBindViewHolder(DataObjectHolder holder, int position) {
holder.label.setText(mDataset.get(position).getmText1());
holder.dateTime.setText(mDataset.get(position).getmText2());
}
public void addItem(DataObject dataObj, int index) {

notifyItemRemoved(index);
}
#Override
public int getItemCount() {

}
public interface MyClickListener {
public void onItemClick(int position, View v);
}
}
This code is in fragment:
mView = inflater.inflate(R.layout.fragment_two, container, false);
mRecyclerView = (RecyclerView) mView.findViewById(R.id.my_recycler_view);
mRecyclerView.setHasFixedSize(false);
mLayoutManager = new LinearLayoutManager(getContext());
mRecyclerView.setLayoutManager(mLayoutManager);
mAdapter = new MyRecyclerViewAdapter(getDataSet());
mRecyclerView.setAdapter(mAdapter);
return mView;
You are not calling
public void setOnItemClickListener(MyClickListener myClickListener) {
this.myClickListener = myClickListener;
}
from anywhere.
Call this method from your adapter or fragment. Or if you do not want right now, just add null check
#Override
public void onClick(View v) {
if (myClickListener!= null) {
myClickListener.onItemClick(getAdapterPosition(), v); //ERROR HERE
}
}
And add below code into Fragment class.
((MyRecyclerViewAdapter) mAdapter).setOnItemClickListener(new MyRecyclerViewAdapter.MyClickListener() {
#Override
public void onItemClick(int position, View v) {
// Implement your logic to do after clicking on any item.
}
});
Before calling the set adapter on your recyclerview call setOnItemClickListener
I have solved with:
((MyRecyclerViewAdapter) mAdapter).setOnItemClickListener(new MyRecyclerViewAdapter
.MyClickListener() {
#Override
public void onItemClick(int position, View v) {
Log.wtf("TEST", position);
}
});
I have created a RecyclerView Adapter but now i'm struggling to do the onClick to open new activity.
This is my RecyclerView Adapter class:
public class RecycleAdapter extends RecyclerView.Adapter<RecycleAdapter.ViewHolder> {
private ArrayList<HashMap<String, String>> mDataset;
Context ctx;
public RecycleAdapter(ArrayList<HashMap<String, String>> mDataset) {
this.mDataset = mDataset;
this.ctx = ctx;
}
#Override
public ViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
View v = LayoutInflater.from(parent.getContext()).inflate(R.layout.activity_procedure, parent, false);
return new ViewHolder(v);
}
#Override
public void onBindViewHolder(ViewHolder holder, int position) {
holder.getId().setText(mDataset.get(position).get("id"));
holder.getItemname().setText(mDataset.get(position).get("name"));
//holder.getIvImage().setBackground(mDataset.get(position).get("icon"));
}
#Override
public int getItemCount() {
return mDataset.size();
}
public class ViewHolder extends RecyclerView.ViewHolder implements View.OnClickListener {
private CardView cardView;
private TextView itemId;
private TextView tvName;
private ImageView ivImage;
public ViewHolder(View itemView) {
super(itemView);
itemView.setOnClickListener(this);
itemId = itemView.findViewById(R.id.tvProfileItemName);
tvName = itemView.findViewById(R.id.tvProfileItemAge);
ivImage = itemView.findViewById(R.id.imageView3);
}
public TextView getId() {
return itemId;
}
public TextView getItemname() {
return tvName;
}
public ImageView getIvImage() {
return ivImage;
}
#Override
public void onClick(View v) {
}
}
}
My Main Activity just display the data inside of a recycler view
#Override
protected void onPostExecute(Void result) {
super.onPostExecute(result);
ListAdapter adapter = new SimpleAdapter(MainActivity.this, contactList,
R.layout.list_item, new String[]{"id", "name", "icon"},
new int[]{R.id.id, R.id.name, R.id.icon});
mAdapter = new RecycleAdapter(contactList);
mRecyclerView.setAdapter(mAdapter);
}
use interface
in recycler view adapter class
public interface recClick{
void onClickRec(int p);
}
private recClick rc;
public void setRecClick(recClick rc){
this.rc = rc
}
in recycler view holder class
#Override
public void onClick(View v) {
rc.onClickRec(getAdapterPosition());
}
in MainActivity use Interface
class MainActivity implements AdapterClass.recClick{
mAdapter.setRecClick(this);
#Override
public onClickRec(int p)
{
// do someting
}
}
#Override
public void onBindViewHolder(ViewHolder holder, int position) {
final int pos =position;
holder.getId().setText(mDataset.get(position).get("id"));
holder.getItemname().setText(mDataset.get(position).get("name"));
//holder.getIvImage().setBackground(mDataset.get(position).get("icon"));
holder.cardView.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
Intent intent=new Intent(context,NewActivity.class);
intent.putExtra("yourValue", String.valueOf(mDataset.get(position).get(pos)));
ctx.startActivity(intent);
}
});
}
Remember to give reference to your cardview
cardView = (CardView)itemView.findViewById(R.id.cardview);
I am trying to pass view Id from Recyclerview Adapter to Activity,when the Recycler view List item is clicked.
public class Adapter extends RecyclerView.Adapter<Adapter.ViewHolder> implements FastScrollRecyclerView.SectionedAdapter{

List<User> dataSource;

public ActiveBeepsAdapter(List<User> dataArgs, OnRecyclerItemClickListener onRecyclerItemClickListener,Context context) {
this.dataSource = dataArgs;
this.onRecyclerItemClickListener = onRecyclerItemClickListener;
this.context = context;
}
#Override
public ViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
// create a new view
View view = LayoutInflater.from(parent.getContext()).inflate(R.layout.single_active_message, parent, false);
ViewHolder viewHolder = new ViewHolder(view, onRecyclerItemClickListener);
return viewHolder;
}
#Override
public void onBindViewHolder(ViewHolder holder, int position) {
User user = dataSource.get(position);
holder.tvId.setText(user.getId());
Picasso.with(context)
.load(user.getProfilePicUrl())
.placeholder(R.drawable.bg_logo)
.error(R.drawable.bg_logo)
.transform(new CircleTransform())
.into(holder.ivUserProfile);
}
#Override
public int getItemCount() {
return dataSource.size();
}
#NonNull
#Override
public String getSectionName(int i) {
return String.valueOf(dataSource.get(i).getId().charAt(0));
}
public class ViewHolder extends RecyclerView.ViewHolder implements View.OnClickListener {
private OnRecyclerItemClickListener onRecyclerItemClickListener;
User data = new User();
TextView tvId;
ImageView ivUserProfile;
public ViewHolder(View itemView, OnRecyclerItemClickListener onRecyclerItemClickListener) {
super(itemView);
this.onRecyclerItemClickListener = onRecyclerItemClickListener;
tvId = (TextView)itemView.findViewById(R.id.tvName);
ivUserProfile = (ImageView)itemView.findViewById(R.id.ivProfilePic);
}
#Override
public void onClick(View v) {
int position = getAdapterPosition();
User user = dataSource.get(position);
int id = v.getId();
onRecyclerItemClickListener.onRecyclerItemClick(user,id);
}
}
}
Suppose, If the Profile Image is clicked, the view id should sent to activity..
And My Activity
#EActivity
public class ActiveMessage extends AppCompatActivity implements Adapter.OnRecyclerItemClickListener{
#ViewById(R.id.toolbar)
Toolbar toolbar;
#ViewById(R.id.rvactiveMessage)
FastScrollRecyclerView rvmessage;
List<User> allUser;
#ViewById(R.id.toolbar_title)
TextView tv_toolbar;
#AfterViews
protected void init(){
toolbar.setNavigationIcon(getResources().getDrawable(R.drawable.ic_arrow_drop_down_black_24dp));
setSupportActionBar(toolbar);
getSupportActionBar().setDisplayHomeAsUpEnabled(true);
tv_toolbar.setText("Active Message");
toolbar.setNavigationOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
onBackPressed();
}
});
allUser = new ArrayList<>();
User user;
String fullName[] = {"ajay","kamal","akhil"};
String id[] = {"its_ajay","its_kamal","its_akhil"};
for(int i=0;i<id.length;i++){
user = new User();
user.setId(id[i]);
user.setFullName(fullName[i]);
allUser.add(user);
}
Adapter adapter = new Adapter(allUser,this,getApplicationContext());
rvmessage.setLayoutManager(new LinearLayoutManager(getApplicationContext()));
rvmessage.setAdapter(activeBeepsAdapter);
}
#Override
public void onRecyclerItemClick(User data,int id) {
if (!Utils.isNetworkAvailable(getApplicationContext())) {
noInternet();
}
// tvName has multiple Implementation
if (id == R.id.tvName){
Log.d("Id",data.getId());
}
}
public void noInternet(){
final Dialog dialog = new Dialog(this);
dialog.setContentView(R.layout.alert_dialog);
dialog.show();
}
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_active_message);
}
#Override
public void onBackPressed() {
super.onBackPressed();
finish();
}
}
In my Activity, If the ProfileImage is clicked, pop up the dialog box.
Also, i need to check if there is Internet Connection when the list Item is clicked.
In adapter onClick method instead of id pass view:
#Override
public void onClick(View v) {
int position = getAdapterPosition();
User user = dataSource.get(position);
int id = v.getId();
onRecyclerItemClickListener.onRecyclerItemClick(user,v);
}
Now in Activity
#Override
public void onRecyclerItemClick(User data,View view) {
if (!Utils.isNetworkAvailable(getApplicationContext())) {
noInternet();
}
// tvName has multiple Implementation
if (view.getId() == R.id.tvName){
Log.d("Id",data.getId());
}
}
I want to do different job for different RecycleView item. I created custom OnClickListener for RecycleView and using this from my activity. But problem is when I want to get RecycleView Item Id form OnClick it's return -1. I can't able to check view Id.
