RecyclerView onClick for multiple buttons and handling from Activity
here is the best way to achieve that:--
this is how i have implemented
public class FollowersDetailsAdapter extends RecyclerView.Adapter<FollowersDetailsAdapter.MyViewHolder> {
private List<GetUserFollowDetailsResponseData> followersList;
Context context;
public FollowersDetailsAdapterListener onClickListener;
public class MyViewHolder extends RecyclerView.ViewHolder {
public TextView rv_tv_follower_name, rv_tv_follower_desig;
public CircleImageView rv_iv_follower_image;
RelativeLayout rv_rel_layout_followers, rel_layout_followers;
LikeButton rv_iv_follower_icon;
public MyViewHolder(View view) {
super(view);
rv_rel_layout_followers = (RelativeLayout) view.findViewById(R.id.rv_rel_layout_followers);
rel_layout_followers = (RelativeLayout) view.findViewById(R.id.rel_layout_followers);
rv_iv_follower_image = (CircleImageView) view.findViewById(R.id.rv_iv_follower_image);
rv_tv_follower_name = (TextView) view.findViewById(R.id.rv_tv_follower_name);
rv_tv_follower_desig = (TextView) view.findViewById(R.id.rv_tv_follower_desig);
rv_iv_follower_icon = (LikeButton) view.findViewById(R.id.rv_iv_follower_icon);
rel_layout_followers.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
onClickListener.iconTextViewOnClick(v, getAdapterPosition());
}
});
}
}
public FollowersDetailsAdapter(List<GetUserFollowDetailsResponseData> FollowersList, FollowersDetailsAdapterListener listener) {
this.followersList = FollowersList;
this.onClickListener = listener;
}
@Override
public MyViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
View itemView = LayoutInflater.from(parent.getContext())
.inflate(R.layout.followers_list_row, parent, false);
return new MyViewHolder(itemView);
}
@Override
public void onBindViewHolder(final MyViewHolder holder, final int position) {
if (followersList.get(position).getImage() != null && !followersList.get(position).getImage().trim().equalsIgnoreCase("")) {
Picasso.with(context)
.load(followersList.get(position).getImage())
.resize(200, 200).into(holder.rv_iv_follower_image);
}
holder.rv_tv_follower_name.setText(followersList.get(position).getName());
holder.rv_tv_follower_desig.setText(followersList.get(position).getDescription());
if (followersList.get(holder.getAdapterPosition()).getID() == Integer.parseInt(ApplicationPreference.getUserId())) {
holder.rv_iv_follower_icon.setVisibility(View.GONE);
} else {
holder.rv_iv_follower_icon.setVisibility(View.VISIBLE);
if (followersList.get(position).getIsFollowing() == 0) {
holder.rv_iv_follower_icon.setLiked(false);
} else if (followersList.get(position).getIsFollowing() == 1) {
holder.rv_iv_follower_icon.setLiked(true);
}
}
holder.rv_iv_follower_icon.setOnLikeListener(new OnLikeListener() {
@Override
public void liked(LikeButton likeButton) {
onClickListener.iconImageViewOnClick(likeButton, position);
}
@Override
public void unLiked(LikeButton likeButton) {
onClickListener.iconImageUnFollowOnClick(likeButton, position);
}
});
}
public interface FollowersDetailsAdapterListener {
void iconTextViewOnClick(View v, int position);
void iconImageViewOnClick(View v, int position);
void iconImageUnFollowOnClick(View v, int position);
}
@Override
public int getItemCount() {
return followersList.size();
}
}
and in your activity where you initialize the adapter--
followersDetailsAdapter = new FollowersDetailsAdapter(followersList, new FollowersDetailsAdapter.FollowersDetailsAdapterListener() {
@Override
public void iconTextViewOnClick(View v, int position) {
gotoUserProfile(followersList.get(position).getID());
}
@Override
public void iconImageViewOnClick(View v, int position) {
followUserProfile(followersList.get(position).getID(),1);
}
@Override
public void iconImageUnFollowOnClick(View v, int position){
followUserProfile(followersList.get(position).getID(),0);
}
});
Here my solution if it could help someone.
You could click in one item of the recyclerview or one of the two buttons.
The interface implements:
onStudentItemClick, for click in the recyclerview item
onChatItemClick and onAbsenceItemClick for click the buttons
With
holder.imgChat.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View v) {
mOnClickListener.onChatItemClick(mStudents.get(index));
}
});
I set the click listener for one button
And in the class StudentViewHolder I implement OnClickListener and override onClik
@Override
public void onClick(View v) {
if (mOnClickListener != null){
int clickedPosition = getAdapterPosition();
mOnClickListener.onStudentItemClick(mStudents.get(clickedPosition));
}
}
Here the Adapter:
public class StudentsAdapter extends RecyclerView.Adapter<StudentsAdapter.StudentsViewHolder> {
private ListItemClickListener mOnClickListener;
private ArrayList<Student> mStudents;
public interface ListItemClickListener {
void onStudentItemClick(Student student);
void onChatItemClick(Student student);
void onAbsenceItemClick(Student student);
}
public StudentsAdapter(ArrayList<Student> students, ListItemClickListener listener) {
mStudents = students;
mOnClickListener = listener;
}
@Override
public StudentsViewHolder onCreateViewHolder(ViewGroup viewGroup, int viewType) {
Context context = viewGroup.getContext();
int layoutIdForListItem = R.layout.student_list_item;
LayoutInflater inflater = LayoutInflater.from(context);
boolean shouldAttachToParentImmediately = false;
View view = inflater.inflate(layoutIdForListItem, viewGroup, shouldAttachToParentImmediately);
StudentsViewHolder viewHolder = new StudentsViewHolder(view);
return viewHolder;
}
@Override
public void onBindViewHolder(StudentsViewHolder holder, int position) {
final Integer index = position;
holder.tvStudent.setText(mStudents.get(position).nameForList());
holder.imgChat.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View v) {
mOnClickListener.onChatItemClick(mStudents.get(index));
}
});
holder.imgAbsence.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View v) {
mOnClickListener.onAbsenceItemClick(mStudents.get(index));
}
});
}
public Student getItem(Integer position){
return mStudents.get(position);
}
@Override
public int getItemCount() {
return mStudents.size();
}
class StudentsViewHolder extends RecyclerView.ViewHolder
implements OnClickListener {
ImageView imgStudent;
TextView tvStudent;
ImageButton imgChat, imgAbsence;
public StudentsViewHolder(View itemView) {
super(itemView);
imgStudent = (ImageView) itemView.findViewById(R.id.img_student);
tvStudent = (TextView) itemView.findViewById(R.id.tv_student);
imgChat = (ImageButton) itemView.findViewById(R.id.btn_chat_student);
imgAbsence = (ImageButton) itemView.findViewById(R.id.btn_absence);
itemView.setOnClickListener(this);
}
@Override
public void onClick(View v) {
if (mOnClickListener != null){
int clickedPosition = getAdapterPosition();
mOnClickListener.onStudentItemClick(mStudents.get(clickedPosition));
}
}
}
}
Fragment the implement the interface:
public class SubjectDetailFragment extends Fragment implements StudentsAdapter.ListItemClickListener {
...
@Override
public void onStudentItemClick(Student student) {
StudentDetailFragment detailFragment = StudentDetailFragment.newInstance();
Bundle bundle = new Bundle();
bundle.putParcelable("student", student);
detailFragment.setArguments(bundle);
FragmentManager fragmentManager = getFragmentManager();
FragmentTransaction fragmentTransaction = fragmentManager.beginTransaction();
fragmentTransaction.replace(R.id.frame_layout, detailFragment);
fragmentTransaction.addToBackStack(null);
fragmentTransaction.commit();
}
@Override
public void onChatItemClick(Student student) {
...
}
@Override
public void onAbsenceItemClick(Student student) {
...
}
Please, try this principle to create a communication between activity, adapter through the interface, I hope this principle helps you:
Model Class:
public class YourModel {
private String firstName;
private String lastName;
public YourModel(String firstName, String lastName) {
this.firstName = firstName;
this.lastName = lastName;
}
//... setters & getters
}
Interface:
public interface AdapterCallback {
void onClickCallback(YourModel itemModel);
}
Adapter:
public class YourAdapter extends RecyclerView.Adapter<YourAdapter.ViewHolder> {
private List<YourModel> data;
private AdapterCallback callback;
private Context context;
public YourAdapter(List<YourModel> data, AdapterCallback callback) {
this.data = data;
this.callback = callback
}
@Override
public YourAdapter.ViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
context = parent.getContext();
LayoutInflater inflater = LayoutInflater.from(context);
View item = inflater.inflate(R.layout.item_recycler, parent, false);
return new ViewHolder(item);
}
@Override
public void onBindViewHolder(YourAdapter.ViewHolder holder, int position) {
YourModel itemModel = data.get(position);
String lastName = itemModel.getLastName();
String firstName = itemModel.getFirstName();
holder.tvFirstName.setText(firstName);
holder.tvLastName.setText(lastName);
holder.tvFirstName.setOnClickListener {
callback.onClickCallback(itemModel));
}
}
@Override
public int getItemCount() {
return data.size();
}
static class ViewHolder extends RecyclerView.ViewHolder {
private TextView tvFirstName;
private TextView tvLastName;
ViewHolder(View itemView) {
super(itemView);
tvFirstName = (TextView) itemView.findViewById(R.id.tv_first);
tvLastName = (TextView) itemView.findViewById(R.id.tv_last);
}
}
Activity:
public class MyActivity extends AppCompatActivity implements AdapterCallback {
private YourAdapter adapter;
private List<YourModel> items;
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
// 1. init your list && fill it with needed data
// 2. init your adapter
// 3. put your list as parameter into constructor + interface
items = new ArrayList<YourModel>()
items.add(YourModel("John", "Doe"));
items.add(YourModel("Bob", "Marley"));
adapter = new YourAdapter(items, this)
}
@Override
public void onClickCallback(YourModel itemModel) {
Toast.makeText(this, itemModel.getFirstName(), Toast.LENGTH_SHORT).show();
}
I think that this information is enough to understand what I mean. The same principle you can create multiple OnClick methods in your interface or put one onClick for a few buttons and check id or something else to get needed information that you need. Good luck
