I have list of contacts and i have show this list on RecyclerView using CardView.
List is showing perfectly But now I want to make clickable Card View. So that When I click on particular contact i will show details of particular contact.
When I click on particular CardView I Toast a message but can't find position of selected cardview and want to pass details of selected contact to another activity using intent.putExtra Method.
Code :
@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,ctx,contacts);
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());
holder.card_view.setOnClickListener(this);
}
@Override
public void onClick(View v) {
Toast.makeText(this.ctx, "Hello", Toast.LENGTH_SHORT).show();
Intent intent = new Intent(this.ctx,task_detail.class);
this.ctx.startActivity(intent);
}
@Override
public int getItemCount() {
return contacts.size();
}
public static class ContactViewHolder extends RecyclerView.ViewHolder {
TextView person_name, person_email;
ArrayList<Contact> contacts = new ArrayList<Contact>();
Context ctx;
CardView card_view;
public ContactViewHolder(View view, Context ctx ,ArrayList<Contact> contacts) {
super(view);
this.contacts=contacts;
this.ctx = ctx;
person_name = (TextView) view.findViewById(R.id.person_name);
person_email = (TextView) view.findViewById(R.id.person_email);
card_view = (CardView) view.findViewById(R.id.card_view);
}
}
Use the below code . Instead of using holder.card_view.setOnClickListener(this);
inside onBindViewHolder
, use it in ContactViewHolder
like this , card_view.setOnClickListener(this);
so that you can get the position using getPosition()
method.
public static class ContactViewHolder extends RecyclerView.ViewHolder implements View.OnClickListener {
TextView person_name, person_email;
ArrayList<Contact> contacts = new ArrayList<Contact>();
Context ctx;
CardView card_view;
public ContactViewHolder(View view, Context ctx ,ArrayList<Contact> contacts) {
super(view);
this.contacts=contacts;
this.ctx = ctx;
person_name = (TextView) view.findViewById(R.id.person_name);
person_email = (TextView) view.findViewById(R.id.person_email);
card_view = (CardView) view.findViewById(R.id.card_view);
card_view.setOnClickListener(this);
}
@Override
public void onClick(View v)
{
Toast.makeText(this.ctx, "position "+getPosition(), Toast.LENGTH_SHORT).show();
Intent intent = new Intent(this.ctx,task_detail.class);
this.ctx.startActivity(intent);
}
}
