android- How do I launch an Activity from a item in Reyclerview? - android-fragments

Question

I am trying to launch an activity from a recyclerview's item using OnClick method. I made an interface and used getAdapterPostion in the adapter. But the Activity is not launching. Here's my code:
Interface that I created in my Adapter:
public interface Clicklistener{
public void itemClicked(View view,int position);
}
}
Setter method for ClickListener:
public void setclickListener(Clicklistener clickListener){
this.clickListener = clickListener;
}
View Holder Method where I set the OnClickListener:
public class ViewHolderListMovies extends RecyclerView.ViewHolder implements View.OnClickListener {
private ImageView movieThumbnail;
private TextView movieTitle;
private TextView movieYear;
public ViewHolderListMovies(View itemView) {
super(itemView);
itemView.setOnClickListener(this);
movieThumbnail = (ImageView) itemView.findViewById(R.id.video_poster);
movieTitle = (TextView) itemView.findViewById(R.id.video_name);
movieYear = (TextView) itemView.findViewById(R.id.video_year);
}
#Override
public void onClick(View v) {
if(clickListener!=null){
clickListener.itemClicked(v,getAdapterPosition());
}
}
The I Initialised the the interface in the fragment:
listMoviesAdapter.setclickListener(this);
At last I started an intent in in the fragment to call the needed Activity:
#Override
public void itemClicked(View view, int position) {
startActivity(new Intent(getActivity(),MovieDetailsActivity.class));
}
Any Help is appreciated. Thanks!

Initialise the setoncliklistener in method onBindViewHolder. Example, may be help
public class HistoryAdapter extends RecyclerView.Adapter<HistoryAdapter.ViewHolder> {
private Context mContext;
private List<String> mDataSet;
private List<String> mIdevent;
public HistoryAdapter(Context context, List<String> dataSet, List<String> idevent, List<String> askPrice,
List<String> bidPrice, List<String> Profit) {
mContext = context;
mDataSet = dataSet;
mIdevent = idevent;
}
#Override
public ViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
View v = LayoutInflater.from(mContext)
.inflate(R.layout.layout_list_history, parent, false);
return new ViewHolder(v);
}
#Override
public void onBindViewHolder(ViewHolder holder, int position) {
Picasso.with(mContext).load(R.drawable.add2new).into(holder.image);
holder.text.setText(mDataSet.get(position));
holder.setClickListener(new HistoryAdapter.ViewHolder.ClickListener() {
public void onClick(View v, int pos, boolean isLongClick) {
if (isLongClick) {
// View v at position pos is long-clicked.
String poslx = pos + "";
String menax = mDataSet.get(pos);
Toast.makeText(mContext, "longclick pos. " + poslx + " pair " + menax, Toast.LENGTH_SHORT).show();
} else {
// View v at position pos is clicked.
//String possx = pos + "";
String poslx = pos + "";
String event2 = mDataSet.get(pos);
String id2 = mIdevent.get(pos);
Toast.makeText(mContext, "shortclick pos. " + poslx + " pair " + event2, Toast.LENGTH_SHORT).show();
//toggleSelection(pos);
Intent i = new Intent(mContext, HistoryCandlesActivity.class);
Bundle extras = new Bundle();
extras.putString("eventx", event2);
extras.putString("idx", id2);
extras.putInt("whatspage", 0);
i.putExtras(extras);
v.getContext().startActivity(i);
}
}
});
}
#Override
public int getItemCount() {
return mDataSet.size();
}
public void remove(int position) {
mDataSet.remove(position);
notifyItemRemoved(position);
}
public void add(String text, int position) {
mDataSet.add(position, text);
notifyItemInserted(position);
}
static class ViewHolder extends RecyclerView.ViewHolder implements View.OnClickListener, View.OnLongClickListener {
public ImageView image;
public TextView text;
private ClickListener clickListener;
public ViewHolder(View itemView) {
super(itemView);
image = (ImageView) itemView.findViewById(R.id.image);
text = (TextView) itemView.findViewById(R.id.text);
// We set listeners to the whole item view, but we could also
// specify listeners for the title or the icon.
itemView.setOnClickListener(this);
itemView.setOnLongClickListener(this);
}
/* Interface for handling clicks - both normal and long ones. */
public interface ClickListener {
/**
* Called when the view is clicked.
*
* #param v view that is clicked
* #param position of the clicked item
* #param isLongClick true if long click, false otherwise
*/
public void onClick(View v, int position, boolean isLongClick);
}
/* Setter for listener. */
public void setClickListener(ClickListener clickListener) {
this.clickListener = clickListener;
}
#Override
public void onClick(View v) {
// If not long clicked, pass last variable as false.
clickListener.onClick(v, getPosition(), false);
}
#Override
public boolean onLongClick(View v) {
// If long clicked, passed last variable as true.
clickListener.onClick(v, getPosition(), true);
return true;
}
}
}
