Android RecyclerView onClickListeners Item Click Listeners
Example
To implement an item click listener and/or an item long click listener, you can create an interface in your adapter:
public class CustomAdapter extends RecyclerView.Adapter<CustomAdapter.ViewHolder> {
public interface OnItemClickListener {
void onItemSeleted(int position, View view, CustomObject object);
}
public interface OnItemLongClickListener {
boolean onItemSelected(int position, View view, CustomObject object);
}
public final class ViewHolder extends RecyclerView.ViewHolder {
public ViewHolder(View itemView) {
super(itemView);
final int position = getAdapterPosition();
itemView.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View view) {
if(mOnItemClickListener != null) {
mOnItemClickListener.onItemSeleted(position, view, mDataSet.get(position));
}
}
});
itemView.setOnLongClickListener(new View.OnLongClickListener() {
@Override
public boolean onLongClick(View view) {
if(mOnItemLongClickListener != null) {
return mOnItemLongClickListener.onItemSelected(position, view, mDataSet.get(position));
}
}
});
}
}
private List<CustomObject> mDataSet;
private OnItemClickListener mOnItemClickListener;
private OnItemLongClickListener mOnItemLongClickListener;
public CustomAdapter(List<CustomObject> dataSet) {
mDataSet = dataSet;
}
@Override
public CustomAdapter.ViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
View view = LayoutInflater.from(parent.getContext())
.inflate(R.layout.view_item_custom, parent, false);
return new ViewHolder(view);
}
@Override
public void onBindViewHolder(CustomAdapter.ViewHolder holder, int position) {
// Bind views
}
@Override
public int getItemCount() {
return mDataSet.size();
}
public void setOnItemClickListener(OnItemClickListener listener) {
mOnItemClickListener = listener;
}
public void setOnItemLongClickListener(OnItemLongClickListener listener) {
mOnItemLongClickListener = listener;
}
}
Then you can set your click listeners after you create an instance of the adapter:
customAdapter.setOnItemClickListener(new CustomAdapter.OnItemClickListener {
@Override
public void onItemSelected(int position, View view, CustomObject object) {
// Your implementation here
}
});
customAdapter.setOnItemLongClickListener(new CustomAdapter.OnItemLongClickListener {
@Override
public boolean onItemSelected(int position, View view, CustomObject object) {
// Your implementation here
return true;
}
});
