I am having a CustomRecyclerViewAdapter.class file in which I have implemented the below method.
public void onBindViewHolder(RecyclerViewHolder viewHolder, int position)
{
viewHolder.title.setText(mData.get(position).text);
//viewHolder.icon.setBackgroundColor(Color.parseColor(mData.get(position).color));
viewHolder.setClickListener(new RecyclerViewHolder.ClickListener(){
@Override
public void onClick(View v, int position, boolean isLongClick) {
if (isLongClick) {
// View v at position pos is long-clicked.
Toast.makeText(v.getContext(), "Hey you just hit item" + position, Toast.LENGTH_SHORT).show();
}else {
// View v at position pos is clicked.
//how to start a new activity here
Toast.makeText(v.getContext(),"Hey you just hit item" + position,Toast.LENGTH_SHORT).show();
}
}
});
}
So how i can start the new activity in the else block above.
Group.class
public class Group extends ActionBarActivity {
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);//line no. 16 which is indicated in logcat
setContentView(R.layout.group);
getSupportActionBar().setHomeButtonEnabled(true);
getSupportActionBar().setDisplayHomeAsUpEnabled(true);
}
This is my error logcat.....

Thanks for your time.
By default it have 5. you can increase as per your need. Save this answer.
onCreateViewHolder(parent: ViewGroup, viewType: Int) Parent is the ViewGroup into which the new View will be added after it is bound to an adapter position and viewType is the type of the new View. This method will return a new ViewHolder that holds a View of the given view type.
You can use any View to it. getContext() method provides almost activity methods because Activity extends Context.
v.getContext().startActivity(intent);
