i have also created a recyclerView clicklistener

recycler.setLayoutManager(new LinearLayoutManager(this));
recycler.addOnItemTouchListener(

#Override
public void onItemClick(View view, int position) {
// TODO Handle item click
Log.e("#####", "" + position);
switch (position)
{
case 0:
recycler.getFocusedChild();
Toast.makeText(getApplicationContext(), (CharSequence) recycler.getFocusedChild(),
Toast.LENGTH_SHORT).show();
break;
case 2:
Intent in=new Intent(getApplicationContext(),sample.class);
startActivity(in);
break;
case 7:
Toast.makeText(getApplicationContext(),"7",Toast.LENGTH_SHORT).show();
break;
}
}
})
);
recycler.setAdapter(adapter);
Expand you're bind method with a setOnClickListener.
public void bind(int position) {
name.setText(visibleItems.get(position).Text);
name.setOnClickListener(new View.OnClickListener()
#Override
public void onClick(View v) {
doSomething(visibleItems.get(position));
}
});
}
i have prepared an onclicklistener listview to put in a tab menu but after all done, i have noticed that such thing is not possible, i dont know may be with a small change to the code i can achieve what i need but my brain seriously stopped due to fraustrating:( :

i think what you need is navigation drawer
or you can use action bar

ListFragment will provide you with all what you need like ListActivity. You need to make a new Activity (Main Activity) extends FragmentActivity and make the ListFragment as a different class then add the Fragment to the Activity. If you don't know how to do this I strongly recommend you read The Fragments Tutorial Here.
I would like to know if and all If it is possible to call a list activity within an activity. I've spent the greater part of two days trying to make it work. But have fumbled over and over. Please help. Thanks in Advance.

Here is the whole fragment.
If Both classes Item and CustomAdapter reside in same java file then you need to remove public keyword from Item class.
Java only permits one public class on a .java file since Java designers chose a strict approach that enforces their idea of good design practices, and this is part of that theme.
For more information, check following link :

It looks like your:
public class Item
is outside your CustomAdapter class, move it inside CustomAdapter class, or make Item non public class.
Also, if you move it inside your CustomAdapter then consider making it static class. From your code you are not using enclosing class (here CustomAdapter) inside Item, so there is no need to make Item non static.
