Answer 1

I want to start Activity from Fragment1 how can I do this ?

You have this

public class Tab extends FragmentActivity in which case you can use the below unless you are starting activity from fragment class

 Intent intent = new Intent(Tab.this,Wallpaper.class);
 startActivity(intent);

Use the below in your fragment

  Intent intent = new Intent(getActivity(),Wallpaper.class);
  getActivtiy().startActivity(intent);  

getActivity

Return the Activity this fragment is currently associated with.
