Fragment

Replace fragment with another fragment

 FragmentManager fm = getSupportFragmentManager();
 FragmentTransaction ft = fm.beginTransaction();
 ft.replace(R.id.content, fragment, TAG);
 ft.addToBackStack(TAG);
 ft.commit();

Passing data between Fragments in the same Activity

Fragment A:

Bundle b = new Bundle();
b.putString("Key", "YourValue");
b.putInt("YourKey", 1);

FragmentB fragB = new FragmentB();
fragB.setArguments(b); 
getFragmentManager().beginTransaction().replace(R.id.your_container, fragB);

Fragment B:

Bundle b = this.getArguments();
if(b != null){
   int i = b.getInt("YourKey");
   String s =b.getString("Key");
}
