if( item.getItemId() == R.id.senddata){

Bundle b= new Bundle();
b.putStringArray("key", selected);
intent=new Intent(this, f2.class);
intent.putExtras(b);



startActivity(intent);
//Toast.makeText(getApplicationContext(), selected[0]+selected[1]+selected[2]+selected[3]+selected[4], Toast.LENGTH_SHORT).show();
}

return super.onOptionsItemSelected(item);
}
