Answer 1

I have a simple trick to it! This is the code in MainActivity:

Intent intent=new Intent(getApplicationContext(),Main2Activity.class);
        intent.putExtra("pos",1);
        startActivity(intent);

Intent intent1=new Intent(getApplicationContext(),Main2Activity.class);
        intent1.putExtra("pos",2);
        startActivity(intent1);

In Main2Activity which is a NavigationDrawer with fragments

Bundle extras;
  extras=getIntent().getExtras();
        if(extras!=null)
        {
            position=extras.getInt("pos");
            if(position==1)
            {
                fragment=new FragmentOne();

                if(fragment !=null)
                {
                    android.support.v4.app.FragmentManager fragmentManager=getSupportFragmentManager();
                    FragmentTransaction fragmentTransaction=fragmentManager.beginTransaction();
                    fragmentTransaction.replace(R.id.screen_area,fragment);
                    fragmentTransaction.commit();
                }
            }
            if(position==2)
            {
                fragment=new FragmentTwo();

                if(fragment !=null)
                {
                    android.support.v4.app.FragmentManager fragmentManager=getSupportFragmentManager();
                    FragmentTransaction fragmentTransaction=fragmentManager.beginTransaction();
                    fragmentTransaction.replace(R.id.screen_area,fragment);
                    fragmentTransaction.commit();
                }
            }
        }
