Answer 1

You can get the id of the View parameter then use that in your switch. Something like

 public void onClick(View v) {
       Intent n = null;
       int id = v.getId();
       switch (id){
           case R.id.someId:
                n = new Intent(getActivity(), FragMent1.class);
                break;
           case R.id.someOtherId:
                n = new Intent(getActivity(), FragMent2.class);
                break;
        }

It sounds like this is what you are looking for. If not, please explain a little better what you want.

Edit

I'm not sure that I understand your latest problem but if I do then you can do something like

public void onClick(View v) {
       Intent n = null;
       int id = v.getId();
       switch (id){
           case R.id.someId:
           case R.id.someOtherId:
                n = new Intent(getActivity(), FragMent1.class);
                break;

Answer 2

Fragment and Activity are difference.
Activity.startActivity(Intent) method call new Activity but FragMent1 is not Activity.
so you can't cast FragMent1 class to Activity class.
if FragMent1 inherit Fragment, you should use FragmentManager.

Fragment fragment = FragMent1();
FragmentTransaction ft = getFragmentManager().beginTransaction();
ft.replace(R.id.content, fragment);
ft.commit();

R.id.content is id of one of layout.

It just is simple example code. you should write the code depending your application.

public void onClick(View v) {
    int id = v.getId();

    Fragment fragment = null;
    Bundle args = new Bundle();
    switch ( id ) {
    case R.id.fragment1:
        fragment = new FragMent1();
        args.putString("someKey1", "someValue1");
        fragment.setArguments(args);
        showFragment(fragment);
        break;
    case R.id.fragment2:
        fragment = new FragMent2();
        args.putString("someKey2", "someValue2");
        fragment.setArguments(args);
        showFragment(fragment);
        break;
    default:
        break;
    }
}

public void showFragment(Fragment fragment) {
    FragmentTransaction ft = getFragmentManager().beginTransaction();
    ft.replace(R.id.content, fragment);
    ft.commit();
}
