如何使用Navigation Drawer切换Activities[Android Studio]

Question

我在 Android Studio 1.4 中创建了导航抽屉 Activity。我的 Main Activity 已经设置好，现在我想通过 Navigation Drawer 切换到另一个 Activity。第二个 Activity (AddDataActivity) 应该收集一些 User Unputs 来创建应该显示在我的 Main Activities ListView 中的字符串。我的问题是，如果没有 "loosing" 我的导航抽屉，我不知道如何打开 AddDataActivity。

Intent AddData = new Intent(MainActivity.this, AddDataActivity.class);
MainActivity.this.startActivity(AddData);

我是否必须为每个 Activity 复制整个抽屉代码？还是使用 Fragments 会更好？

我现在用 Fragments 避免了这种情况。

@SuppressWarnings("StatementWithEmptyBody")
     @Override
     public boolean onNavigationItemSelected(MenuItem item) {
         Fragment fragment;
         FragmentTransaction ft = getSupportFragmentManager().beginTransaction();
         fragment = new ListViewFragment();
         int id = item.getItemId();

             if (id == R.id.nav_listview) {
                 fragment= new ListViewFragment();

             } else if (id == R.id.nav_add_data) {
                 fragment= new AddDataFragment();

             } else if (id == R.id.nav_settings) {
                 fragment= new SettingsFragment();

             } else if (id == R.id.nav_rooms) {
                 fragment= new SavedRoomsFragment();

             } else if (id == R.id.nav_legal_information) {
                 fragment = new LegalInformationFragment();
             }
         ft.replace(R.id.container, fragment);
         ft.addToBackStack(null);
         ft.commit();

         DrawerLayout drawer = (DrawerLayout) findViewById(R.id.drawer_layout);
         drawer.closeDrawer(GravityCompat.START);
         return true;
     }
