在另一个布局中扩展布局

Question

我正在开发导航抽屉布局。另一个布局必须加载代替 drawer_layout onClick导航项。

NEW_DATABASE.NEW_SCHEMA

如何在mainlayout中加载另一个布局。？

Answer 1

你必须创建片段 （右键点击您的项目 - ＆gt;新建 - ＆gt;片段）。然后在此下方的Activity中加载..

 if (id == R.id.nav_camera) {

     CameraFragment camera = new CameraFragment();
     FragmentManager fragmentManager = getFragmentManager();
     FragmentTransaction fragmentTransaction = fragmentManager.beginTransaction();              
     fragmentTransaction.add(R.id.fragment_container, camera, "HELLO");
     fragmentTransaction.commit();


    } else if (id == R.id.nav_gallery) {

     GalleryFragment gallery = new GalleryFragment();
     FragmentManager fragmentManager = getFragmentManager();
     FragmentTransaction fragmentTransaction = fragmentManager.beginTransaction();              
     fragmentTransaction.add(R.id.fragment_container, gallery, "HELLO");
     fragmentTransaction.commit();

    }
