title: Switching between activities within a tab bar layout
body: <p>I have this basic tab bar layout that creates a tab for three activities. What if I wanted to swap the activities within of the main activities? </p>
  
  <p>I want it to work like the Contacts app where you have your main contacts tab and a detailed activity when you click on a contact.</p>
  
  <pre><code>public void onCreate(Bundle savedInstanceState) {
              super.onCreate(savedInstanceState);
              setContentView(R.layout.main);
  
              TabHost tabHost = getTabHost();
  
              // Tab for Photos
          TabSpec photospec = tabHost.newTabSpec("Photos");
          // setting Title and Icon for the Tab
          photospec.setIndicator("Photos", getResources().getDrawable(R.drawable.icon_photos_tab));
          Intent photosIntent = new Intent(this, PhotosActivity.class);
          photospec.setContent(photosIntent);
  
          // Tab for Songs
          TabSpec songspec = tabHost.newTabSpec("Songs");
          songspec.setIndicator("Songs", getResources().getDrawable(R.drawable.icon_songs_tab));
          Intent songsIntent = new Intent(this, SongsActivity.class);
          songspec.setContent(songsIntent);
  
          // Tab for Videos
          TabSpec videospec = tabHost.newTabSpec("Videos");
          videospec.setIndicator("Videos", getResources().getDrawable(R.drawable.icon_videos_tab));
          Intent videosIntent = new Intent(this, VideosActivity.class);
          videospec.setContent(videosIntent);
  
          // Adding all TabSpec to TabHost
          tabHost.addTab(photospec); // Adding photos tab
          tabHost.addTab(songspec); // Adding songs tab
          tabHost.addTab(videospec); // Adding videos tab
  
      }*
