How to display an Android gridview within a tabbed layout

Hi I'm setting up an android app and I'm using a tabbed interface. I'd like three tabs, a text based tab (About), a webkit tab (Store) and a gridview tab of images (Gallery) like in the Gridview tutorial.

I have the text and webkit tab working fine, but I cannot figure out the best way to format the gridview within the tab. Using the tabbed interface tutrial as an example, I am declaring the tab's content within the onCreate() event of the main class.

public class Woodroid extends TabActivity  {
    /** Called when the activity is first created. */
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);

        Resources res = getResources(); // Resource object to get Drawables
        TabHost tabHost = getTabHost();  // The activity TabHost
        tabHost.setCurrentTab(0);

        TabHost.TabSpec spec;  // Resusable TabSpec for each tab
        Intent intent;  // Reusable Intent for each tab

        // Create an Intent to launch an Activity for the tab (to be reused)
        intent = new Intent().setClass(this, AboutActivity.class);

        // Initialize a TabSpec for each tab and add it to the TabHost
        spec = tabHost.newTabSpec("about").setIndicator("",
                          res.getDrawable(R.drawable.ic_tab_about))
                      .setContent(intent);
        tabHost.addTab(spec);

        // Do the same for the other tabs
        intent = new Intent().setClass(this, StoreActivity.class);
        spec = tabHost.newTabSpec("store").setIndicator("Store",
                res.getDrawable(R.drawable.ic_tab_store))
            .setContent(intent);
        tabHost.addTab(spec);


        intent = new Intent().setClass(this, GalleryActivity.class);
        spec = tabHost.newTabSpec("gallery").setIndicator("Gallery",
                          res.getDrawable(R.drawable.ic_tab_gallery))
                      .setContent(intent);
        tabHost.addTab(spec);


      开发者_Python百科  tabHost.setCurrentTab(0);
    }
}

So then in the GalleryActivity.java I have the following

public class GalleryActivity extends Activity {
  public void onCreate(Bundle savedInstanceState) {
         super.onCreate(savedInstanceState);

            GridView gridview = new GridView(this);
            gridview.setAdapter(new ImageAdapter(this));

            setContentView(gridview);
     }
}

Which is an interpretation from the gridview tutorial. The thing that is missing then is the gridview layout definition. It seems I can force some of the attributes like gridview.setNumColumns(3); but that does not allow for the more flexible looking equivelant from the /layout/main.xml of the gridview version

android:layout_width="fill_parent" 
android:layout_height="fill_parent"
android:columnWidth="90dp"
android:numColumns="auto_fit"

Make sure to use a FrameLayout, c.f. tabbed example, set android:layout_width="WRAP_CONTENT" instead of fill_parent and then play with gravity and weight on each object element until it looks how you want it to.
