Je suis très nouveau sur Android. Maintenant, je crée une petite application.
Je dois changer l'apparence de Android recherche par défaut dans 2.2. Donc, ici, j'essaie de changer l'arrière-plan des onglets. Pouvez-vous m'aider à le faire.
J'adore la façon d'utiliser le xml/style.
C'est ce dont j'ai besoin de cette sortie réelle.
Votre fichier XML Host Tab
TabHost
<?xml version="1.0" encoding="utf-8"?>
<TabHost xmlns:Android="http://schemas.Android.com/apk/res/Android"
Android:id="@Android:id/tabhost" Android:layout_width="fill_parent"

Android:layout_width="fill_parent" Android:layout_height="fill_parent">
<TabWidget Android:id="@Android:id/tabs"
Android:layout_width="fill_parent" Android:layout_height="wrap_content" />
<FrameLayout Android:id="@Android:id/tabcontent"
Android:layout_width="fill_parent" Android:layout_height="fill_parent">
</FrameLayout>
</LinearLayout>
</TabHost>
dans votre Activité principale
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
mTabHost = (TabHost) findViewById(Android.R.id.tabhost);
setupTab(new TextView(this), "Tab 1");
setupTab(new TextView(this), "Tab 2");
setupTab(new TextView(this), "Tab 3");
}
private void setupTab(final View view, final String tag) {
View tabview = createTabView(mTabHost.getContext(), tag);
TabSpec setContent = mTabHost.newTabSpec(tag).setIndicator(tabview).setContent(new TabContentFactory() {

return view;
}
});
mTabHost.addTab(setContent);
}
private static View createTabView(final Context context, final String text) {
View view = LayoutInflater.from(context).inflate(R.layout.tabs_bg, null);
TextView tv = (TextView) view.findViewById(R.id.tabsText);

Et enfin dans votre classe d'activité principale
mTabHost.getTabWidget().setDividerDrawable(R.drawable.tab_divider);
Et fini :)
