  • 0

I use TabHost and i have 2 tabs with 2 activityes i want to set second tab to be default tab but when tabhost start he load first tab1 and before tab2 an this is wrong because in these 2 activityes i load data from webservice !
My question is how to set current tab second tab without load first tab!

My tabhost code:

public class TabsHandler extends TabActivity    {
private static TabHost tabHost;
Intent intent;
    private void setupTabHost() {
    tabHost = (TabHost) findViewById(android.R.id.tabhost);
    tabHost.setup(this.getLocalActivityManager());
    tabHost.setCurrentTab(1);
    }
    @Override
    protected void onCreate(Bundle savedInstanceState) {
            super.onCreate(savedInstanceState);
            if(!isOnline())
                Utils.DialogNoInternet(this);
            String authToken = getIntent().getExtras().getString("token");
            Long role = getIntent().getExtras().getLong("role");
            String EventIdNotification =getIntent().getExtras().getString("EventIdNotification");
            setContentView(R.layout.event_list_tabs);    

            setupTabHost();
            Resources res = getResources();
            tabHost.getTabWidget().setClipChildren(false);


            setupTab(new TextView(this), res.getString(R.string.tab1_List),new Intent().setClass(this, EventListActivity.class).putExtra("authToken", authToken).putExtra("role", role).putExtra("EventIdNotification", EventIdNotification));
            setupTab(new TextView(this), res.getString(R.string.tab2_List),new Intent().setClass(this, PastEventListActivity.class).putExtra("authToken", authToken).putExtra("role", role).putExtra("isPast", "true"));
            tabHost.setCurrentTab(1);



    }
    public void switchTab(int tab){
            tabHost.setCurrentTab(tab);
    }
    public boolean isOnline() {
        ConnectivityManager cm =
            (ConnectivityManager) getSystemService(Context.CONNECTIVITY_SERVICE);
        NetworkInfo netInfo = cm.getActiveNetworkInfo();
        if (netInfo != null && netInfo.isConnectedOrConnecting()) {
            return true;
        }
        return false;
    }
    private void setupTab(final View view, final String tag,Intent intent) {
            View tabview = createTabView(tabHost.getContext(), tag);
            TabSpec setContent = tabHost.newTabSpec(tag);
            setContent.setIndicator(tabview);
            setContent.setContent(intent);
            tabHost.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);
            tv.setText(text);
            return view;
    }
