Craete a method like this and pass your tab data like its view,its name and Its fragment class..

/**
 * Used to create a tab
 * 
 * @param view
 * @param tag
 * @param name
 */
private void setupTab(final View view, final String tag, Class<?> name) {
        View tabview = createTabView(this, tag);
        TabSpec setContent = tabHost.newTabSpec(tag).setIndicator(tabview)
            .setContent(new TabContentFactory() {
                public View createTabContent(String tag) {
                    return view;
                }
            });
    tabHost.addTab(setContent, name, null);
}



/**
 * Used to create tabview object and setting parameters
 * 
 * @param context
 * @param text
 * @return
 */
private View createTabView(final Context context, final String text) {
    View view = LayoutInflater.from(context).inflate(R.layout.tab_layout,
            null);
    Button _button = (Button) view.findViewById(R.id.tabText);
    _button.setText(text);
    return view;
}

And call that method like this..

setupTab(new Button(this), "Tab1", Fragment1.class);
setupTab(new Button(this), "Tab2", Fragment2.class);

@kalyanpvs Are you using `android.support.v4.app.FragmentTabHost` ? – AlexAndro Sep 13 '14 at 11:55
@kalyanpvs I'm also having one main activity and three fragments with bottom tab buttons(I used one library for this). Here, I'm having listview for two fragments. One for search fragment and another one for favourite. If I add my fragments by add method. Then it calls each time when I click the tab button. So my listview state changes automatically and it begins with first list item. I need to save listitem. Help me please.. Thanks in advance – Vinoth Vino Oct 22 '16 at 14:08
