I got the following problem with my android app:

I have a TabHost containing some Fragments as Tabs. These Fragments have been added programmatically. Now I would like to replace the content of a tab with an other Fragment. And I don't know how to achieve that. I found how to replace a fragment which was added via xml, but that is not what I'm trying to achieve.

Thanks in advance for any suggestions.

EDIT: the requested source (only the relevant parts, if more is needed please tell me)

I have a method to initialize the tabhost and add the tabs/fragments programmatically:

private void initialiseTabHost(Bundle args) {
    mTabHost = (TabHost)findViewById(android.R.id.tabhost);
    mTabHost.setup();

    addUserListTab(args);
    //methods to add other tabs


    mTabHost.setOnTabChangedListener(this);
}

private void addUserListTab(Bundle args){
    TabInfo tabInfo = null;
    LayoutParams tabIconParams = new LayoutParams(200, 110);
    tabIconParams.setMargins(0, 0, 0, 0);
    View userIndicator = LayoutInflater.from(this).inflate(R.layout.tab_indicator,mTabHost, false);
    ImageView userIcon = (ImageView) userIndicator.findViewById(R.id.tab_icon);  
    userIcon.setLayoutParams(tabIconParams);
    TabSpec specUser = mTabHost.newTabSpec("user");
    specUser.setIndicator(userIndicator);
    userIcon.setImageDrawable(getResources().getDrawable(R.drawable.selector_user));
    userIcon.setScaleType(ImageView.ScaleType.FIT_CENTER);

    AddTab(this, this.mTabHost, specUser, ( tabInfo = new TabInfo("user", ListUserFragment.class, args)));
    this.mapTabInfo.put(tabInfo.tag, tabInfo);

}
private static void AddTab(MainActivity activity, TabHost tabHost, TabHost.TabSpec tabSpec, TabInfo tabInfo) {
    // Attach a Tab view factory to the spec
    tabSpec.setContent(activity.new TabFactory(activity));
    tabHost.addTab(tabSpec);
}

The Problem is that I don't understand how I can replace the ListUserFragment which I added programmatically to the tabhost. When I pass the container of the tabhost how can I specify which tab of the currently four should contain the new fragment and of course the old should be removed/hidden.

You need to get the FragmentManager and begin a FragmentTransaction to replace the current Fragment with another one. 

 getFragmentManager().beginTransaction().replace(R.id.container, new Fragment()).commit();

Be sure to also read the official fragment guide..

    This does not seem to work for replacing fragments which are added programmatically. The R.id. container describes the container of the old fragment which I do not have since I added the fragment and it's parent a TabHost programmatically. – soriak Jan 24 '13 at 15:50
  • This works, for every kind of fragment. Post me the source of your project. – Leandros Jan 24 '13 at 15:53
  • I provided the relevant parts of my source in my EDIT. If any more is needed please tell me. I hope that this enough to illustrate my problem. Thanks in advance – soriak Jan 25 '13 at 09:05
