Start Activity in TabActivity1 from TabActivity2

So in my application I'm using two different Tabhosts.Here is an example

TABHOST1 Contains :

TAB1 | TAB2 | TAB3 | TAB4 | TAB5

TABHOST2 Contanins :

TB1 | TB2 | TB3 | TB4 | TB5

TAB2 - Activity 1

TB2 - Activity 2

So basically I want to start Activity 2, using Activity 1.开发者_如何学GoThe both activities are in different TABHOSTS so I need to keep the TABHOST2 when I start Activity 2,from Activity 1 (which is in TABHOST1).

Any suggestions how can I do that? Thanks in advance!

Pass the selected tab index from Activity1 While starting Activity2 from Activity1

Intent in = new Intent(this, TABHOSTS2.class); //TABHOSTS2 or whatever your second TabActivity is. 
in.putExtra("SelectedTab", 1);
startActivity(in);

and in you TABHOSTS2 which will be TabActivity, do something like:

public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.tabs); 
    //set you Tabs and blah blah

    int selectedTab = getIntent().getIntExtra("SelectedTab", 0);
    tabHost.setCurrentTab(selectedTab);
}

to start activity2 all you need to do is startActivity , no need for tabhost 2 . if your problem is how to keep child activity ( activity 2 in your case ) inside tabhost , go through ActivityGroup doc ,which will guide you about nested activities inside tabHost
