Question

Lets imagine the following structure:

ActivityA ---->  contains TabHostA, Button1

TabHostA  ---->  in one of its tabs holds the ActivityB that contains TextView1

The TabHost is filled with an intent:

TabSpec tab = mTabHost.newTabSpec("tab1").setIndicator("tab1")
        .setContent(new Intent(this, ActivityB.class));
mTabHost.addTab(tab);

And I want when the Button1 is pressed the TextView1 is changed. How can I access to TextView1 from ActivityA or communicate ActivityB and ActivityA for doing this change?

Please do no try to change the “tab-model” because it comes from a more complex problem (if interested search MapViews inside fragments) and thats the unique way it work

Answer 1

Maybe like that?

((TabActivity) getParent()).getTabHost()

Then you can edit the TextView of the given tab.
