My application needs to update tab indicator dynamically, I'm trying to do this by invoke TabSpec.setIndicator(), but it doesn't work. Here is my code:
In onCreate method of TabActivity:
tabHost = getTabHost();
TabSpec tabSpec = tabHost.newTabSpec("abc");
tabSpec.setIndicator("helloabc");
tabSpec.setContent(new MyViewFactory());
tabHost.addTab(tabSpec);
Now I need to change tab indicator to another string, for example, "xyz"
TabSpec tabSpec = MyTabActivity.getTabSpec();
tabSpec.setIndicator("xyz");
But it doesn't work. So I'd like to know how to change tab indicator after it is added to the tabhost? Many thanks.
Solution
Thanks to @CommonsWare, I make it by using TabWidget.getChildAt, here is my code for your convenience:
TextView title = (TextView) tabHost.getTabWidget().getChildAt(tabId).findViewById(android.R.id.title)
title.setText("xyz");
I apologize for my earlier incorrect answer, now deleted.
Try using getChildViewAt()
on TabWidget
.
