Ability to change the title on Tabs from TabGroup. It can be done natively.
Some native code that points out that this is both possible and simple:
Explanation: We grab the object of the TabGroup widget then we point that we need the first child (first tab starting from the left). Next step using this part of code: findViewById(android.R.id.title)) we find the text label (that refers to the Tab). It give us the ability to operate on it like with normal Label. We can change the text using the setText method.
