如何从扩展ActionBarActivity的另一个类向我的主要活动添加操作栏？

Question

My problem comes from the fact that Java cannot extend two different activities. I have my main activity extending FragmentActivity . I want to add ActionBar with the support to old Android versions. Hence, extending ActionBarActivity is needed. How can I use another class which extends ActionBarActivity to add the action bar in my main activity ?

Answer 1

Make your main activity extend ActionBarActivity

ActionBar activity itself extends FragmentActivity so you should be fine.
