问题
I have created a MenuActivity which is having an Action Bar and an Split Action Bar. I want to use this actionbar and splitactionbar view for all activities in my application. I am a newbie to android so can somebody guide me stepwise about this.
Also I am trying to put the search icon on actionbar which is right now appearing on SplitActionBar. I have four icons on SplitActionBar and i want to show search icon on the actionbar not on the SplitActionBar. The search icon is a SearchView item which when clicked expands on ActionBar, which is very untidy. I want it to appear on rightmost position in the ActionBar and expand on the same when clicked.
This is MenuACtivity.java:

回答1:
Create BaseActivity which implements action bar.
And all your activities must inherit BaseActivity (not Activity)
public class BaseActiivity extends Activity{
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
// action bar implementation
}
}
public class MainActivity extends BaseAcivity{
//your code
}
