If by selecting a tab you can switch to a certain fragment e.g tab1 brings up Fragment A, then all you need to do is select that tab. For example your currently viewing Fragment B and need to check some condition which will determine whether you switch to Fragment A or C

ActionBar bar = getSupportActionBar();
if(condition){
    bar.setSelectedNavigationItem(1); //where 1 is the position of tab1
}else{
    bar.setSelectedNavigationItem(3); //for tab3
}
