Remember three important things:
1) A dog will have to pee 10 minutes after taking a drink. So pay attention to when she drinks and take her out ten minutes afterward.
2) A dog will have to crap 1/2 hour after eating. So pay attention to when she eats (ideally only once or twice per day) and take her out 1/2 hour afterward.
3) When training, dogs respond very well to praise (attention) and food (reward).
You have to help them create habits or they do not know better.
When taking her out to do her business, you have to let them know that that is why they are out there. As you approach the door to go outside, say "Let'* go outside. Go Potty" or similar simple command words that express the same thing and that you are comfortable with. Then, once you are outside, make it clear that she is outside for one purpose only, and that is to go "potty". Don't let her sniff or play unless the sniffing is a prelude to taking a dump.
Once she goes (either pee or poo) reward her with lots of praise and maybe even a dog treat. Then take her back inside or let her play for a while. If she makes a mistake during the training period and goes on your floor, immediately do the routine, as if she hadn't already gone. Take her outside and do the potty routine.
Remember that reward and attention are important in this process. Negative attention and punishment are still attention and she will respond to them if there is not positive attention.
The technique above really does work and a week or two of regular attention to this should be about all that is needed. After that, you will still need to pay attention to her drinking and eating times and to all the little signals she gives, indicating that she'* needing to go. Pacing and whining or scratching at the door are good indicators.
