Are you referring to the Up button in your app's action bar, or the system's Back button?

How is this related to FIFO or LIFO? The back buttons can be somehow confusing, as hardware and logical buttons have a different effect on the transition.
- Logical back would take you to the parent activity.
- Hardware back would take you to the currently previous activity.
So, it would be worth handling both of them in your code. Then loading the activity, with the previous state or from ground up. Read the following two guides to learn more about "proper navigation":

I want to draw horizontal dashed lines programmatically between programmatically generated TextViews. I found this code on Internet:
Paint fgPaintSel = new Paint();
fgPaintSel.setARGB(255, 0, 0, 0);
fgPaintSel.setStyle(Paint.Style.STROKE);
fgPaintSel.setPathEffect(new DashPathEffect(new float[]{5, 10}, 0));
I just copied and pasted this code but nothing happened. What should I do to draw a dashed line? Thanks.

You need to add the code to do the actual drawing of the line. It would be better to study the documentation[^] rather than copying code from random places on the internet.

How to access the file system (SD Card files) of Master device to client devices for file accessing via bluetooth like Bluetooth file transfer application in play store?
please help
|
|

It had been a negative response until now, and it will be a no unless you start something yourself!
Start here and read the documentation, then learn how to use the protocols to work with Bluetooth connections and devices, http://developer.android.com/guide/topics/connectivity/bluetooth.html[^]

Is that supposed to be helpful in diagnosing the problem?

Does class-1 own the fragment? In class-1's onCreate() method, do you have something like:
Bundle arguments = new Bundle();
Values v = (Values) getIntent().getSerializableExtra(MyFragment.ARG_ITEM_ID);
arguments.putSerializable(MyFragment.ARG_ITEM_ID, v);
MyFragment fragment = new MyFragment();
fragment.setArguments(arguments);
getFragmentManager().beginTransaction().add(R.id.thread_detail_container, fragment).commit(); You can more easily see how to do this very thing by looking at the Master/Detail sample project.
