1 | Fragment-Back-Stack
2 | ===================
3 |
4 | Fragment Back Stack manager while displaying fragments on single activity and need to maintain on back press
5 |
6 | Purpose
7 | -------------
8 |
9 | We know that there is activity stack in Android. We don't need to maintain the stack while opening or closing
10 | activity. It will automatically handle the stack and show you the top of activity when you pressed `back` button.
11 |
12 | But in fragment, its neccessary to handle them. Because Android is not going to handle them. We need to create
13 | a stack of fragment and manage them while pressing `back` button.
14 |
15 | So, I have created one demo to represent how to handle the fragment in Back Stack.
16 |
17 | Usage
18 | -------------
19 |
20 | In the sample application, you will find one object named `fragmentStack`. Its a `Stack` which will
21 | push and pop the fragment as per requirement.
22 |
23 | Whenever you are displaying any new fragment, just push that fragment into stack using following code.
24 |
25 | //here this fragment is our first fragment
26 | homeListFragment = new HomeListFragment();
27 | fragmentStack.push(homeListFragment);
28 |
29 | 
30 |
31 | And when you are displaying any other fragment over this fragment, use following code.
32 |
33 | We will create a new object of second fragment and add it to stack.
34 |
35 | //here this fragment is second fragment
36 | resultListFragment = new ResultListFragment();
37 | //hide the last fragment
38 | ft.hide(fragmentStack.lastElement());
39 | //push the new fragment into stack
40 | fragmentStack.push(resultListFragment);
41 |
42 | 
43 |
44 | When `backPressed` event fires, we will check whether stack size is `2` or not. If it is, then we will pop last
45 | fragment and display the previous fragment by following code.
46 |
47 | if (fragmentStack.size() == 2) {
48 | FragmentTransaction ft = fragmentManager.beginTransaction();
49 | fragmentStack.lastElement().onPause();
50 | ft.remove(fragmentStack.pop());
51 | fragmentStack.lastElement().onResume();
52 | ft.show(fragmentStack.lastElement());
53 | ft.commit();
54 | } else {
55 | //if size is `1` it means first fragment is visible and we can exit from application
56 | super.onBackPressed();
57 | }
