onbackpressed

I am getting a strange problem, while using Fragments and popping back them out. I have one Fragment Activity: Step1: I am attaching one Fragment in the onCreate of that Activity in the Starting named Fragment A as: This is the onCreate of Fragment Activity @Override protected void onCreate(Bundle savedBundleState) { super.onCreate(savedBundleState); setContentView(R.layout.activity_base_new); Fragement_Home home = new Fragement_Home(); FragmentManager manager = getSupportFragmentManager(); manager.beginTransaction().add(R.id.frameContent, home).addToBackStack("home").commit(); } Step:2 After

I have a list view which contains list of products and on the click of the list item, list details gets open. The list item contains values like gross weight, net weight etc. On the top of the list item details page I have a cross button instead of back button which on click will open a dialog saying "Do you want to save the changes" and with the button yes or no. On pressing YES, I am able to save the changes in the list view but on pressing NO, am not able to undo the changes. Below is the code for showing the dialog: @Override public boolean onBackPressed() { final AlertDialog alert = new

All data from that ListView is provided by a CursorAdapter . Whenever I pressed back button and return to activity, then click on the activity to start my fragment , all previous data still there stacking on top of each other.

But, if user changes orientation on detail screen, & then presses back button then the reverse transition animation doesn't work. Looking at this video's frames between 2:49 to 2:57 it seems to be possible even after orientation change. Any idea on this? Edit: Please check this video for

Changing activities with an animation is possible using the code below: Bundle animation = ActivityOptions.makeCustomAnimation(App.getContext(), R.anim.enter_from_right, R.anim.exit_to_left).toBundle(); startActivity(intent, animation); For fragments you can do something similar on FragmentTransaction: // ... transaction.setCustomAnimations(R.anim.enter_from_right, R.anim.exit_to_left); // ... This works! But I'd like to have an animation when pressing back (pop from backstack). For fragments you simply add 2 anim resources (popEnter & popExit): transaction.setCustomAnimations(R.anim.enter
