For a week I have been searching and trying but I cannot find a proper solution for the following Android issue. (This is how I see it now and it may be the wrong approach)

We have a MainActivity and 3 Fragments: SingleAnswer, MultipleAnswer and ImageAnswer. The MainActivity retrieves an object with a random amount of questionTypes. The MainActivity uses starts a fragment based on the retrieved object.

How can I iterate through Fragments?

For example: First there is a MultipleAnswer Fragment and a answer is selected by the user. Then the next Fragment has to be loaded...

I don't know if this approach is right or if I have to look for something else than Fragments.

  • You can `replace` the fragment depending on the object what you received. You can also use `getFragmentById()` or `getFragmentByTag()` to retrieve the fragment if it is already there. – Gaurav Gupta Sep 23 '13 at 14:10

Someone also faced this problem. At the first glance there does not seem to be a getFragments method. However you can use a workaround as specified here:

Is there a way to get references for all currently active fragments in an Activity?

it is not real to iterate fragments that was not added, only replace will be good choice or
try to use ViewPager for it with adapter example: http://geekyouup.blogspot.com/2011/07/viewpager-example-from-paug.html in the main activity initialize your adapter like this one :

 mContainer = (ViewPager) mainLayout.findViewById(R.id.pager_container);
    myPager = mContainer.getViewPager();
    adapter = new MyPager(myPager,new String[]{"R.layout.first","R.layout.second","...."});

myPager.setAdapter(adapter);
myPager.setCurrentItem(0);
