Bundle Null In Fragment

When i try to pass bundle variables to my Fragment in android they return as null in the fragment itself, yes I know this question has been asked a lot but this is my first 5 weeks

Solution 1:

Your problem is you are trying to manage Fragments in two different ways - manually and with a ViewPager. These are contradictory - choose one and only one.

You are setting the arguments Bundles in a transaction and then having the Adapter return Fragments that have no arguments set. To fix your problem, you will have to refactor your ViewPager method to set the arguments:

@Overridepublic Fragment getItem(int position) {
    switch (position) {
        case0:
            Fragmentfrag=newHeroDescriptionFragment();
            frag.setArguments(createBundle());
            return frag;
        case1:
            Fragmentfrag=newHeroStoryFragment();
            frag.setArguments(createBundle());
            return frag;
        default:
            returnnull;
    }
}

where createBundle() a method for creating the bundle as in your original code.

Solution 2:

use a static method in your fragment class like this

publicstaticMyFragmentnewInstance(String data1,String data2){
 MyFragment fragment=newMyFragment();
Bundle budle=newBundle();
bundle.putString("key",data1);
....
fragment.setArguments(bundle);
return fragment;
}


//then create new Fragment like thisMyFragment f=MyFragment.newInstance("a","b");
return f;
