Pass Data From Activity To Fragment Class Cast Exception

There are so many ways but i am using this one: Activity:(Main2Activity) public class Main2Activity extends AppCompatActivity{ private String myString = 'hello'; @Override protec

Solution 1:

You create your Fragment in MainActivity and it belongs to it, so you get MainActivity instead of Main2Activity when you use getAcitvity().

Solution 2:

Try making your getMyData() static

publicstaticStringgetMyData() {
return myString;

}

and then access it in fragment like

Main2Activity.getMyData();

Solution 3:

In your Activity, do the following

MyFragment fragmentObj=newMyFragment();
Bundleargs=newBundle();
args.putString("Data_Key", string_value);
fragmentObj.setArguments(args);

Now add this Fragment to stack using FragmentTransaction.

After this, in your Fragment class's onCreateView do the following

@Overridepublic View onCreateView(LayoutInflater inflater, ViewGroup container,
                             Bundle savedInstanceState) {

ViewrootView= inflater.inflate(R.layout.fragment_xml_view, container, false);
  if (getArguments() != null) 
  {
      StringvalueReceived= getArguments().getString("Data_Key");
  }
 return rootView;
}

Solution 4:

Create an object of MainActivity2 and access the method as follow:

MainActivity2 mn2=newManiActivity2();
mn2.getMyData();

Solution 5:

If you want to done this work you must have to keep your myFragment into Main2Activity instead of MainActivity.
