Passing an Object from an Activity to a Fragment

Question

I have an Activity which uses a Fragment. I simply want to pass an object from this Activity to the Fragment.

How

Answer 1

You should create a method within your fragment that accepts the type of object you wish to pass into it. In this case i named it "setObject" (creative huh? :) ) That method can then perform whatever action you need with that object.

MyFragment fragment;

@Override
protected void onCreate(Bundle savedInstanceState)
{
    super.onCreate(savedInstanceState);

        if (getSupportFragmentManager().findFragmentById(android.R.id.content) == null) {
            fragment = new MyFragment();
            getSupportFragmentManager().beginTransaction().add(android.R.id.content, detailsFragment)
                    .commit();
        } else {
           fragment = (MyFragment) getSupportFragmentManager().findFragmentById(
                    android.R.id.content);
        }


        fragment.setObject(yourObject); //create a method like this in your class "MyFragment"
}

Note that i'm using the support library and calls to getSupportFragmentManager() might be just getFragmentManager() for you depending on what you're working with
