Using context in a fragment

Question

How can I get the context in a fragment?

I need to use my database whose constructor takes in the context, but getApplicationContext() and FragmentClass.this don't work so what can I do?

Database constructor

public Database(Context ctx)
{
    this.context = ctx;
    DBHelper = new DatabaseHelper(context);
}

Answer 1

You can call getActivity() or,

public void onAttach(Context context) {
    super.onAttach(context);
    this.activity = (CashActivity) context;
    this.money = this.activity.money;
}

Answer 2

On you fragment

((Name_of_your_Activity) getActivity()).helper

On Activity

DbHelper helper = new DbHelper(this);

Answer 3

Also you can use:

inflater.getContext();

but I would prefer to use

getActivity()

or

getContext

Answer 4

You could also get the context from the inflater parameter, when overriding onCreateView.

public static class MyFragment extends Fragment {
    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container,
                                 Bundle savedInstanceState) {
        /* ... */
        Context context = inflater.getContext();
        /* ... */
    }
}

Answer 5

@Override
public void onAttach(Activity activity) {
    // TODO Auto-generated method stub
    super.onAttach(activity);
    context=activity;
}

Answer 6

getContext() came in API 23. Replace it with getActivity() everywhere in the code.

See if it fixes the error. Try to use methods which are in between the target and minimun API level, else this error will come in place.
