Using context in a fragment

2021-6-3 anglehua

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);

You can use getActivity(), which returns the activity associated with a fragment.
The activity is a context (since Activity extends Context).

To do as the answer above, you can override the onAttach method of fragment:

public static class DummySectionFragment extends Fragment{
    public void onAttach(Activity activity) {
        DBHelper = new DatabaseHelper(activity);
