我应该在DialogFragment本身（在回调方法之前）还是在Activity（在回调方法中）中解除DialogFragment？

Question

我有一个简单的DialogFragment包含一些数据和一个按钮。

public class SimpleDialogFragment extends DialogFragment {

    public static interface Callbacks {
        void onButtonClicked(SimpleDialogFragment dialogFragment);
    }

    static SimpleDialogFragment newInstance() {
        return new SimpleDialogFragment();
    }

    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
        View contentView = inflater.inflate(R.layout.fragment_dialog_simple, null);
        contentView.findViewById(R.id.some_button).setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                onSomeButtonClicked();
            }
        })
        return contentView;
    }

    private void onSomeButtonClicked() {
        Callbacks callbacks = (Callbacks) getActivity();
        // 
        // Should I dismiss here?
        // dismiss();
        // 
        callbacks.onSomeButtonClicked(this);
    }

}



public class SimpleActivity extends Activity implements SimpleDialogFragment.Callbacks {

    @Override
    public void onSomeButtonClicked(SimpleDialogFragment dialogFragment) {
        // 
        // Or should I dismiss here?
        // dialogFragment.dismiss();
        doSomething();
    }
}

Answer 1

onSomeButtonClicked()

之后，在callbacks.onSomeButtonClicked(this);中调用它会没问题

private void onSomeButtonClicked() { 
    Callbacks callbacks = (Callbacks) getActivity();

    callbacks.onSomeButtonClicked(this);
    dismiss();
}
