如何从创建它的活动中的DialogFragment调用finish()和其他非静态方法？我已经尝试从DialogFragment中的OnClickLisener传递消息,但无济于事.

我有一个非常简单的应用程序,包括MainActivity和DialogFragment:

    public class MainActivity extends Activity {
@Override
protected void onCreate(Bundle arg0) {
    super.onCreate(arg0);
    setContentView(R.layout.activity);
    showDialog();
}
public void showDialog() {
    DialogFragment newFragment = new ConfirmDialog();
    newFragment.show(getFragmentManager(), "dialog");
}

对话再次非常简单:

public class ConfirmDialog extends DialogFragment {
@Override
public AlertDialog onCreateDialog(Bundle savedInstanceState) {
    // Use the Builder class for convenient dialog construction
    AlertDialog.Builder builder = new AlertDialog.Builder(getActivity());
    builder.setMessage("Confirm you want to continue?")
           .setPositiveButton("Yes.", new DialogInterface.OnClickListener() {
               public void onClick(DialogInterface dialog, int id) {
                   //finish() MainActvity
                  }
               })
           .setNegativeButton("No.", new DialogInterface.OnClickListener() …
