用于两个不同对话框的对话框片段

Question

因此，我实现了一个继承DialogFragment的自定义类。我想将此对话框用于两种类型的操作：删除和编辑。为此，我对其进行了自定义，以便为每个按钮设置标题，描述和按钮文本。我要做的是创建一个接口，并有两个演示者：DeletePresenter和实现该接口的EditPresenter。界面应具有单击操作和对话框文本的设置。对此我很陌生，我不知道该如何连接所有这些对象（dialogFragment，presenters和接口）？如果有人能给我一个例子，那就太好了。

MyDialogFragment

public class MyDialogFragment extends DialogFragment implements View.OnClickListener {

    private DialogPresenterContract dialogPresenterContract;

    private String title, description, buttonTxt;

@Override
public void onClick(View view) {
    switch (view.getId()) {
        case R.id.dialog_btn:
            dialogPresenterContract.onActionClick(editText.getText().toString().trim(), onDialogActionListener);
            break;          
    }
}

DialogPresenterContract

public interface DialogPresenterContract {

    void onActionClick(String reason, MyDialogFragment.OnDialogActionListener onDialogActionListener);

    String getDialogTitle();

    String getDialogDescription();

    String getDialogButtonTxt();

}

DeletePresenter

 public class DeletePresenter implements DialogPresenterContract {
   //implement all methods
 }

EditPresenter

  public class EditPresenter implements DialogPresenterContract {
      //implement all methods
 }

[如果您想让MVP尝试一下，但是如果您不符合逻辑，那么我建议您在视图中写她的名字（MyDialogFragment）。

public class MyDialogFragment extends DialogFragment implements View.OnClickListener, MyView {

    public static MyDialogFragment newInstance(int num) {
        MyDialogFragment f = new MyDialogFragment();
        Bundle args = new Bundle();
        args.putInt("type", type);
        f.setArguments(args);

        return f;
    }

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        presenter.setType(getArguments().getInt("type"));
        ...
    }

    private Presenter presenter;

    private String title, description, buttonTxt;

    @override
    void setStrings(String title, String description, String buttonTitle) {
      ......
    }

    @Override
    public void onClick(View view) {
        switch (view.getId()) {
            case R.id.dialog_btn:
          dialogPresenterContract.onActionClick(editText.getText().toString().trim());
            break;          
        }
    }
}

MyView界面

interface MyView {
    void setStrings(String title, String description, String buttonTitle); 
}

演示者

class Presenter {

    private MyView view;
    private int type;

    public Presenter(MyView view) {
       this.view = view;
    }

    void setType(int type) {
       this.type = type;
    }

    void onClick(String text) {
       if (type == delete_type) {
         .....
        } else {
         ......
        }
    }
}
