将当前活动传递给超级[关闭]

Question

我如何将ActivityProfile传递给Set类（Superclass）？

注意：集合类中的activity字段是ActivityProfile

public class Set extends AppCompatActivity {
  protected View v_change_profile = null;
  protected TextView txtTitle;

  private Activity activity ;

  public Set(Activity activity) {
    this.activity= activity; 
    LayoutInflater inflater = activity.getLayoutInflater();
    v_change_profile = inflater.inflate(R.layout.edit_profile_dialog, null);

    txtTitle = v_change_profile.findViewById(R.id.txtTitle);
  }

//**************************************************

public class ActivityProfile extends Set {
    //...
}

您可以通过super.修饰符访问变量或调用超类的函数

比如：在Set类中，声明一个像private ActivityProfile profile这样的变量。

在ActivityProfile课程中，super.profile = this如果你想分配它
