android - 如何在android中的非 Activity 类中获取ActionBar的标题

Question

public void onClick(View v) {
   //referenceOfActivity 
  // here is the context, don't know how to use it to get ActionBar title
  Toast.makeText(referenceOfActivity,"Already Liked",Toast.LENGTH_SHORT).show();
}

我想在适配器类中获取操作栏的标题。如您所见，我有 Activity 上下文。

Answer 1

将您的 Activity 名称转换到您的上下文中。示例；

((MainActivity) referenceOfActivity).getSupportActionBar().getTitle()
