Question

public void onClick(View v) {

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

我想获取适配器类中操作栏的标题。正如你所看到的，我有活动的背景。

将您的活动名称转换为您的上下文。 示例;

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