当我在适配器内设置finish方法时,我总是收到此错误。

我尝试删除所有项目insde OnRatingChanged,但错误仍然相同。

我不知道造成问题的原因。我可以在我的片段上使用相同的方法,但在此适配器中它不起作用。

答案 0 :(得分:3)

更改

adapter = new AdapterPOI(getApplicationContext(), ....)

adapter = new AdapterPOI(this, ....)

在您调用适配器构造函数的代码中。您收到错误是因为 getApplicationContext()无法转换为 ActivityCategorySelected 。这是一个Application背景;而adapter期待Activity&#39; context
