我不知道是什么原因引起的.我可以在片段上使用相同的方法，但是在此适配器中它不起作用.
I don't know what's causing the problem. I can use the same method on my fragments but in this adapter it's not working.
推荐答案
更改
adapter = new AdapterPOI(getApplicationContext(), ....)
到
adapter = new AdapterPOI(this, ....)
调用适配器的构造函数的代码中的
.您收到错误消息是因为 getApplicationContext()无法转换为 ActivityCategorySelected .这是一个Application上下文；而adapter期望的是Activity的context.
in the code where you call the adapter's constructor. You get the error because getApplicationContext() cannot be casted to an ActivityCategorySelected. That's an Application context; whereas the adapter is expecting an Activity's context.
这篇关于无法在适配器内使用finish()的文章就介绍到这了，希望我们推荐的答案对大家有所帮助，也希望大家多多支持IT屋！
