Question

欢迎添加从SOAP检索到的ListView数据时遇到问题。当您创建ListView时会弹出以下错误：

04-06 00:12:47.852: W / dalvikvm (4092): threadid = 1: thread exiting with uncaught exception (group = 0x409c01f8) 
04-06 00:12:48.123: E /AndroidRuntime (4092): FATAL EXCEPTION: main 
04-06 00:12:48.123: E /AndroidRuntime (4092): android.content.res.Resources $NotFoundException: Resource ID # 0x7f08000c type # 0x12 is not valid

不明白发生了什么。

请帮助解决问题，并解释调用错误时发生的事情。

Answer 1

您应该按以下方式使用ArrayAdapter

new ArrayAdapter<String>(myContext, android.R.layout.simple_list_item_1, list)

而不是

new ArrayAdapter<String>(myContext, R.id.listaPytan, list)
