我刚刚在1天前开始使用android dev。在下面的代码中,我只想让For循环在每次迭代后休眠5秒。但是,它只运行并打印一次。 我不确定我做错了什么。 Log cat:07-31 17:49:58.656:I / System.out(511):
07-31 17:49:58.665:I / System.out(511):START
07-31 17:49:58.676:I / System.out(511):NAMECHECK:NOTAVALIBLE
07-31 17:49:58.676:I / System.out(511):建议:
07-31 17:49:58.676:I / System.out(511):END
