android:launchmode="singleTask"
No resource identifier found for attribute 'launchmode' in package 'android' 当我在manifest.xml里配置了一个activity的启动模式为singleTask的时候,编译就会报错,如题目。 当我写了一个小demo,修改APIlevel,minSdkVersion 提高到21,问题解决。 但是我不想提高API level,请问有什么办法,能够保证我的activity是singleTask模式,或者 在不提高level的情况下,在manifest.xml里配置android:launchmode="singleTask"能够 编译通过而不是报如题的错误

下面这条语句一共创建了多少个对象:String s="a"+"b"+"c"+"d";
答:对于如下代码: String s1 = "a"; String s2 = s1 + "b"; String s3 = "a" + "b"; System.out.println(s2 == "ab"); System.out.println(s3 == "ab"); 第一条语句打印的结果为false,第二条语句打印的结果为true,这说明javac编译可以对字符串常量直接相加的表达式进行优化,不必要等到运行期去进行加法运算处理,而是在编译时去掉其中的加号,直接将其编译成一个这些常量相连的结果。 题目中的第一行代码被编译器在编译时优化后,相当于直接定义了一个”abcd”的字符串,所以,上面的代码应该只创建了一个String对象。写如下两行代码, String s ="a" + "b" + "c" + "d"; System.out.println(s== "abcd"); 最终打印的结果应该为true。 这是JAVA面试题及答案,但不十分理解,谁能帮我解释一下,System.out.println(s2 == "ab");为什么返回false?

互联网公司的裁员,能玩出多少种花样?
裁员,也是一门学问,可谓博大精深!以下,是互联网公司的裁员的多种方法:-正文开始-135岁+不予续签的理由:千禧一代网感更强。95后不予通过试用期的理由:已婚已育员工更有责任心。2通知接下来要过苦日子,让一部分不肯同甘共苦的员工自己走人,以“兄弟”和“非兄弟”来区别员工。3强制996。员工如果平衡不了工作和家庭,可在离婚或离职里二选一。4不布置任何工作,但下班前必须提交千字工作日报。5不给活干+...

活到老,学到老,程序员也该如此
全文共2763字,预计学习时长8分钟 图片来源:Pixabay 此前,“网传阿里巴巴要求尽快实现P8全员35周岁以内”的消息闹得沸沸扬扬。虽然很快被阿里辟谣,但苍蝇不叮无缝的蛋,无蜜不招彩蝶蜂。消息从何而来?真相究竟怎样?我们无从而知。我们只知道一个事实:不知从何时开始,程序猿也被划在了“吃青春饭”行业之列。 饱受“996ICU”摧残后,好不容易“头秃了变强了”,即将步入为“高...
Vue快速实现通用表单验证
本文开篇第一句话,想引用鲁迅先生《祝福》里的一句话,那便是:“我真傻,真的,我单单知道后端整天都是CRUD,我没想到前端整天都是Form表单”。这句话要从哪里说起呢?大概要从最近半个月的“全栈工程师”说起。项目上需要做一个城市配载的功能,顾名思义,就是通过框选和拖拽的方式在地图上完成配载。博主选择了前后端分离的方式,在这个过程中发现:首先,只要有依赖jQuery的组件,譬如Kendoui,即使使用...
