该函数可以用于各种编程语言中,包括但不限于JavaScript、Python、Java等。 该函数的基本思路是遍历数组中的每个元素,然后根据特定的条件对元素进行检查和更改。以下是一个示例的JavaScript实现: 代码语言:txt 复制 function isCheck(arr) { for (let i = 0; i < arr.length; i++) { if (arr[i] === ...

In Python we frequently need to check if a value is in an array (list) or not. Pythonx in listcan be used for checking if a value is in a list. Note that the value type must also match. Here is a quick example: a = ["1", "2", "3"] ...

今天在自己项目里添加了第三方module依赖,添加后还用之前的签名文件打包apk时出现“AAPT2 error: check logs for details”的错误,如下图: 接下来我们看看如何解决这样的问题。 首先,AAPT2 是打包资源文件的工具,如果 AAPT2 报错了,那么可以肯定是资源文件有问题(且不论AAPT2内部错误)。 构建 App 的时候,打开 ...
