安卓如何显示文件全名
‘壹’ 安卓系统 隐藏文件 始文件不被扫描
在不想被扫描的文件夹里添加一个文件,全名为“.nomedia”,注意不要引号,而且n前面有个点哦!其实你只要下载个“快图浏览”软件就可以办到了!
手机:iPhone12
系统:iOS14
软件:网络网盘
1、点击放大镜,输入我们要查找的文件名字,可以是文件全名,也可以是文件名字的其中一部分。这里我们要查找的是一个名字中带有1234的文件,我们可以直接输入数字1234,输入后点击屏幕右下角,也就是输入法上面的搜索按钮。

‘叁’ android获取本地文件名字
我写了个例子,你看能用吗?

‘陆’ 安卓版手机如何打开后缀为exe或chm的文件
因为exe是微软运行库打包,是windows桌面版(x86架构)的专有的安装格式,其他的任何系统没有办法打开的,所以,不要考虑用安卓打开exe了。
chm格式是常见的帮助文档格式,去任何应用市场或者网页上搜chm阅读器的apk,然后安装即可。
广义来说安卓可以通过虚拟机的方式(5.0以后并没有听说过可行测试)安装windowsXP ,而且可以运行自带的exe小程序,但是没有办法再往上面安装程序了,毕竟底层开发环境完全不同。
