文件不Foud异常 当压缩文件时发生，因为输出 zip 文件打开失败 ENOTDIR

Question

我是安卓新手，我目前正在我的项目中开发多个文件zip。我有一个创建数组列表并将其用作源文件，但我在pinstacktrace中得到了filenotfoundexception，上面写着Testzip，这是我的输出文件打开失败的ENOTDIR。我不知道为什么会发生.我尝试在字符串数组中转换 Arraylist，但什么也没发生，但创建了垃圾值，我该如何解决这个问题。Zipfile（ArrayListzipinputlist）是我的zip函数

这是我的代码

Answer 1

您正在尝试访问：/storage/sdcard/formpicture.JPG/storage/sdcard/Test.zip在zipFile函数中的行File storagefileindex = new File(zipInputList.get(i), zippedfile);中。

只使用File storagefileindex = new File(zipInputList.get(i));
