如何删除SD卡上的文件？ [英] How to delete a file from SD card?

问题描述

我创建一个文件作为附件发送到电子邮件。现在我要发送电子邮件后删除图像。有没有一种方法来删除文件？

我已经试过 myFile.delete（）; ，但它并没有删除文件

---

我用这个code为Android，所以编程语言是使用Java常用的Andr​​oid方式访问SD卡。我删除了 onActivityResult 的方法，该文件时的意图发送邮件后，返回到屏幕上。

解决方案

 档案文件=新的文件（selectedFilePath）;
布尔删除= file.delete（）;
 

在这里selectedFilePath是文件中要删除的路径 - 例如：

  

/sdcard/YourCustomDirectory/ExampleFile.mp3

I am creating a file to send as an attachment to an email. Now I want to delete the image after sending the email. Is there a way to delete the file?

I have tried myFile.delete(); but it didn't delete the file.

I'm using this code for Android, so the programming language is Java using the usual Android ways to access the SD card. I am deleting the file in the onActivityResult method, when an Intent is returned to the screen after sending an email.

解决方案

File file = new File(selectedFilePath);
boolean deleted = file.delete();

where selectedFilePath is the path of the file you want to delete - for example:

/sdcard/YourCustomDirectory/ExampleFile.mp3
