如何在Android中从文件路径重命名文件? [英] How to rename File From filepath in Android?

问题描述

我的路径存储在一个变量中

I have Path Which is stored into one variable That is

String filepath ="/mnt/sdcard/DCIM/Camera/1396854069062.jpg";

String filepath="/mnt/sdcard/DCIM/Camera/1396854069062.jpg";

现在，我只想重命名为 1396854069062.jpg 的文件.

我的代码是:

Now i want to rename only file that is 1396854069062.jpg I Reilly don't have any idea for how to do that.

File sdcard = Environment.getExternalStorageDirectory();
File from = new File(sdcard, filePath);
File to = new File(sdcard, "RChat_Rename.jpg";
from.renameTo(to);

任何帮助都会被感激.

谢谢

推荐答案

尝试这种方式，

File sdcard = Environment.getExternalStorageDirectory();
File from = new File(sdcard,"/1396854069062.jpg");
File to = new File(sdcard,"test.jpg");
from.renameTo(to);

别忘了在Android清单文件中添加以下权限

Do not forget to add below permission in android manifest file

<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />

修改

String filepath= Environment.getExternalStorageDirectory() + "/DCIM/Camera/";
File from = new File(filepath,"1396854069062.jpg");
File to = new File(filepath,"test.jpg");
from.renameTo(to);
