android - 如何在 Android 中从文件路径重命名文件？

Question

我有一个存储在一个变量中的路径

字符串路径:

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

现在我只想重命名 1396854069062.jpg 的文件，我不知道该怎么做。

我的代码是:

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

任何帮助将不胜感激。

谢谢

Answer 1

试试这个方法，

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

不要忘记在 android list 文件中添加以下权限

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

编辑

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