如何删除目录Java Android应用程序中的所有文件?当前代码正在删除该文件夹 [英] How to delete all files in a directory java android app? Current code is deleting the that folder

问题描述

这是我的代码

private final static String Dir = "/data/data/org.xbmc.kodi/cache/";
private void deleteDir(){
    try{
        /*File dir = Utils.getCacheDir(null, this, false, true);
        File path = new File(dir.getParentFile(), Dir);
        delete(path);*/
        String command = "rm -r "+Dir;
        Process process = Runtime.getRuntime().exec("su");
        DataOutputStream os = new DataOutputStream(process.getOutputStream());
        os.writeBytes(command + "\n");
        os.writeBytes("exit\n");
        os.flush();
        process.waitFor();
    }catch(Exception e){}
}

问题是，当我运行此命令时，它将删除该文件夹.但是我不想删除该文件夹.我要删除其中的所有文件.

The issue is when I run this it deletes the folder. But I don't want to delete the folder. I want to delete all the files inside it.

推荐答案

File dir = new File(Environment.getExternalStorageDirectory()+"Dir_name_here"); 
if (dir.isDirectory()) 
{
    String[] children = dir.list();
    for (int i = 0; i < children.length; i++)
    {
       new File(dir, children[i]).delete();
    }
}
