Android中的回收站 [英] Recycle Bin in Android

问题描述

你好，我试图在android中实现回收站应用程序，我遇到了 FileObserver 类来观察所有文件，但是问题是 FileObserver 仅通知该文件在删除后被删除，这是我的代码段

Hello, I''m trying to implement Recycle Bin application in android, I came across FileObserver class to observe all the files, but the problem is FileObserver only notifies that file is deleted after file deletion, here is my code snippet

public void onEvent(int event, String path) {
    if (path == null) {
        return;
    }
    //a file was deleted from the monitored directory
    if ((FileObserver.DELETE & event)!=0) {
        //Here I want to copy File some where else then I am getting 
        //'File Not found exception' because file is already
        // deleted before reaching this point of code

    }
}
