如何在Android中以编程方式将图像文件从库复制到另一个文件夹 [英] How to Copy Image File from Gallery to another folder programmatically in Android

问题描述

我想从图库中挑选图像并将其复制到SDCard的其他文件夹中.

I want to pick image from gallery and copy it in to other folder in SDCard.

从图库中选取图片的代码

Code to Pick Image from Gallery

Intent photoPickerIntent = new Intent(Intent.ACTION_PICK);
    photoPickerIntent.setType("image/*");
    startActivityForResult(photoPickerIntent, REQUEST_CODE_CHOOSE_PICTURE_FROM_GALLARY);

我从content://media/external/images/media/681这个URI onActivityResult中获得了

I get content://media/external/images/media/681 this URI onActivityResult.

我要复制图像，

表格path ="content://media/external/images/media/681

在Android中sdcard的path = "file:///mnt/sdcard/sharedresources/路径.

To path = "file:///mnt/sdcard/sharedresources/ this path of sdcard in Android.

该怎么做?

推荐答案

OutputStream out;
            String root = Environment.getExternalStorageDirectory().getAbsolutePath()+"/";
            File createDir = new File(root+"Folder Name"+File.separator);
            if(!createDir.exists()) {
                createDir.mkdir();
            }
            File file = new File(root + "Folder Name" + File.separator +"Name of File");
            file.createNewFile();
            out = new FileOutputStream(file);                       

        out.write(data);
        out.close();
