以编程方式创建的Image文件夹未显示在Public文件夹中

我是Android开发的新手.我开发了一个程序，可以通过相机捕获图像并将其存储在mnt/sdcard/Pictures/MYFOLDER中.而且还有另一个按钮可以浏览图像.图像保存完美.但是，当我通过单击浏览"按钮浏览拍摄的图像时，它仅显示以下文件夹:图片，蓝牙，图像.当我导航到图片"文件夹时，MYFOLDER不存在.

I'm new to Android Development. I have developed a program that capture images via camera and stored in mnt/sdcard/Pictures/MYFOLDER. And also there is another button foe browse images. image save perfectly. But when I browse the taken images by clicking Browse button it only shows these folders: Pictures,Bluetooth,images. When I navigate to Pictures folder MYFOLDER does not exist.

这是我的浏览按钮

 Button buttonLoadImage = (Button) findViewById(R.id.btnBrowseimage);
        buttonLoadImage.setOnClickListener(new View.OnClickListener() {

            @Override
            public void onClick(View arg0) {

                Intent i = new Intent(
                        Intent.ACTION_PICK,
                        android.provider.MediaStore.Images.Media.EXTERNAL_CONTENT_URI);

                startActivityForResult(i, RESULT_LOAD_IMAGE);
            }
        });

请指导我.
