how to get directory of images to access via code

Issue

I want to add images with my app. I see option to add images in res/drawable folder. But I have lot of images. How can I access the directory? e.g. to access sdcard location I can use

File directory = new File(
        android.os.Environment.getExternalStorageDirectory()
                + File.separator + AppConstant.PHOTO_ALBUM);

But I have images in drawable folder which will be with app. So how to access directory in android project. So that I can use something like File[] listFiles = directory.listFiles(); Is there better way to save and access images through app?

Solution

The solution I can suggest you is to store your images into "Asset" folder in your project and you can easily access all the images at once by following these steps:

1. Create a folder named "images" in your asset folder.
2. Copy all your images in that "images" folder.

3.Get your images list like this:

String[] images =getAssets().list("images");
ArrayList<String> listImages = new ArrayList<String>(Arrays.asList(images));

4.Now set the images to your "imageview" like this:

InputStream inputstream=mContext.getAssets().open("images/"
                                  +listImages.get(position));
Drawable drawable = Drawable.createFromStream(inputstream, null);
imageView.setImageDrawable(drawable);
