How do you detect what kind of file the resource is? In my case there could be videos and images.
So in case it's a video, I use a VideoView; and in the case of an image, I use an ImageView?
I'm getting the resource id like this:
AssetFileDescriptor afd = context.getResources().openRawResourceFd(resourceID); I think it's impossible without reading/ analyzing the binary data of files (like TrID). The easiest way is to prefix file names with predefined strings. For example:
video_file_00, video_file_01…image_file_00, image_file_01…Then you can use getResourceName(int) to parse the file names.
the only thing I have in mind is that you can check the file names using constants like this:
final String type = getApplicationContext().getResources().getResourceTypeName(resID); if(type.equals("drawable")){ // handle it like an image }else if(.....) //do some research for other constants
