Horizo​​ntalScrollView从/ drawable文件夹获取图像

Question

I am using HorizontalScrollView in order to create some Gallery-like option and right now I am getting the images from an folder in the external drive. But I figured that I don't need, also shouldn't do that since the images I wanted to show is predetermined images. So I will simply change the directory to the drawable folder but I am not sure which path to go. So right now I am getting the directory with this: String path1= Environment.getExternalStorageDirectory().getAbsolutePath();

I found two more methods for directory retrieval but I am not sure which one to use.

String path2 = Environment.getDataDirectory().getAbsolutePath();

String path3= Environment.getRootDirectory().getAbsolutePath();

First one returns "/mnt/sdcard" , second returns "/data" , third one "/system" .

Which one should I use in order to reach /drawable folder inside this way?

None of them. Those are all for files on the filesystem. Drawable resources are not files on the filesystem.

Use getResources().getDrawable() to retrieve a Drawable given its ID (eg, R.drawable.foo ).
