How to add bitmap array to an ArrayList?

Question

I have a Bitmap array in android, now I need to add this array to an ArrayList. I did this like

ArrayList<Bitmap> bmp_images = new ArrayList<Bitmap>(Arrays.asList(bmp));

But it showing an error The constructor ArrayList(List) is undefined

where bmp is the Bitmap array. What should i do please someone help me to fix this

Store the bitmap on your device and then add the path to the list. Why do you want bitmap in a list? — Raghunandan, Jun 03 '14 at 06:21
@GopalRao sorry its just a mistake about the bitmap array declaration — Hybrid Developer, Jun 03 '14 at 06:26
I figured. The error message is interesting, though. What was the mistake you were making? — drew moore, Jun 03 '14 at 06:28
@drewmore This error is shown if `bmp` is an array of something other than `Bitmap` — Apoorv, Jun 03 '14 at 06:38

@Apoorv that's what I thought was the case, but usually the exception thrown in that complains about being unable to do the conversion, not the constructor being undefined. — drew moore, Jun 03 '14 at 06:45

Hope this can help you.

ArrayList<Bitmap> bmp_images = new ArrayList<Bitmap>();
for(int i = 0; i < bmp.length ;i++ ){
     bmp_images.add(bmp[i]);

so whats wrong with `ArrayList bmp_images = new ArrayList(Arrays.asList(bmp));`??? – Gopal Gopi Jun 03 '14 at 06:21
-1 Is this really necessary? The code OP posted is good Java. Is there a concrete reason it can't work on Android? If so, that should be part of your answer. If not, I would *never* recommend using a loop where there is a library function available, and neither should you. – drew moore Jun 03 '14 at 06:21
@GopalRaonothing wrong with it thankyou – Hybrid Developer Jun 03 '14 at 06:27

You can add every single item one by one or you can consider using Collections.addAll.

You can simply use (assuming bmp is Bitmap[])

List<Bitmap> bmp_images = Arrays.asList(bmp);

And there is no need for creating a copy of this collection (depending on your needs)

But it seems you have some problems with declarations of bmp array, so inspect that part.
