Question

I am attempting to split an image into pieces, lets say for example 16 chunks (4×4).Once i split the image how can i display these chunk image as a whole.

Should I use a bitmap or a drawable? Is there a method to split or will I have to make a custom method?

Answer 1

Use bitmap because it holds pixel of the image which will be good for you for future use, if you are willing to display that image.

for example —->

 Bitmap bm = BitmapFactory.decodeResource(getResources(), R.drawable.icon);
   ImageView iv = (ImageView) findViewById(R.id.imageView1);
   iv.setImageBitmap(bm);

–———————————–EDITED PART——————————————–

if you want to send image from place to another(one device to another), you to convert it into byte array like this —>

Bitmap bm = BitmapFactory.decodeResource(getResources(), R.drawable.icon);
 ByteArrayOutputStream baos = new ByteArrayOutputStream();
 bm.compress(Bitmap.Compress.JPEG, 100, baos);
 byte[] b = baos.toByteArray();

and then send this to the other device.
