Afternoon all.
I am trying to display a PNG image in an ImageView on my mobile android application. The image comes in the form of a byte array from a database.
I'm new to android development, so I'm not sure as to the correct way to go about this. I have tried saving the file and setting the image using the URI but to no success.
File tempFile = File.createTempFile("NewsImage", lastNewsDTO.ImageExt, null);
FileOutputStream fos = new FileOutputStream(tempFile);
fos.write(lastNewsDTO.Image)
((ImageView)rootView.findViewById(R.id.ivNewsImage)).setImageURI(Uri.fromFile(tempFile));
Am I on the right lines or is there a better method?
Thanks for reading, help is appreciated!
If you are saying that you have a byte[]
that contains a PNG, use BitmapFactory
and its decodeByteArray()
method to convert that into a Bitmap
. Then, call setImageBitmap()
on the ImageView
with that Bitmap
.
Do not write things to disk that do not need to be written to disk.
Simple Use this :
byte[] data;
public static void setImageViewWithByteArray(ImageView view, byte[] data) {
Bitmap bitmap = BitmapFactory.decodeByteArray(data, 0, data.length);
view.setImageBitmap(bitmap);
}
