change bitmap size based device Android Studio [closed]

Question

In android studio the return value of this function BitmapFactory.decodeResource(getResources(), R.drawable.basictiles) changes based on device size.

as and example

Pixel:

• size = 1.792.000
• height, width = 1120,400

SM-G900F

• size = 2.580.480
• height, width = 1344,480

I'm trying to find a way to get the same image size for every device/resolution.

Answer 1

put your R.drawable.basictiles file inside drawable-nodpi folder

another approach is to use new BitmapFactory.Options() when decodeResource (third param) and set inScaled param to false

Answer 2

You may want to look at:

BitmapFactory.decodeResource(Resources res, int id, BitmapFactory.Options opts)

You can find it here

Essentially you need to pass in BitmapFactory.Options which can be used to control the resulting scaling, width, height etc of the Bitmap

BitmapFactory.Options options = new BitmapFactory.Options();
options.outHeight = ;// the height you want 
options.outWidth = ;// the width you want
BitmapFactory.decodeResource(getResources(), R.drawable.basictiles, options);
