Answer 1

Bitmap

And if you use something like this:

Bitmap resizedbitmap = Bitmap.createScaledBitmap(bmp1, image.getWidth(), image.getHeight(), true);

You can get the height and width with this:

or:

getIntrinsicWidth

getIntrinsicHeight

Answer 2

Images are adjusted for size based on the device the code runs on. When you open an image, Android checks the resolution and size of the device (you use BitmapDrawable(getResources(), bmp) so the resources take into account the device.

If your image was 100x100 and you run your code on a device that has a resolution of 2.0, your image will be 200x200.

You'll need to adjust your image size to the desired width and height on your own.

Answer 3

Bitmap image; image=BitmapFactory.decodeResource(getResources(),R.mipmap.wallpaper);

Bitmap originalsize= Bitmap.createScaledBitmap(image, image.getWidth(), image.getHeight(), true);
