[android-developers] Re: How to resize an icon at run time to achieve specific size

Hi Guys,

I've found the solution and in case you guys are interested the
following code will do the work for icon resize.

Regards,
argongold
----------------------

public Drawable scaleIcon(Drawable mIcon){

int width = mIcon.getMinimumWidth();
int height = mIcon.getMinimumHeight();

int newWidth = 42;
int newHeight = 42;

// calculate the scale to apply
float scaleWidth = ((float) newWidth) / width;
float scaleHeight = ((float) newHeight) / height;

// createa matrix for the manipulation
Matrix matrix = new Matrix();

// resize the bit map
matrix.postScale(scaleWidth, scaleHeight);

// recreate the new Bitmap
Bitmap bmp = ((BitmapDrawable) mIcon).getBitmap();
Bitmap resizedBitmap = Bitmap.createBitmap(bmp, 0, 0, width,
height, matrix, true);

// make a Drawable from Bitmap to allow to set the BitMap
// to the ImageView, ImageButton or what ever
BitmapDrawable newIcon = new BitmapDrawable(resizedBitmap);

return newIcon;
}
