Question

I want to get the height and width of an image bitmap that is either in ImageView or a background image. Please help me, any help will be appreciated.

Answer 1

You can get height and width of ImageView by using getWidth() and getHeight() through while this will not give you the exact width and height of the image, for getting the Image width height first you need to get the drawable as background then convert drawable to BitmapDrawable to get the image as Bitmap from that you can get the width and height like here

Bitmap b = ((BitmapDrawable)imageView.getBackground()).getBitmap();
int w = b.getWidth();
int h = b.getHeight();

or do like here

imageView.setDrawingCacheEnabled(true);
Bitmap b = imageView.getDrawingCache();
int w = b.getWidth();
int h = b.getHeight();

the above code will give you current imageview sized bitmap like screen shot of device

for only ImageView size

imageView.getWidth(); 
imageView.getHeight(); 

If you have drawable image and you want that size you can get like this way

Drawable d = getResources().getDrawable(R.drawable.yourimage);
int h = d.getIntrinsicHeight(); 
int w = d.getIntrinsicWidth();
