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

<pre><code>Bitmap b = ((BitmapDrawable)imageView.getBackground()).getBitmap();
int w = b.getWidth();
int h = b.getHeight();
</code></pre>

or do like here

<pre><code>imageView.setDrawingCacheEnabled(true);
Bitmap b = imageView.getDrawingCache();
int w = b.getWidth();
int h = b.getHeight();
</code></pre>

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

for only ImageView size 

<pre><code>imageView.getWidth(); 
imageView.getHeight(); 
</code></pre>

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

<pre><code>Drawable d = getResources().getDrawable(R.drawable.yourimage);
int h = d.getIntrinsicHeight(); 
int w = d.getIntrinsicWidth(); 
</code></pre>

For some reason accepted answer didn't work for me, instead I achieved the image dimension as per the target screen dpi like this.

<h2>Method 1</h2>

<pre><code>Context context = this; //If you are using a view, you'd have to use getContext();
Resources resources = this.getResources();
BitmapFactory.Options bounds = new BitmapFactory.Options();
bounds.inJustDecodeBounds = true;
BitmapFactory.decodeResource(resources, R.drawable.cake, bounds); //use your resource file name here.
Log.d("MainActivity", "Image Width: " + bounds.outWidth);
</code></pre>

Here is the original link

<a href="http://upshots.org/android/android-get-dimensions-of-image-resource" rel="nofollow noreferrer">http://upshots.org/android/android-get-dimensions-of-image-resource</a>

<h2>Method 2</h2>

<pre><code>BitmapDrawable b = (BitmapDrawable)this.getResources().getDrawable(R.drawable.cake);
Log.d("MainActivity", "Image Width: " + b.getBitmap().getWidth());
</code></pre>

It doesn't show the exact number of pixels in the image resource but a meaningful number perhaps someone can explain further.

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