How to get height of Image in Imageview?

Question

I have set an image in imageview. It is showing in center of the screen as I have make its parent layout (Relative layout) to match parent. Imageview height and width is also set to match parent.

I want to get the height and width of Image in imageview.

I have used :

int imagWidth = imageView.getWidth();
int imagHeight = imageView.getHeight();

but by this we are getting height and width of Imageview .

Here is my xml:

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@+id/rl_root"
    android:layout_width="match_parent"
    android:layout_height="match_parent">

    <ImageView
        android:id="@+id/imag"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:adjustViewBounds="true"
        android:background="@android:color/black"
        android:src="@drawable/image2" />
</RelativeLayout>

Using ImageView.getDrawable().getInstrinsicWidth() and getIntrinsicHeight() will both return the original dimensions.
Getting the Drawable through ImageView.getDrawable() and casting it to a BitmapDrawable, then using BitmapDrawable.getBitmap().getWidth() and getHeight() also returns the original image and its dimensions.

try below code :

ImageView.getDrawable().getIntrinsicHeight()//original height of underlying image
ImageView.getDrawable().getIntrinsicWidth()//original width of underlying image
imageView.getMeasuredHeight();//height of imageView
imageView.getMeasuredWidth();//width of imageView

Try this :-

Bitmap b = ((BitmapDrawable)imageView.getDrawable()).getBitmap();
int w = b.getWidth(); 
int h = b.getHeight(); // height of your image

P.S :- h IS HEIGHT OF IMAGE ( Original Image Height )

Update

If you want to get the exact height of the image inside the imageView try this :-

int height = imageView.getDrawable().getIntrinsicHeight();
int height_in_dp = Math.round(height / (displayMetrics.xdpi / DisplayMetrics.DENSITY_DEFAULT));

height_in_dp is the height of the image in dp !!

@shantanu , what if image is not fit in imageView, . . for eg there's black space as shown in the pic posted by pragyaMendiratta , will this include that black space in height/width or not?? – Nirmal Prajapat Mar 10 '18 at 11:13
@NirmalPrajapat hii, it should not ...if its `fitXy` instead of `center crop` , it should work by taking the whole height and width !! – Santanu Sur Mar 10 '18 at 11:18
I'm not using scalType . . – Nirmal Prajapat Mar 10 '18 at 11:21
@shantanu: Even I tried your updated solution...its not giving accurate height of image – Pragya Mendiratta Mar 10 '18 at 11:23
which mobile are you using @PragyaMendiratta – Santanu Sur Mar 10 '18 at 11:24
without black spaces @NirmalPrajapat – Santanu Sur Mar 10 '18 at 11:26
@PragyaMendiratta if you are using large device try `displayMetrics.xxhdpi` instead of `displayMetrics.xdpi` – Santanu Sur Mar 10 '18 at 11:27
@shantanu : I have drawn a view of the same height - calculated according to your updated solution. plz check my updated post – Pragya Mendiratta Mar 10 '18 at 11:36
I am using moto g(2 gen) and I am not getting option of `displayMetrices.xxhdpi` @shantanu – Pragya Mendiratta Mar 10 '18 at 11:37
