Question

How can I determine the dimensions of my Scaled ImageView? I tried using getWidth() & getHeight it always returns 0. My xml layout for the ImageView is as follows:

<ImageView
            android:id="@+id/imgView"
            android:layout_width="300dp"
            android:layout_height="wrap_content"
            android:adjustViewBounds="true"
            android:scaleType="fitXY"
            android:src="@drawable/my_image" />

Please suggest something.

You are probably calling getWidth() method too early. The width and height of your ImageView will not be available until the View has been rendered on the screen. Try getting them within onWindowFocusChanged:

@Override
public void onWindowFocusChanged(boolean hasFocus) {
    super.onWindowFocusChanged(hasFocus);

    int width = iv.getWidth();
    int height = iv.getHeight();

    // ...
}
