Answer 1

Try this code. adjustViewBounds attribute makes the ImageView the same size as image that you put in it.

<ImageView
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:adjustViewBounds="true" />

If you need specific width or height change the wrap_content value.
