Question

I am trying to add rotation in imageview like this

        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:src="@drawable/poker_table"
        android:scaleType="fitXY"
        android:id="@+id/poker_table"
        android:rotation="45" //this line I added
        />

but the above code rotating my image from its center point. So please suggest any solution to rotate image from bottom right corner.

Answer 1

If you know the size of the View, you can use a pair of xml atttributes to set a pivot point for rotating or scaling a View: android:transformPivotX and android:transformPivotY

If we assume the View has a size of 100dp x 100dp:

android:transformPivotX="100dp"
android:transformPivotY="100dp"

Other possible units are sp, px, in, mm... but unfortunately match_parent will not work, and neither will 100%.

If you don't know the size of the View at compile time, your only option is to set the pivot point programmatically (using setPivotX() and setPivotY()) after determining its actual size.
