[FIXED] Drag,Zoom or Rotate an ImageView

Issue

Here is a class which performs Drag, Zoom and Rotate of an ImageView.

xml

<?xml version="1.0" encoding="utf-8"?>
<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent" >

    <ImageView
        android:id="@+id/imageView"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:scaleType="matrix"
        android:src="@drawable/butterfly" />

</FrameLayout>

But it was all done on the Matrix of the ImageView using the imageView.setImageMatrix(matrix);

Not the actual image view.

Hence the below results:

Initial ImageView:

On Dragging right:

On Zooming in:

On Rotating:

Is there a way I can modify the ImageView to change as per it's Matrix?

Solution

You can call View.setRotation(), View.setPivotX(), View.setPivotY(), View.setScaleX(), View.setScaleY(), View.setTranslationX() and View.setTranslationY() ond any View including an ImageView.
