All Implemented Interfaces:
```
public class ViewUtils

                    
```
Contains tools for usage in View animations and transformations. Also contains methods to handle major ui bug-fixes.

Nested Class Summary

Nested Classes
Modifier and Type	Class	Description
`public class`	`ViewUtils.DefaultAnimationListener`	Implementation of Animator.AnimatorListener that does nothing. Used as base class for creating anonymous classes, which doesn't force you to override all the methods. Also, ensures that DefaultAnimationListener.onAnimationFinished will be invoked not more than once per animation (which, for instance, can be possible on HTC One X).
`public final class`	`ViewUtils.HardwareLayerAnimationListener`	Applies View.LAYER_TYPE_HARDWARE to provided View on animation start and returns in to previous layer on animation finish.

Modifier and Type	Method	Description
`final Unit`	`saveViewTransformation(View view)`	Saves View transformation parameters (translation, imageScale, rotation, alpha), so they can later be restored with .
`final Unit`	`restoreViewTransformation(View view)`	Restores transformation values.
`final Unit`	`postOnPreDraw(View view, Runnable runnable)`	Executes Runnable right before global draw event, which is convenient if you want to be sure that provided View correctly calculated it's size.
`final Rect`	`getViewBounds(View view)`
`final Float`	`fitBitmapToView(Bitmap bitmap, View view, Float rotation)`	Convenient alternative for .
`final Float`	`fitDrawableToView(Drawable drawable, View view, Float rotation)`	Convenient alternative for .

  - saveViewTransformation
```
 final Unit saveViewTransformation(View view)
```
    Saves View transformation parameters (translation, imageScale, rotation, alpha), so they can later be restored with .restoreViewTransformation. Note, that this implementation uses View.setTag method to save parameters, so any existing tags will be overwritten.
  - restoreViewTransformation
```
 final Unit restoreViewTransformation(View view)
```
    Restores transformation values.
  - postOnPreDraw
```
 final Unit postOnPreDraw(View view, Runnable runnable)
```
    Executes Runnable right before global draw event, which is convenient if you want to be sure that provided View correctly calculated it's size.
  - getViewBounds
```
 final Rect getViewBounds(View view)
```
  - fitBitmapToView
```
 final Float fitBitmapToView(Bitmap bitmap, View view, Float rotation)
```
    Convenient alternative for .fitRectToView which creates rectangle from Bitmap
  - fitDrawableToView
```
 final Float fitDrawableToView(Drawable drawable, View view, Float rotation)
```
    Convenient alternative for .fitRectToView which creates rectangle from intrinsic size of Drawable
  - fitRectToView
```
 final static Float fitRectToView(View view, Float rotation, RectF imageBounds)
```
    Parameters:
    
    view - View in which rectangle should fit
    
    rotation - rotation of RectF in degrees relatively to its center
    
    imageBounds - RectF to fit
  - getALPHA_DEFAULT
```
 final Float getALPHA_DEFAULT()
```
  - getALPHA_TRANSPARENT
```
 final Float getALPHA_TRANSPARENT()
```
  - getSCALE_DEFAULT
```
 final Float getSCALE_DEFAULT()
```
  - getTRANSLATION_DEFAULT
```
 final Float getTRANSLATION_DEFAULT()
```
  - getDISABLED_ACTIONMODE_CALLBACK
```
 final ActionMode.Callback getDISABLED_ACTIONMODE_CALLBACK()
```
    Use this ActionMode.Callback if action mode should be disabled
  - setDISABLED_ACTIONMODE_CALLBACK
```
 final Unit setDISABLED_ACTIONMODE_CALLBACK(ActionMode.Callback DISABLED_ACTIONMODE_CALLBACK)
```
    Use this ActionMode.Callback if action mode should be disabled
