Rotatable

This is a helper class actually, it simplifies having a view as rotatable by setting touch events and handling a lot of boilerplate works! So if you need a component that needs to be able to rotate by touch, you do not have to deal with all these stuff.

Sample Video

Usage

You can apply this rotatable class to any view in your xml, just need to pass the required view into Rotatable builder and configure up to your needs.

Rotatable rotatable = new Rotatable.Builder(findViewById(R.id.targetView))

  .sides(R.id.frontView, R.id.backView)

.direction(Rotatable.ROTATE_X)

  .listener(rotationListener)

  .rotationCount(floatValue)

  .rotataionDistance(floatValue)

  .pivotX(intValue)

  .pivotY(intValue)

  .build();

Rotatable.Builder

sides(int frontViewResId, int backViewResId)
  • is optional, if you need your view to be rotated and display another view, you simply tell the library which one is front and which one is back -assuming that these two views are already in your rootView, otherwise it will crash- and library will swap them smoothly whenever it suppossed to.
rotationCount(float count)
  • Let's assume that you don't want user to swap over and over again your card so you can simply set how many times user can swap the view and library will calculate its maximum distance up to screen's width and height by user's touch and it will be limited to your selected count.
rotataionDistance(float distance)
  • You can also specify distance manually, but be aware of multi screen resolution and calculate carefully if you really need to do it. And important thing is that you cannot have both `rotationCount` and `rotationDistance` defined in your builder, because they have different calculations, so it will crash if you defined both.
pivotX(int pivotXValue) pivotY(int pivotYValue) // or  pivot(int pivotXValue, int pivotYValue)
  • You may need to change pivot position somehow to do it, you can use above methods or .pivot(intXValue, intYValue) to change both in once.

    But test it carefully! Because this can cause view not being drawn. How? & Why? Ok, Let's assume that you have a view with width matches screen's and you set pivotX as beginning, while rotating that will cause view's rotated width exceed screen's border and view will not be drawn until you get a point it can be fit to screen and drawn again.

Rotatable Object

We have built into Rotatable object, but why do we need that? Rotatable object has some useful methods that you may need to change some of configurations or notify rotatable on configuration changes. Such as:

rotatable.rotate(int direction, float degree, int duration, Animator.AnimatorListener listener)
  • Since you have this library implemented, and a rootView already defined into Rotatable object, why bother to create and ObjectAnimator and do your own animation? Simply call this method and library will do it. It has multiple rotate methods with different parameters, so you can call whichever works for you. You do not need to specify duration or listener.
rotatable.setTouchEnable(boolean enable) rotatable.isTouchEnable()
  • You can enable / disable touch events or check whether touch is enable on rotatable object or not at anytime.
rotatable.setDirection(int direction)
  • Possible to change rotation direction at runtime as well, but only with defined direction values in Rotatable class otherwise it will crash, so ensure that it is not possible to pass this method any other values except ROTATE_X - ROTATE_Y - ROTATE_BOTH
rotatable.orientationChanged(int newOrientation)
  • If your rotatable object needs to calculate its rotationCount or rotationDistance, then it might be tricky while user rotates screen and change orientation. So prevent this, you can listen orientationChanges and notify rotatable object about it, so it can rearrange itself. To do it so, you need to declare `configChanges` in your AndroidManifest.xml as `orientation` but as it is described [here][1] after Android v3.0 it is also required `screenSize` to capture this orientationChange events.
rotatable.drop()
  • This method is quite important, especially when you changed any pivot value of the rootView and you wanted to change some configurations of rotatable. So call drop method first, then you rebuild your rotatable object with same view but different configurations.
rotatable.takeAttention()
  • This is actually just for fun :) You can call this method where you want user to realize that he/she can move this component around :)

Are you tired of searching images for your Android app and copying each image file into its own drawable folder? I had the same problem and each icon I have copied I thought that I am wasting my time. Especially when Google published their big "Material Design Icon" pack. Nearly 70,000 icons in too many folders. So I thought that I need a tool which reads all icons of a folder and give me the chance to copy them easily into my project drawable folder. And here it is :-)
