Morph transitions from buttons to dialogs and back

MorphTransitions

Morph transitions from FAB to dialog, and Button to dialog

Inspired by Plaid

Usage

See the sample app. Typical usage:

MorphTransform.addExtras(intent, color, dialogCornerRadius);
ActivityOptions options =
        ActivityOptions.makeSceneTransitionAnimation(MainActivity.this, button,
                getString(R.string.morph_transition));
startActivity(intent, options.toBundle());

in the first activity, then:

MorphTransform.setup(this, container, color, dialogCornerRadius));

in the next activity. Be sure that you override onBackPressed() and call ActivityCompat.finishAfterTransition(DialogActivity.this);

In addition, be sure that your activities themes have the attribute:

<item name="android:windowContentTransitions">true</item>

morphtransitions's Issues

change morph drawable shape

Hello. I have been trying this demo and i made a little adjustments, but i cant figure it out something.
I realised the morph Fab to Dialog shape is build depending of the dialog width/height ratio. for instance, if the dialog is a rectangle, the morphing fab will transform from a circle to a rectangle. but if the dialog is more like a square, the fab morphing will be from a circle to a circle. I want to achieve a 'rectangular' morph even with a square dialog shape. Can you give me a hint?

AnimUtils is package-private

Hi, the AnimUtils class has no access modifier (this is only available to this package), but in Plaid it's public and I need access to the TransitionListenerAdapter (that is what it is for, public usage).
