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>
