MorphButton

Inspired by https://github.com/dmytrodanylyk/android-morphing-button

Android Button that morphs to different shapes, derived from MaterialButton & AndroidX

Example

---

Dependency

Add this to your module's build.gradle file (make sure the version matches the last release):

Add it in your root build.gradle at the end of repositories:

allprojects {
	repositories {
		...
		maven { url "https://jitpack.io" }
	}
}

Add the dependency

dependencies {
    // ... other dependencies
    implementation 'com.github.ueen:MorphButton:1.1'
}

Usage

Declare your button in XML

<de.ueen.morphbutton.MorphButton
        android:id="@+id/morphButton"
        android:layout_width="wrap_content"
        android:layout_height="48dp"
        android:insetBottom="0dp"
        android:insetTop="0dp"
        android:insetRight="0dp"
        android:insetLeft="0dp"
        app:cornerRadius="24dp"
        app:backgroundColor="#3F51B5"
        android:text="Click Me"/>

Here its important, that you set all the insets to 0dp, its a bug in MaterialButton, that otherwise leads to strange behaviour

You can set everything as you need it (like: backgroundColor, icon, cornerRadius, textColor...)

Morph your button in code

here are a few examples what you can do

        one.setOnClickListener { it, morphId ->
            when(morphId) {
                MorphButton.FRIST -> {
                    it.morph(MorphButton.MorphParams("second",
                                                    circle = true,
                                                    icon = resources.getDrawable(R.drawable.ic_check_black_24dp, null),
                                                    iconSize = it.height/3*2,
                                                    color = getColor(android.R.color.holo_green_light)
                            ))
                }
                else -> {
                    it.reverse()
                }
            }
        }
        two.setOnClickListener { it, morphId ->
            when(morphId) {
                MorphButton.FRIST -> {
                    it.morph(MorphButton.MorphParams("second",
                            width = it.width*3,
                            radius = TypedValue.applyDimension(TypedValue.COMPLEX_UNIT_DIP, 8f, resources.displayMetrics).toInt(),
                            text = "clicked",
                            color = getColor(android.R.color.holo_blue_bright)
                    ))
                }
                "second" -> {
                    it.morph(MorphButton.MorphParams("third",
                            keepText = true,
                            color = getColor(android.R.color.holo_orange_light)
                    ))
                }
                else -> {
                    it.backToFirst()
                }
            }
        }

Notice, that you can morph the button from anywhere and also get the current id of the morph the button is in inside the onClickListener, so you can do things accordingly.
