Features

• Full Animation Control on Paths and VectorDrawables: Animate any attribute in a specific path in the VectorDrawable

fillColor, strokeColor, strokeAlpha, fillAlpha, size, width, height, scale, scaleX, scaleY, rotation, translationX, translationY, trimPathStart, trimPathEnd, trimPathOffset.

• Path morphing:

RichPathAnimator.animate(richPath)
       .pathData(pathData1, pathData2, ...)
       .start();

Just 3 Steps to Animate any path.

1. In your layout.

    <com.richpath.RichPathView
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        app:vector="@drawable/vector_drawable" />

2. Find your richPath.

// by path name
RichPath richPath = richPathView.findRichPathByName("path_name");
// or if it contains one path
RichPath richPath = richPathView.findFirstRichPath();
// or by index
RichPath richPath = richPathView.findRichPathByIndex(0);

3. Use the RichPathAnimator to animate your richPath.

RichPathAnimator.animate(richPath)
       .trimPathEnd(value1, value2, ...)
       .fillColor(value1, value2, ...)
       .start();

Example

notification icon vector drawable

<vector xmlns:android="http://schemas.android.com/apk/res/android"
    android:width="32dp"
    android:height="32dp"
    android:viewportHeight="32.0"
    android:viewportWidth="32.0">

    <group
        android:pivotX="16"
        android:pivotY="6.25">
        <path
            android:name="top"
            android:fillColor="#FFF7F7F7"
            android:pathData="M22,19.8v-5c0-3.1-1.6-5.6-4.5-6.3V7.8c0-0.8-0.7-1.5-1.5-1.5s-1.5,0.7-1.5,1.5v0.7c-2.9,0.7-4.5,3.2-4.5,6.3v5l-2,2v1h16v-1L22,19.8z" />

        <path
            android:name="bottom"
            android:fillColor="#FFF7F7F7"
            android:pathData="M16,25.8c1.1,0,2-0.9,2-2h-4C14,24.9,14.9,25.8,16,25.8z" />
    </group>
</vector>

XML

    <com.richpath.RichPathView
        android:id="@+id/ic_notifications"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        app:vector="@drawable/ic_notifications" />

Java

RichPath top = notificationsRichPathView.findRichPathByName("top");
RichPath bottom = notificationsRichPathView.findRichPathByName("bottom");

RichPathAnimator.animate(top)
        .interpolator(new DecelerateInterpolator())
        .rotation(0, 20, -20, 10, -10, 5, -5, 2, -2, 0)
        .duration(4000)
        .andAnimate(bottom)
        .interpolator(new DecelerateInterpolator())
        .rotation(0, 10, -10, 5, -5, 2, -2, 0)
        .startDelay(50)
        .duration(4000)
        .start();

Installation

Add the following dependency to your module build.gradle file:

dependencies {
	...
	implementation 'com.github.tarek360.RichPath:animator:0.1.1'
}

Add this to your root build.gradle file (not your module build.gradle file) :

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

More Control by the RichPathAnimator

• Animate multiple paths sequentially or at the same time

RichPathAnimator
       .animate(richPath1, richPath2)
       .rotation(value1, value2, ...)

       //Animate the same path or another with different animated attributes.
       .andAnimate(richPath3)
       .scale(value1, value2, ...)

       //Animate after the end of the last animation.
       .thenAnimate(richPath4)
       .strokeColor(value1, value2, ...)

       // start your animation 🎉
       .start();

• Which one of the paths is clicked?

richPathView.setOnPathClickListener(new RichPath.OnPathClickListener() {
    @Override
    public void onClick(RichPath richPath) {
       if (richPath.getName().equals("path_name")) {
           //TODO do an action when a specific path is clicked.
       }
    }
});

TODO

• Clickable path (Done)
• Support clip-path
• Path animation (animate a RichPath on a path)
• Reverse animation
• ...

If you have any suggestion please open an issue for it.
