Simple animation for floating action button in android?

Question

I need a very simple explanation of how I can animate this 'add to cart' FloatingActionButton whenever it's clicked. All I want is a smooth 'left-right' or 'down-up' movement animation.

Please look at the code below

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    android:orientation="vertical"
    android:weightSum="1"
    android:background="@color/cardview_light_background">    

    <android.support.design.widget.CoordinatorLayout
        android:id="@+id/main_content"
        android:layout_width="match_parent"
        android:layout_height="match_parent">

        <android.support.design.widget.FloatingActionButton
            android:layout_width="54dp"
            android:layout_height="54dp"
            android:layout_gravity="bottom|right"
            android:src="@mipmap/ic_add_shopping_cart_black_24dp"
            android:layout_marginBottom="40dp"
            android:layout_marginRight="30dp"
            app:backgroundTint="@android:color/holo_blue_light" />

    </android.support.design.widget.CoordinatorLayout>
</LinearLayout>

Thank you in advance!

Answer 1

Try AndroidViewAnimations library. This library provide easy way to animate you views. There is lot of effects. For example

YoYo.with(Techniques.Tada)
.duration(700)
.playOn(findViewById(R.id.edit_area));

Answer 2

floatingActionButton.animate().xBy(10).yBy(10);

On its onClick ! give coordinates as you want!

or

shake.xml > res/anim/shake.xml ( no extra library need you can customize this xml )

<set xmlns:android="http://schemas.android.com/apk/res/android">
    <translate android:duration="150"
        android:fromXDelta="-10%"
        android:repeatCount="5"
        android:repeatMode="reverse"
        android:toXDelta="10%"/>
</set>

..

final FloatingActionButton floatingActionButton = (FloatingActionButton) findViewById(R.id.fab);
floatingActionButton.setOnClickListener(new View.OnClickListener() {
    @Override
    public void onClick(View v) {
        Animation anim = android.view.animation.AnimationUtils.loadAnimation(floatingActionButton.getContext(),  R.anim.shake);
        anim.setDuration(200L);
        floatingActionButton.startAnimation(anim);
    }
});

Take a look at this:

https://github.com/Scalified/fab

It has a left to right or top to bottom Moving animation

In your gradle:

    dependencies {
    compile 'com.scalified:fab:1.1.3'
}

in layout:

    <RelativeLayout 
        xmlns:android="http://schemas.android.com/apk/res/android"
        xmlns:fab="http://schemas.android.com/apk/res-auto"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        >
        <com.scalified.fab.ActionButton 
            android:id="@+id/action_button"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:layout_alignParentBottom="true" 
            android:layout_alignParentRight="true"
            android:layout_marginRight="@dimen/fab_margin"
            android:layout_marginBottom="@dimen/fab_margin"
            />
</RelativeLayout>

Now for moving use:

 // And then find it within the content view:
ActionButton actionButton = (ActionButton) findViewById(R.id.action_button);
// Initialize the moving distance
int distance = 100.0f // in density-independent pixels

// Move ActionButton left
actionButton.moveLeft(distance);

// Move ActionButton up
actionButton.moveUp(distance);

// Move ActionButton right
actionButton.moveRight(distance);

// Move ActionButton down
actionButton.moveDown(distance);
