One of the primary changes in
Lollipop is the material design
which has completely changed the
look of android. This type of design
has given an entire new design
interface to Android 5.0 and
introduced the new techniques of
customizing the applications.
However, each version of
Android is born with some new
and unique features, but Lollipop
came up with some major
advancements which were never
seen in Android’s earlier versions
(Gingerbread, Froyo, Jelly Bean,
KitKat).

The primary goal of material design is to
create an interface that works on all
mobile devices and platforms. Material
design also allows the third party app
developers to develop their own custom
application with elegant design effects.
Material design includes various
visual effects such as shrinking,
rolling or expanding of UI
elements on touch, 3D
appearance of buttons, animated
buttons, shadow effects, etc.
These effects not only provide the
attractive look to applications, but
also creates a better user
experience.

4. If you are using Lollipop version in your smartphone, then
you must have seen expanding or rolling effects in buttons
on touch events. These effects are called Ripple Effects. It
is the type of transition that happens when a user interacts
with buttons.

developers have started to implement the various design effects in their
Android applications. Among all the design effects ripple view effect
gives the most elegant and exclusive look to an application. If you are
also a mobile app developer and want to make your Android
application more attractive by using ripple effect, then follow these 9

Ripple View Effect
9 Step Guide To Create Ripple View Effect In Android

9 Step Guide To Create Ripple View Effect In Android
Create a new Android project in Eclipse by clicking on
File > New > Android Application Project.
Step 1
In this tutorial you will learn how ripple
effect can make your application attractive
and how to develop it.
Let’s get started

7. 6
9 Step Guide To Create Ripple View Effect In Android
Set the below string values to file string.xml placed under
res > values. strings.xml
Step 2
<?xml version="1.0" encoding="utf-8"?>
<resources>
<string name="app_name">RippleViewExample</string>
<string name="hello_world">Hello world!</string>
<string name="action_settings">Settings</string>
<string name="click_me">Click Me</string>
</resources>
This file is used to save your time that could be consumed in
hardcoded values. For example, let’s assume that a title string is
used in every file of the application and after creating half of
the files you want to make a slight change in title. Now, it will
be very typical to make changes in all the files, but with
String.xml file, the change needs to be done only at one place
and that is in the xml file.

8. 7
9 Step Guide To Create Ripple View Effect In Android
Now find the dimense.xml file located under
res > values, add the below values. dimens.xml
Step 3
<resources>
<!-- Default screen margins, per the Android Design
guidelines.-->
<dimen name="activity_horizontal_margin">16dp</dimen>
<dimen name="activity_vertical_margin">16dp</dimen>
</resources>
This file is used to set the values of dimensions so that the
application layout is adjusted automatically on each screen size.
In this file you can specify various dimensions like padding,
radius, width, text size etc.
To set the dimensions, there are many units available such as pt
(point), in (inches), px (pixels) but the preferred unit is dp
(density independent pixels) because dp adjust the layout of the
application on the screen size of all densities.

9. 8
9 Step Guide To Create Ripple View Effect In Android
To set the color and shape of buttons, set the below values in
card_bk.xml file located under
res > drawable.cards_bk.xml
Step 4
<?xml version="1.0" encoding="utf-8"?>
<layer-list
xmlns:android="http://schemas.android.com/apk/res/android">
<item android:left="1.2dp">
<shape android:shape="rectangle"
android:dither="true">
<corners android:radius="2.9dp"/>
<solid android:color="#ccc" />
</shape>
</item>
<item android:bottom="1.6dp">
<shape android:shape="rectangle"
android:dither="true">
<corners android:radius="3dp" />
<solid android:color="@android:color/white" />
</shape>
</item>
</layer-list>
You can also choose different colors and shapes for buttons according
to the background of your Android application.

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
xmlns:ripple="http://schemas.android.com/apk/res/org.ninehertz.rippleview.sample"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="#d2d2d2"
android:paddingBottom="@dimen/activity_vertical_margin"
android:paddingLeft="@dimen/activity_horizontal_margin"
android:paddingRight="@dimen/activity_horizontal_margin"
android:paddingTop="@dimen/activity_vertical_margin"
tools:context="org.ninehertz.rippleview.sample.RippleViewActivity" >
<org.ninehertz.rippleviewlib.RippleView
android:id="@+id/btn"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_centerInParent="true"
android:background="@drawable/card_bk"
android:gravity="center"
android:padding="35dp"
android:text="@string/click_me"
android:textAppearance="?android:attr/textAppearanceMedium"
ripple:alphaFactor="0.7"
ripple:hover="true"
ripple:rippleColor="#58FAAC" />
</RelativeLayout>

12. package org.ninehertz.rippleview.sample;
import android.app.Activity;
import android.os.Bundle;
import android.view.Menu;
import android.view.MenuItem;
import android.view.View;
import android.widget.Toast;
import org.ninehertz.rippleviewlib.RippleView;
public class RippleViewActivity extends Activity {
RippleView mButton;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.ripple_view);
mButton = (RippleView) findViewById(R.id.btn);
mButton.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
Toast.makeText(getApplicationContext(), "Ripples", Toast.LENGTH_LONG).show();
}
});
}
}
