9 Step Guide To Create Ripple View Effect In Android

1

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.

Material Design Example

Goal Of Material Design

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.

How to createRipple View Effect


http://theninehertz.com/mobile-application-development

5


Create a new Android project in Eclipse by clicking on

File > New > Android Application Project.

Step1

In this tutorial you will learn how ripple effect can make your application attractive and how to develop it.

Let’s get started

6


Set the below string values to file string.xml placed under

res > values. strings.xml

Step2

<?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.

7


Now find the dimense.xml file located under

res > values, add the below values. dimens.xml

Step3

<resources>  <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.

8


To set the color and shape of buttons, set the below values in card_bk.xml file located under

res > drawable.cards_bk.xml

Step4

<?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.

Step5

Import the library RippleView in eclipse, which is located in the source code. It provides all the APIs that are necessary to create ripple effects in buttons.

Add this Ripple view library to your Android application by navigating Properties > Android > Add > RippleView. Click apply and then OK.

Step6

10


Now open the layout file (ripple_view.xml) & write the below code.

This will create a simple layout with RippleViewButton.

Step7

<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>

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(); } }); } }

11


Make some changes in main activity class

(RippleViewActivity.java)

Step8

12


Run the project to see the ripple effect in button & you are good to go.

Now you will be able to see a button with ripple view effect.

Step9
