RippleDrawable

This repository contains post of Android <ripple> effect for pre lollipop devices with android 14 + (ICS+)

(well, since NineOldAndroids is deprecated, this library become 14 + only, furthermore gingerbread devices is not spread now)

Features

1. XML inflating
2. Ripple supports different shapes
3. Custom drawable loader
4. Define your custom drawable tags

Implementation

Create your desirable ripple.xml in drawable/ folder

<?xml version="1.0" encoding="utf-8"?>
<ripple
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:color="@color/ripple_material_light">     <!-- ripple color -->

    <!-- for Floating Action Button -->
    <item>
        <shape android:shape="oval">
            <solid android:color="@color/accent_material_dark"/>
        </shape>
    </item>

</ripple>

Secondly we need to inflate RippleDrawable and intercept View touches see LollipopDrawablesCompat and DrawableHotspotTouch for inflating and interception sequently. Here is sample:

public class SampleActivity extends AppCompatActivity {

    private FloatingActionButton mActionButton;

      @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_sample);
        
        mActionButton = (FloatingActionButton) findViewById(R.id.fab);
        mActionButton.setBackgroundDrawable(getDrawable2(R.drawable.fab_background));
        mActionButton.setClickable(true);// if we don't set it true, ripple will not be played
        mActionButton.setOnTouchListener(
                new DrawableHotspotTouch((LollipopDrawable) mActionButton.getBackground()));
    }
    
/**
     * {@link #getDrawable(int)} is already taken by Android API
     * and method is final, so we need to give another name :(
     */
    public Drawable getDrawable2(int id){
        return LollipopDrawablesCompat.getDrawable(getResources(), id, getTheme());
    }
}

Thats it!

##Dependency

root build.gradle add a repository

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

and in application module just add

    dependencies {
            compile 'com.github.ozodrukh:RippleDrawable:2.0.0'
    }

a little bit more

you can inflate and create your own Drawableclasses, here is tips & tricks

1 extend your Drawable from LollipopDrawable

    public class LayerDrawable extends LollipopDrawable {

2 implement your own inflation

    public void inflate(Resources r, XmlPullParser parser, AttributeSet attrs, Resources.Theme theme);

3 Register your LollipopDrawable

static {   
    LollipopDrawablesCompat.registerDrawable(RippleDrawable.class, "ripple");
}

4 inflate it!

    LollipopDrawablesCompat.getDrawable(getResources(), R.drawable.custom_drawable, getTheme());
