how to create ripple effect for pre-lollipop

For lollipop(API>21) make file as btn_ripple_effect.xml in drawable-v21 and put below code

 <?xml version="1.0" encoding="utf-8"?>

    <ripple xmlns:android="http://schemas.android.com/apk/res/android"
        xmlns:tools="http://schemas.android.com/tools"
        android:color="?android:colorAccent"
        tools:targetApi="lollipop">
        <item android:drawable="@color/cancel_btn_clr" /> <!-- default -->
        <item android:id="@android:id/mask">
            <shape android:shape="rectangle">
                <solid android:color="?android:colorAccent" />
            </shape>
        </item>
    </ripple>

For pre lollipop (API<21)make file as btn_ripple_effect.xml in drawable folder and put below code

<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
    <item android:state_pressed="true">
        <shape>
            <solid android:color="@color/colorAccent"></solid>
        </shape>
    </item>

    <item>
        <shape>
            <solid android:color="@color/cancel_btn_clr"></solid>
        </shape>
    </item>
</selector>

Create button as below

<Button
                    android:id="@+id/button3"
                    style="@style/cancel_btn_style"
                    android:layout_marginLeft="50dp"
                    android:text="Cancel"
                    />

Add this in your style.xml

          <style name="cancel_btn_style" parent="Theme.AppCompat">
<item name="android:textSize">15sp</item>
<item name="android:textColor">#ffffff</item>
<item name="android:layout_height">36dp</item>
<item name="android:layout_width">90dp</item>
<item name="android:background">@drawable/btn_ripple_effect</item>

You could try this library balysv/material-ripple.

In your gradle, add this line :

compile 'com.balysv:material-ripple:1.0.2'

And this is how to do it :

<com.balysv.materialripple.MaterialRippleLayout
android:id="@+id/ripple"
android:layout_width="match_parent"
android:layout_height="wrap_content">

<Button
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:layout_gravity="center"
    android:text="Button inside a ripple"/>
</com.balysv.materialripple.MaterialRippleLayout>

For lollipop(API>21) make file as btn_ripple_effect.xml in drawable-v21 and put below code

<?xml version="1.0" encoding="utf-8"?>
<ripple xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:color="#f8c7c9c8"
    tools:targetApi="lollipop">

    <item android:id="@android:id/mask">

        <shape android:shape="oval">
            <corners android:radius="@dimen/dp10" />
            <solid android:color="#f8ced6d2" />

        </shape>
    </item>
</ripple>

For pre lollipop (API<21)make file as btn_ripple_effect.xml in drawable folder and put below code

<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">

    <item android:state_pressed="true">
        <shape android:shape="oval">
            <solid android:color="#f8ced6d2"/>
        </shape>
    </item>

    <item>
        <shape>
            <solid android:color="@color/transparent"/>
        </shape>
    </item>
</selector>

use it on imageview like this

<ImageView
  android:id="@+id/imageViewOffer"
  android:layout_width="wrap_content"
  android:layout_height="wrap_content"
  android:layout_centerVertical="true"
  android:background="@drawable/btn_ripple_effect"
  android:src="@mipmap/ic_offers"/>

I know this is old but you can perform your action in onRippleCompleteListener provided by the library. Something like :

rippleView.setOnRippleCompleteListener(new RippleView.OnRippleCompleteListener() {

@Override
public void onComplete(RippleView rippleView) {
//Your code here...
}
});

Hope this helps. :)
