Ripple Effect on Android Button

The ripple effect is a touch feedback response seen on many Android UI elements, signaling that an element has been touched. Here's how you can apply a ripple effect to a button or any other view in Android:

1. Using Default Ripple Effect:

If you're okay with the default ripple effect color (which is usually a light gray), you can easily get this effect by setting the button's background to a drawable that has a ripple.

For a Button:

<Button
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:text="Click Me"
    android:background="?attr/selectableItemBackground"/>

For an ImageButton or ImageView:

<ImageButton
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:src="@drawable/your_icon"
    android:background="?attr/selectableItemBackgroundBorderless"/>

2. Using Custom Ripple Effect:

If you want a custom ripple color, you can define a custom ripple drawable.

First, create a new drawable resource file (e.g., button_ripple.xml):

<!-- res/drawable/button_ripple.xml -->
<ripple xmlns:android="http://schemas.android.com/apk/res/android"
    android:color="@color/yourRippleColor">

    <item android:id="@android:id/mask">
        <shape android:shape="rectangle">
            <solid android:color="@color/yourRippleColor" />
        </shape>
    </item>

    <item android:drawable="@color/buttonNormalColor" />

</ripple>

Then, set this drawable as the background of your button:

<Button
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:text="Click Me"
    android:background="@drawable/button_ripple"/>

Notes:

  • Custom Ripple Colors: In the example above, you'll replace @color/yourRippleColor and @color/buttonNormalColor with your desired colors.

  • Ripple Behavior: The ripple effect starts from the point of the touch event and then spreads outward. If the view has defined boundaries (like a Button), the ripple will be constrained to those boundaries. If the view doesn't have strict boundaries (like an ImageButton), using selectableItemBackgroundBorderless will let the ripple spread outside the view's bounds.

  • Minimum API Level: The ripple effect is available starting from API level 21 (Lollipop). If you're supporting earlier versions, make sure to provide alternative drawables or use conditional checks to avoid crashes on older devices.

By incorporating the ripple effect, you provide tactile feedback to users, making the UI more intuitive and aligned with modern Android design principles.
