Android UI How to - ImageButton with transparent background

• Back to Button  ↑

You can specify a transparent background for the image button.

The result will be a clickable image that acts like a button but can look like whatever you want it to look like.

Just set android:background="@null" for the image button.

Example

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:orientation="vertical">
/*  w w  w.  j a  va 2 s. co  m*/
<ImageButton
    android:id="@+id/image3"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:background="@null" />
</LinearLayout>
