[Android] Make android button transparent.
You can make android button transparent by inserting following code in layout xml file. android:background="@android:color/transparent" For example, I used it in one of my button as following. <Button android:id="@+id/button1" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_alignParentLeft="true" android:layout_alignParentRight="true" android:layout_alignParentTop="true" android:text="Who is computer Geek?" android:background="@android:color/transparent" />
