android: ImageButton Not clickable - AndroidStudio

This Work fine to me.

Use This in Xml

 <ImageButton
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:id="@+id/imageButton"
        android:layout_marginBottom="48dp"
        android:onClick="AddInfo"
        android:background="@mipmap/ea_logo"
        android:layout_alignParentBottom="true"
        android:layout_centerHorizontal="true" />

Use This in Activity Class

  public void AddInfo(View view) {

///// Use Your Own code /////////

}
