I would like to change the background of all the `Buttons` in a `View`.

```
android:background="@drawable/button_red"

```

And i would like to do this in an `OnClick()` event.

```
android:onClick="ChangeCouleur"

```

I would like to do this in a `foreach` loop, but i am not sure how to do this.

For example:

```
for( b in ... )
    if (b.getid()!=idofthebutton)
         b.setbackgroud(button_red)

```

Thanks for any help!
