Button setPressed() onClick
===

this is an easy question,

in my xml file i have :

    <Button
    android:id="@+id/button_8"
    android:layout_width="0dp"
    android:layout_height="wrap_content"
    android:text="@string/Bf"
    android:background="@drawable/button_purple" 
    android:layout_weight="1"
    android:textColor="#ffffff"
    android:onClick="action"		    
    />

And in my activity i have that :

    public void action (View v)
    {
    	s = "m";
    	changeCouleur("blue");
    	v.setPressed(true);
    }

When i pressed the button it's working but the button don't stay pressed.

Thanks in advance if you noticed something wrong.
