Android button hover event

Question

I use a XML file to display a button with 2 states (normal, pressed). How can I find out when the button is pressed? Is there an event like onClick --> onPressed or how can I find it out?

Here is the XML file I use:

<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android" >
    <item android:state_focused="true" android:state_pressed="false" android:drawable="@drawable/buttonbluepressed" />
    <item android:state_focused="true" android:state_pressed="true" android:drawable="@drawable/buttonbluepressed" />
    <item android:state_focused="false" android:state_pressed="true" android:drawable="@drawable/buttonbluepressed" />
    <item android:drawable="@drawable/buttonblue"/>
</selector>

And here is how I use it:

<Button
    android:id="@+id/button_choose"
    android:layout_width="fill_parent"
    android:layout_height="wrap_content"
    android:layout_weight="1"
    android:background="@drawable/choose_button"
    android:onClick="onButtonClicked"
    android:text="@string/button_choose" />

you can use setOnTouchListener as:

button.setOnTouchListener(new OnTouchListener() {

            @Override
            public boolean onTouch(View v, MotionEvent event) {
                if(event.getAction() == MotionEvent.ACTION_DOWN){
                    //Button Pressed
                }
                if(event.getAction() == MotionEvent.ACTION_UP){
                     //finger was lifted
                }
                return false;
            }
        });
