Make a toast if a slidingDrawer is opening?

Question

Hi I would like to make a toast whenever a slidingDrawer is opening. I would like to know how i can listen if the slidingDrawer is opening and then make the toast if it is. I have looked everywhere but couldnt find a solution to the problem. Hope some of you can help :)

i found this on developer.android but could not figure out how to use it

    public void setOnDrawerCloseListener (SlidingDrawer.OnDrawerCloseListener onDrawerCloseListener)

In your Activity where you have your SlidingDrawer, you simply attach the listener like this:

EDIT:

Added more code:

The layout.xml:

<?xml version="1.0" encoding="utf-8"?>
<SlidingDrawer xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@+id/slidingDrawer1"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:content="@+id/content"
    android:handle="@+id/handle" >

    <Button
        android:id="@+id/handle"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="Handle" />

    <LinearLayout
        android:id="@+id/content"
        android:layout_width="match_parent"
        android:layout_height="match_parent" >
    </LinearLayout>

</SlidingDrawer>

The Activity onCreate method where you set the content view of the Activity:

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.layout);

    SlidingDrawer mySlidingDrawer = (SlidingDrawer) findViewById(R.id.slidingDrawer1);
    mySlidingDrawer.setOnDrawerOpenListener(new OnDrawerOpenListener() {
        @Override
        public void onDrawerOpened() {
            Toast.makeText(getApplicationContext(), "SlidingDrawer opened!", Toast.LENGTH_SHORT).show();
        }
    });
}

Bear in mind, that the SlidingDrawer is actually deprecated in API 17 - it's discouraged to use it.
