Android Question Statelist AddState order

[Robert Valentino]

Is there a specific order required for adding to a statelist?

I had this code:

    mDDButtonStateList.Initialize
    mDDButtonStateList.AddState(mDDButtonStateList.State_Enabled, mDDArrowDown)
    mDDButtonStateList.AddState(mDDButtonStateList.State_Pressed, mDDArrowDown_Pressed)
 
    mDDButton.Background = mDDButtonStateList

In the above code, the Arrow Down showed but did not change when the button was clicked on.

So I (out of the air) swapped the two lines Pressed and Enabled (changed the order I put them in the statelist)

    mDDButtonStateList.Initialize
    mDDButtonStateList.AddState(mDDButtonStateList.State_Pressed, mDDArrowDown_Pressed)
    mDDButtonStateList.AddState(mDDButtonStateList.State_Enabled, mDDArrowDown)

    mDDButton.Background = mDDButtonStateList

And now the button works just fine. The Button shows the Arrow and when I press on it the Arrow changes to the Pressed Arrow.

I did not realize that there was any order when adding to the statelist. I just thought the .State_Pressed or .State_Enabled controlled them.

Am I experiencing a flash back to my 60's days (new those drugs would catch up with me) or is this just something I missed or forgot when looking at the user guide.

Quote from the tutorial: http://www.b4x.com/android/forum/threads/statelistdrawable-example.6589/

The StateListDrawable holds a list of states and drawables pairs. Whenever the view's state changes the list is scanned and the first item that matches the current state is chosen.

The order is important.
