Hi, i'm beginner.
the Google tutorial is a very good work, but the things to learn are many. Thanks a lot to anddev.org.

My first simple question:
if i set an image for my button, how can i change it like onPressed effect?

regards

Hi ,your image is too large. you can use ImageButton.setAdjustViewBounds(true) to adjust the image.

Thank you, but the problem is another. sorry, maybe is my homemade english..
I have an image associated with button, that's ok. When a press it, i would like that tihs image became a little more dark for example. Just for make in evidence the press action.

you can define it in xml file, you need to read the doc carefully

I haven't solve the problem, and can you tell me how to define the xml files? thanks

I am looking for the same answer. I basically have a two custom image files. One is for the default state the other is for the pressed state. What is the best way have the image change when it is pressed and when it is not.

Thanks.

I have the same problem. It's strange... there doesn't appear to be any answers on this anywhere....

Really isn't much of a help for beginners.
It is so very bizarre that no solution has been given after such a long time.

Maybe these can help you,

First read this:
http://blog.pocketjourney.com/2008/04/30/android-tutorial-image-text-only-buttons/

Second you can add a effect of the onClick like this:

thanks, but is not exactly what I meant. Examples that you linked are appropriate about keyListener, but i think that Android lacks a method onPressed() for its button.

i tried also the use of CompoundButton instead of Button, and this way seem more good approach.

I do not believe Android has a standard ImageButton, with 3/4 image states. So I believe the only sollution to make this is implement a complete ImageButton yourself. But I haven't tried making image buttons myself, so I don't know really.

Hi, i found that also exixts ImageButton.

<ImageButton android:src="@drawable/save" android:id="@+id/buttonSave" android:layout_width="wrap_content" android:layout_height="wrap_content" />

But does it have multiple images? Or is this a normal button with just an image instead of text?

no, it hasn't. But is more close to my intent, the background change at onpressed.
