Android, Simple box inside a button?

I want to have a button like the one in the link below. How can i achieve it just by java code or xml? By the way it's going to be of a different color when pressed. I've explored similar posts but none helped. Any help appreciated.
The button which i want

Just make a View with large rectangle and add what you want(e.g. Label contains 'Number Of Students' and/or something else) in the view.
Then, add onClickListener to the View.
To change clicked colour, refer to here

Android:: Highlight a non-selected button

I am working on a game project.
I have 4 buttons on my screen. User has to select one of the 4. If user selects the correct one, it works fine. but if user selects incorrect one, I want to highlight the correct answer even though user didnt clicked it.
I have presentation due tomorrow. Can anybody point me to some example source or explain it here, as to how can I accomplish it.

You can set the correct buttons background color or image while clicking other buttons

Whenever user clicks on the incorrect button simply call :
correctButton.setPressed(true)
This will highlight the correct button as per your requirement.

you can do one thing..
Call Button.requestFocus() method to get the focus.
Create a custom selector for you Button's background. there
< item android:state_focused="true" android:drawable="#color/your_color" />

Page identicator and android

I want to do some like this:
I want to do some like on this picture. I want to change photos na have this small circles. Is in android any widget to do that?
How I can do this?

I would use a GalleryView along with a RadioGroup where each dot is a RadioButton, then you can change the radio selected when the GalleryView is changed.
You can also style the dots and make them look whatever you want.

you can use setAlpha method of imageView class to do this.
imgView.setAlpha(90);

Thats the link for adding images to show different state of buttons. You create a xml file for this and set this file as the background for the button.
