    Smile Ecplipse Java: using radio buttons to bring new screen for diffrent options.

    Hello, I am new to java programming. I am, currently using Eclipse to create a simple android application. In my main screen I have radio buttons which would allow the user to select the option as a radio button, i also have imported TOAST so the message appears saying which option was selected. Currently user has to select the appropriate radio button as well as press btnDisplay so the message can appear saying what was selected. All I need now is that when the user selects the radio button it would bring the appropriate XML file as well as the appropriate class for each of the radio button options depending which one was selected. I am not sure how to do that. I was thinking about array list but now I am unsure if that is what I need. Any advise would be appreciated.

    Default Re: Ecplipse Java: using radio buttons to bring new screen for diffrent options.

    Carefully read the documentation for RadioButtons and Buttons. The android docs are designed to leave a bread crumb trail of things you need in place. In short:

    1) Set an onClick listener in the xml for the button
    android:onClick="btnDisplayClicked"
    2) Set an onClick listener in the xml for the radio buttons
    android:onClick="radioButtonItemSelected"
    3) Declare the radio button listener method in the activity. This is where you would do a switch on the Id of the radio button and set the result to a member variable.
    public void radioButtonItemSelected(View view) { }
    4) Declare the button listener in the activity. This is where you generate your toast based on the member variable.
    public void onRadioButtonClicked(View view) { }

    There are of course a lot of different ways you can go about this such as programatically defining the UI and listeners but this is the simplest to get started.
