    Answer it

    I am a newbie developer to android. I am trying to develop an application as a test run it is a Q and A app.

    Can anyone help me with the following problem.

    The pages have 2 radio buttons in a radio group, the center of the page has an image, and a few buttons(Next, Previous, Home) at the bottom. The part I need help with is when a user clicks on a radio button the image needs to disappear and the answer (Text) needs to appear in a scroll text box. The app is Yes/No based so when either button is clicked the image need to disappear and text needs to replace it.

    Thank you in advance.

  • First you need to implement onCheckedChange listener on the radio group from which you can identify which radio button is clicked. Implement listener like this:-

    RadioGroup radioGroup = (RadioGroup) findViewById(R.id.yourRadioGroup);        
        radioGroup.setOnCheckedChangeListener(new OnCheckedChangeListener() 
        {
            @Override
            public void onCheckedChanged(RadioGroup group, int checkedId) {
                // checkedId is the RadioButton selected
            }
        });
    

    Now you know which radio button is checked or selected. After this simply hide the image and show the test using setVisibility method of View class.
