Question

Hello I’m working on android app, and I have several radio button on my app and when I click the radio button it can do what I want which is show a web page, but when I click another radio button it acts as a check box. Here is my code :

RadioButton webss = (RadioButton) findViewById (R.id.studentsite);
    RadioButton webst = (RadioButton) findViewById (R.id.staffsite);
    RadioButton webbaak = (RadioButton) findViewById (R.id.baak);
webss.setOnClickListener(new RadioButton.OnClickListener()
    {
        public void onClick(View v)
            {
            callintent(v);
            }
    });

    webst.setOnClickListener(new RadioButton.OnClickListener()
    {
        public void onClick(View v)
            {
            callintent(v);
            }
    });

    webbaak.setOnClickListener(new RadioButton.OnClickListener()
    {
        public void onClick (View v)
            {
            callintent(v);
            }
    });
public void callintent(View view) 
{
    Intent intent = null;
    switch (view.getId())
    {
        case R.id.studentsite:
            intent = new Intent(Intent.ACTION_VIEW,
            Uri.parse("http://studentsite.gunadarma.ac.id"));
            startActivity(intent);
            break;
        case R.id.staffsite:
            intent = new Intent(Intent.ACTION_VIEW,
            Uri.parse("http://staffsite.gunadarma.ac.id"));
            startActivity(intent);
            break;
        case R.id.baak:
            intent = new Intent(Intent.ACTION_VIEW,
            Uri.parse("http://baak.gunadarma.ac.id"));
            startActivity(intent);
            break;
default:
            break;
    }

do you have any to fix those code? Thanks.

Answer 1

You need to put all of your RadioButtons in your layout file inside a RadioGroup
This way whenever one is checked, the others are automatically unchecked.
