Android Radio Button

Question

Hi, I have a radio button group in Android which looks something like:

Choose Color:

• Red
• Blue
• Orange
• Green

I need to get selected radio button and also its value.

I have 4 radiobuttons in this manner within radiogroup rg

rb1a=(RadioButton)findViewById(R.id.rb1a);
rb1b=(RadioButton)findViewById(R.id.rb1b);
rb1c=(RadioButton)findViewById(R.id.rb1c);
rb1d=(RadioButton)findViewById(R.id.rb1d);
tv1=(TextView)findViewById(R.id.tv1);
next1=(Button)findViewById(R.id.next1);
rg=(RadioGroup)findViewById(R.id.rg);

// I have error after this line.please help
rg.setOnCheckedChangeListener(new OnCheckedChangeListener()
{
    public void onCheckedChanged(RadioGroup group, int checkedId)
    {

    }

    @Override
    public void onCheckedChanged(CompoundButton arg0, boolean arg1) {
        // TODO Auto-generated method stub

    }
});

hi,

like you can see on the android documentation http://developer.android.com/reference/android/widget/RadioGroup.OnCheckedChangeListener.html the OnCheckedChangeListener has only the method onCheckedChanged(RadioGroup group, int checkedId) and doesn't contain the method public void onCheckedChanged(CompoundButton arg0, boolean arg1) -> remove it and try again.

You find an example here: http://developer.android.com/guide/tutorials/views/hello-formstuff.html
