can't set onCheckedChangeListener to RadioGroup

I've created my RadioGroup as following:

RadioGroup radioGroup = (RadioGroup)findViewById(R.id.radioGroup1);

Now I wanted to call the onCheckedChangeListener like this:

radioGroup.setOnCheckedChangeListener(new OnCheckedChangeListener() {

    public void onCheckedChanged(RadioGroup group, int checkedId) {

    }

});

First, eclipse suggests me to write it like this, but when having typed it all out, Eclipse underlines my code like this:

enter image description here

the .setOnCheckedChangeListener is red and tells me follwing: 

The method setOnCheckedChangeListener(RadioGroup.OnCheckedChangeListener) 
in the type RadioGroup is not applicable for the arguments 
(new CompoundButton.OnCheckedChangeListener(){})

Why won't my Listener work properly although eclipse first tells me to do it like this?

add the import:

 import android.widget.RadioGroup.OnCheckedChangeListener;

instead of:

 import android.widget.CompoundButton.OnCheckedChangeListener;

and your code will work like a charm :) :

RadioGroup radioGroup = (RadioGroup)findViewById(R.id.radioGroup1);    
        radioGroup.setOnCheckedChangeListener(new OnCheckedChangeListener() {   
            public void onCheckedChanged(RadioGroup group, int checkedId) {

            }
        });

the problem is that you are using:

import android.widget.CompoundButton.OnCheckedChangeListener;

You should use/import RadioGroup.OnCheckedChangeListener instead of CompoundButton.OnCheckedChangeListener:

radioGroup.setOnCheckedChangeListener(new RadioGroup.OnCheckedChangeListener() {
    @Override
    public void onCheckedChanged(RadioGroup radioGroup, int checkedId) {
        // TODO
    }
});

check your "import" section in file top. use 

"import android.widget.RadioGroup.OnCheckedChangeListener;"

instead of 

"import android.widget.CompoundButton.OnCheckedChangeListener;"
