Reasons for receiving "RadioGroup is not applicable for the arguments"

I am implementing RadioGroup in my application. For that I have imported import android.widget.RadioGroup and implemented OnCheckedChangeListener. But still I am getting this error:

The method setOnCheckedChangeListener(RadioGroup.OnCheckedChangeListener) in the type RadioGroup is not applicable for the arguments (OpenedClass)

Java:

OpenedClass.java

public class OpenedClass extends Activity implements OnClickListener,OnCheckedChangeListener{

    TextView tv1,tv2;
    RadioGroup selectionList;
    Button rtn;
    String gotBread;
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        // TODO Auto-generated method stub
        super.onCreate(savedInstanceState);
        setContentView(R.layout.send);
        initlize();
        Bundle gotBusket = getIntent().getExtras();
        gotBread = gotBusket.getString("KEY");
        tv1.setText(gotBread);

    }
    private void initlize() {
        // TODO Auto-generated method stub

        tv1 = (TextView)findViewById(R.id.tvQuestion);
        tv2 = (TextView)findViewById(R.id.textView2);
        rtn = (Button)findViewById(R.id.bReturn);
        rtn.setOnClickListener(this);
        selectionList = (RadioGroup)findViewById(R.id.rgAnswers);
        selectionList.setOnCheckedChangeListener(this);
    }
    @Override
    public void onClick(View arg0) {
        // TODO Auto-generated method stub

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

        switch(arg0.getId())
        {
        case R.id.rCrazy:
            break;
        case R.id.rSuper:
            break;
        case R.id.rBoth:
            break;
        }

    }



}

You are importing an incorrect class of OnCheckedChangeListener

During creating the oncheckedchangelistener(), specifying "new RadioGroup.OnCheckedChangeListener()" instead of just "OnCheckedChangeListener()" fixed the problem.

Adding the sample code for others reference. 

RadioGroup rdGroup = (RadioGroup) findViewById(R.id.rdbGp1);
    rdGroup.setOnCheckedChangeListener(new RadioGroup.OnCheckedChangeListener() {

        @Override
        public void onCheckedChanged(RadioGroup group, int checkedId) {
            // TODO Auto-generated method stub

        }
    });

You are importing an incorrect class of OnCheckedChangeListener for RadioGroup.

Replace:

import android.widget.CompoundButton.OnCheckedChangeListener;

with this one:

import android.widget.RadioGroup.OnCheckedChangeListener;

and fix your interface implementation as below:

@Override
public void onCheckedChanged(RadioGroup group, int checkedId) {
   switch(checkedId)
   {
      //your cases
   }
}
