推荐答案

在这里，您无需为无线电组和复选框实现两个不同的CheckedChangeListener.

Here you need no implement two diffrent CheckedChangeListener for radio group and checkbox.

OnCheckedChangeListener用于单选组，android.widget.CompoundButton.OnCheckedChangeListener用于复选框.

OnCheckedChangeListener is for radio group and android.widget.CompoundButton.OnCheckedChangeListener is for checkbox.

您需要实现两个不同的CheckedChangeListener

you need to implement two different CheckedChangeListener

对于无线电组和复选框，请参考下面的代码.

refer below code for both radio group and checkbox.

public class abcd extends Activity implements OnCheckedChangeListener,android.widget.CompoundButton.OnCheckedChangeListener{

    RadioGroup rd;
    CheckBox cx;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.abcd);

        rd  =  (RadioGroup) findViewById(R.id.radioGroup1);
        cx = (CheckBox) findViewById(R.id.checkBox1);

        rd.setOnCheckedChangeListener(this);
        cx.setOnCheckedChangeListener(this);


    }
    @Override
    public void onCheckedChanged(RadioGroup group, int checkedId) {

        // Here you can get your Radio button checked id
        System.out.println("radiogroup checked");

    }
    @Override
    public void onCheckedChanged(CompoundButton buttonView, boolean isChecked) {
        System.out.println("checkbox checked");

    }

}
