RadioGroup 扩展relativelayout

扩展RelativeLayout的RadioGroup

java
public class CustomRadioGroup extends RelativeLayout {
    private RadioButton selectedRadioButton;
    public CustomRadioGroup(Context context) {
        super(context);
    }
    public CustomRadioGroup(Context context, AttributeSet attrs) {
        super(context, attrs);
    }
    public CustomRadioGroup(Context context, AttributeSet attrs, int defStyleAttr) {
        super(context, attrs, defStyleAttr);
    }
    public void setOnCheckedChangeListener(final OnCheckedChangeListener listener) {
        int childCount = getChildCount();
        for (int i = 0; i < childCount; i++) {
            View view = getChildAt(i);
            if (view instanceof RadioButton) {
                final RadioButton radioButton = (RadioButton) view;
                radioButton.setOnClickListener(new OnClickListener() {
                    @Override
                    public void onClick(View v) {
                        if (selectedRadioButton != null) {
                            selectedRadioButton.setChecked(false);
                        }
                        radioButton.setChecked(true);
                        selectedRadioButton = radioButton;
                        if (listener != null) {
                            listener.onCheckedChanged(CustomRadioGroup.this, radioButton.getId());
                        }
                    }
                });
            }
        }
    }
    public interface OnCheckedChangeListener {
        void onCheckedChanged(CustomRadioGroup group, int checkedId);
    }
}
