先给出RadioButton的布局

<com.kuibu.jucai.widget.MyRadioGroup
        android:id="@+id/myRadioGroup"
        android:layout_width="match_parent"
        android:layout_height="wrap_content">
    
        <LinearLayout

        </LinearLayout>
    </com.kuibu.jucai.widget.MyRadioGroup>
    
    这里用到了一个自定义控件,如下

public class MyRadioGroup extends RadioGroup {
       
    
        //对外暴漏
        private OnCheckedChangeListener mOnCheckedChangeListener;
    
        public MyRadioGroup(Context context) {
       
            super(context);
        }
    
        public MyRadioGroup(Context context, AttributeSet attrs) {
       
            super(context, attrs);
        }
    
        public void setOnCheckedChangeListener(OnCheckedChangeListener listener) {
       
            mOnCheckedChangeListener = listener;
        }
    
        @Override
        public void addView(final View child, int index, ViewGroup.LayoutParams params) {
       
            if (child instanceof LinearLayout) {
       
                int childCount = ((LinearLayout) child).getChildCount();
                for (int i = 0; i < childCount; i++) {
       
                    View view = ((LinearLayout) child).getChildAt(i);
                    if (view instanceof RadioButton) {
       
                        final RadioButton button = (RadioButton) view;
                        ((RadioButton) button).setOnTouchListener(new OnTouchListener() {
       
    
                            @Override
                            public boolean onTouch(View v, MotionEvent event) {
       
                                ((RadioButton) button).setChecked(true);
                                checkRadioButton((RadioButton) button);
                                if (mOnCheckedChangeListener != null) {
       
                                    mOnCheckedChangeListener.onCheckedChanged(MyRadioGroup.this, button.getId());
                                }
                                return true;
                            }
                        });
                    }
                }
            }
    
            super.addView(child, index, params);
        }
    
        private void checkRadioButton(RadioButton radioButton) {
       
            View child;
            int radioCount = getChildCount();
            for (int i = 0; i < radioCount; i++) {
       
                child = getChildAt(i);
                if (child instanceof RadioButton) {
       
                    if (child == radioButton) {
       
                        // do nothing
                    } else {
       
                        ((RadioButton) child).setChecked(false);
                    }
                } else if (child instanceof LinearLayout) {
       
                    int childCount = ((LinearLayout) child).getChildCount();
                    for (int j = 0; j < childCount; j++) {
       
                        View view = ((LinearLayout) child).getChildAt(j);
                        if (view instanceof RadioButton) {
       
                            final RadioButton button = (RadioButton) view;
                            if (button == radioButton) {
       
                                // do nothing
                            } else {
       
                                ((RadioButton) button).setChecked(false);
                            }
                        }
                    }
                }
            }
        }
    }
    
    网络不好,无法直接插入代码,只能这样拷贝了.
