Android 获取java.lang.IllegalStateException:在使用RadioGroup时，必须首先对子级的父级调用removeView（）

我使用RadioGroup只实现了一个项目，可以从动态创建的单选按钮中进行选择

    final LinearLayout firstRowTxtLayout = new LinearLayout(fContext);
    firstRowTxtLayout.setLayoutParams(new LinearLayout.LayoutParams(
            LinearLayout.LayoutParams.WRAP_CONTENT,
            LinearLayout.LayoutParams.WRAP_CONTENT));

    rbGroup.setLayoutParams(new LinearLayout.LayoutParams(
            LinearLayout.LayoutParams.WRAP_CONTENT,
            LinearLayout.LayoutParams.WRAP_CONTENT));
    rbButton = new RadioButton(fContext);
    rbButton.setLayoutParams(new LinearLayout.LayoutParams(
            LinearLayout.LayoutParams.WRAP_CONTENT,
            LinearLayout.LayoutParams.WRAP_CONTENT));
    rbButton.setId(rbTagincreament);
    rbGroup.addView(rbButton);

我已经在循环外部初始化了RadioGroup。并将放射组视图添加到另一个布局中

我再次更改了它，如下所示。现在我得到了单选按钮，但我可以选择组中的每个按钮

            private void createRadioButton(int num) {
    Log.i("comVisa", "Num ==" + num);

    rg = new RadioGroup(fContext); // create the RadioGroup
    rg.setOrientation(RadioGroup.HORIZONTAL);// or RadioGroup.VERTICAL

    rb = new RadioButton(fContext);
    rb.setId(num++);
    rg.addView(rb); // the RadioButtons are added to the radioGroup instead
    // of the layout
    firstRowTxtLayout.addView(rg);// you add the whole RadioGroup to the
    // layout
    rg.setOnCheckedChangeListener(new OnCheckedChangeListener() {

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


        }
    });

}

当我初始化rg=new RadioGroupfContext时；在外面，我得到：

`IllegalStateException`. You must call removeView() on the child's parent first while using RadioGroup

带有代码行的Logcat：

rbButton当前在另一个视图中，这就是异常的原因。在将其添加到rbGroup之前，必须调用\u的父项\u\rbButton.removeViewrbButton。

rbButton的父项是线性布局吗？如果是这样的话，你可能需要先浏览txtlayout.removeViewRBButton你在说什么循环？谢谢大家的精彩帖子
