android– 使用字符串数组动态创建RadioButton

概述我试图从字符串数组创建RadioButton,但如果我只使用字符串它不工作,那么它似乎工作正常LogCat显示错误“ava.lang.IllegalStateException：指定的子节点已经有父节点.您必须首先在子节点的父节点上调用removeView().”我知道错误即将来临,因为RadioButton对象不是动态创建,因此显

我试图从字符串数组创建Radiobutton,但如果我只使用字符串它不工作,那么它似乎工作正常
Log Cat显示错误“ava.lang.IllegalStateException：指定的子节点已经有父节点.您必须首先在子节点的父节点上调用removeVIEw().”

我知道错误即将来临,因为Radiobutton对象不是动态创建,因此显示错误

我从这里获取代码作为参考,请检查此网址
http://android.okhelp.cz/create-radiobutton-radiogroup-dynamically-android-sample/

请检查代码并纠正我,以便我进一步使用我的应用程序
这是代码

linearLayout layout = (linearLayout) findVIEwByID(R.ID.layout);RadioGroup radioGroup = new RadioGroup(this);linearLayout.LayoutParams p = new linearLayout.LayoutParams(                linearLayout.LayoutParams.FILL_PARENT,                linearLayout.LayoutParams.WRAP_CONTENT        );        // adding Radio Group        layout.addVIEw(radioGroup, p);        // creating Radio buttons Object//        Radiobutton radiobuttonVIEw = new Radiobutton(this);        String[] ab ={"1","2"};         for(int i =0; i<ab.length;i++)        {            radiobuttonVIEw.setText(ab[i]);            radioGroup.addVIEw(radiobuttonVIEw, p);            ((VIEwGroup)layout.getParent()).removeVIEw(layout);        }

和Log Cat错误

寻求帮助
谢谢

解决方法:

IllegalStateException: The specifIEd child already has a parent. You
must call removeVIEw() on the child’s parent first.

因为您在linearLayout中再次添加相同的Radiobutton实例.

在for循环中创建Radiobutton的对象：

   for(int i =0; i<ab.length;i++)    {        Radiobutton radiobuttonVIEw = new Radiobutton(this);        radiobuttonVIEw.setText(ab[i]);        radioGroup.addVIEw(radiobuttonVIEw, p);        ((VIEwGroup)layout.getParent()).removeVIEw(layout);    }   

在for循环中以避免错误.
