android – 使用字符串数组动态创建RadioButton

大佬教程收集整理的这篇文章主要介绍了android – 使用字符串数组动态创建RadioButton，大佬教程大佬觉得挺不错的，现在分享给大家，也给大家做个参考。

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:

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.
