使用字符串数组动态创建RadioButton

我正在尝试从字符串数组创建RadioButton，但如果我仅使用字符串，它就不起作用，那么它似乎工作正常 Log Cat 显示错误“ava.lang.IllegalStateException：指定的子项已经有父项。您必须首先在子项的父项上调用removeView()。”

我知道会出现错误，因为 RadioButton 对象不是动态创建的，因此会显示错误

我从这里获取了代码作为参考，请检查这个网址http://android.okhelp.cz/create-radiobutton-radiogroup-dynamically-android-sample/ 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);
        }

并记录 Cat 错误

寻求帮助 谢谢

如果你有这个数组：-

String route[] = {"1", "3", "4"};

您可以使用循环创建单选按钮：-

for (int i = 0; i < route.length; i++) 
{
    RadioButton radioButton = new RadioButton(this);
    radioButton.setText("Route " + String.valueOf(route[i]));
    radioButton.setId(i);
    rprms = new RadioGroup.LayoutParams(RadioGroup.LayoutParams.WRAP_CONTENT, RadioGroup.LayoutParams.WRAP_CONTENT);
    rgp.addView(radioButton, rprms);
}

您可以使用以下方式获取所选字段：- （我有“保存”按钮，因此此代码是在 onClick 侦听器中编写的） 否则你也可以使用 onCheckedChangeListener 。

int selection = rgp.getCheckedRadioButtonId();
for (int i = 0; i < route.length; i++) 
{
    if (i == selection)
        showToast("" + route[i]);
}
