Answer 1

试试这样，

首先动态创建一个ListView。

    ListView choicelist = new ListView(this);
    choicelist.setChoiceMode(ListView.CHOICE_MODE_SINGLE);
    choicelist.setAdapter(new ArrayAdapter<String>(this,
                   android.R.layout.simple_list_item_single_choice,
                   android.R.id.text1, your_answer_list));
    choicelist.setSelector(new ColorDrawable(0x0));
    choicelist.setScrollBarStyle(View.SCROLLBARS_INSIDE_OVERLAY);
    choicelist.setCacheColorHint(0);
    choicelist.setVerticalFadingEdgeEnabled(false);

最后将此列表添加到您的布局中

linearLayoutShowQues.addView(choicelist);

对于自定义，您可以使用自定义适配器。

希望这会帮助你。
