在Android单选按钮列表，爪哇 [英] List of RadioButtons on Android, Java

问题描述

我需要创建单选按钮列表，但如果我试图用的ListView做的比我可以同时选择所有的单选按钮，但我需要1选择单选按钮同步。因此，我可以试试这个code：

I need create a list of RadioButtons, but if I try to do it with ListView than I can select all radiobuttons simultaneously, but I need 1 selected radiobutton simultaneously. Therefore, I can try this code:

RadioGroup group=new RadioGroup(this);
LinearLayout layout=(LinearLayout)findViewById(R.id.linearLayout2);

for (String item:mMusicData.keySet()) {
    RadioButton button=new RadioButton(this);
    button.setText(item);
    group.addView(button);
}

layout.addView(group);

但布局不显示所有项目，因版面很小。我需要滚动条或其他的意思是我的任务。请帮帮我。

But layout doesn't show all items, because layout is small. I need scrollbar or another mean for my task. Help me please.

推荐答案

您应该设置你的的ListView 到单模式。对于这种添加安卓choiceMode =singleChoice来布局包含您的的ListView ：

You should set your ListView to single mode. For this add android:choiceMode="singleChoice" to layout that contains your ListView:

 <ListView ... android:choiceMode="singleChoice" />
