1、首先ListView獲取點選事件需要設定RadioButton的焦點android:focusable=”false”
2、通過一個List集合管理所有的RadioButton，然後在點選事件中，清空所有的狀態。

private List<RadioButton> raList;
raList = new ArrayList<RadioButton>();
listView.setOnItemClickListener(new OnItemClickListener() {

    @Override
    public void onItemClick(AdapterView<?> arg0, View view, int
 
 item,
            long arg3) {
        clearCheck();
        RadioButton radioButton = (RadioButton) view.findViewById(R.id.radio_check);
        radioButton.setChecked(true);
    }
});
/**
 * 清空所有選中狀態
 */
private void clearCheck(){
    for(RadioButton radioButton : raList){
        radioButton.setChecked(false
 
);
    }
}

public View getView(int position, View convertView, ViewGroup parent) {
    convertView = inflater.inflate(R.layout.layout_alertdialog_item, null);
    TextView tv_content = (TextView) convertView.findViewById(R.id.context);
    tv_content.setText(listContent.get(position));
    RadioButton radioButton = (RadioButton) convertView.findViewById(R.id.radio_check);
    raList.add(radioButton);
    return
 
 convertView;
}

同時需要注意，此時要把RadioButton設定為不可點選。android:clickable=”false”
