android 显示单选列表对话框 builder.setSingleChoiceItems

**通过AlertDialog.Builder类的setSingleChoiceItems方法可以创建带单按钮的列表：方法如下：**

1、从资源文件中装载数据：

public Builder setSingleChoiceItems(int itemsId, int checkedItem, final OnClickListener listener)

2、从数据集中装载数据

public Builder setSingleChoiceItems(Cursor cursor, int checkedItem, String labelColumn, final OnClickListener listener)

3、从字符串数组中装载数据

public Builder setSingleChoiceItems(CharSequence\[\] items, int checkedItem, final OnClickListener listener)

4、从ListAdapter对象中装载数据

public Builder setSingleChoiceItems(ListAdapter adpater, int checkedItem, final OnClickListener listener)
