将字符串数组作为数据源以列表方式显示在对话框中

　　使用AlertDialog.Builder.setItems方法可以将一个String数组以列表形式显示在对话框中，代码：

  String provinces[]=             "辽宁省"," 山东省"," 河北省"," 福建省"," 广东省", "黑龙江省"," 浙江省","吉林省"    
           AlertDialog.Builder builder= AlertDialog.Builder(         builder.setTitle("选择省份"         builder.setItems(provinces,                 onClick(DialogInterface dialog,                  builder.setMessage("您选择了："+which+":"+              
          builder.create().show();

　　效果如下图：

　

　　使用AlertDialog.Builder.setSingleChoiceItems方法不仅可以在对话框上显示列表，还可以在列表项后面显示选项按钮。代码：

  String provinces[]= String[]{
             "辽宁省"," 山东省"," 河北省"," 福建省"," 广东省", "黑龙江省"," 浙江省","吉林省"    
           AlertDialog.Builder builder= AlertDialog.Builder(         builder.setTitle("选择省份"         builder.setSingleChoiceItems(provinces, -1,              
                onClick(DialogInterface dialog,                  builder.setMessage("您已选择了："+which+":"+           
         builder.setPositiveButton("关闭",  
                onClick(DialogInterface dialog,                
          builder.create().show();

　　效果图如下：
