         builder.setTitle("友情提示");
         builder.setMessage("您确定要删除吗?");
         //确定按钮
         builder.setPositiveButton("确定", new OnClickListener() {

             @Override
             public void onClick(DialogInterface dialog, int which) {
                 //确定删除的代码
                 Toast.makeText(MainActivity.this, "删除成功", 0).show();
             }
         });
         //点取消按钮
         builder.setNegativeButton("取消", null);

         //显示对话框
         //AlertDialog dialog = builder.create();
