AlertDialog的简单使用

				//创建AlertDialog
                AlertDialog.Builder builder=new AlertDialog.Builder(MainActivity.this);
                //设置标题
                builder.setTitle("....");
                //设置内容
                builder.setMessage("哒哒哒");
                //确定按钮
                builder.setPositiveButton("确定", new DialogInterface.OnClickListener() {
                    @Override
                    public void onClick(DialogInterface dialog, int which) {
                        data.remove(position);
                        listAdapter.notifyDataSetChanged();
                    }
                });
                //取消按钮
                builder.setNegativeButton("取消",null);
                //设置展示
                builder.show();
