AlertDialog对话框的简单使用

AlertDialog.Builder builder = new AlertDialog.Builder(context);        builder.setTitle("标题");        builder.setMessage("提示内容");        builder.setCancelable(false);        builder.setPositiveButton("确定",            new DialogInterface.OnClickListener() {                @Override                public void onClick(DialogInterface dialog, int which) {                }            });        builder.setNegativeButton("取消", new DialogInterface.OnClickListener() {            @Override            public void onClick(DialogInterface dialog, int which) {                            }        });        builder.show();
