Java 需要在警报框对话框中创建行空格

这是我的密码：

public void create_dialoginfo()
    {
        AlertDialog.Builder alert = new AlertDialog.Builder(main.this);
        alert.setTitle("911 Info");
        alert.setMessage(
                "Button Description: " +
                "" +
                "1. Calls 911 " +
                "2. Sends GPS Cordinates to Contact " +
                "3. Activates a monitored call " +
                "4. Activates alarm and captures images to web for viewing");
        alert.setPositiveButton("Ok", new DialogInterface.OnClickListener() 
        {   
            public void onClick(DialogInterface dialog, int which) 
            {
                // TODO Auto-generated method stub  
            }
        });
        alert.create();
        alert.show();
    }

警报框已创建，但没有行间距，您使用什么来创建行间距？

使用\n作为下一行

AlertDialog.Builder alert = new AlertDialog.Builder(this);
            alert.setTitle("911 Info");
            alert.setMessage("Button Description: \n1. Calls 911\n2. Sends GPS Cordinates to Contact\n3. Activates a monitored call\n4. Activates alarm and captures images to web for viewing");
            alert.setPositiveButton("Ok",
                    new DialogInterface.OnClickListener() {
                        public void onClick(DialogInterface dialog, int which) {
                            // TODO Auto-generated method stub
                        }
                    });
            alert.create();
            alert.show();

您不应该只使用“linex中的文本”\n“其中“\n”更改为新行字符吗？等式“3.激活受监控的呼叫\n”。
