该程序可实现设置打印机参数，打印机使用socket与手机通讯
设置对方参数页面：
PC端依然用调试工具测试
接下来可以跟我一起操作
下载该jar包以后复制到libs中，并右键加入库中

注意在MainActivity.java中，我使用handler跳转，因为涉及到网络操作，所以我将所有的点击事件都放在线程中，我在第二个按钮中设置了跳转，然后到handler中执行，可以使用Ctrl键+F查看handler的操作

SettingLabelParametersActivity.java中用了无数个输入框，用于输入参数，如果为空就使用默认的
setting_label_parameters_layout.xml也没什么特别的

android:layout_width="match_parent"
android:layout_height="wrap_content"

SettingLabelParametersActivity.java中要注意的是，获取从第一个activity中得到的IP和port，其实TscEthernetDll这个参数只不过是用来连接端口和发送指令的用，在第一个活动释放以后第二个活动连接也是可以的，而且打印机的指令接收也只需要一条一条过去就行，像命令行一样，过去了它就存在打印机ROM（或者flash）中，如果你什么都不做，直接发送打印指令，就会沿用以前的参数，至于获取输入框数据和检测空，基本操作就不多说了
