Question

目前我正在尝试将Java编码转换为Android studio。这是原始代码

    public static void main(String[] args)
    {
        ModbusClient modbusClient = new ModbusClient("192.168.1.106",502);
        try
        {
            modbusClient.Connect();
            modbusClient.WriteSingleCoil(0, true);
            modbusClient.WriteSingleRegister(0, 1234);
            modbusClient.ConvertFloatToTwoRegisters((float) 123.56));

        }
        catch (Exception e)
        {       
        }   
}

这是Android Studio中已编辑的版本：

public class medusaTest extends Activity {

    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_mb);
        Button b = (Button)this.findViewById(R.id.btn1);
        b.setOnClickListener(new Button.OnClickListener(){
            public void onClick(View v)  {
                ModbusClient modbusClient = new ModbusClient("192.168.1.106",502);
                try
                {
                    modbusClient.Connect();
                    modbusClient.WriteSingleCoil(0, true);
                    modbusClient.WriteSingleRegister(0, 1234);
                    modbusClient.WriteMultipleRegisters(11, ModbusClient.ConvertFloatToTwoRegisters((float) 123.56));
                    //System.out.println(modbusClient.ReadCoils(0, 1)[0]);
                    //System.out.println(modbusClient.ReadHoldingRegisters(0, 1)[0]);
                    //System.out.println(ModbusClient.ConvertRegistersToFloat(modbusClient.ReadHoldingRegisters(11, 2)));
                }
                catch (Exception e)
                {
                }
            }
        });

    }
    }

问题是，每当我试图在Android上运行它时，它就会一直停止应用程序。请给我建议并帮助我在Android中运行此代码。谢谢

Answer 1

确保将互联网权限添加到manifest.xml文件中。

<uses-permission android:name="android.permission.INTERNET" />

Answer 2

我设法找到了我的问题的答案。解决方案

在公共类

中的Setcontentview（R.Layout.main_activity）之后添加代码

代码：

    if (android.os.Build.VERSION.SDK_INT > 9) {
        StrictMode.ThreadPolicy policy = new StrictMode.ThreadPolicy.Builder().permitAll().build();
        StrictMode.setThreadPolicy(policy);
    }

我的问题已经解决了。感谢
