日常水文章之rk主板上的节点传参

在rk主板上,节点是用的很频繁的一个东西,在cmd命令行中使用使用echo命令传参,在安卓怎么使用呢?

   

    

     

      

     
     

      

       package com.example
      
     
    

     

      

     
     

      
 
      
     
    

     

      

     
     

      

       import android.util.Log
      
     
    

     

      

     
     

      

       import java.io.BufferedWriter
      
     
    

     

      

     
     

      

       import java.io.FileWriter
      
     
    

     

      

     
     

      
 
      
     
    

     

      

     
     

      

       class SignTypeManger {

                   WorkUpWriter =
      
     
    

     

      

     
     

      

                       BufferedWriter(FileWriter(fileName))

               }

                   Log.i(TAG,

               } 
       catch (e: Exception) {
      
     
    

     

      

     
     

      

               }
      
     
    

     

      

     
     

      

           }
      
     
    

     

      

     
     

      
 
      
     
    

     

      

     
     

      
    
       companion 
       object {
      
     
    

     

      

     
     

      
        
       var TAG = 
       "mSignTypeManger"
      
     
    

     

      

     
     

      
        
       var mSignTypeManger: SignTypeManger? = SignTypeManger()
      
     
    

     

      

     
     

      
        
       fun getSignTypeMangerr(): SignTypeManger {
      
     
    

     

      

     
     

      
            
       if (mSignTypeManger == 
       null) {
      
     
    

     

      

     
     

      

                       mSignTypeManger = SignTypeManger()
      
     
    

     

      

     
     

      

                   }
      
     
    

     

      

     
     

      
            
       return mSignTypeManger 
       as SignTypeManger
      
     
    

     

      

     
     

      

               }
      
     
    

     

      

     
     

      

           }
      
     
    

     

      

     
     

      

       }
      
     
   

调用方式:SignTypeManger.getSignTypeMangerr().sendCmdToMachine("传参", "节点地址"),注意节点需要给读写权限!
