shell/批处理脚本将命令定向到 adb shell [英] shell/ batch scripting to direct commands to adb shell

问题描述

我正在尝试为 linux 编写批处理(用于 win)和 shell 脚本，以在 android UI 上自动执行按键和触摸事件.目前在 Windows 批处理文件中，我正在为每个事件启动一个 adb shell，例如

I am trying to write a batch(for win) and a shell script for linux to automate key and touch events on a android UI. At the moment in a windows batch file I am starting a adb shell for each event for eg

    :again

adb shell am start -a android.intent.action.MAIN -n com.q.me.fui.activity/.InitActivity

sleep 15

adb shell sendevent /dev/input/event0 3 0 281
adb shell sendevent /dev/input/event0 3 1 70
adb shell sendevent /dev/input/event0 1 330 1
adb shell sendevent /dev/input/event0 0 0 0
adb shell sendevent /dev/input/event0 1 330 0
adb shell sendevent /dev/input/event0 0 0 0   
adb shell sendevent /dev/input/event0 1 330 1
adb shell sendevent /dev/input/event0 0 0 0
adb shell sendevent /dev/input/event0 1 330 0
adb shell sendevent /dev/input/event0 0 0 0
adb shell sendevent /dev/input/event0 0 0 0
adb shell sendevent /dev/input/event0 0 0 0   

sleep 5

adb shell input keyevent 82
adb shell input keyevent 20
adb shell input keyevent 20
adb shell input keyevent 22
adb shell input keyevent 22
adb shell input keyevent 22
adb shell input keyevent 66

sleep 5

goto again

上面的代码实际上是每次启动一个新的 adb shell.我想避免这种情况.我希望我的批处理脚本只启动一次 adb shell，我想将 sendevent 和其他命令路由到子 shell，即 adb shell.

The above code is infact starting a new adb shell each time. I want to avoid this. I want my batch script to start the adb shell only once and I would like to route the sendevent and other commands to the subshell, ie the adb shell.

知道如何在 win 批处理和 Lin shell 脚本中执行此操作吗?

Any idea how I can do this in win batch and Lin shell script?

推荐答案

我不太了解批处理脚本或 shell 脚本，但我能够快速编写一个 Java 程序来执行此操作:

I don't know much about batch scripting or shell scripting, but I was able to quickly write a java program to do this:

import java.io.InputStream;
import java.io.OutputStream;
import java.io.IOException;

public class AndroidShell  {
   private ProcessBuilder builder;
   private Process adb;
   private static final byte[] LS = "
".getBytes();

   private OutputStream processInput;
   private InputStream processOutput;

   private Thread t;

   /**
    * Starts the shell 
    */
   public void start() throws IOException  {
      builder = new ProcessBuilder("adb", "shell");
      adb = builder.start();

      // reads from the process output
      processInput = adb.getOutputStream();

      // sends to process's input
      processOutput = adb.getInputStream();

      // thread that reads process's output and prints it to system.out
      Thread t = new Thread() {
         public void run() {
            try   {
               int c = 0;
               byte[] buffer = new byte[2048];
               while((c = processOutput.read(buffer)) != -1) {
                     System.out.write(buffer, 0, c);
               }
            }catch(Exception e)  {}
         }
      };
      t.start();
   }

   /**
    * Stop the shell;
    */
   public void stop()   {
      try   {
         if(processOutput != null && t != null) {
            this.execCommand("exit");
            processOutput.close();
         }
      }catch(Exception ignore)  {}
   }

   /**
    * Executes a command on the shell
    * @param adbCommand the command line.
    * e.g. "am start -a android.intent.action.MAIN -n com.q.me.fui.activity/.InitActivity" 
    */
   public void execCommand(String adbCommand) throws IOException {
      processInput.write(adbCommand.getBytes());
      processInput.write(LS);
      processInput.flush();
   }

   public static void main(String[] args) throws Exception  {
      AndroidShell shell = new AndroidShell();
      shell.start();

      for(String arg : args)  {
         if(arg.startsWith("sleep"))   {
            String sleep = arg.split(" ")[1].trim();
            long sleepTime = Integer.parseInt(sleep) * 1000;
            Thread.sleep(sleepTime);
         }else {
            shell.execCommand(arg);
         }
      }

      shell.stop();
   }
}

然后，您可以在 shell 脚本中使用此类，因为您喜欢传递命令以在主方法中作为命令行参数执行.

You can then use this class in a shell script as you like passing the commands to execute as command line arguments in your main method.

例如下面是shell脚本:

e.g. Below is the shell script:

#!/bin/bash

java AndroidShell "am start -a android.intent.action.MAIN -n com.q.me.fui.activity/.InitActivity" 
"sleep 15" 
"sendevent /dev/input/event0 3 0 281" 
"sendevent /dev/input/event0 3 1 70" 
"sendevent /dev/input/event0 1 330 1" 
"sendevent /dev/input/event0 0 0 0" 
"sleep 10" 
"sendevent /dev/input/event0 1 330 0" 
"exit"
