Android随笔之——用shell脚本模拟用户按键、触摸操作

　　之前写过两篇关于Android中模拟用户操作的博客(其实用一篇是转载的)，现在就来讲讲用shell脚本来模拟用户按键操作。本次的目标是用shell脚本打开微信并在其搜索框中搜索相关内容。

　　本文的模拟功能主要是用adb的input命令来实现，如果你adb的环境变量配置正确的话，在cmd中输入 adb shell input 就可以看见input的用法了。

usage: input ...
input text //输入文字（中文不支持）
input keyevent //keyevent按键
input [touchscreen|touchpad|touchnavigation] tap <x> <y>//点击屏幕
input [touchscreen|touchpad|touchnavigation] swipe <x1> <y1> <x2> <y2> //屏幕滑动
input trackball press //滚球已经不用了
input trackball roll //滚球已经不用了
input rotationevent 0 1->90 2->180 3->270> //顺时针旋转

下面直接上安卓用户操作的代码，就一个MainActivity而已，UI、Mainfest都不用配置(可能需要root权限)

package com.lsj.adb;

import java.io.DataOutputStream;

import android.app.Activity;
import android.os.Bundle;
import android.view.Menu;

public class MainActivity extends Activity {

private String[] search = {
"input keyevent 3",// 返回到主界面，数值与按键的对应关系可查阅KeyEvent
"sleep 1",// 等待1秒
"am start -n com.tencent.mm/com.tencent.mm.ui.LauncherUI",// 打开微信的启动界面，am命令的用法可自行百度、Google
"sleep 3",// 等待3秒
"am start -n com.tencent.mm/com.tencent.mm.plugin.search.ui.SearchUI",// 打开微信的搜索
"input text 123",// 像搜索框中输入123，但是input不支持中文，蛋疼，而且这边没做输入法处理，默认会自动弹出输入法
};

@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
//如果input text中有中文，可以将中文转成unicode进行input,没有测试，只是觉得这个思路是可行的
search[5] = chineseToUnicode(search[5]);
execShell(search);
}

/**
* 执行Shell命令
*
* @param commands
*            要执行的命令数组
*/
public void execShell(String[] commands) {
// 获取Runtime对象
Runtime runtime = Runtime.getRuntime();

DataOutputStream os = null;
try {
// 获取root权限，这里大量申请root权限会导致应用卡死，可以把Runtime和Process放在Application中初始化
Process process = runtime.exec("su");
os = new DataOutputStream(process.getOutputStream());
for (String command : commands) {
if (command == null) {
continue;
}

// donnot use os.writeBytes(commmand), avoid chinese charset
// error
os.write(command.getBytes());
os.writeBytes("\n");
os.flush();
}
os.writeBytes("exit\n");
os.flush();
process.waitFor();
} catch (Exception e) {
e.printStackTrace();
}
}

/**
* 把中文转成Unicode码
* @param str
* @return
*/
public String chineseToUnicode(String str){
String result="";
for (int i = 0; i < str.length(); i++){
int chr1 = (char) str.charAt(i);
if(chr1>=19968&&chr1<=171941){//汉字范围 \u4e00-\u9fa5 (中文)
result+="\\u" + Integer.toHexString(chr1);
}else{
result+=str.charAt(i);
}
}
return result;
}

/**
* 判断是否为中文字符
* @param c
* @return
*/
public  boolean isChinese(char c) {
Character.UnicodeBlock ub = Character.UnicodeBlock.of(c);
if (ub == Character.UnicodeBlock.CJK_UNIFIED_IDEOGRAPHS
|| ub == Character.UnicodeBlock.CJK_COMPATIBILITY_IDEOGRAPHS
|| ub == Character.UnicodeBlock.CJK_UNIFIED_IDEOGRAPHS_EXTENSION_A
|| ub == Character.UnicodeBlock.GENERAL_PUNCTUATION
|| ub == Character.UnicodeBlock.CJK_SYMBOLS_AND_PUNCTUATION
|| ub == Character.UnicodeBlock.HALFWIDTH_AND_FULLWIDTH_FORMS) {
return true;
}
return false;
}

}

效果图:
