之前寫過兩篇關於Android中模擬用戶操作的博客(其實用一篇是轉載的),現在就來講講用shell腳本來模擬用戶按鍵操作。本次的目標是用shell腳本打開微信並在其搜索框中搜索相關內容。
本文的模擬功能主要是用adb的input命令來實現,如果你adb的環境變量配置正確的話,在cmd中輸入 adb shell input 就可以看見input的用法了。
usage: input ...
input text //輸入文字(中文不支持)
input keyevent //keyevent按鍵
input [touchscreen|touchpad|touchnavigation] tap <x> <y>//點擊屏幕
input [touchscreen|touchpad|touchnavigation] swipe <x1> <y1> <x2> <y2> //屏幕滑動
input trackball press //滾球已經不用了
input trackball roll //滾球已經不用了
input rotationevent 0 1->90 2->180 3->270> //順時針旋轉
下面直接上安卓用戶操作的代碼,就一個MainActivity而已,UI、Mainfest都不用配置(可能需要root權限)</span>
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,數值與按鍵的對應關係可查閱KeyEvent
"sleep 1",// 等待1秒
"am start -n com.tencent.mm/com.tencent.mm.ui.LauncherUI",// 打開微信的啓動界面,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",// 打開微信的搜索
"input text 123",// 像搜索框中輸入123,但是input不支持中文,蛋疼,而且這邊沒做輸入法處理,默認會自動彈出輸入法
};
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
//如果input text中有中文,可以將中文轉成unicode進行input,沒有測試,只是覺得這個思路是可行的
search[5] = chineseToUnicode(search[5]);
execShell(search);
}
/**
* 執行Shell命令
*
* @param commands
* 要執行的命令數組
*/
public void execShell(String[] commands) {
// 獲取Runtime對象
Runtime runtime = Runtime.getRuntime();
DataOutputStream os = null;
try {
// 獲取root權限,這裏大量申請root權限會導致應用卡死,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();
}
}
/**
* 把中文轉成Unicode碼
* @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){//漢字範圍 \u4e00-\u9fa5 (中文)
result+="\\u" + Integer.toHexString(chr1);
}else{
result+=str.charAt(i);
}
}
return result;
}
/**
* 判斷是否爲中文字符
* @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;
}
}
模擬用戶打開微信,並進行搜索就這麼完成了。其實這裏用shell命令模擬用戶操作還是有些問題的,比如說控件長按(sendevent),好難理解,而且需要跟其中傳遞的控件座標參數應該要跟屏幕分辨率聯繫起來,實際應用範圍不是很廣泛。PS:那種大量需要重複操作的除外,如:自動化測試,遊戲刷圖(PS:騰訊的仙劍手遊把我大仙劍毀了啊,麻花騰你妹啊,你全家都是麻花騰)。
最後,其實可以參考下按鍵精靈,這款應用做的還不錯,除了不給root權限就崩外....
補充:以上模擬用戶操作的代碼在交互不頻繁的情況下是完全沒有問題的,但是如果使用頻繁的話,會發生多次申請root權限,導致系統卡死的現象,後面在google上找到了一個開源項目,可以解決這個問題(它使用的是單例模式),代碼如下:
