Android实现钉钉自动打卡功能的教程_F11 - 专业站长和开发者的学习网站

首先我们需要一直不用的Android手机，插上公司的电源。下载安装钉钉并设置为极速打卡。

自动打开

我们只需要启动一个服务，定时打开钉钉应用后再返回即可。

防止熄屏

这华为手机并没有永不息屏的选项，所以我们需要设置一下防止自动息屏。

@Override
protected void onCreate(Bundle savedInstanceState) {
  super.onCreate(savedInstanceState);
  // 设置不自动息屏
  getWindow().setFlags(WindowManager.LayoutParams.FLAG_KEEP_SCREEN_ON, WindowManager.LayoutParams.FLAG_KEEP_SCREEN_ON);
  setContentView(R.layout.activity_main);
}

打开钉钉，签到后返回

核心程序

/**
   *
   * @param packageName 包名
   */
  public void openApplication(String packageName) {
    PackageManager packageManager = getPackageManager();
    PackageInfo pi = null;
    try {
      pi = packageManager.getPackageInfo(packageName, 0);
    } catch (PackageManager.NameNotFoundException e) {
    }
    Intent resolveIntent = new Intent(Intent.ACTION_MAIN, null);
    resolveIntent.addCategory(Intent.CATEGORY_LAUNCHER);
    resolveIntent.setPackage(pi.packageName);
    List<ResolveInfo> apps = packageManager.queryIntentActivities(resolveIntent, 0);
    ResolveInfo resolveInfo = apps.iterator().next();
    if (resolveInfo != null) {
      String className = resolveInfo.activityInfo.name;
      Intent intent = new Intent(Intent.ACTION_MAIN);
      intent.addCategory(Intent.CATEGORY_LAUNCHER);
      intent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
      ComponentName cn = new ComponentName(packageName, className);
      intent.setComponent(cn);
      startActivity(intent);
    }
  }

打开cmd查找钉钉的包名

adb devices

adb shell

pm list package | grep alibaba 查找阿里巴巴相关的所有包名，也可以直接pm list package查找所有包名

// 打开钉钉
String packageName = "com.alibaba.android.rimet";
          openApplication(packageName);

// 延迟2s,自动打开
try {
            Thread.sleep(2000);
          } catch (InterruptedException e) {
            e.printStackTrace();
          }

// 返回自动打卡app
String packageNameNew = "com.example.dingding";
          openApplication(packageNameNew);

创建一个service来进行自动打卡,使用java的cron4j库来执行定时任务,使用可以参见以前的博客。JFinal用cron4j执行定时任务

public class DingService extends Service {

  private final String TAG = "DingService";
  
  @Override
  public IBinder onBind(Intent intent) {
    return null;
  }

  @Override
  public void onCreate() {
    super.onCreate();

    Log.e(TAG, "Service Start!");

    ClockThread ct = new ClockThread();
    ct.start();

  }

  @Override
  public int onStartCommand(Intent intent, int flags, int startId) {
    return super.onStartCommand(intent, flags, startId);
  }

  @Override
  public void onDestroy() {
    super.onDestroy();
  }

  /**
   *
   * @param packageName 包名
   */
  public void openApplication(String packageName) {...}

  public class ClockThread extends Thread {

    public void run() {

      Scheduler scheduler = new Scheduler();
      
      //设置打开时间为工作日的 7:50,11:50,13:50,17:50
      scheduler.schedule("50 7,11,13,17 * * mon,tue,wed,thu,fri", new Thread() {
        @Override
        public void run() {

          String packageName = "com.alibaba.android.rimet";
          openApplication(packageName);

          try {
            Thread.sleep(2000);
          } catch (InterruptedException e) {
            e.printStackTrace();
          }

          String packageNameNew = "com.example.dingding";
          openApplication(packageNameNew);

        }
      });

      scheduler.start();

    }

  }
}

最后在MainActivity中启动服务即可。

随机时间

为了让打卡更加真实，每天的打卡时间尽可能尽量不一样。我们用一个Scheduler(调度任务)每天在固定时间如每天早上6点，创建四个时间随机的调度任务来完成每日的打卡。

public class ClockThread extends Thread {

  public void run() {

    scheduler = new Scheduler();

    scheduler.schedule("0 6 * * mon,tue,wed,thu,fri", new Thread() {
      @Override
      public void run() {

        if(scheduler1 != null){
          scheduler1.stop();
          scheduler1 = null;
        }
        if(scheduler2 != null){
          scheduler2.stop();
          scheduler2 = null;
        }
        if(scheduler3 != null){
          scheduler3.stop();
          scheduler3 = null;
        }
        if(scheduler4 != null){
          scheduler4.stop();
          scheduler4 = null;
        }
        // 随机在7:00 ~ 7:27之间打卡
        // scheduler1 scheduler.schedule(new Random().nextInt(28)+" 7 * * *",new Thread())
        // 随机在11:30 ~ 11:57之间打卡
        // scheduler2 scheduler.schedule((30 + new Random().nextInt(28))+" 11 * * *",new Thread())
        // 随机在13:00 ~ 13:27之间打卡
        // scheduler3 scheduler.schedule(new Random().nextInt(28)+" 13 * * *",new Thread())
        // 随机在17:30 ~ 17:57之间打卡
        // scheduler4 scheduler.schedule((30 + new Random().nextInt(28))+" 17 * * *",new Thread())


      }
    });

    scheduler.start();

  }

}
