Android活動解鎖屏幕

我試圖添加一個鎖定屏幕解鎖並顯示Activity的Activity。一切正常，除了解鎖屏幕。 Activity開始，但屏幕保持關閉狀態。但我需要屏幕在Activity開始的同時進行。Android活動解鎖屏幕

我用下面的代碼：

public void vibrate() { 
    if ((deltaX > vibrateThreshold) || (deltaY > vibrateThreshold) || (deltaZ > vibrateThreshold)) { 

      //http://www.androidauthority.com/android-7-0-features-673002/ 

      NotificationCompat.Builder mBuilder = 
        new NotificationCompat.Builder(this) 
          .setSmallIcon(R.mipmap.ic_launcher) 
          .setContentTitle("My notification") 
          .setContentText("Hello World!") 
          .setPriority(Notification.PRIORITY_MAX); 

      NotificationManager notificationManager = 
        (NotificationManager) getSystemService(NOTIFICATION_SERVICE); 


      notificationManager.notify(0, mBuilder.build()); 

      Intent alarmIntent = new Intent("android.intent.action.MAIN"); 
      alarmIntent.setClass(this, test.class); 
      alarmIntent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK); 
     alarmIntent.addFlags(WindowManager.LayoutParams.FLAG_SHOW_WHEN_LOCKED 
        | WindowManager.LayoutParams.FLAG_DISMISS_KEYGUARD 
        | WindowManager.LayoutParams.FLAG_KEEP_SCREEN_ON 
        | WindowManager.LayoutParams.FLAG_TURN_SCREEN_ON); 
      this.startActivity(alarmIntent); 

      new CountDownTimer(25000, 1000) { 

       public void onTick(long millisUntilFinished) { 
        //here you can have your logic to set text to edittext 
       } 
      public void onFinish() { 
      } 
      }.start(); 
    } 
}

在我AndroidManifest我有以下代碼：

<uses-permission android:name="android.permission.WAKE_LOCK" /> 
<uses-permission android:name="android.permission.DISABLE_KEYGUARD" />

嘗試使用KeyguardManager

例子：

KeyguardManager.KeyguardLock keyguardLock = keyguardLock = ((KeyguardManager) getApplicationContext().getSystemService(Context.KEYGUARD_SERVICE)).newKeyguardLock("TAG"); 

keyguardLock.disableKeyguard(); // to unlock the device 
keyguardLock.reenableKeyguard(); // to lock the device, only works if your application called .disableKeyguard before

所需的權限：

<uses-permission android:name="android.permission.DISABLE_KEYGUARD" />

要喚醒設備：

// Called from onCreate 
protected void createWakeLocks(){ 
    PowerManager powerManager = (PowerManager) getSystemService(Context.POWER_SERVICE); 
    fullWakeLock = powerManager.newWakeLock((PowerManager.SCREEN_BRIGHT_WAKE_LOCK | PowerManager.FULL_WAKE_LOCK | PowerManager.ACQUIRE_CAUSES_WAKEUP), "Loneworker - FULL WAKE LOCK"); 
    partialWakeLock = powerManager.newWakeLock(PowerManager.PARTIAL_WAKE_LOCK, "Loneworker - PARTIAL WAKE LOCK"); 
} 

// Called implicitly when device is about to sleep or application is backgrounded 
protected void onPause(){ 
    super.onPause(); 
    partialWakeLock.acquire(); 
} 

// Called implicitly when device is about to wake up or foregrounded 
protected void onResume(){ 
    super.onResume(); 
    if(fullWakeLock.isHeld()){ 
     fullWakeLock.release(); 
    } 
    if(partialWakeLock.isHeld()){ 
     partialWakeLock.release(); 
    } 
}

謝謝，我如何讓屏幕繼續？ –

我編輯了我的帖子，並提供了另一個問題的鏈接 – Denny

片斷如何解鎖和鎖定屏幕：

//Get the window from the context  
WindowManager wm = Context.getSystemService(Context.WINDOW_SERVICE); 

//Unlock 
Window window = getWindow(); 
window.addFlags(wm.LayoutParams.FLAG_DISMISS_KEYGUARD); 

//Lock device 
DevicePolicyManager mDPM = (DevicePolicyManager)getSystemService(Context.DEVICE_POLICY_SERVICE);
