即使在电话屏幕关闭后仍然打开屏幕

即使在屏幕关闭后我仍然得到烤面包（我正在使用Moto e）。当屏幕关闭时，我正在移动感应器区域两次或更多时间，然后立即转动在屏幕上使用电源按钮和解锁手机，我可以看到吐司。我可以看到“看到”和“哟”，因为我编码为近和远，我使用Toast.LENGTH_LONG所以敬酒在那里几秒钟。即使在电话屏幕关闭后仍然打开屏幕

现在我想打开屏幕并使用接近传感器打开屏幕锁定。

我仍然迷惑我是否有Android版本3708？非常感谢。

public void onSensorChanged(SensorEvent event) { 
     Log.i(TAG, "onSensorChanged()."); 
     if(event.values[0]==3.0) 
     { 
     Toast.makeText(getApplicationContext(), "see", Toast.LENGTH_LONG).show(); 
     // startService(new Intent(this, TheService.class)); 
     // i want to open screen lock here 
      new ServiceLockTest().data(); 
     } 
     else 
      Toast.makeText(getApplicationContext(), "yo", Toast.LENGTH_LONG).show(); 
     } 

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

     mSensorManager = (SensorManager) getSystemService(SENSOR_SERVICE); 

     manager = (PowerManager) getSystemService(Context.POWER_SERVICE); 

     mWakeLock = manager.newWakeLock(PowerManager.PARTIAL_WAKE_LOCK, TAG); 

     registerReceiver(mReceiver, new IntentFilter(Intent.ACTION_SCREEN_OFF)); 
    } 


    @Override 
    public int onStartCommand(Intent intent, int flags, int startId) { 
     super.onStartCommand(intent, flags, startId); 
     Notification.Builder mBuilder = 
       new Notification.Builder(getApplicationContext()) 
     .setContentTitle("see") 
     .setSmallIcon(R.drawable.ic_lock_idle_alarm) 
     .setContentText("yo"); 
     notification = mBuilder.build(); 

     startForeground(Process.myPid(),notification); 
     registerListener(); 
     mWakeLock.acquire(); 

     return START_STICKY; 
    }

     public class ServiceLockTest extends Activity {

      }

试试这个：

Window window = this.getWindow(); 
window.addFlags(LayoutParams.FLAG_DISMISS_KEYGUARD); 
window.addFlags(LayoutParams.FLAG_SHOW_WHEN_LOCKED); 
window.addFlags(LayoutParams.FLAG_TURN_SCREEN_ON);

PowerManager pm = (PowerManager) getSystemService(Context.POWER_SERVICE); 
WakeLock wakeLock = pm.newWakeLock(PowerManager.FULL_WAKE_LOCK | PowerManager.ACQUIRE_CAUSES_WAKEUP | PowerManager.ON_AFTER_RELEASE, "MyWakeLock"); 
wakeLock.acquire();

它所需的权限<uses-permission android:name="android.permission.WAKE_LOCK" />

WindowManager.LayoutParams params = getWindow().getAttributes(); 
params.flags |= LayoutParams.FLAG_KEEP_SCREEN_ON; 
params.screenBrightness = 1; 
getWindow().setAttributes(params);

KeyguardManager km = (KeyguardManager) context.getSystemService(Context.KEYGUARD_SERVICE); 
final KeyguardManager.KeyguardLock kl = km.newKeyguardLock("MyKeyguardLock"); 
kl.disableKeyguard(); 

PowerManager pm = (PowerManager) context.getSystemService(Context.POWER_SERVICE); 
wakeLock = pm.newWakeLock(PowerManager.FULL_WAKE_LOCK | PowerManager.ACQUIRE_CAUSES_WAKEUP 
     | PowerManager.ON_AFTER_RELEASE, "MyWakeLock"); 
wakeLock.acquire();

不要忘记释放唤醒锁，当你用它做。

您需要申请许可<uses-permission android:name="android.permission.DISABLE_KEYGUARD" />和<uses-permission android:name="android.permission.WAKE_LOCK" />

警告：kl.disableKeyguard()绕过任何PIN码或图案解锁

在那里我把代码？ – 2014-09-05 18:26:36

把它放在方法中，并在你想要唤醒屏幕时调用方法。 – 2014-09-05 18:29:08
