Question

即使在屏幕关闭后我也会进行烤面包（我正在使用Moto e）。当屏幕关闭时，我将手移过传感器区域两次或更多次，立即使用电源按钮打开屏幕并解锁手机我可以看到吐司。我可以看到＆＃34;看到＆＃34;和＆＃34;哟＆＃34;因为我编写了近距离和远距离，我使用了Toast.LENGTH_LONG所以吐司有几秒钟。

现在我想打开屏幕并使用接近传感器打开屏幕锁。

我仍然感到困惑，我有Android问题3708吗？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;
    }

                  window.addFlags(LayoutParams.FLAG_SHOW_WHEN_LOCKED);
                  window.addFlags(LayoutParams.FLAG_TURN_SCREEN_ON);
            }

        }

Answer 1

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);

OR

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();

需要许可<uses-permission android:name="android.permission.WAKE_LOCK" />

OR

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

OR

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();

当你完成它时，不要忘记释放唤醒锁。

您需要申请权限<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或模式解锁

手机屏幕关闭后，请打开屏幕
