我知道这个问题已经运行了一段时间,并且不建议想要实现这一点,但即使手机处于待机模式,我也需要我的服务传感器才能工作。
到目前为止,我所拥有的是:
public class SensorOrientation extends Service implements SensorEventListener{
private SensorManager mSensorManager = null;
private Sensor orientation;
private int dureeDetection;
private int angle;
private int angleOrientation;
public static final int SCREEN_OFF_RECEIVER_DELAY = 500;
public static final String TAG = SensorOrientation.class.getName();
private WakeLock mWakeLock = null;
private static final String LOG_TAG = "SensorsOrientation";
float x, y, z;
protected BroadcastReceiver mreceiver;
public int onStartCommand(final Intent intent, final int flags,
final int startId) {
startForeground(1, new Notification());
registerListener();
mWakeLock.acquire();
return START_STICKY;
}
private void registerListener() {
mSensorManager.registerListener(this,
mSensorManager.getDefaultSensor(Sensor.TYPE_ORIENTATION),
SensorManager.SENSOR_DELAY_UI);
}
private void unregisterListener() {
mSensorManager.unregisterListener(this);
}
public BroadcastReceiver mReceiver = new BroadcastReceiver() {
@Override
public void onReceive(Context context, Intent intent) {
Log.i(TAG, "onReceive("+intent+")");
if (!intent.getAction().equals(Intent.ACTION_SCREEN_OFF)) {
return;
}
Runnable runnable = new Runnable() {
public void run() {
Log.i(TAG, "Runnable executing.");
unregisterListener();
registerListener();
}
};
new Handler().postDelayed(runnable, SCREEN_OFF_RECEIVER_DELAY);
}
};
public void onSensorChanged(SensorEvent event) {
// update only when your are in the right case:
Log.i(TAG, "onSensorChanged().");
if (event.sensor.getType() == Sensor.TYPE_ORIENTATION) {
// the azimuts
x = event.values[0];
// the pitch
y = event.values[1];
// the roll
z = event.values[2];
angleOrientation = -1 * ((int)y);
if ((angle == 90 && angleOrientation <= 0) ||
(angle == 60 && angleOrientation <= 30) ||
(angle == 40 && angleOrientation <= 50) ||
(angle == 30 && angleOrientation <= 60 )) {
Toast.makeText(SensorOrientation.this,
"perte de verticalité",
Toast.LENGTH_SHORT).show();
}
//Log.d(LOG_TAG, "Sensor's values (" + ((int) x) + "," + ((int) y) + "," + ((int) z) + ")");
}
}
public void onAccuracyChanged(Sensor sensor, int accuracy) {
// TODO Auto-generated method stub
}
@Override
public IBinder onBind(Intent intent) {
// TODO Auto-generated method stub
return null;
}
@Override
public void onCreate() {
super.onCreate();
mSensorManager = (SensorManager) getSystemService(SENSOR_SERVICE);
PowerManager manager =
(PowerManager) getSystemService(Context.POWER_SERVICE);
mWakeLock = manager.newWakeLock(PowerManager.PARTIAL_WAKE_LOCK, TAG);
registerReceiver(mReceiver, new IntentFilter(Intent.ACTION_SCREEN_OFF));
DBAdapter db = new DBAdapter(getApplicationContext());
Cursor options = db.selectVerticalite();
dureeDetection = options.getInt(options.getColumnIndex("duree_detection_verticalite"));
angle = options.getInt(options.getColumnIndex("angle_detection"));
options.close();
}
@Override
public void onDestroy() {
unregisterReceiver(mReceiver);
unregisterListener();
mWakeLock.release();
stopForeground(true);
}
}
但这不起作用,虽然这取决于手机,有什么我做得不对吗?或者根本不做?
编辑1:它适用于SCREEN_DIM_WAKE_LOCK,这是一个非常糟糕的解决方法...
