Android的传感器监听器并没有得到未注册或传感器仍然检索值 [英] Android sensor listener does not get unregistered or sensor still retrieves values

问题描述

我有一些问题SensorManager.unregisterListener。它们与<类似href=\"http://stackoverflow.com/questions/16504474/android-thread-cannot-unregister-sensoreventlistener\">Android,螺纹，无法注销SensorEventListener 和<一个href=\"https://stackoverflow.com/questions/6919577/sensoreventlistener-doesnt-get-unregistered-with-unregisterlistener-method\">SensorEventListener没有得到取消注册unregisterListener（）方法。但我找不到我的答案！我也跟着的SensorManager例如文档的http://developer.android.com/reference/android/hardware/SensorManager.html#SENSOR_DELAY_UI.

I have some problems with SensorManager.unregisterListener. They are similar with Android, Thread, Cannot unregister SensorEventListener and SensorEventListener doesn't get unregistered with unregisterListener() method. But I could not find my answer! I also followed SensorManager documentation example http://developer.android.com/reference/android/hardware/SensorManager.html#SENSOR_DELAY_UI.

的问题是，在活动结束后我注销听者但传感器持续发​​送值，直到应用程序被完全摧毁。

The problem is that after the Activity is finished I unregister the listener but the sensor keeps sending values until the application is completely destroyed.

这是我的code：

我SensorController实现SensorEventListener

my SensorController implements SensorEventListener

public class SensorController implements SensorEventListener{

构造：

public SensorController(Context context){
    sensorManager = (SensorManager)context.getSystemService(Context.SENSOR_SERVICE);
}

当活动的onResume回调叫做

我SensorController onResume方法被调用：

my SensorController onResume method is called when Activity's onResume callback is called:

public void onResume(){
    mAccelerometerSensor = sensorManager.getDefaultSensor(Sensor.TYPE_ACCELEROMETER);
    boolean ret1 = sensorManager.registerListener(this, mAccelerometerSensor, SensorManager.SENSOR_DELAY_UI);
    mMagneticSensor = sensorManager.getDefaultSensor(Sensor.TYPE_MAGNETIC_FIELD);
    boolean ret2 = sensorManager.registerListener(this, mMagneticSensor, SensorManager.SENSOR_DELAY_UI);

}

当活动的回调的onPause被称为

我SensorController的onPause方法被称为：

my SensorController onPause method is called when Activity's onPause callback is called:

public void onPause(){
    sensorManager.unregisterListener(this);
}

和在SensorChanged我把日志监视传感器事件：

And in on SensorChanged I put a log to monitor the sensor events:

@Override
public void onSensorChanged(SensorEvent event) {
    this.computeRotationAngles(event);
    Log.i("SensorController", "onSensorChanged");
}

所以......活动的onPause方法后，onSensorChanged（SensorEvent事件）还是检索传感器事件。为什么？？我注销它SensorController.onPause（）函数。这些传感器获取良好的价值观，但我不能阻止他们发送。我在做什么错了？

So... after the Activity onPause method, the onSensorChanged(SensorEvent event) still retrieves sensor events. Why?? I unregister it in SensorController.onPause() function. The sensors retrieve good values but I cannot stop them sending. What am I doing wrong?

非常感谢你提前！我会为每一位小技巧感谢：）

Thank you very much in advance! I will be grateful for every small tip :)

推荐答案

尝试卸载应用程序，并重新安装。它适用于我的。

try to uninstall the application and reinstall. it works on mine.
