Question

我想开发一个Android应用程序，我想用接近传感器或ACCELEROMETER传感器接听电话。在来电的情况下，当我获得传感器的某个值时，将自动接收呼叫。例如，当我从左到右移动接近传感器前面的手时，将从右到左接收呼叫，然后呼叫将被拒绝。对于Accelerometer，当我用耳朵触摸我的手机时，传感器将收到一定的x，y，z值，然后接收电话。我尝试了一些东西但是，当手机接到来自号码的电话时，我无法读取传感器值。当手机接到电话时，是否可以在BroadCastReceiver内获取传感器值或读取传感器？我在Play商店测试过这样一个名为“Wave Control Pro”的应用程序 https://play.google.com/store/apps/details?id=com.MarksThinkTank.WaveControlPro&feature=search_result

使用就像在这里我得到传感器水平和垂直

public class SensorActivity extends Activity implements SensorEventListener{
    private static final String TAG="SensorActivity";

    private Context context=null;
    private float mLastX, mLastY, mLastZ;
    private boolean mInitialized;
    private SensorManager mSensorManager;
    private Sensor mAccelerometer;
    private final float NOISE = (float) 5.0;

    ArrayList<String> arraylist=null;

    private SharedPreferences seedPrefs = null;
    private String prefname = "shakingvideo";

    VideoBean vbean= new VideoBean();

      @Override
      public void onCreate(Bundle savedInstanceState) {
           super.onCreate(savedInstanceState);
           setContentView(R.layout.video);
           context=this;

           mInitialized = false;
           mSensorManager = (SensorManager) getSystemService(Context.SENSOR_SERVICE);
           mAccelerometer = mSensorManager.getDefaultSensor(Sensor.TYPE_ACCELEROMETER);
           mSensorManager.registerListener(this, mAccelerometer , SensorManager.SENSOR_DELAY_NORMAL);

            arraylist= new ArrayList<String>();

      }

      @Override
    protected void onResume() {
        super.onResume();
        mSensorManager.registerListener(this, mAccelerometer, SensorManager.SENSOR_DELAY_NORMAL);
    }

      @Override
    protected void onPause() {
        super.onPause();
        mSensorManager.unregisterListener(this);
    }


    public void onAccuracyChanged(Sensor arg0, int arg1) {
        // TODO Auto-generated method stub

    }

    public void onSensorChanged(SensorEvent event) {

        float x = event.values[0];
        float y = event.values[1];
        float z = event.values[2];


        if (!mInitialized) {
            mLastX = x;
            mLastY = y;
            mLastZ = z;
            mInitialized = true;
        } else {
            float deltaX = Math.abs(mLastX - x);
            float deltaY = Math.abs(mLastY - y);
            float deltaZ = Math.abs(mLastZ - z);
            if (deltaX < NOISE) deltaX = (float)0.0;
            if (deltaY < NOISE) deltaY = (float)0.0;
            if (deltaZ < NOISE) deltaZ = (float)0.0;
            mLastX = x;
            mLastY = y;
            mLastZ = z;
            if (deltaX > deltaY) {


                // horizontal shaking    receive here your call

            } else if (deltaY > deltaX) {

                //Reject here your call

            } else {
                // no shaking
            }
        }
    }
}

如何使用我的Android应用程序使用传感器接收电话？
