Android uses gravity sensing to listen for phone calls, flip the phone, and then mute

Add the following code to CallNotifier. java:

 

public void GetSensorManager(Context context) {         sm = (SensorManager) context                 .getSystemService(Service.SENSOR_SERVICE);         sensor = sm.getDefaultSensor(Sensor.TYPE_ACCELEROMETER);         mySensorListener = new SensorEventListener() {             @Override             public void onSensorChanged(SensorEvent event) {                 x = event.values[0];                  y = event.values[1];                  z = event.values[2];                  if (x < 1 && x > -1 && y < 1 && y > -1) {                                      if (z > 0) {                         mGoUp = true;                                              } else {                                                  mGoUp = false;                     }                                      } else { //                  if (x > 1 || x < -1 || y > 1 || y < -1 ) {                                                   if ( z > 0 && !mGoUp ) {                             mRinger.stopRing();                             if(mySensorListener != null){                                 sm.unregisterListener(mySensorListener);    //Add by kylin 2013.07.25                                                               }                         }                          if ( z < 0 && mGoUp ) {                             mRinger.stopRing();                             if(mySensorListener != null){                                 sm.unregisterListener(mySensorListener);    //Add by kylin 2013.07.25                              }                         }    //                  }                                        }                              }               @Override             public void onAccuracyChanged(Sensor sensor, int accuracy) {                 // TODO Auto-generated method stub               }         };         sm.registerListener(mySensorListener, sensor,                 SensorManager.SENSOR_DELAY_GAME);              }  public void GetSensorManager(Context context) {  sm = (SensorManager) context    .getSystemService(Service.SENSOR_SERVICE);  sensor = sm.getDefaultSensor(Sensor.TYPE_ACCELEROMETER);  mySensorListener = new SensorEventListener() {   @Override   public void onSensorChanged(SensorEvent event) {    x = event.values[0];    y = event.values[1];    z = event.values[2];    if (x < 1 && x > -1 && y < 1 && y > -1) {         if (z > 0) {      mGoUp = true;           } else {            mGoUp = false;     }         } else {//     if (x > 1 || x < -1 || y > 1 || y < -1 ) {            if ( z > 0 && !mGoUp ) {       mRinger.stopRing();       if(mySensorListener != null){        sm.unregisterListener(mySensorListener);    //Add by kylin 2013.07.25               }      }      if ( z < 0 && mGoUp ) {       mRinger.stopRing();       if(mySensorListener != null){        sm.unregisterListener(mySensorListener);    //Add by kylin 2013.07.25       }      }//     }         }       }   @Override   public void onAccuracyChanged(Sensor sensor, int accuracy) {    // TODO Auto-generated method stub   }  };  sm.registerListener(mySensorListener, sensor,    SensorManager.SENSOR_DELAY_GAME);   }

You can call the above method at the corresponding position to implement this function.

 

 

Android gravity sensor monitoring:

 

Public class ShakeListener implements SensorEventListener {public static ShakeListener sensor1; // speed threshold value. When the shaking speed reaches this value, private static final int SPEED_SHRESHOLD = 400 is generated; // two detection intervals: private static final int UPTATE_INTERVAL_TIME = 70; // Sensor manager private SensorManager sensorManager; // sensor private Sensor sensor; // gravity Sensor listener private OnShakeListener onShakeListener; // Context private static context Context; // gravity sensing coordinate private float lastX; private float lastY; private float lati; // private long lastUpdateTime;
