android 利用重力感应监听 来电时翻转手机后静音
在CallNotifier.java中 加入如下代码:
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); }
再在相应位置调用如上方法即可以实现此功能。
android 重力感应监听:
public class ShakeListener implements SensorEventListener { public static ShakeListener sensor1; // 速度阈值,当摇晃速度达到这值后产生作用 private static final int SPEED_SHRESHOLD = 400; // 两次检测的时间间隔 private static final int UPTATE_INTERVAL_TIME = 70; // 传感器管理器 private SensorManager sensorManager; // 传感器 private Sensor sensor; // 重力感应易做图 private OnShakeListener onShakeListener; // 上下文 private static Context context; // 手机上一个位置时重力感应坐标 private float lastX; private float lastY; private float lastZ; // 上次检测时间 private long lastUpdateTime;
public static ShakeListener newInstance(Context c) { if (sensor1 == null) { sensor1 = new ShakeListener(); context = c; return sensor1; } else { return sensor1; } } // 开始 public void start() { // 获得传感器管理器 if(sensorManager==null){ sensorManager = (SensorManager) context .getSystemService(Context.SENSOR_SERVICE); } if (sensorManager != null&&sensor==null) { // 获得重力传感器 sensor = sensorManager.getDefaultSensor(Sensor.TYPE_ACCELEROMETER); } if (sensor != null) { sensorManager.registerListener(this, sensor, SensorManager.SENSOR_DELAY_NORMAL); } } // 停止检测 public void stop() { sensorManager.unregisterListener(this); } // 摇晃监听接口 public inte易做图ce OnShakeListener { public void onShake(); } // 设置重力感应易做图 public void setOnShakeListener(OnShakeListener listener) { onShakeListener = listener; } // 重力感应器感应获得变化数据 @Override public void onSensorChanged(SensorEvent event) { long currentUpdateTime = System.currentTimeMillis(); // 两次检测的时间间隔 long timeInterval = currentUpdateTime - lastUpdateTime; // 判断是否达到了检测时间间隔 if (timeInterval < UPTATE_INTERVAL_TIME) { return; } // 现在的时间变成last时间 lastUpdateTime = currentUpdateTime; // 获得x,y,z坐标 float x = event.values[0]; float y = event.values[1]; float z = event.values[2]; // 获得x,y,z的变化值 float deltaX = x - lastX; float deltaY = y - lastY; float deltaZ = z - lastZ; // 将现在的坐标变成last坐标 lastX = x; lastY = y; lastZ = z; double speed = Math.sqrt(deltaX * deltaX + deltaY * deltaY + deltaZ * deltaZ) / timeInterval * 10000; // 达到速度阀值,发出提示 if (speed >= SPEED_SHRESHOLD){ // 手机晃动 onShakeListener.onShake(); } } public void onAccuracyChanged(Sensor sensor, int accuracy) { } }
