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) {
}
}
