android实现摇一摇事件监听

首先一个工具类：

package www.basketi.cn.basketball.androidtojs;import android.content.Context;import android.hardware.Sensor;import android.hardware.SensorEvent;import android.hardware.SensorEventListener;import android.hardware.SensorManager;/** * 摇一摇工具类 * 使用说明： * private ShakeUtils mShakeUtils = null; * 1、在需要使用摇一摇功能的Activity实例化该工具类并设置摇一摇监听： * mShakeUtils = new ShakeUtils( this ); * mShakeUtils.setOnShakeListener(new OnShakeListener{ *      public void onShake(){ *          // 此处为摇一摇触发后的操作 *      } * }); * * 2、分别在Activity的onResume和onPause方法中调用该工具类的onResume和onPause方法： * mShakeUtils.onResume(); * mShakeUtils.onPause(); * */public class ShakeUtils implements SensorEventListener {    public ShakeUtils(Context context){        mSensorManager = (SensorManager) context.getSystemService(Context.SENSOR_SERVICE);    }    public void setOnShakeListener( OnShakeListener onShakeListener ){        mOnShakeListener = onShakeListener;    }    public void onResume(){        mSensorManager.registerListener(this,                mSensorManager.getDefaultSensor(Sensor.TYPE_ACCELEROMETER),                SensorManager.SENSOR_DELAY_NORMAL);    }    public void onPause(){        mSensorManager.unregisterListener(this);    }    @Override    public void onAccuracyChanged(Sensor sensor, int accuracy) {    }    @Override    public void onSensorChanged(SensorEvent event) {        int sensorType = event.sensor.getType();        //values[0]:X轴，values[1]：Y轴，values[2]：Z轴        float[] values = event.values;        if (sensorType == Sensor.TYPE_ACCELEROMETER){            //这里可以调节摇一摇的灵敏度            if ((Math.abs(values[0]) > SENSOR_VALUE || Math.abs(values[1]) > SENSOR_VALUE || Math.abs(values[2]) > SENSOR_VALUE)){                System.out.println("sensor value == " + " " + values[ 0 ] + " " + values[ 1 ] + " " +  values[ 2 ] );                if( null != mOnShakeListener ){                    mOnShakeListener.onShake( );                }            }        }    }    public interface OnShakeListener{        public void onShake();    }    private SensorManager mSensorManager = null;    private OnShakeListener mOnShakeListener = null;    private static final int SENSOR_VALUE = 14;}

然后在类中注册和销毁

@Overrideprotected void onResume() {    super.onResume();    mShakeUtils.onResume();}@Overrideprotected void onPause() {    super.onPause();    mShakeUtils.onPause( );}

然后在主类中创建对象

mShakeUtils = new ShakeUtils( this );mShakeUtils.setOnShakeListener(new ShakeUtils.OnShakeListener() {    @Override    public void onShake() {        Toast.makeText(MainActivity.this,"摇一摇",Toast.LENGTH_SHORT).show();    }});
