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

@Override
protected void onResume() {
    super.onResume();
    mShakeUtils.onResume();
}
@Override
protected 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();
    }
});
