Android实现摇一摇

手机摇一摇这功能也是很常见的功能，这里实现的是摇一摇震动和声音都可以产生

创建一个Java类继承与SensorEventListener接口

package com.tenghu.shake;
import android.app.Service;
import android.content.Context;
import android.hardware.Sensor;
import android.hardware.SensorEvent;
import android.hardware.SensorEventListener;
import android.hardware.SensorManager;
import android.media.MediaPlayer;
import android.os.Vibrator;

public class ShakeListener implements SensorEventListener{
	//速度阀值，当摇晃速度达到这值产生作用
	private static final int SPEED_SHRESHOLD=3000;
	//两次检测的时间间隔
	private static final int UPDATE_INTERVAL_TIME=70;
	//传感器管理器
	private SensorManager sensorManager;
	//传感器
	private Sensor sensor;
	//重力感应监听器
	private OnShakeListener onShakeListener;
	//上下文
	private 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;
	//上一次检测时间
	private long lastUpdateTime;
	//创建MediaPlayer对象
	private MediaPlayer player;
	//创建Vibrator对象
	private Vibrator vibrator;
	
	
	public ShakeListener(Context c) {
		//获取上下文对象
		this.context=c;
		start();
	}
	
	//开始
	public void start(){
		//获取传感器对象
		sensorManager=(SensorManager) this.context.getSystemService(Context.SENSOR_SERVICE);
		if(null!=sensorManager){
			//获取重力感应器
			sensor=sensorManager.getDefaultSensor(Sensor.TYPE_ACCELEROMETER);
		}
		//注册
		if(null!=sensor){
			sensorManager.registerListener(this, sensor,SensorManager.SENSOR_DELAY_GAME);
		}
		//获取MediaPlay对象
		player=new MediaPlayer();
		player=MediaPlayer.create(context, R.raw.shake_match);
		//获取震动对象
		vibrator=(Vibrator) this.context.getSystemService(Service.VIBRATOR_SERVICE);
	}
	
	//停止检测
	public void stop(){
		//取消注册
		sensorManager.unregisterListener(this);
	}
	
	//停止播放声音
	public void stopMusic(){
		if(null!=player){
			player.stop();
		}
		//关闭震动
		vibrator.cancel();
	}
	//设置重力感应监听器
	public void setOnShakeListener(OnShakeListener listener){
		onShakeListener=listener;
	}
	//重力感应器获得变化数据
	@Override
	public void onSensorChanged(SensorEvent event) {
		//当前的时间
		long currentUpdateTime=System.currentTimeMillis();
		//两次检测时间间隔
		long timeInterval=currentUpdateTime-lastUpdateTime;
		//判断是否达到检测时间间隔
		if(timeInterval=SPEED_SHRESHOLD){
			onShakeListener.onShake();
			//开始音乐
			player.start();
			//震动
			vibrator.vibrate(new long[]{100,100,100,1000},-1);
		}
	}

	@Override
	public void onAccuracyChanged(Sensor sensor, int accuracy) {
	}
	//摇晃监听接口
	public interface OnShakeListener{
		public void onShake();
	}
}

在Activity中调用

package com.tenghu.shake;

import android.os.Bundle;
import android.os.Handler;
import android.app.Activity;
import android.view.View;
import android.view.Window;
import android.view.animation.Animation;
import android.view.animation.AnimationSet;
import android.view.animation.TranslateAnimation;
import android.widget.Button;
import android.widget.RelativeLayout;
import android.widget.SlidingDrawer;
import android.widget.Toast;

@SuppressWarnings("deprecation")
public class MainActivity extends Activity {
	// 声明相对布局对象
	private RelativeLayout menuTitle, shakeUp, shakeDown;
	// 声明隐式抽屉对象
	private SlidingDrawer slidingDrawer;
	// 隐式操作按钮
	private Button handler;

	ShakeListener shakeListener;
	
	@Override
	protected void onCreate(Bundle savedInstanceState) {
		super.onCreate(savedInstanceState);
		// 取消标题
		requestWindowFeature(Window.FEATURE_NO_TITLE);
		setContentView(R.layout.activity_main);
		// 获取对象
		menuTitle = (RelativeLayout) this.findViewById(R.id.shake_title_bar);
		shakeUp = (RelativeLayout) this.findViewById(R.id.imageShakeUp);
		shakeDown = (RelativeLayout) this.findViewById(R.id.imageShakeDown);

		slidingDrawer = (SlidingDrawer) this.findViewById(R.id.slidingDrawer);
		handler = (Button) this.findViewById(R.id.handler);
		
		// 打开隐式抽屉
		slidingDrawer
				.setOnDrawerOpenListener(new SlidingDrawer.OnDrawerOpenListener() {
					@Override
					public void onDrawerOpened() {
						handler.setBackgroundResource(R.drawable.sliding_back_down);
						// 创建位置转换动画对象
						TranslateAnimation titleUp = new TranslateAnimation(
								Animation.RELATIVE_TO_SELF, 0f,
								Animation.RELATIVE_TO_SELF, 0f,
								Animation.RELATIVE_TO_SELF, 0f,
								Animation.RELATIVE_TO_SELF, -1.0f);
						// 设置次序时间
						titleUp.setDuration(300);
						titleUp.setFillAfter(true);
						// 设置动画
						menuTitle.setAnimation(titleUp);
					}
				});

		// 关闭隐式抽屉
		slidingDrawer
				.setOnDrawerCloseListener(new SlidingDrawer.OnDrawerCloseListener() {

					@Override
					public void onDrawerClosed() {
						handler.setBackgroundResource(R.drawable.sliding_back_up);
						TranslateAnimation titledn = new TranslateAnimation(
								Animation.RELATIVE_TO_SELF, 0f,
								Animation.RELATIVE_TO_SELF, 0f,
								Animation.RELATIVE_TO_SELF, -1.0f,
								Animation.RELATIVE_TO_SELF, 0f);
						titledn.setDuration(200);
						titledn.setFillAfter(false);
						menuTitle.startAnimation(titledn);
					}
				});
		// 创建传感器对象
		shakeListener = new ShakeListener(this);
		shakeListener.setOnShakeListener(new ShakeListener.OnShakeListener() {
			
			@Override
			public void onShake() {
				// 开始动画
				startAnim();
				shakeListener.stop();
				new Handler().postDelayed(new Runnable() {
					@Override
					public void run() {
						Toast.makeText(getApplicationContext(), "震动了",
								Toast.LENGTH_SHORT).show();
						//当手机震动了，则打开抽屉
						slidingDrawer.animateOpen();
						//停止播放声音
						shakeListener.stopMusic();
						shakeListener.start();
					}
				}, 2000);
			}
		});
	}
	@Override
	protected void onDestroy() {
		super.onDestroy();
		if (shakeListener != null) {
			shakeListener.stop();
		}
	}

	/**
	 * 定义摇一摇动画
	 */
	public void startAnim() {

		AnimationSet animup = new AnimationSet(true);
		TranslateAnimation mytranslateanimup0 = new TranslateAnimation(
				Animation.RELATIVE_TO_SELF, 0f, Animation.RELATIVE_TO_SELF, 0f,
				Animation.RELATIVE_TO_SELF, 0f, Animation.RELATIVE_TO_SELF, -1f);
		mytranslateanimup0.setDuration(1000);
		TranslateAnimation mytranslateanimup1 = new TranslateAnimation(
				Animation.RELATIVE_TO_SELF, 0f, Animation.RELATIVE_TO_SELF, 0f,
				Animation.RELATIVE_TO_SELF, 0f, Animation.RELATIVE_TO_SELF, +1f);
		mytranslateanimup1.setDuration(1000);
		mytranslateanimup1.setStartOffset(1000);
		animup.addAnimation(mytranslateanimup0);
		animup.addAnimation(mytranslateanimup1);
		shakeUp.startAnimation(animup);

		AnimationSet animdn = new AnimationSet(true);
		TranslateAnimation mytranslateanimdn0 = new TranslateAnimation(
				Animation.RELATIVE_TO_SELF, 0f, Animation.RELATIVE_TO_SELF, 0f,
				Animation.RELATIVE_TO_SELF, 0f, Animation.RELATIVE_TO_SELF, +1f);
		mytranslateanimdn0.setDuration(1000);
		TranslateAnimation mytranslateanimdn1 = new TranslateAnimation(
				Animation.RELATIVE_TO_SELF, 0f, Animation.RELATIVE_TO_SELF, 0f,
				Animation.RELATIVE_TO_SELF, 0f, Animation.RELATIVE_TO_SELF, -1f);
		mytranslateanimdn1.setDuration(1000);
		mytranslateanimdn1.setStartOffset(1000);
		animdn.addAnimation(mytranslateanimdn0);
		animdn.addAnimation(mytranslateanimdn1);
		shakeDown.startAnimation(animdn);
	}

	/**
	 * 开始动画
	 */
	public void linshi(View v) {
		startAnim();
	}
}

这里的声音文件是放在res目录下的raw目录中的，这个目录需要自己创建

最后就是还要加入手机震动的权限

就完成了这样的功能
