首先需要用到一个摇一摇的工具类
ShakeManager.java
1 package com.wuxianedu.oschina.utils; 2 3 import android.content.Context; 4 import android.hardware.Sensor; 5 import android.hardware.SensorEvent; 6 import android.hardware.SensorEventListener; 7 import android.hardware.SensorManager; 8 9 /** 10 * 震动监听器 11 */ 12 public class ShakeManager implements SensorEventListener { 13 14 private Context mContext; 15 private static final int SPEED_SHRESHOLD = 4500;//这个值越大需要越大的力气来摇晃手机 16 private static final int UPTATE_INTERVAL_TIME = 50; 17 private SensorManager sensorManager; 18 private Sensor sensor; 19 private ShakeListener shakeListener; 20 private float lastX; 21 private float lastY; 22 private float lastZ; 23 private long lastUpdateTime; 24 25 public ShakeManager(Context c) { 26 mContext = c; 27 start(); 28 } 29 30 /** 31 * 启动 32 */ 33 public void start() { 34 sensorManager = (SensorManager) mContext.getSystemService(Context.SENSOR_SERVICE); 35 if (sensorManager != null) { 36 sensor = sensorManager.getDefaultSensor(Sensor.TYPE_ACCELEROMETER); 37 } 38 if (sensor != null) { 39 sensorManager.registerListener(this, sensor, SensorManager.SENSOR_DELAY_GAME); 40 } 41 } 42 43 /** 44 * 停止 45 */ 46 public void stop() { 47 sensorManager.unregisterListener(this); 48 } 49 50 public void onSensorChanged(SensorEvent event) { 51 long currentUpdateTime = System.currentTimeMillis(); 52 long timeInterval = currentUpdateTime - lastUpdateTime; 53 if (timeInterval < UPTATE_INTERVAL_TIME) 54 return; 55 lastUpdateTime = currentUpdateTime; 56 57 float x = event.values[0]; 58 float y = event.values[1]; 59 float z = event.values[2]; 60 61 float deltaX = x - lastX; 62 float deltaY = y - lastY; 63 float deltaZ = z - lastZ; 64 65 lastX = x; 66 lastY = y; 67 lastZ = z; 68 69 double speed = Math.sqrt(deltaX * deltaX + deltaY * deltaY + deltaZ 70 * deltaZ) 71 / timeInterval * 10000; 72 if (speed >= SPEED_SHRESHOLD) { 73 shakeListener.onShake(); 74 } 75 } 76 77 public void onAccuracyChanged(Sensor sensor, int accuracy) {} 78 79 public void setShakeListener(ShakeListener shakeListener) { 80 this.shakeListener = shakeListener; 81 } 82 83 public interface ShakeListener { 84 void onShake(); 85 } 86 87 }
接下来我们在MainActivity.java中来使用
1 private ShakeManager shake; 2 3 shake.setShakeListener(new ShakeManager.ShakeListener() { 4 @Override 5 public void onShake() { 6 QiStart(); 7 shake.stop(); 8 canrads.setVisibility(View.GONE); 9 soundPool.play(map.get(1),0.3f,0.3f,1,0,0); 10 } 11 }); 12 13 14 15 /** 16 * 开始动画 17 */ 18 private void QiStart() { 19 TranslateAnimation up = new TranslateAnimation(Animation.RELATIVE_TO_SELF,0f,Animation.RELATIVE_TO_SELF,0f 20 ,Animation.RELATIVE_TO_SELF,0f,Animation.RELATIVE_TO_SELF,-0.3f); 21 up.setDuration(600L); 22 up.setRepeatCount(1); 23 up.setRepeatMode(Animation.REVERSE); 24 imageshang.startAnimation(up); 25 26 TranslateAnimation down = new TranslateAnimation(Animation.RELATIVE_TO_SELF,0f,Animation.RELATIVE_TO_SELF,0f 27 ,Animation.RELATIVE_TO_SELF,0f,Animation.RELATIVE_TO_SELF,0.3f); 28 down.setDuration(600L); 29 down.setRepeatCount(1); 30 down.setRepeatMode(Animation.REVERSE); 31 imagexia.startAnimation(down); 32 33 down.setAnimationListener(new Animation.AnimationListener() { 34 @Override 35 public void onAnimationStart(Animation animation) { 36 37 } 38 @Override 39 public void onAnimationEnd(Animation animation) { 40 xian2.setVisibility(View.VISIBLE); 41 new RequestClient(getContext(),requestConfig){ 42 43 @Override 44 protected void loadSuccess(String result) { 45 try { 46 result = new String(result.getBytes("ISO-8859-1"),"UTF-8"); 47 } catch (UnsupportedEncodingException e) { 48 e.printStackTrace(); 49 } 50 shakeb = JSONParseUtil.parseObject(result,Shakeb.class); 51 assert shakeb != null; 52 String title = shakeb.getOwner()!=null ? shakeb.getOwner().getName():""; 53 tv_neirong.setText(title); 54 tv_biaoti.setText(shakeb.getDescription()); 55 tv_chakan.setText(String.valueOf(shakeb.getForks_count())); 56 tv_xingxing.setText(String.valueOf(shakeb.getStars_count())); 57 tv_disange.setText(String.valueOf(shakeb.getWatches_count())); 58 //获取图片地址 59 String imageUrl = shakeb.getOwner().getNew_portrait(); 60 ImageLoader imageLoader = ImageLoaderFactory.getImageLoader(); 61 //加载图片 62 imageLoader.loadImage(imageUrl,roundImageView); 63 //隐藏正在加载 64 xian2.setVisibility(View.GONE); 65 //播放声音 66 soundPool.play(map.get(0),0.3f,0.3f,1,0,0); 67 //显示推举项目 68 canrads.setVisibility(View.VISIBLE); 69 //摇一摇监听开始 70 shake.start(); 71 } 72 73 @Override 74 protected void loadFail() { 75 76 } 77 }.get(RequestAPI.SHAKE); 78 } 79 80 @Override 81 public void onAnimationRepeat(Animation animation) { 82 83 } 84 }); 85 86 }
/** * 判断Fragment是否可见 * @param hidden */ @Override public void onHiddenChanged(boolean hidden) { super.onHiddenChanged(hidden); if(hidden){ shake.stop(); }else{ shake.start(); } } true为不可见
