[Android实例] 仿微信摇一摇功能实现

该篇文章从eoeAndroid搬迁过来的，原文地址：[Android实例] 仿微信摇一摇功能实现

前段时间，由于换了新工作，参与到公司新项目里，很忙，也没时间去弄一些好玩的东西。这些天不算忙，突然想到我在项目里仿照微信做了摇一摇功能，也就吧该功能提取出来，共享给大家。 摇一摇功能其实很简单，主要用到了加速度传感器，因此需要加入权限

<uses-permission android:name="android.permission.VIBRATE"/>

主要代码如下：

1.监听传感器加速变化并进行处理

@Override
public void onSensorChanged(SensorEvent event) {
// TODO Auto-generated method stub
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) {
if ((Math.abs(values[0]) > 17 || Math.abs(values[1]) > 17 || Math
.abs(values[2]) > 17) && !isShake) {
isShake = true;
new Thread() {
public void run() {
try {
runOnUiThread(new Runnable() {
public void run() {
// 摇动手机后，再伴随震动提示~~
vibrator.vibrate(300);
topLineIv.setVisibility(View.VISIBLE);
bottomLineIv.setVisibility(View.VISIBLE);
startAnimation(false);
}
});
Thread.sleep(500);
runOnUiThread(new Runnable() {
public void run() {
// 摇动手机后，再伴随震动提示~~
vibrator.vibrate(300);
}
});
Thread.sleep(500);
runOnUiThread(new Runnable() {

@Override
public void run() {
// TODO Auto-generated method stub
isShake = false;
startAnimation(true);
}
});
} catch (InterruptedException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
};
}.start();
}
}
}

2.动画效果

private void startAnimation(boolean isBack) {
int type = TranslateAnimation.RELATIVE_TO_SELF;
float topFromYValue;
float topToYValue;
float bottomFromYValue;
float bottomToYValue;
if (isBack) {
topFromYValue = -0.5f;
topToYValue = 0;
bottomFromYValue = 0.5f;
bottomToYValue = 0;
} else {
topFromYValue = 0;
topToYValue = -0.5f;
bottomFromYValue = 0;
bottomToYValue = 0.5f;
}
TranslateAnimation topAnimation = new TranslateAnimation(type, 0, type,
0, type, topFromYValue, type, topToYValue);
topAnimation.setDuration(200);
topAnimation.setFillAfter(true);
TranslateAnimation bottomAnimation = new TranslateAnimation(type, 0,
type, 0, type, bottomFromYValue, type, bottomToYValue);
bottomAnimation.setDuration(200);
bottomAnimation.setFillAfter(true);
if (isBack) {
bottomAnimation
.setAnimationListener(new TranslateAnimation.AnimationListener() {

@Override
public void onAnimationStart(Animation animation) {
// TODO Auto-generated method stub

}

@Override
public void onAnimationRepeat(Animation animation) {
// TODO Auto-generated method stub

}

@Override
public void onAnimationEnd(Animation animation) {
// TODO Auto-generated method stub
topLineIv.setVisibility(View.GONE);
bottomLineIv.setVisibility(View.GONE);
}
});
}
bottomLayout.startAnimation(bottomAnimation);
topLayout.startAnimation(topAnimation);
}
