android 计步器计算当前的行走步数

看一下效果图：

    }

    class TodayStepCounterCall implements Handler.Callback{

        @Override

                    //每隔500毫秒获取一次计步数据刷新UI

布局文件：

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    tools:context="com.leng.jibuqi.MainActivity">

    <TextView
        android:id="@+id/stepTextView"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_centerHorizontal="true"
        android:layout_marginTop="80dp"
        android:text="Hello World!"
        android:textSize="20sp" />

  

</RelativeLayout>

在app的build.gradle下引用jbq-debug.aar的aar包

完整代码：

apply plugin: 'com.android.application'

android {
    compileSdkVersion 26
    buildToolsVersion "26.0.2"
    defaultConfig {
