android 计步器 计算当前的行走步数

 看一下效果图：

import com.leng.jbq.TodayStepService;

public class MainActivity extends AppCompatActivity {
    private static String TAG = "MainActivity";

    private static final int REFRESH_STEP_WHAT = 0;

    //循环取当前时刻的步数中间的间隔时间
    private long TIME_INTERVAL_REFRESH = 500;

    private Handler mDelayHandler = new Handler(new TodayStepCounterCall());
    private int mStepSum;

    private ISportStepInterface iSportStepInterface;

    private TextView mStepArrayTextView;

    @Override
    protected void onCreate(Bundle savedInstanceState) {

        //初始化计步模块
        TodayStepManager.init(getApplication());

//        mStepArrayTextView = (TextView)findViewById(R.id.stepArrayTextView);

        //开启计步Service，同时绑定Activity进行aidl通信
        Intent intent = new Intent(this, TodayStepService.class);
        startService(intent);
        bindService(intent, new ServiceConnection() {
            @Override
            public void onServiceConnected(ComponentName name, IBinder service) {

                try {

                    updateStepCount();
                } catch (RemoteException e) {

            }

            @Override
            public void onServiceDisconnected(ComponentName name) {

            }
        }, Context.BIND_AUTO_CREATE);

    }

    class TodayStepCounterCall implements Handler.Callback{

        @Override
        public boolean handleMessage(Message msg) {
            switch (msg.what) {
                case REFRESH_STEP_WHAT: {
                    //每隔500毫秒获取一次计步数据刷新UI
                    if (null != iSportStepInterface) {
                        int step = 0;
                        try {

                        }
                        if (mStepSum != step) {
                            mStepSum = step;
                            updateStepCount();

                    }
                    mDelayHandler.sendEmptyMessageDelayed(REFRESH_STEP_WHAT, TIME_INTERVAL_REFRESH);

                    break;
                }
            }
            return false;
        }
    }

    private void updateStepCount() {

        stepTextView.setText(mStepSum + "步");

    }

       
}

布局文件：

xml version="1.0" encoding="utf-8"?>
xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"

        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" />

  

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 {
        applicationId "com.leng.jibuqi"
