Android计步模块(类似微信运动，支付宝计步，今日步数)

接入方法

1.先下载计步demo TodayStepCounter

2.demo项目结构如下图：

由图可见todaystepcounterlib是计步模块封装好的Module，它对外提供的接口就是ISportStepInterface.aidl

3.如何接入：

查看对外接口ISportStepInterface.aidl如下代码：

// ISportStepInterface.aidl

package com.today.step.lib;

interface ISportStepInterface {

/**

* 获取当前时间运动步数

*/

int getCurrentTimeSportStep();

/**

* 获取当天步数列表，json格式

*/

String getTodaySportStepArray();

}

查看使用代码MainActivity.java，里面关键代码有注释非常简单

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) {

super.onCreate(savedInstanceState);

setContentView(R.layout.activity_main);

//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) {

//Activity和Service通过aidl进行通信

iSportStepInterface = ISportStepInterface.Stub.asInterface(service);

try {

mStepSum = iSportStepInterface.getCurrentTimeSportStep();

updateStepCount();

} catch (RemoteException e) {

e.printStackTrace();

}

mDelayHandler.sendEmptyMessageDelayed(REFRESH_STEP_WHAT, TIME_INTERVAL_REFRESH);

}

@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 {

step = iSportStepInterface.getCurrentTimeSportStep();

} catch (RemoteException e) {

e.printStackTrace();

}

if (mStepSum != step) {

mStepSum = step;

updateStepCount();

}

}

mDelayHandler.sendEmptyMessageDelayed(REFRESH_STEP_WHAT, TIME_INTERVAL_REFRESH);

break;

}

}

return false;

}

}

private void updateStepCount() {

Log.e(TAG,"updateStepCount : " + mStepSum);

TextView stepTextView = (TextView)findViewById(R.id.stepTextView);

stepTextView.setText(mStepSum + "步");

}

public void onClick(View view){

switch (view.getId()){

case R.id.stepArrayButton:{

//显示当天计步数据详细，步数对应当前时间

if(null != iSportStepInterface){

try {

String stepArray = iSportStepInterface.getTodaySportStepArray();

mStepArrayTextView.setText(stepArray);

} catch (RemoteException e) {

e.printStackTrace();

}

}

break;

}

default:break;

}

}

}
