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;
}
}
}
