超精准的Android手机计步器开发

亲测在小米.魅族.华为上可用,该app采用后台service计歩服务，所以只要app不被手机杀死在后台也是可以正常计歩的。上图：

1.需要在AndroidManifest.xml中添加权限

<!--计歩需要的权限-->
 <uses-permission android:name="android.permission.VIBRATE" />
 <uses-permission android:name="android.permission.WRITE_SETTINGS" />
 <uses-feature android:name="android.hardware.sensor.accelerometer" />
 <uses-permission android:name="android.permission.RECEIVE_BOOT_COMPLETED" />
 <uses-permission android:name="android.permission.MOUNT_UNMOUNT_FILESYSTEMS" />
 <uses-feature
 android:name="android.hardware.sensor.stepcounter"
 android:required="true" />
 <uses-feature
 android:name="android.hardware.sensor.stepdetector"
 android:required="true" />

2.检测手机是否支持计歩

 
 @TargetApi(Build.VERSION_CODES.KITKAT)
 public static boolean isSupportStepCountSensor(Context context) {
 // 获取传感器管理器的实例
 SensorManager sensorManager = (SensorManager) context
  .getSystemService(context.SENSOR_SERVICE);
 Sensor countSensor = sensorManager.getDefaultSensor(Sensor.TYPE_STEP_COUNTER);
 Sensor detectorSensor = sensorManager.getDefaultSensor(Sensor.TYPE_STEP_DETECTOR);
 return countSensor != null || detectorSensor != null;
 }

3.功能使用

 private boolean isBind = false;
    private Messenger mGetReplyMessenger = new Messenger(new Handler(this));
    private Messenger messenger;
   
    private void setupService() {
        Intent intent = new Intent(this, StepService.class);
        isBind = bindService(intent, conn, Context.BIND_AUTO_CREATE);
        startService(intent);
    }
    
    @Override

    public boolean handleMessage(Message msg) {
        switch (msg.what) {
            case Constant.MSG_FROM_SERVER:
                cc.setCurrentCount(10000, msg.getData().getInt("step"));
                break;
        }
        return false;
    }
    
    ServiceConnection conn = new ServiceConnection() {
        
        @Override
        public void onServiceConnected(ComponentName name, IBinder service) {
            try {
                messenger = new Messenger(service);
                Message msg = Message.obtain(null, Constant.MSG_FROM_CLIENT);
                msg.replyTo = mGetReplyMessenger;
                messenger.send(msg);
            } catch (RemoteException e) {
                e.printStackTrace();
            }
        }
      
        @Override
        public void onServiceDisconnected(ComponentName name) {
        }
    };
