Android的加速度设置：我可以当按钮，它pressed它只能运行。 [英] Android Accelerometer setup: can I get it to run only when button it pressed.

问题描述

我在我的应用程序中使用加速度计，我想知道如果我能做到的方式，加速计仅针对激活后用户一定的时间已经pressed启动按钮。它应该停止时，用户preSS停止按钮。它将基本上工作作为计步器这是一个更大的应用的一部分。这是用来实现加速度计code： -

I am using an Accelerometer in my application and I am wondering if I can make it the way that accelerometer is only activates for a certain amount of time after the user has pressed a start button. It should stops when user press the stop button. It will essentially work as a pedometer which is part of a bigger application. This is the code used to implement the accelerometer:-

SensorManager sensorManager = (SensorManager)getSystemService(Context.SENSOR_SERVICE);
    int sensorType = Sensor.TYPE_ACCELEROMETER;
    sensorManager.registerListener(sensorListener, sensorManager.getDefaultSensor(sensorType),SensorManager.SENSOR_DELAY_NORMAL);

我有code计数的步骤是： -

I have the code counting the steps which is:-

final SensorEventListener sensorListener = new SensorEventListener()
{

    public void onSensorChanged(SensorEvent event)
    {
            if(event.values[2]<3)
            {
                counter ++;
            }
            else if(event.values[2]>5)
            {
                counter --;
                counter ++;

            }
            sensorData.setText("Steps = "+ counter);

      }

      public void onAccuracyChanged(Sensor sensor, int accuracy){}
      };

我只是想知道，既然我指望在onSensorChanged方法的步骤我怎么限制这只是一个按钮preSS状态？有没有可能在添加计数器开始计数了多久我前面提到？

I'm just wondering that since I'm counting the steps in the onSensorChanged method how do I limit this to only a button press state? Would it be possible to add a timer in to count how long has passed between the two button presses I mentioned earlier?

推荐答案

是的，当然。

prepare经理：

Prepare manager:

mSensorManager = (SensorManager) getSystemService(SENSOR_SERVICE);
mAccelerometer = mSensorManager.getDefaultSensor(Sensor.TYPE_ACCELEROMETER);

启动加速度：

mSensorManager.registerListener(this, mAccelerometer, 
     SensorManager.SENSOR_DELAY_NORMAL);

停止：

mSensorManager.unregisterListener(this);

不要的onPause（）方法。忘记注销监听器

Don't forget unregister listener in onPause() method.
