如何实现Android传感器数据获取

这篇文章主要讲解了"如何实现Android传感器数据获取"，文中的讲解内容简单清晰，易于学习与理解，下面请大家跟着小编的思路慢慢深入，一起来研究和学习"如何实现Android传感器数据获取"吧！

我们先自己定义一个传感器的工具类（因为我这边只是获取了部分的传感器，需要获取额外的传感器自己配置一下就行了，工具类通过重载提供了不同的构造方法）：

public class SensorUtils implements SensorEventListener {     private SensorManager manager;     /**     * @param context 多个传感器     * @param sensorList     */    public void RegisterSensor(Context context, List sensorList){        manager = (SensorManager) context.getSystemService(SENSOR_SERVICE);        for(Sensor sensors : sensorList){            manager.registerListener(this,sensors,SensorManager.SENSOR_DELAY_NORMAL);        }    }     /**     * @param context 单个传感器     * @param sensor     */    public void RegisterSensor(Context context, Sensor sensor){        manager = (SensorManager) context.getSystemService(SENSOR_SERVICE);        manager.registerListener(this,sensor,SensorManager.SENSOR_DELAY_NORMAL);    }     @Override    public void onSensorChanged(SensorEvent event) {        switch (event.sensor.getType()){            case Sensor.TYPE_ACCELEROMETER:                //给加速度传感器设置回调监听                sensorCallBack.acceleratedCallBack(event);                break;            case Sensor.TYPE_GYROSCOPE:                //给陀螺仪传感器设置回调监听                sensorCallBack.gyroscopeCallBack(event);                break;            case Sensor.TYPE_MAGNETIC_FIELD:                //给磁场传感器设置回调监听                sensorCallBack.magneticFieldCallBack(event);                break;            case Sensor.TYPE_PRESSURE:                //给气压计传感器设置回调监听                sensorCallBack.pressureCallBack(event);                break;        }     }     @Override    public void onAccuracyChanged(Sensor sensor, int accuracy) {     }     //使用完之后记得取消注册    public void UnRegisterSensor(){        if (manager != null){            manager.unregisterListener(this);        }    }     public interface SensorCallBack{        void acceleratedCallBack(SensorEvent event);         void gyroscopeCallBack(SensorEvent event);         void magneticFieldCallBack(SensorEvent event);         void pressureCallBack(SensorEvent event);    }    private SensorCallBack sensorCallBack;     public SensorUtils(SensorCallBack sensorCallBack){        this.sensorCallBack = sensorCallBack;    } }

然后我们在activity中去使用工具类：

//初始化sensorUtils = new SensorUtils(this);sensorUtils.RegisterSensor(this, sensorList);

activity中别忘了实现SensorUtil中的回调监听

public class SensorActivity extends BaseActivity implements SensorUtils.SensorCallBack{   //do something}

然后在自己设置的回调监听中去实现自己想要的功能

@Override    public void acceleratedCallBack(SensorEvent event) {        //可以做自己想要的操作        if (event != null) {            float[] values = event.values;            float x1 = values[0];            float y1 = values[1];            float z1 = values[2];            StringBuffer stringBuffer = new StringBuffer();            stringBuffer.append(getString(R.string.accelerometer_number)).append("\n");            stringBuffer.append(getString(R.string.x1)).append(x1).append("\n");            stringBuffer.append(getString(R.string.y1)).append(y1).append("\n");            stringBuffer.append(getString(R.string.z1)).append(z1);            if (!viewDateBinding.scrollView.isMove()) {                handler.post(() -> viewDateBinding.tvAccelerated.setText(stringBuffer.toString()));            }            if (flagAccelerated) {                DataBassManager.getInstance(SensorActivity.this).insertSensor(new TableBean(null,stringBuffer.toString(),null,null,null));            }            flagAccelerated = false;        }    }     @Override    public void gyroscopeCallBack(SensorEvent event) {        //可以做自己想要的操作        if (event != null) {            float x2 = event.values[0];            float y2 = event.values[1];            float z2 = event.values[2];            StringBuffer stringBuffer = new StringBuffer();            stringBuffer.append(getString(R.string.gyroscope_number)).append("\n");            stringBuffer.append(getString(R.string.x2)).append(x2).append("\n");            stringBuffer.append(getString(R.string.y2)).append(y2).append("\n");            stringBuffer.append(getString(R.string.z2)).append(z2);            if (!viewDateBinding.scrollView.isMove()) {                handler.post(() -> viewDateBinding.tvGyroscope.setText(stringBuffer.toString()));            }            if (flagGyroscope) {                DataBassManager.getInstance(SensorActivity.this).insertSensor(new TableBean(null,null,stringBuffer.toString(),null,null));            }            flagGyroscope = false;        }    }     @SuppressLint("DefaultLocale")    @Override    public void magneticFieldCallBack(SensorEvent event) {        //可以做自己想要的操作        if (event != null) {            float x3 = event.values[0];            float y3 = event.values[1];            float z3 = event.values[2];            StringBuffer stringBuffer = new StringBuffer();            stringBuffer.append(getString(R.string.magnetic_field_number)).append("\n");            stringBuffer.append(getString(R.string.x3)).append(String.format("%.2f", x3)).append("\n");            stringBuffer.append(getString(R.string.y3)).append(String.format("%.2f", y3)).append("\n");            stringBuffer.append(getString(R.string.z3)).append(String.format("%.2f", z3));            if (!viewDateBinding.scrollView.isMove()) {                handler.post(() -> viewDateBinding.tvMagneticField.setText(stringBuffer.toString()));            }            if (flagMagneticField) {                DataBassManager.getInstance(SensorActivity.this).insertSensor(new TableBean(null,null,null,stringBuffer.toString(),null));            }            flagMagneticField = false;        }    }     @Override    public void pressureCallBack(SensorEvent event) {        //可以做自己想要的操作        if (event != null) {            float x4 = event.values[0];            String str4 = getString(R.string.pressure_number) + x4;            if (!viewDateBinding.scrollView.isMove()) {                handler.post(() -> viewDateBinding.tvPressure.setText(str4));            }            if (flagPressure) {                DataBassManager.getInstance(SensorActivity.this).insertSensor(new TableBean(null,null,null,null,str4));            }            flagPressure = false;        }    }

我这边是将数据通过按钮的点击事件存储进了数据库，注意传感器的回调是实时的，所以如果想要获取某一时刻，需要自己通过boolean去判断是否需要获取回调数据

最后，记得取消监听，因为我是在activity中去注册的，所以取消注册也是在activity中去做：

protected void onStop() {        super.onStop();        sensorUtils.UnRegisterSensor();    }
