基于Android 的手机传感器检测

效果展示：

可借用代码部分：

首先在布局文件写一个textView来显示他跳的数值

 在主文件中首先先定义一下

  private TextView mTextViewGravity;
 private SensorEventListener mEventListenerGravity;

 绑定按钮

    mTextViewGravity= (TextView) findViewById(R.id.text_gravity);

填写检测传感器的代码：

 mSensorManager = (SensorManager) getSystemService(SENSOR_SERVICE);
        initListeners();
 private  void initListeners(){
        final DecimalFormat df=new DecimalFormat("0.0");
        mEventListenerAccelerometer= new SensorEventListener() {
            //加速度传感器
            @Override
            public void onSensorChanged(SensorEvent event) {
                float[] values =event.values ;
                mTextViewAccelerometer . setText("Accelerometer:"+ df . format(values[0])
                        + ","+ df.format(values[1]) +","+ df.format(values[2]));
            }
            @Override
            public void onAccuracyChanged(Sensor sensor, int accuracy) {

            }
            };

 填写可以让他关闭的代码

 protected void onResume() {
                    super.onResume();
                    mSensorManager.registerListener(mEventListenerAccelerometer,
                            mSensorManager.getDefaultSensor(Sensor.TYPE_ACCELEROMETER),
                            SensorManager.SENSOR_DELAY_NORMAL);
                    mSensorManager.registerListener(mEvenListenerLinearAcceleration,
                            mSensorManager.getDefaultSensor(Sensor.TYPE_LINEAR_ACCELERATION),
                            SensorManager.SENSOR_DELAY_NORMAL);
                    mSensorManager.registerListener(mEventListenerGravity,
                            mSensorManager.getDefaultSensor(Sensor.TYPE_GRAVITY),
                            SensorManager.SENSOR_DELAY_NORMAL);
                }
                    @Override
                    protected void onStop() {
                        mSensorManager.unregisterListener(mEventListenerAccelerometer);
                        mSensorManager.unregisterListener(mEvenListenerLinearAcceleration);
                        mSensorManager.unregisterListener(mEventListenerGravity);
                        super.onStop();


                    }
}
