我在运行时连续获取加速度计值(即)X 和 Y 值。我的问题是,当加速度计的值在移动设备中发生变化时,应根据变化累积相应的值。
这是我的代码:
public class MainActivity extends Activity implements SensorEventListener {
private SensorManager sensorManager;
private float accumulation_x = 0;
private float accumulation_y = 0;
private float accumulation_z = 0;
private TextView acessTextview, angleTextview;
private float value;
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
findViewById();
sensorManager = (SensorManager) getSystemService(SENSOR_SERVICE);
sensorManager.registerListener(this,
sensorManager.getDefaultSensor(Sensor.TYPE_ACCELEROMETER),
SensorManager.SENSOR_DELAY_NORMAL);
}
public void onAccuracyChanged(Sensor sensor, int accuracy) {
}
public void onSensorChanged(SensorEvent event) {
if (event.sensor.getType() == Sensor.TYPE_ACCELEROMETER) {
int count = 1;
while(count!=0){
float x = (float) 0.9887777;
float y = (float) 0.187359372;
float z = (float) 0.0228636;
float X_axis = (float) (x + (0.02724095));
float Y_axis = (float) (y + (-0.027792556));
float Z_axis = (float) (z - (0.105689));
accumulation_x = accumulation_x + X_axis;
accumulation_y = accumulation_y + Y_axis;
accumulation_z = accumulation_z + Z_axis;
value = (y / z);
float angle = (float) Math.toDegrees(Math.atan(value));
angleTextview.setText("Angle:" + angle);
acessTextview.setText("accumulation_x :" + X_axis + "\n"
+ "accumulation_y :" + Y_axis + "\n"
+ "accumulation_z :" + Z_axis);
count++;
}
}
}
private void findViewById() {
// TODO Auto-generated method stub
acessTextview = (TextView) findViewById(R.id.accessTextview);
angleTextview = (TextView) findViewById(R.id.angleTextview);
}
}
