我正在做一个必须将加速度计数据记录在记录文件中的项目。任何人都可以帮助我使用以下代码吗?为了记录加速度计数据,应在以下代码中添加哪些 android 代码?我可能希望每 10 毫秒获取一次数据。任何帮助是极大的赞赏。
package com.example.helloandroid;
import android.app.Activity;
import android.hardware.Sensor;
import android.hardware.SensorEvent;
import android.hardware.SensorEventListener;
import android.hardware.SensorManager;
import android.os.Bundle;
import android.widget.TextView;
public class AccActivity extends Activity implements SensorEventListener {
private SensorManager sensorManager;
TextView xCoor; // declare X axis object
TextView yCoor; // declare Y axis object
TextView zCoor; // declare Z axis object
@Override
public void onCreate(Bundle savedInstanceState){
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
xCoor=(TextView)findViewById(R.id.xcoor); // create X axis object
yCoor=(TextView)findViewById(R.id.ycoor); // create Y axis object
zCoor=(TextView)findViewById(R.id.zcoor); // create Z axis object
sensorManager=(SensorManager)getSystemService(SENSOR_SERVICE);
// add listener. The listener will be HelloAndroid (this) class
sensorManager.registerListener(this,
sensorManager.getDefaultSensor(Sensor.TYPE_ACCELEROMETER),
SensorManager.SENSOR_DELAY_NORMAL);
/* More sensor speeds (taken from api docs)
SENSOR_DELAY_FASTEST get sensor data as fast as possible
SENSOR_DELAY_GAME rate suitable for games
SENSOR_DELAY_NORMAL rate (default) suitable for screen orientation changes
*/
}
public void onAccuracyChanged(Sensor sensor,int accuracy){
}
public void onSensorChanged(SensorEvent event){
// check sensor type
if(event.sensor.getType()==Sensor.TYPE_ACCELEROMETER){
// assign directions
float x=event.values[0];
float y=event.values[1];
float z=event.values[2];
xCoor.setText("X: "+x);
yCoor.setText("Y: "+y);
zCoor.setText("Z: "+z);
}
}
}
