传感器---方向传感

一个简单的小Demo测试手机方向传感：

具体代码如下：

[Java代码]Sample.java

package com.example.test_sensor_orientation;

import org.openintents.sensorsimulator.hardware.Sensor;
import android.app.Activity;
import android.hardware.SensorManager;
import android.os.Bundle;
import android.widget.TextView;

public  class Sample extends Activity implements  android.hardware.SensorEventListener {
	
	TextView myTextView1;
	TextView myTextView2;
	TextView myTextView3;
	
	private SensorManager mySensorManager;

	@Override
	public void onCreate(Bundle savedInstanceState) {
		super.onCreate(savedInstanceState);
		setContentView(R.layout.main);
		myTextView1 = (TextView) findViewById(R.id.myTextView1);
		myTextView2 = (TextView) findViewById(R.id.myTextView2);
		myTextView3 = (TextView) findViewById(R.id.myTextView3);
		mySensorManager = (SensorManager) getSystemService(SENSOR_SERVICE);

	}

	@Override
	protected void onResume() {
		mySensorManager.registerListener(
				this,
				mySensorManager.getDefaultSensor(Sensor.TYPE_ORIENTATION),
				SensorManager.SENSOR_DELAY_GAME
				);
		super.onResume();
	}

	@Override
	protected void onStop() {
		// TODO Auto-generated method stub
		mySensorManager.unregisterListener(this);
		super.onStop();
	}
	@Override
	protected void onPause() {
		mySensorManager.unregisterListener(this);
		super.onPause();
	}

	@Override
	public void onAccuracyChanged(android.hardware.Sensor sensor, int accuracy) {
		// TODO Auto-generated method stub
		
	}

	@Override
	public void onSensorChanged(android.hardware.SensorEvent event) {
		// TODO Auto-generated method stub
		float[] values = event.values;
		int sensorType = event.sensor.TYPE_ORIENTATION;
		if (sensorType == Sensor.TYPE_ORIENTATION) {
			myTextView1.setText("Yaw为："+values[0]); 
			myTextView2.setText("Pitch为："+values[1]); 
			myTextView3.setText("Roll为："+values[2]); 
		}
	}

}

[XML代码]main.xml
