检测手机​​旋转（运动） [英] Detecting phone rotation (movement)

问题描述

这是可以检测手机运动就像在图像上是什么时候？什么是这android的名字？

Is this possible to detect when the phone moves like on the image? What is the name of this in android?

是否有处理这种事情无论如何？一年前，我看到了一个应用程序有一个指南针，它是实时的工作。

Is there any event that handle this kind of things? A year ago I saw an App with a compass and it was working in real time.

谢谢！

我希望这code有助于

I hope that this code will help

package com.exercise.AndroidSensorEventListener;

import java.util.List;

import android.app.Activity;
import android.content.Context;
import android.hardware.Sensor;
import android.hardware.SensorEvent;
import android.hardware.SensorEventListener;
import android.hardware.SensorManager;
import android.os.Bundle;
import android.widget.TextView;
import android.widget.Toast;

public class AndroidSensorEventListener extends Activity {
 private static SensorManager mySensorManager;
 private boolean sersorrunning;

   @Override
   public void onCreate(Bundle savedInstanceState) {
       super.onCreate(savedInstanceState);
       setContentView(R.layout.main);

       mySensorManager = (SensorManager)getSystemService(Context.SENSOR_SERVICE);
       List<Sensor> mySensors = mySensorManager.getSensorList(Sensor.TYPE_ORIENTATION);

       if(mySensors.size() > 0){
        mySensorManager.registerListener(mySensorEventListener, mySensors.get(0), SensorManager.SENSOR_DELAY_NORMAL);
        sersorrunning = true;
        Toast.makeText(this, "Start ORIENTATION Sensor", Toast.LENGTH_LONG).show();
       }
       else{
        Toast.makeText(this, "No ORIENTATION Sensor", Toast.LENGTH_LONG).show();
        sersorrunning = false;
        finish();
       }

   }

   private SensorEventListener mySensorEventListener = new SensorEventListener() {

  @Override
  public void onSensorChanged(SensorEvent event) {
           System.out.println("Azimuth: " + String.valueOf(event.values[0]));
           System.out.println("Pitch: " + String.valueOf(event.values[1]));
           System.out.println("Roll: " + String.valueOf(event.values[2]));
  }

  @Override
  public void onAccuracyChanged(Sensor sensor, int accuracy) {
  }
 };

 @Override
 protected void onDestroy() {
  super.onDestroy();

  if(sersorrunning){
   mySensorManager.unregisterListener(mySensorEventListener);
   Toast.makeText(AndroidSensorEventListener.this, "unregisterListener", Toast.LENGTH_SHORT).show();
  }
 }
}
