android - 检测手机旋转(运动)

Question

这是否可以检测到手机何时像图片上那样移动？这个在android中叫什么名字？

是否有处理此类事情的事件？一年前，我看到一个带指南针的应用程序，它可以实时运行。

谢谢!

我希望这段代码能有所帮助

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();
  }
 }
}
