leidiqiu

Android 开发包标准有8个传感器：
 

• Sensor.TYPE_ACCELEROMETER
  
  
  
  • 加速度计 (X, Y, Z) m/s2
    
  
  
• Sensor.TYPE_GYROSCOPE
  
  
  
  • 陀螺仪 (X, Y, Z) degrees
    
  
  
• Sensor.TYPE_LIGHT
  
  
  
  • 光照 (single) lux
    
  
  
• Sensor.TYPE_MAGNETIC_FIELD
  
  
  
  • 磁力计 (X, Y, Z) microteslas
    
  
  
• Sensor.TYPE_ORIENTATION
  
  
  
  • 方位传感器 (X, Y, Z) degrees
    
  
  
• Sensor.TYPE_PRESSURE
  
  
  
  • 压力传感器 (single) kilopascals 测量加在手机设备上的压力
    
  
  
• Sensor.TYPE_PROXIMITY
  
  
  
  • 距离传感器 (single) meters 典型应用为接听电话时，根据光照，声音估计距离
    
  
  
• Sensor.TYPE_TEMPERATURE
  
  
  
  • 温度传感器 (single) degrees Celsius 电池温度，或是具体传感器温度，看具体实现
    
  
  

手机型号不同，硬件实现有所区别。
 
读取传感器代码如下：
package com.ldq.sensor;import java.util.List;import android.app.Activity;import android.hardware.Sensor;import android.hardware.SensorManager;import android.os.Bundle;import android.widget.LinearLayout;import android.widget.TextView;public class ExSensor extends Activity {private LinearLayout layout;/** Called when the activity is first created. */@Overridepublic void onCreate(Bundle savedInstanceState) {super.onCreate(savedInstanceState);setContentView(R.layout.main);layout = (LinearLayout) findViewById(R.id.LinearLayout01);SensorManager sm = (SensorManager) getSystemService(SENSOR_SERVICE);List<Sensor> list = sm.getSensorList(Sensor.TYPE_ALL);TextView text = new TextView(this);text.setText("传感器数量：" + list.size());layout.addView(text);TextView[] name = new TextView[list.size()];for (int i = 0; i < list.size(); i++) {name = new TextView(this);name.setText((i + 1) + " : " + list.get(i).getName());layout.addView(name);}}}
