Android代码----传感器-----测试手机支持那几种传感

一个小小Demo检测手机支持那几种传感：

具体代码如下：

[Java代码]DemoSensorActivity.java

package com.example.testsensor;  import java.util.List;  import android.app.Activity;  import android.content.Context;  import android.hardware.Sensor;  import android.hardware.SensorManager;  import android.os.Bundle;  import android.view.View;  import android.view.View.OnClickListener;  import android.widget.Button;  import android.widget.TextView;  public class DemoSensorActivity extends Activity {   private Button button;   private TextView show;   private SensorManager sm;   private StringBuffer str;   private List<Sensor> allSensors;   private Sensor s;   @Override   public void onCreate(Bundle savedInstanceState) {    super.onCreate(savedInstanceState);    setContentView(R.layout.main);    button = (Button) findViewById(R.id.button);    show = (TextView) findViewById(R.id.show);    button.setOnClickListener(new ButtonListener());    sm = (SensorManager) getSystemService(Context.SENSOR_SERVICE);    allSensors = sm.getSensorList(Sensor.TYPE_ALL);// 获得传感器列表   }   class ButtonListener implements OnClickListener {    public void onClick(View v) {     str = new StringBuffer();     str.append("该手机有" + allSensors.size() + "个传感器,分别是:\n");     for (int i = 0; i < allSensors.size(); i++) {      s = allSensors.get(i);      str.append("设备名称:" + s.getName() + "\n");      str.append("设备版本:" + s.getVersion() + "\n");      str.append("通用类型号:" + s.getType() + "\n");      str.append("设备商名称:" + s.getVendor() + "\n");      str.append("传感器功耗:" + s.getPower() + "\n");      str.append("传感器分辨率:" + s.getResolution() + "\n");      str.append("传感器最大量程:" + s.getMaximumRange() + "\n");      switch (s.getType()) {      case Sensor.TYPE_ACCELEROMETER:       str.append(i + "加速度传感器");       break;      case Sensor.TYPE_GYROSCOPE:       str.append(i + "陀螺仪传感器");       break;      case Sensor.TYPE_LIGHT:       str.append(i + "环境光线传感器");       break;      case Sensor.TYPE_MAGNETIC_FIELD:       str.append(i + "电磁场传感器");       break;      case Sensor.TYPE_ORIENTATION:       str.append(i + "方向传感器");       break;      case Sensor.TYPE_PRESSURE:       str.append(i + "压力传感器");       break;      case Sensor.TYPE_PROXIMITY:       str.append(i + "距离传感器");       break;      case Sensor.TYPE_TEMPERATURE:       str.append(i + "温度传感器");       break;      default:       str.append(i + "未知传感器");       break;      }     }     show.setText(str);    }   }  }
