代码很简单，自己看就能明白，只是为了练习一下Sensor类的使用方法。算是一个练习.

package mars.com; 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);   } } }
