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); } } }
