Android代碼----傳感器-----測試手機支持那幾種傳感

一個小小Demo檢測手機支持那幾種傳感：

具體代碼如下：

[Java代碼]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);// 獲得傳感器列表
 }
 class ButtonListener implements OnClickListener {
  public void onClick(View v) {
   str = new StringBuffer();
   str.append("該手機有" + allSensors.size() + "個傳感器,分別是:\n");
   for (int i = 0; i < allSensors.size(); i++) {
    s = allSensors.get(i);
    str.append("設備名稱:" + s.getName() + "\n");
    str.append("設備版本:" + s.getVersion() + "\n");
    str.append("通用類型號:" + s.getType() + "\n");
    str.append("設備商名稱:" + s.getVendor() + "\n");
    str.append("傳感器功耗:" + s.getPower() + "\n");
    str.append("傳感器分辨率:" + s.getResolution() + "\n");
    str.append("傳感器最大量程:" + s.getMaximumRange() + "\n");
    switch (s.getType()) {
    case Sensor.TYPE_ACCELEROMETER:
     str.append(i + "加速度傳感器");
     break;
    case Sensor.TYPE_GYROSCOPE:
     str.append(i + "陀螺儀傳感器");
     break;
    case Sensor.TYPE_LIGHT:
     str.append(i + "環境光線傳感器");
     break;
    case Sensor.TYPE_MAGNETIC_FIELD:
     str.append(i + "電磁場傳感器");
     break;
    case Sensor.TYPE_ORIENTATION:
     str.append(i + "方向傳感器");
     break;
    case Sensor.TYPE_PRESSURE:
     str.append(i + "壓力傳感器");
     break;
    case Sensor.TYPE_PROXIMITY:
     str.append(i + "距離傳感器");
     break;
    case Sensor.TYPE_TEMPERATURE:
     str.append(i + "溫度傳感器");
     break;
    default:
     str.append(i + "未知傳感器");
     break;
    }
   }
   show.setText(str);
  }
 }
}
