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 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);
}
}
}
