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);

}

}

}
