android获取传感器列表

本文介绍如何获取android设备所支持的传感器列表。

目前，android 4.4 （API等级19）支持以下传感器：

获取传感器列表的代码如下：

package com.example.androidtest;import java.util.List;import android.os.Bundle;import android.annotation.SuppressLint;import android.app.Activity;import android.content.Context;import android.hardware.Sensor;import android.hardware.SensorManager;import android.view.Menu;public class MainActivity extends Activity {@Overrideprotected void onCreate(Bundle savedInstanceState) {super.onCreate(savedInstanceState);setContentView(R.layout.activity_main);getSensorList();}@SuppressLint("NewApi")private void getSensorList() {// 获取传感器管理器SensorManager sensorManager = (SensorManager) getSystemService(Context.SENSOR_SERVICE);// 获取全部传感器列表List<Sensor> sensors = sensorManager.getSensorList(Sensor.TYPE_ALL);// 打印每个传感器信息StringBuilder strLog = new StringBuilder();int iIndex = 1;for (Sensor item : sensors) {strLog.append(iIndex + ".");strLog.append("Sensor Type - " + item.getType() + "\r\n");strLog.append("Sensor Name - " + item.getName() + "\r\n");strLog.append("Sensor Version - " + item.getVersion() + "\r\n");strLog.append("Sensor Vendor - " + item.getVendor() + "\r\n");strLog.append("Maximum Range - " + item.getMaximumRange() + "\r\n");strLog.append("Minimum Delay - " + item.getMinDelay() + "\r\n");strLog.append("Power - " + item.getPower() + "\r\n");strLog.append("Resolution - " + item.getResolution() + "\r\n");strLog.append("\r\n");iIndex++;}System.out.println(strLog.toString());}@Overridepublic boolean onCreateOptionsMenu(Menu menu) {// Inflate the menu; this adds items to the action bar if it is present.getMenuInflater().inflate(R.menu.activity_main, menu);return true;}}

以三星Note3为例，其支持的传感器如下：
