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 {

	@Override
	protected 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());
	}

	@Override
	public 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;
	}

}
