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;
}
}
