进阶篇－安卓系统：3.初识安卓手机内置传感器

在第二代智能手机问世之后，安卓手机中的传感器就变得越来越多了。

这次笔记就认识一下安卓内置传感器的种类吧。

如果想要获取安卓手机中所有的内置传感器的名字：

import android.hardware.Sensor;
import android.hardware.SensorManager;
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;

import java.util.List;

public class MainActivity extends AppCompatActivity {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        SensorManager sensorManager = (SensorManager) getSystemService(SENSOR_SERVICE);
        List<Sensor> sensors = sensorManager.getSensorList(Sensor.TYPE_ALL);
        for(Sensor sensor: sensors){
            System.out.println(sensor.getName());
        }
    }
}

运行结果：

我用的测试机是小米2s，上面的运行结果打印出了小米2s内置的所有传感器。
