進階篇－安卓系統：3.初識安卓手機內建感應器

標籤：

在第二代智能手機問世之後，安卓手機中的感應器就變得越來越多了。

這次筆記就認識一下安卓內建感應器的種類吧。

 

如果想要擷取安卓手機中所有的內建感應器的名字：

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());        }    }}

運行結果：

我用的測試機是小米2s，上面的運行結果列印出了小米2s內建的所有感應器。
