Android中传感器的主要应用

 

 

 

 

 

 

 

 

//列出所有传感器类型：
public class MainActivity extends ActionBarActivity {
    private TextView tvSensor;
    private SensorManager sManager;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.fragment_main);
        tvSensor = (TextView) findViewById(R.id.tv);
        // 获得传感器服务
        sManager = (SensorManager) getSystemService(SENSOR_SERVICE);
        // 获得所有类型的硬件传感器
        List<Sensor> sensors = sManager.getSensorList(Sensor.TYPE_ALL);
        for (Sensor sensor : sensors) {
            tvSensor.append(sensor.getName() + "\n");

        }

    }
