Android中传感器的主要应用
 1 //列出所有传感器类型：
 2 public class MainActivity extends ActionBarActivity {
 3     private TextView tvSensor;
 4     private SensorManager sManager;
 5 
 6     @Override
 7     protected void onCreate(Bundle savedInstanceState) {
 8         super.onCreate(savedInstanceState);
 9         setContentView(R.layout.fragment_main);
10         tvSensor = (TextView) findViewById(R.id.tv);
11         // 获得传感器服务
12         sManager = (SensorManager) getSystemService(SENSOR_SERVICE);
13         // 获得所有类型的硬件传感器
14         List<Sensor> sensors = sManager.getSensorList(Sensor.TYPE_ALL);
15         for (Sensor sensor : sensors) {
16             tvSensor.append(sensor.getName() + "
");
