得到可用的Sensors List列表

public void onCreate(Bundle savedInstanceState) { 
    super.onCreate(savedInstanceState); 
    setContentView(R.layout.main); 
    // Get the texts fields of the layout and setup to invisible 
    mSensorsTot   = (TextView) findViewById(R.id.sensoritot); 
    mSensorAvailables  = (TextView) findViewById(R.id.sensoridisponibili); 
 
    // Get the SensorManager  
    mSensorManager= (SensorManager) getSystemService(SENSOR_SERVICE); 
 
    // List of Sensors Available 
    List<Sensor> msensorList = mSensorManager.getSensorList(Sensor.TYPE_ALL ); 
 
    // Print how may Sensors are there 
    mSensorsTot.setText(msensorList.size()+" "+this.getString(R.string.sensors)+"!"); 
 
    // Print each Sensor available using sSensList as the String to be printed 
    String sSensList = new String(""); 
    Sensor tmp; 
    int x,i; 
    for (i=0;i<msensorList.size();i++){ 
     tmp = msensorList.get(i); 
     sSensList = " "+sSensList+tmp.getName(); // Add the sensor name to the string of sensors available 
    } 
    // if there are sensors available show the list 
    if (i>0){ 
     sSensList = getString(R.string.sensors)+":"+sSensList; 
     mSensorAvailables.setText(sSensList); 
    } 
} 

 这里呢要注意使用Sensor.TYPE_ALL 而不是使用废棋的SensorManager.SENSOR_ALL他对部分机器不使用

把我好郁闷
