【android】：android获得手机内传感器类型

方法很简单，代码把下面的覆盖onCreate函数，然后对SensorManager以及TextView的声明就好了

主要的过程就是：获得了传感器组，然后通过传感器组来判断是否有该对象，并且进行相关判定的过程

函数代码如下：

protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
tx1 = (TextView) findViewById(R.id.textview);
sensorManager = (SensorManager) getSystemService(Context.
SENSOR_SERVICE);
//  @SuppressWarnings("deprecation")
/*  Sensor sensor = sensorManager.getDefaultSensor(Sensor.TYPE_AMBIENT_TEMPERATURE);
sensorManager.registerListener(listener, sensor, SensorManager.
SENSOR_DELAY_NORMAL);*/
List<Sensor> allSensors = sensorManager.getSensorList(Sensor.TYPE_ALL);

//显示有多少个传感器
tx1.setText("经检测该手机有" + allSensors.size() + "个传感器，他们分别是：\n");

//显示每个传感器的具体信息
for (Sensor s : allSensors) {

String tempString = "\n" + "  设备名称：" + s.getName() + "\n" + "  设备版本：" + s.getVersion() + "\n" + "  供应商："
+ s.getVendor() + "\n";

switch (s.getType()) {
case Sensor.TYPE_ACCELEROMETER:
tx1.setText(tx1.getText().toString() + s.getType() + " 加速度传感器accelerometer" + tempString);
break;
case Sensor.TYPE_GYROSCOPE:
tx1.setText(tx1.getText().toString() + s.getType() + " 陀螺仪传感器gyroscope" + tempString);
break;
case Sensor.TYPE_LIGHT:
tx1.setText(tx1.getText().toString() + s.getType() + " 环境光线传感器light" + tempString);
break;
case Sensor.TYPE_MAGNETIC_FIELD:
tx1.setText(tx1.getText().toString() + s.getType() + " 电磁场传感器magnetic field" + tempString);
break;
case Sensor.TYPE_ORIENTATION:
tx1.setText(tx1.getText().toString() + s.getType() + " 方向传感器orientation" + tempString);
break;
case Sensor.TYPE_PRESSURE:
tx1.setText(tx1.getText().toString() + s.getType() + " 压力传感器pressure" + tempString);
break;
case Sensor.TYPE_PROXIMITY:
tx1.setText(tx1.getText().toString() + s.getType() + " 距离传感器proximity" + tempString);
break;
case Sensor.TYPE_TEMPERATURE:
tx1.setText(tx1.getText().toString() + s.getType() + " 温度传感器temperature" + tempString);
break;
default:
tx1.setText(tx1.getText().toString() + s.getType() + " 未知传感器" + tempString);
break;
}
}
}
