本文实例讲述了Android开发获取传感器数据的方法。分享给大家供大家参考，具体如下：
package mobile.android.sensor; import java.util.List; import android.app.Activity; import android.hardware.Sensor; import android.hardware.SensorEvent; import android.hardware.SensorEventListener; import android.hardware.SensorManager; import android.os.Bundle; import android.widget.TextView; public class Main extends Activity implements SensorEventListener { private TextView tvAccelerometer; private TextView tvMagentic; private TextView tvLight; private TextView tvOrientation; private TextView tvSensors; @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.main); // 获得SensorManager对象 SensorManager sensorManager = (SensorManager) getSystemService(SENSOR_SERVICE); // 注册加速度传感器 sensorManager.registerListener(this, sensorManager.getDefaultSensor(Sensor.TYPE_ACCELEROMETER), SensorManager.SENSOR_DELAY_FASTEST); // 注册磁场传感器 sensorManager.registerListener(this, sensorManager.getDefaultSensor(Sensor.TYPE_MAGNETIC_FIELD), SensorManager.SENSOR_DELAY_FASTEST); // 注册光线传感器 sensorManager.registerListener(this, sensorManager.getDefaultSensor(Sensor.TYPE_LIGHT), SensorManager.SENSOR_DELAY_FASTEST); // 注册方向传感器 sensorManager.registerListener(this, sensorManager.getDefaultSensor(Sensor.TYPE_ORIENTATION), SensorManager.SENSOR_DELAY_FASTEST); tvAccelerometer = (TextView) findViewById(R.id.tvAccelerometer); tvMagentic = (TextView) findViewById(R.id.tvMagentic); tvLight = (TextView) findViewById(R.id.tvLight); tvOrientation = (TextView) findViewById(R.id.tvOrientation); tvSensors = (TextView) findViewById(R.id.tvSensors); // 获得当前手机支持的所有传感器 List<Sensor> sensors = sensorManager.getSensorList(Sensor.TYPE_ALL); for (Sensor sensor : sensors) { // 输出当前传感器的名称 tvSensors.append(sensor.getName() + "\n"); } } @Override public void onSensorChanged(SensorEvent event) { // 通过getType方法获得当前传回数据的传感器类型 switch (event.sensor.getType()) { case Sensor.TYPE_ACCELEROMETER: // 处理加速度传感器传回的数据 String accelerometer = "加速度\n" + "X：" + event.values[0] + "\n" + "Y:" + event.values[1] + "\n" + "Z:" + event.values[2] + "\n"; tvAccelerometer.setText(accelerometer); break; case Sensor.TYPE_LIGHT: // 处理光线传感器传回的数据 tvLight.setText("亮度：" + event.values[0]); break; case Sensor.TYPE_MAGNETIC_FIELD: // 处理磁场传感器传回的数据 String magentic = "磁场\n" + "X：" + event.values[0] + "\n" + "Y:" + event.values[1] + "\n" + "Z:" + event.values[2] + "\n"; tvMagentic.setText(magentic); break; case Sensor.TYPE_ORIENTATION: // 处理方向传感器传回的数据 String orientation = "方向\n" + "X：" + event.values[0] + "\n" + "Y:" + event.values[1] + "\n" + "Z:" + event.values[2] + "\n"; tvOrientation.setText(orientation); break; } } @Override public void onAccuracyChanged(Sensor sensor, int accuracy) { } }
PS：这里获得的只是传感器采集数据，还需要对数据分析，变成有用的信息。
