Android xyz三轴学习

参照sample做了一个sensor demo

sensorMgr = (SensorManager) getSystemService(SENSOR_SERVICE);
		Sensor sensor = sensorMgr.getDefaultSensor(Sensor.TYPE_ACCELEROMETER);
		SensorEventListener lsn = new SensorEventListener() {
			public void onSensorChanged(SensorEvent e) {
				x = e.values[SensorManager.DATA_X];
				y = e.values[SensorManager.DATA_Y];
				z = e.values[SensorManager.DATA_Z];
				
				Tvx.setText("X轴：" + x + "");
				Tvy.setText("Y轴：" + y + "");
				Tvz.setText("Z轴：" + z + "");
			}

			public void onAccuracyChanged(Sensor s, int accuracy) {
			}
		};
		// 注册listener，第三个参数是检测的精确度
		sensorMgr
				.registerListener(lsn, sensor, SensorManager.SENSOR_DELAY_GAME);
