Android 如何从传感器确定设备方向
我的活动锁定在风景上。但我仍然需要知道设备的方向。所以我选择使用传感器。我有以下代码Android 如何从传感器确定设备方向,android,orientation,screen-orientation,android-sensors,android-orientation,Android,Orientation,Screen Orientation,Android Sensors,Android Orientation,我的活动锁定在风景上。但我仍然需要知道设备的方向。所以我选择使用传感器。我有以下代码 sensorManager = (SensorManager) getSystemService(SENSOR_SERVICE); sensorManager.registerListener(this, sensorManager.getDefaultSensor(Sensor.TYPE_ORIENTATION), SensorManager.SENSOR_DELAY_NORMAL); ... @Overri

float azimuth = values[0];
float pitch = values[1];

传感器更改时的公共无效(传感器事件){
float[]值=event.values;
//运动
浮动方位角=值[0];
浮动节距=值[1];
浮动辊=数值[2];
如果((-110如果横向与纵向方向是您所需要的,那么音高值应该足够。根据您的具体需要,音高值可能并不完美。但根据我的理解,您可以简单地使用音高。因此,您可以完全按照现有的方式使用音高值,只需忽略滚动。在oncreate
中实例化方向ventlister
OrientationEventListener orientationEventListener = new OrientationEventListener(this)
{
@Override
public void onOrientationChanged(int orientation)
{
Log.d(TAG, "orientation = " + orientation);
}
};
orientationEventListener.enable();
使用方向值,您可以确定设备是纵向还是横向。您是否尝试过自己处理配置更改?-添加configChanges:orientation
以显示,并实现onConfigurationChanged
,然后您可能会得到不起作用的newConfig.orientation
方向已锁定,配置更改事件没有意义。您必须使用传感器。然后我建议这正是我需要的:)
