Android OrientationEventListener SensorManager.SENSOR_DELAY_NORMAL 必要性 [英] Android OrientationEventListener SensorManager.SENSOR_DELAY_NORMAL Necessity

问题描述

来自文档，它说:

使用默认值 SENSOR_DELAY_NORMAL 进行简单的屏幕方向变化检测.

Use the default value of SENSOR_DELAY_NORMAL for simple screen orientation change detection.

这是否意味着如果我在构造函数中不包含传感器速率，它仍然会应用SENSOR_DELAY_NORMAL?

Does it mean that if I don't include the sensor rate in the constructor, it will still apply the SENSOR_DELAY_NORMAL?

换句话说，这两个是否相同:

In other words, are this two the same:

OrientationEventListener(context)

OrientationEventListener(context, Sensor.SENSOR_DELAY_NORMAL)

PS:我用于简单的屏幕方向变化检测.

推荐答案

根据 官方源码，前者的构造函数定义如下，

According to the official source code, the former constructor is defined as follows,

/**
 * Creates a new OrientationEventListener.
 * 
 * @param context for the OrientationEventListener.
 */
public OrientationEventListener(Context context) {
    this(context, SensorManager.SENSOR_DELAY_NORMAL);
}

所以，完全等同于后者.你可以随意使用.

So, it's completely equivalent to the latter. You can use whichever you like.
