切换为横向之前，活动以竖向闪烁

问题描述

我正在创建一个android游戏，其中每个活动都在xml清单文件中设置为横向.

I am creating an android game where every activity is set to be in landscape in the xml manifest file.

但是，有时在进行一项新活动时，它会以纵向闪烁一秒钟，然后再校正为横向.

However, sometimes when going to a new activity it flashes up in portrait for a second before correcting to landscape.

有人有任何一般原因吗?

Does anyone have any generic reason why this might be?

使用ScheduledFuture太早退出关卡完成屏幕时会发生

It happens when exiting the level completion screen too early which uses a ScheduledFuture

谢谢安迪

推荐答案

尝试添加 screenOrientation 到您的清单:

Try to add screenOrientation to your manifest:

<activity android:screenOrientation="sensorLandscape" ...>

我建议使用sensorLandscape，以便用户可以选择将设备向右还是向左旋转.

I suggest to use sensorLandscape so the user can choose if the divice is rotated to the right or the left.
