GLSurfaceView 中的方向更改问题

发布于 2024-12-03 14:18:38 字数 5897 浏览 0 评论 0原文

我正在使用 Android openGLES1.0 旋转多边形。如果我连续更改设备的方向（从横向到纵向，反之亦然）2.3 次，我的活动 GLSurfaceView 就会消失。它会导致之前的活动（屏幕）。logcat 显示以下消息。 请帮我。

这是我的日志：

您可以禁用方向更改。不过，根据您正在做的事情，这可能不可行。

You could disable the orientation change. Depending upon what you are doing though, this may not be feasible.

如果您使用的是 API 3+，请尝试使用 view.setPreserveEGLContextOnPause(true)

Try using view.setPreserveEGLContextOnPause(true) if you're using API 3+
