android:设备旋转时禁用opengl ES上下文切换

问题描述

我有一个android全屏opengl es应用程序.

i have an android fullscreen opengl es app.

当设备从纵向旋转到横向并向后旋转时，gl上下文会被破坏并重新创建.

when the device is rotate from portrait to landscape and back the gl context is destroyed and recreated.

有办法避免这种情况吗?即总是保持肖像或风景?

is there a way to avoid this? i.e. always stay in portrait or landscape?

我已经在活动中包含以下代码:

edit: i already have this code in my activity:

@Override
protected void onResume()
{
    super.onResume();
    mGLSurfaceView.onResume();
}

@Override
protected void onPause()
{
    super.onPause();
    mGLSurfaceView.onPause();
}

推荐答案

不幸的是，直到API级别11 (3.0) GLSurfaceView 始终会破坏GL上下文.对于11岁或以上的人，您可以 setPreserveEGLContextOnPause (boolean preserveOnPause) .

Unfortunately until API Level 11 (3.0) GLSurfaceView will always destroy the GL context. For 11 and higher you have the ability to setPreserveEGLContextOnPause (boolean preserveOnPause).

可以通过更改GLSurfaceView的来源来解决此问题，但是遇到任何问题将很难获得其他人的帮助.

There are ways around this by changing the source of GLSurfaceView but any problems you encounter it will be a lot harder to get help from others.
