Root Cause

GLSurfaceView is used without setting a Renderer via setRenderer(), so no OpenGL rendering context is created.

generic

中文

使用 GLSurfaceView 时未通过 setRenderer() 设置渲染器，因此没有创建 OpenGL 渲染上下文。

Workarounds

  1. 95% success Call setRenderer() with a valid Renderer implementation in onCreate() or after view initialization 
    Call setRenderer() with a valid Renderer implementation in onCreate() or after view initialization
  2. 90% success Ensure the Renderer class implements GLSurfaceView.Renderer and overrides onSurfaceCreated, onDrawFrame, onSurfaceChanged 
    Ensure the Renderer class implements GLSurfaceView.Renderer and overrides onSurfaceCreated, onDrawFrame, onSurfaceChanged
  3. 85% success If using a custom view, call setRenderer in the constructor after super() 
    If using a custom view, call setRenderer in the constructor after super()

中文步骤

  1. 在 onCreate() 或视图初始化后使用有效的 Renderer 实现调用 setRenderer()
  2. 确保 Renderer 类实现 GLSurfaceView.Renderer 并重写 onSurfaceCreated、onDrawFrame、onSurfaceChanged
  3. 如果使用自定义视图，在构造函数中 super() 之后调用 setRenderer()

Dead Ends

Common approaches that don't work:

  1. 90% fail

    requestRender() requires a renderer to be set; without it, the call is ignored and the error persists.

  2. 60% fail

    setRenderer() must be called on the main thread; doing so on another thread may cause race conditions or silent failure.

  3. 80% fail

    XML declaration alone does not call setRenderer(); it must be done in code after creating the view.
