Question

我需要GLSurfaceView来渲染一些东西，这里让我感到困惑：我首先调用setEGLContextClientVersion（2），但是在onSurfaceCreated（）中，我调用gl.glHint（GL10.GL_PERSPECTIVE_CORRECTION_HINT，GL10.GL_FASTEST），仅获得glError，如下所示：

这是代码：

public void onSurfaceCreated(GL10 gl, EGLConfig config) {

    gl.glHint(GL10.GL_PERSPECTIVE_CORRECTION_HINT, GL10.GL_FASTEST);

    gl.glClearColor(0.5f, 0.5f, 0.5f, 1);
    gl.glShadeModel(GL10.GL_FLAT);
    gl.glDisable(GL10.GL_DEPTH_TEST);
    gl.glEnable(GL10.GL_TEXTURE_2D);
    gl.glDisable(GL10.GL_DITHER);
    gl.glDisable(GL10.GL_LIGHTING);

    gl.glEnable(GL10.GL_TEXTURE_2D);
    gl.glGenTextures(1, mTextureNameWorkspace, 0);

    int textureName = mTextureNameWorkspace[0];
    gl.glBindTexture(GL10.GL_TEXTURE_2D, textureName);

    gl.glTexParameterf(GL10.GL_TEXTURE_2D, GL10.GL_TEXTURE_MIN_FILTER, GL10.GL_NEAREST);
    gl.glTexParameterf(GL10.GL_TEXTURE_2D, GL10.GL_TEXTURE_MAG_FILTER, GL10.GL_LINEAR);

    gl.glTexParameterf(GL10.GL_TEXTURE_2D, GL10.GL_TEXTURE_WRAP_S, GL10.GL_CLAMP_TO_EDGE);
    gl.glTexParameterf(GL10.GL_TEXTURE_2D, GL10.GL_TEXTURE_WRAP_T, GL10.GL_CLAMP_TO_EDGE);

    gl.glTexEnvf(GL10.GL_TEXTURE_ENV, GL10.GL_TEXTURE_ENV_MODE, GL10.GL_REPLACE);

    final int internalFormat = GL10.GL_RGBA;
    final int type = GL10.GL_UNSIGNED_BYTE;
    gl.glTexImage2D(GL11.GL_TEXTURE_2D, 0, internalFormat, mCameraPreviewSprite.textureWidth, mCameraPreviewSprite.textureHeight, 0, internalFormat, type, (ByteBuffer) null);

    mCameraPreviewSprite.setTextureName(textureName);
}

以下是错误消息：

E/MALI(22964): gles_state_set_error_internal:57: GLES error code:0x500

然而，当我删除glHint时，会发生以下gl调用的其他类似错误，是由gl es版本引起的吗？谢谢！

以下是活动中onCreate()函数中的代码：

if(supportsEs2)
   mGlSurfaceView.setEGLContextClientVersion(2);
mGlSurfaceView.setRenderer(mRenderer); 
mGlSurfaceView.setRenderMode(GLSurfaceView.RENDERMODE_WHEN_DIRTY); 
mGlSurfaceView.setDebugFlags(GLSurfaceView.DEBUG_CHECK_GL_ERROR); 
setContentView(mGlSurfaceView);

GL版本的GLsurfaceview
