GLConsumer已附加到新SurfaceTexture的上下文中 [英] GLConsumer is already attached to a context for new SurfaceTexture

问题描述

在手动创建时，SurfaceTexture是否默认连接到GLContext?如果可以，怎么办?

Is SurfaceTexture attached to GLContext by default when created manually? If so, how?

这里是一个示例，我正在尝试创建自己的SurfaceTexture并将其设置为TextureView:

Here is an example, I'm trying to create my own SurfaceTexture and set it to TextureView:

public class MainActivity extends AppCompatActivity {
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        TextView textView = (TextView) findViewById(R.id.version);
        TextureView textureView = (TextureView) findViewById(R.id.texture);

        int[] arr = new int[1];
        GLES20.glGenTextures(1, arr, 0);
        int texName = arr[1];

        SurfaceTexture surfaceTexture = new SurfaceTexture(texName);
        textureView.setSurfaceTexture(surfaceTexture);
    }
}

我不断得到:

E/GLConsumer:[unnamed-29058-0] attachToContext:GLConsumer已经存在 附加到上下文

E/GLConsumer: [unnamed-29058-0] attachToContext: GLConsumer is already attached to a context

在新创建的SurfaceTexture对象上调用detachFromGLContext可以解决问题，但是这很令人困惑，因为我可以确认在这种情况下从未调用过attachToGLContext.

Calling detachFromGLContext on newly created SurfaceTexture object solves the problem, but that's rather confusing as I can confirm that attachToGLContext is never called in this scenario.

P.S.我知道默认情况下TextureView具有它自己的SurfaceTexture.在这种情况下，我必须使用从SurfaceTexture扩展的自己的实现.

P.S. I know that TextureView has it's own SurfaceTexture by default. In this scenario I have to use own implementation that extends from SurfaceTexture.

推荐答案

在Android O中，有一个

In Android O there is a new constructor which doesn't attach immediately. Sounds like that's what you want. As your self-answer says, the previous constructors automatically attach to the current thread's GL context.
