如何使用GLSurfaceView.Renderer打开摄像头

<uses-permission android:name="android.permission.CAMERA" />

<android.opengl.GLSurfaceView
    android:id="@+id/glsurfaceview"
    android:layout_width="match_parent"
    android:layout_height="match_parent" />

public class MyRenderer implements GLSurfaceView.Renderer {
    private Camera camera;

    @Override
    public void onSurfaceCreated(GL10 gl, EGLConfig config) {
        // 初始化摄像头
        camera = Camera.open();
        // 设置摄像头预览显示的Surface
        try {
            camera.setPreviewDisplay(holder);
        } catch (IOException e) {
            e.printStackTrace();
        }
        // 开始预览
        camera.startPreview();
    }

    @Override
    public void onSurfaceChanged(GL10 gl, int width, int height) {
        // 设置视口大小
        GLES20.glViewport(0, 0, width, height);
    }

    @Override
    public void onDrawFrame(GL10 gl) {
        // 渲染图形
        // ...
    }
}

GLSurfaceView glSurfaceView = findViewById(R.id.glsurfaceview);
glSurfaceView.setEGLContextClientVersion(2); // 设置OpenGL ES版本
glSurfaceView.setRenderer(new MyRenderer());
