android - 如何在 Android 中为 GLSurfaceView 设置动画

Question

我读过这个。但似乎 GLSurfaceView 可以滚动scrollBy，所以是否可以在 ApiDemos/Rotate3DAnimation 或 GLSurfaceView 上应用 3D 过渡（翻转）或类似的东西？

ApiDemos/Rotate3DAnimation的部分源码如下：

@Override
protected void applyTransformation(float interpolatedTime, Transformation t) {
    final float fromDegrees = mFromDegrees;
    float degrees = fromDegrees + ((mToDegrees - fromDegrees) * interpolatedTime);

    final float centerX = mCenterX;
    final float centerY = mCenterY;
    final Camera camera = mCamera;

    final Matrix matrix = t.getMatrix();

    camera.save();
    if (mReverse) {
        camera.translate(0.0f, 0.0f, mDepthZ * interpolatedTime);
    } else {
        camera.translate(0.0f, 0.0f, mDepthZ * (1.0f - interpolatedTime));
    }
    camera.rotateY(degrees);
    camera.getMatrix(matrix);
    camera.restore();

    matrix.preTranslate(-centerX, -centerY);
    matrix.postTranslate(centerX, centerY);
}
