如何在Android Camera API中修复拉伸图像？

Question

我正在获得图像的拉伸预览我想将它固定为肖像，即使在相机旋转后它也固定为肖像。我使用以下代码。

client.GetAsync(new Uri("http://example.com/?id=123%34"));
// also returns GET http://example.com?id=1234 (before it reaches the server)
// I need the server to see http://example.com?id=123%34 before it reaches
// the server so it can convert the value 4 on the server side.

设置

private TextureView mTextureView;
private TextureView.SurfaceTextureListener mSurfaceTextureListener = new TextureView.SurfaceTextureListener() {
        @Override
        public void onSurfaceTextureAvailable(SurfaceTexture surface, int width, int height) {
            setupCamera(width, height);
            connectCamera();
        }

        @Override
        public void onSurfaceTextureSizeChanged(SurfaceTexture surface, int width, int height) {

        }

        @Override
        public boolean onSurfaceTextureDestroyed(SurfaceTexture surface) {
            return false;
        }

        @Override
        public void onSurfaceTextureUpdated(SurfaceTexture surface) {

        }
    };
