Judging by the code here :(which you can use actually), you can use the method getSupportedPreviewSizes() and see what are the supported resolutions, 1024x768 could easily be the highest one available for this preview and as you found out, it is really the highest supported. 从这里的代码判断（您可以实际使用），您可以使用方法getSupportedPreviewSizes()并查看支持的分辨率， 1024x768可能是该预览版可用的最高分辨率，并且您发现它确实是最高支持。

So those are the supported resolutions, there's no way you can get higher than the supported. 因此，这些是受支持的分辨率，您无法获得比受支持的更高的分辨率。 You must find a workaround for this, like to put the preview in the center and surrond it with black frame or something like that. 您必须为此找到一种解决方法，例如将预览放在中间并用黑框或类似的东西替代。
