安卓工作室-如何避免VideoView溢出其(视图)容器

Question

我在一个水平的Linearlayout中有3个VideoViews，我希望每个都播放不同的视频，每个视频将只显示其原始视频的一部分(因此，每个视频都包含在Linearlayout中，将显示的内容从150dp限制为150dp(。问题是视频重叠。作为一个例子，我展示了我只填充VideoView Central的代码，但它侵犯了其他VideoView的区域，我已经尝试了一切，但我无法使它们不相互侵犯。知道怎么修吗。注意：VideoView必须大于其150x150dp LinearLayout容器。

在该图中，我显示实际错误和需要的正确结果

嘿，我偶然发现了类似的东西，我发现的问题是VideoView原生扩展了surfaceView。所以我选择不尝试用textureView播放视频，这是我使用的库，它帮助我处理了这个错误。可扩展视频视图

如果您在实施此库时遇到任何其他问题，请告诉我
