Android Studio - 如何避免 VideoView 溢出其（视图）容器？

Question

我在水平线性布局中有 3 个视频视图，我希望每个视频都播放不同的视频，每个视频只会显示其原始视频的一部分（因此每个视频都包含在一个线性布局中，限制了应该从 150dp 显示的内容到 150dp）。 问题是视频重叠。作为一个例子，我展示了我只填充 VideoView Central 但它侵入了其他 VideoViews 的区域的代码，我已经尝试了所有方法，但我不能让它们不互相侵入。任何想法如何解决它。 注意： VideoView 必须大于其 150x150dp LinearLayout 容器。

Answer 1

嘿，我偶然发现了类似的东西，我发现的问题是 VideoView 本身扩展了 surfaceView。所以我选择尝试使用 textureView 播放视频，这是我使用的库，它帮助我处理错误。ScalableVideoView

如果您在实施此库时遇到任何其他问题，请告诉我
