Question

android中VideoView和TextureView、Suraceview有什么区别？

我什么时候使用它们？

Answer 1

抱歉回答晚了，只是偶然发现了这个，但是 TL;DR 答案是这样的:

VideoView -> VideoView 扩展了 SurfaceView，本质上只是 SurfaceView + MediaPlayer。为了您的方便，表面和 MediaPlayer 等的拆卸由小部件负责。

SurfaceView-> 根据 Android 开发人员的说法:

Provides a dedicated drawing surface embedded inside of a view hierarchy. You can control the format of this surface and, if you like, its size; the SurfaceView takes care of placing the surface at the correct location on the screen

The surface is Z ordered so that it is behind the window holding its SurfaceView; the SurfaceView punches a hole in its window to allow its surface to be displayed

这意味着它从 View 层次结构中获取信息来创建连接到 GPU 的专用绘图区域。其缺点是没有动画和过渡等花哨的 View 内容。但性能更高

TextureView -> 来自 Android 开发者:

Unlike SurfaceView, TextureView does not create a separate window but behaves as a regular View. This key difference allows a TextureView to be moved, transformed, animated, etc

你知道了，TextureView 的缺点意味着，由于它是 View 层次结构的一部分，它会在 View 传递期间自行重绘，从而消耗更多资源，但你将具有动画、过渡、alpha 等
