SurfaceView高度+宽度被忽略 [英] SurfaceView height + width gets ignored

问题描述

下面的脚本作品完美无瑕，但改变我surfaceview从纵向到横向后，我的录像机的规模将得到f'd。试了几个选项，如 setFixedSize（）， setSizeFromLayout（）和消除一切涉及我宽+高从我surfaceview。没有人知道什么是错与下面的code？ 还是因为别人有同样的问题，在过去？

解决方案

同样在这里的问题：

我相信这个问题是Vitamio库，因为我已经经历过类似的问题在与Vitamio SDK处理。调整大小，我没有工作，当使用 SurfaceView 并调用 setLayoutParams（ViewGroup.LayoutParams PARAMS）。下面code工作正常使用标准的Andr​​oid媒体框架，但在导入vitamio包打破它。

RelativeLayout.LayoutParams video_VIEWLAYOUT =（RelativeLayout.LayoutParams）videoView.getLayoutParams（）;
video_VIEWLAYOUT.width =屏幕宽度;
video_VIEWLAYOUT.height =（INT）（（（浮点）videoHeight /（浮点）videoWidth）*（浮点）屏幕宽度）;
videoView.setLayoutParams（video_VIEWLAYOUT）;

我的建议是尝试使用，而不是 io.vov.vitamio.widget.VideoView A android.view.SurfaceView 。

The following script works flawless, but the size of my videoplayer will get f'd after changing my surfaceview from portrait to landscape. Tried several options like setFixedSize(), setSizeFromLayout() and removing everything which involves my width + height from my surfaceview. Does anyone knows whats wrong with the code below? Or did someone have the same problem in the past?

解决方案

Same problem here:

I believe the problem is the Vitamio library as I have experienced a similar problem when dealing with the Vitamio SDK. Resizing didn't work for me, when using a SurfaceView and invoking setLayoutParams(ViewGroup.LayoutParams params). The below code works fine using the standard Android media-framework, but importing the vitamio packages breaks it.

RelativeLayout.LayoutParams video_VIEWLAYOUT = (RelativeLayout.LayoutParams) videoView.getLayoutParams();
video_VIEWLAYOUT.width = screenWidth;
video_VIEWLAYOUT.height = (int) (((float)videoHeight / (float)videoWidth) *(float)screenWidth);
videoView.setLayoutParams(video_VIEWLAYOUT);

My recommendation would be to try using the io.vov.vitamio.widget.VideoView instead of a android.view.SurfaceView.

这篇关于SurfaceView高度+宽度被忽略的文章就介绍到这了，希望我们推荐的答案对大家有所帮助，也希望大家多多支持IT屋！
