播放视频时禁用Android的VideoView requestAudioFocus?

本文介绍了播放视频时禁用Android的VideoView requestAudioFocus?的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！ 问题描述

我正在构建一个记录和播放视频的应用程序.我希望这样做不会影响背景音乐的播放，即，如果我开始播放视频，我不想暂停其他应用程序的音频.但是，在Lollipop上，调用私有方法VideoView.openVideo()时，Android的VideoView类会自动请求音频焦点:

I'm building an app that records and plays back video. I would like to do so without affecting background music playback, i.e. if I begin playing a video, I do not want to pause other apps' audio. However, on Lollipop, Android's VideoView class automatically requests audio focus when the private method VideoView.openVideo() is called:

AudioManager am = (AudioManager) super.getSystemService(name); am.requestAudioFocus(null, AudioManager.STREAM_MUSIC, AudioManager.AUDIOFOCUS_GAIN);

有关如何解决此问题的任何建议?

Any suggestions on how to get around this?

推荐答案

从Android SDK 26开始，您可能要使用VideoView和

Starting with Android SDK 26 you may want to use VideoView and

if(Build.VERSION.SDK_INT >= Build.Version_CODES.O){ //set this BEFORE start playback videoView.setAudioFocusRequest(AudioManager.AUDIOFOCUS_NONE) }

对于较旧的版本，此处描述了一种解决方法: stackoverflow/a/31569930/993439

For older version, there's a workaround described here: stackoverflow/a/31569930/993439

基本上，复制VideoView的源代码并取消注释以下行

Basically, copy source code of VideoView and uncomment following lines

AudioManager am = (AudioManager) getContext().getSystemService(Context.AUDIO_SERVICE); am.requestAudioFocus(null, AudioManager.STREAM_MUSIC, AudioManager.AUDIOFOCUS_GAIN);
