将扬声器中的音频切换到耳扬声器，将扬声器切换到扬声器 [英] Toggle audio in speaker to ear-speaker and ear-speaker to speaker

问题描述

我们在Xamarin.Forms.Android项目中使用了第三方音频/视频SDK.现在的问题是，默认情况下，音频进入扬声器模式，而不是入耳式.我曾尝试在Internet上搜索解决方案，但发现以下代码可以设置耳塞和扬声器的音频.实施以下代码后，扬声器中的音频关闭但无法通过耳塞收听，如果我设置SpeakerphoneOn = true，则可以通过扬声器收听，但是如果我将SpeakerphoneOn = false设置为音频，那么我将无法通过耳塞列出.

另外，即使更改为InCall或任何其他模式，模式"值始终始终为"InCommunication".

我在Xamarin项目中也设置了以下权限. 允许:

var audioManager = (Android.Media.AudioManager)Android.App.Application.Context.GetSystemService(Android.Content.Context.AudioService);

audioManager.SpeakerphoneOn = !audioManager.SpeakerphoneOn;

解决方案

检查模式为耳讲时，音量值是否为0.两种模式的音量分别控制.

var audioManager = (Android.Media.AudioManager)Android.App.Application.Context.GetSystemService(Android.Content.Context.AudioService);
audioManager.Mode = Mode.InCommunication;
audioManager.SpeakerphoneOn = false;
audioManager.SetStreamVolume(Stream.Music, audioManager.GetStreamMaxVolume(Stream.Music), VolumeNotificationFlags.ShowUi);

We are using third party Audio/Video SDK in our Xamarin.Forms.Android project. Now problem is that by default audio comes in speaker mode, instead of ear-speaker. I was tried to search solution in internet and found below code to set audio in ear-speaker and speaker. After implement below code audio off in speaker but not able to listen via ear-speaker, if I set SpeakerphoneOn=true then I can listen via Speakerphone but if I set SpeakerphoneOn=false then I can't list via ear-speaker.

Additional point, Mode value is always comes "InCommunication" even after change to InCall or any other mode.

I have set below permission too in my Xamarin project. Permission:

var audioManager = (Android.Media.AudioManager)Android.App.Application.Context.GetSystemService(Android.Content.Context.AudioService);

audioManager.SpeakerphoneOn = !audioManager.SpeakerphoneOn;

解决方案

Check when mode is ear-speaker , the volume value whether is 0 .The volume of their two modes is controlled separately.

var audioManager = (Android.Media.AudioManager)Android.App.Application.Context.GetSystemService(Android.Content.Context.AudioService);
audioManager.Mode = Mode.InCommunication;
audioManager.SpeakerphoneOn = false;
audioManager.SetStreamVolume(Stream.Music, audioManager.GetStreamMaxVolume(Stream.Music), VolumeNotificationFlags.ShowUi);
