在Android应用中使Webview静音 [英] Mute webview in android apps

问题描述

我正在构建一个包含一些WebViews的应用.

I'm building an app that includes some WebViews.

我想忽略其中一个(不是整个应用程序或设备，只是那个特定的WebView)，但是对此问题没有确定的答案. 有谁知道如何在Android中静音WebView声音?

I want to mute one of them (not the whole app or device just that specific WebView) I searched but there's no certain answer to this question. Is there anyone knows how to mute a WebView sound in Android?

推荐答案

您不能仅静音WebViews卷，但是可以在显示WebView时静音整个系统卷.喜欢 :
当您显示特定的WebView时，请使用以下方法:

You can't mute only WebViews volume, but you can mute the whole system volume when you are showing the WebView. Like :
When you are showing that particular WebView use the below method :

public static void mute(Context context) {
    AudioManager mAudioManager = (AudioManager) context.getSystemService(Context.AUDIO_SERVICE);
    int mute_volume = 0;
    mAudioManager.setStreamVolume(AudioManager.STREAM_MUSIC, mute_volume, 0);
}

当未显示webView时，请设置最大音量，例如:

And when the webView is not shown set max volume Like :

public static void unmute(Context context) {
    AudioManager mAudioManager = (AudioManager) context.getSystemService(Context.AUDIO_SERVICE);
    int unmute_volume = mAudioManager.getStreamMaxVolume(AudioManager.STREAM_MUSIC);
    mAudioManager.setStreamVolume(AudioManager.STREAM_MUSIC, unmute_volume, 0);
}

如果您不想设置完整音量，则可以通过以下方式获取当前系统音量

If you don't want to set full volume you can get current system volume by

mAudioManager.getStreamVolume(AudioManager.STREAM_MUSIC);

并将其保存在本地，然后在退出Webview时再次将其重新设置.

and save it locally and set it back again when you exit the Webview.
