Android WebView 使用 javascript 播放音频 [英] Android WebView playing audio with javascript

问题描述

我正在尝试非常快速地将带有播放声音(使用 soundmanager2)的 html 应用程序移植到使用 WebView 的本机 Android 应用程序.根据我的研究，我没有看到任何证据表明声音(例如 mp3)可以通过 javascript 或使用 WebView 的任何其他方法播放.

I'm trying to very quickly port over an html application with plays sound (with soundmanager2) to a native android app using WebView. From my research, I haven't seen any evidence that sound, such as mp3s, can be played via javascript or any other methods using WebView.

我现在的目标是快速移植 html 应用，然后最终在不使用 WebView 的情况下创建一个真正的原生应用.

My goal now is to quickly port over the html app and then eventually create a truely native application without using WebViews.

如果有人能够使用 WebViews 和 Javascript 成功实现播放音频，或者目前无法实现，请告诉我.

Please let me know if anyone has been able to successfully implement playing audio using WebViews and Javascript or if this is just not possible at this time.

谢谢.

推荐答案

试试这个:

if(cm.message().contains("play sound")) {
    //String[] temp = cm.message().split("#");
    AudioManager audiomanager= (AudioManager) getSystemService(AUDIO_SERVICE);
    float actualvolume = (float) audiomanager.getStreamVolume (AudioManager.STREAM_MUSIC);
    float maxVolume= (float) audiomanager.getStreamMaxVolume(AudioManager.STREAM_MUSIC);
    float volume = actualvolume/maxVolume;

    if (loaded) {
        soundPool.play(soundID, volume, volume, 1, 54, 1f);
        Log.e("Test", "Played sound");
    }
} else if(cm.message().contains("stop sound")) {
    soundPool.stop(1);
    Log.e("Test","stoped");
}

myWebView.loadUrl("file:///android_asset/timer.html");
soundID = soundPool.load(this, R.raw.sound1,1);
