android添加3个虚拟按键音

在PhoneWindowManager.java的interceptKeyBeforeQueueing方法中添加

if (keyCode == KeyEvent.KEYCODE_HOME

|| keyCode == KeyEvent.KEYCODE_BACK || KeyEvent.KEYCODE_MENU) {
performVirtualKeyClickSound();

}

private void performVirtualKeyClickSound() {
       AudioManager audioManager = (AudioManager) mContext
               .getSystemService(Context.AUDIO_SERVICE);
       if (audioManager != null) {
           audioManager.playSoundEffect(AudioManager.FX_KEY_CLICK);
       } else {
           Log.w(TAG, "performVirtualKeyClickSound");
       }
   }

在PhoneWindow.java中注视掉

if (playSoundEffect && ! SystemProperties.getBoolean("persist.sys.ts18.sp025",false)) {这个地方在有的场景中会播放menu音量，要屏蔽掉。
                AudioManager audioManager = (AudioManager) getContext().getSystemService(
                        Context.AUDIO_SERVICE);
                if (audioManager != null) {
                    audioManager.playSoundEffect(AudioManager.FX_KEY_CLICK);
                } else {
                    Log.w(TAG, "Couldn't get audio manager");
                }
            }
