通过程序获取android系统手机的铃声和音量。同样，设置铃声和音量的方法也很简单！

audiomanager maudiomanager = (audiomanager) getsystemservice(context.audio_service);//通话音量int max = maudiomanager.getstreammaxvolume( audiomanager.stream_voice_call );int current = maudiomanager.getstreamvolume( audiomanager.stream_voice_call );log.d(“vioce_call”, “max : ” + max + ” current : ” + current);//系统音量max = maudiomanager.getstreammaxvolume( audiomanager.stream_system );current = maudiomanager.getstreamvolume( audiomanager.stream_system );log.d(“system”, “max : ” + max + ” current : ” + current);//铃声音量max = maudiomanager.getstreammaxvolume( audiomanager.stream_ring );current = maudiomanager.getstreamvolume( audiomanager.stream_ring );log.d(“ring”, “max : ” + max + ” current : ” + current);//音乐音量max = maudiomanager.getstreammaxvolume( audiomanager.stream_music );current = maudiomanager.getstreamvolume( audiomanager.stream_music );log.d(“music”, “max : ” + max + ” current : ” + current);//提示声音音量max = maudiomanager.getstreammaxvolume( audiomanager.stream_alarm );current = maudiomanager.getstreamvolume( audiomanager.stream_alarm );log.d(“alarm”, “max : ” + max + ” current : ” + current);

ps：
游戏过程中 只允许调整多媒体音量，而不允许调整通话音量。

setvolumecontrolstream(audiomanager.stream_music);
