前面讲到Vitamio可以支持一些流媒体,在这里就用Vitamio来播放网络上的一些流媒体,如:mms、rtsp、http,参考前辈的一些文章来写一个网络收音机程序,对于界面的要求不高,要求实现一些实用的功能
程序目录结构
初期界面,左边是用开源项目SlidingMenu,不清楚的可以参考:Android开源项目SlidingMenu的学习笔记
电台信息是通过XML来保存channel.xml,这里只添加一部分,更详细的可以参考文章最后的链接,自行添加

/** * 选择对应的Item */ @Override public void onSelectItem(int groupPosition, int childPosition) { // TODO Auto-generated method stub RadioChannelData channelData = NetRadioApp.finalChanneldata.get( groupPosition).get(childPosition); mName.setText(channelData.getChannelName()); for (int i = 0; i < mUpdateHandler.size(); i++) { Handler h = mUpdateHandler.get(i); Message msg = h.obtainMessage(); msg.what = GlobalConstants.SELECT_ITEM; Bundle data = new Bundle(); data.putInt("groupPosition", groupPosition); data.putInt("childPosition", childPosition); msg.setData(data); h.sendMessage(msg); } } public static void addUpdateHandler(Handler handler) { mUpdateHandler.add(handler); } public static void removeUpdateHandler(Handler handler) { mUpdateHandler.remove(handler); }在Service中处理播放PlayService.java
