Android网络收音机--使用Vitamio解码（一）

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

public void setOnMenuListOnItemClickListener(OnMenuListOnItemClickListener listener) {mListener = listener;}public interface OnMenuListOnItemClickListener {public void onSelectItem(int groupPosition, int childPosition);}@Overridepublic boolean onChildClick(ExpandableListView parent, View v,int groupPosition, int childPosition, long id) {// TODO Auto-generated method stubif (mListener != null) {mListener.onSelectItem(groupPosition, childPosition);}return false;}在MainActivity.java类中设置监听器，和设置Handler与Service通信

/*** 选择对应的Item*/@Overridepublic void onSelectItem(int groupPosition, int childPosition) {// TODO Auto-generated method stubRadioChannelData 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
