一.主要实现功能：
1.跑马灯文字设计
2.欢迎界面跳转
3.下拉刷新
4.方向传感器设计使用（网上的资源，此处用来测试）
5.本地收藏
二.代码实现简要：
1.设置权限：
<uses-permission android:name="android.permission.MOUNT_UNMOUNT_FILESYSTEMS" />
<uses-permission android:name="android.permission.RECORD_AUDIO" />
<uses-permission android:name="android.permission.INTERNET" />
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
<uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE" />
<uses-permission android:name="android.permission.VIBRATE" />
<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" />
<uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION" />
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />
<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" />
<uses-permission android:name="android.permission.READ_PHONE_STATE" />
<uses-permission android:name="android.permission.CHANGE_WIFI_STATE" />
<uses-permission android:name="android.permission.ACCESS_WIFI_STATE" />
<uses-permission android:name="android.permission.CHANGE_CONFIGURATION" />
<uses-permission android:name="android.permission.WAKE_LOCK" />
<uses-permission android:name="android.permission.WRITE_SETTINGS" />2."首页博客" 实现类代码参考：

}3.BlogAdapter,适配博客信息：
public class BlogsAdapter extends BaseAdapter{
private Context context;
private LayoutInflater inflater;
private ArrayList<Blogs> blogs=new ArrayList<Blogs>();
private RequestQueue mQueue;
private ImageLoader mImageLoader;
private ImageListener listener;
public BlogsAdapter(Context context,ArrayList<Blogs> Blogs) {
this.context=context;
this.blogs=Blogs;
inflater = LayoutInflater.from(context);
mQueue = Volley.newRequestQueue(context);
mImageLoader = new ImageLoader(mQueue, new BitmapCache());
}
@Override
public int getCount() {
// TODO Auto-generated method stub
return blogs.size();
}
@Override
public Object getItem(int position) {
// TODO Auto-generated method stub
return position;
}
@Override
public long getItemId(int position) {
// TODO Auto-generated method stub
return position;
}
@Override
public View getView(final int position, View convertView, ViewGroup parent) {
// TODO Auto-generated method stub
ViewHolder hodler;
if (convertView==null) {
//inflater=(LayoutInflater) context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
convertView=inflater.inflate(R.layout.item_blogs, null);
hodler=new ViewHolder();
hodler.tv_Title=(TextView) convertView.findViewById(R.id.tv_newTitle);
hodler.tv_name=(TextView) convertView.findViewById(R.id.tv_name);
hodler.tv_uri=(TextView) convertView.findViewById(R.id.tv_uri);
hodler.iv_avatar=(ImageView) convertView.findViewById(R.id.iv_avatar);
hodler.tv_diggs=(TextView) convertView.findViewById(R.id.tv_diggs);
hodler.tv_views=(TextView) convertView.findViewById(R.id.tv_views);
hodler.tv_comments=(TextView) convertView.findViewById(R.id.tv_comments);
hodler.tv_summary=(TextView) convertView.findViewById(R.id.tv_summary);
hodler.tv_updated=(TextView) convertView.findViewById(R.id.tv_updated);
hodler.tv_postid=(TextView) convertView.findViewById(R.id.tv_blogID);
convertView.setTag(hodler);
}else {
hodler=(ViewHolder) convertView.getTag();
}
hodler.iv_avatar.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View v) {
// TODO Auto-generated method stub
Toast.makeText(context, "准备添加收藏！", Toast.LENGTH_SHORT).show();
}
});
String Pub_Date = blogs.get(position).getPublished().substring(0,10);
String Pub_Time = blogs.get(position).getPublished().substring(11,19);
hodler.tv_Title.setText(blogs.get(position).getTitle());
hodler.tv_summary.setText(" "+blogs.get(position).getSummary());
hodler.tv_name.setText("博主："+blogs.get(position).getAuthorName());
hodler.tv_uri.setText("主页："+blogs.get(position).getAuthorUri());
hodler.tv_diggs.setText(String.valueOf(blogs.get(position).getDiggs()));
hodler.tv_comments.setText(String.valueOf(blogs.get(position).getComments()));
hodler.tv_views.setText(String.valueOf(blogs.get(position).getViews()));
hodler.tv_postid.setText(String.valueOf(blogs.get(position).getId()));
hodler.tv_updated.setText("时间："+Pub_Date+"\t\t"+Pub_Time);
String imgAvaterUrl=blogs.get(position).getAuthorAvater();
listener = ImageLoader.getImageListener(hodler.iv_avatar, R.drawable.icon3, R.drawable.icon3);
//根据博主头像存在与否进行 图片加载判断
if (imgAvaterUrl==null ||imgAvaterUrl.equals("")) {
hodler.iv_avatar.setImageResource(R.drawable.icon3);;
}else {
mImageLoader.get(imgAvaterUrl, listener);
}
return convertView;
}
class ViewHolder{
TextView tv_Title,tv_published,
tv_sourceName,tv_summary,tv_views,tv_comments,tv_diggs,tv_postid,
tv_name,tv_uri,tv_updated;
ImageView iv_avatar;
}
}4.博客信息解析类代码参考：
/**
* 推荐博客的Pull解析方法
* @param inputStream
* @return
*/
public static ArrayList<Blogs> ParseBlogs(InputStream inputStream) {
ArrayList<Blogs> blogList = null;
Blogs blog = null;
boolean isEntry=false;
XmlPullParser parser=Xml.newPullParser();
try {
parser.setInput(inputStream, "UTF-8");
int eventType=parser.getEventType();
while(eventType!=XmlPullParser.END_DOCUMENT){
switch (eventType) {
case XmlPullParser.START_DOCUMENT:
blogList=new ArrayList<Blogs>();
break;
case XmlPullParser.START_TAG:
if(parser.getName().equals("entry")){
isEntry=true;
blog=new Blogs();
}else if(parser.getName().equals("id") && isEntry){
blog.setId(parser.nextText());
}else if(parser.getName().equals("title") && isEntry){
blog.setTitle(parser.nextText());
}else if(parser.getName().equals("summary") && isEntry){
blog.setSummary(parser.nextText());
}else if(parser.getName().equals("published") && isEntry){
blog.setPublished(parser.nextText());
}else if(parser.getName().equals("updated") && isEntry){
String[] t=parser.nextText().split("T");
blog.setUpdated(t[0]+t[1]);
}else if(parser.getName().equals("views") && isEntry){
blog.setViews(Integer.parseInt(parser.nextText()));
}else if(parser.getName().equals("comments") && isEntry){
blog.setComments(Integer.parseInt(parser.nextText()));
}else if(parser.getName().equals("diggs") && isEntry){
blog.setDiggs(Integer.parseInt(parser.nextText()));
}else if(parser.getName().equals("name") && isEntry){
blog.setAuthorName(parser.nextText());
}
else if(parser.getName().equals("uri") && isEntry){
blog.setAuthorUri(parser.nextText());
}
else if(parser.getName().equals("avatar") && isEntry){
blog.setAuthorAvater(parser.nextText());
}
break;
case XmlPullParser.END_TAG:
if(parser.getName().equals("entry") && blog!=null){
blogList.add(blog);
blog=null;
}
break;
default:
break;
}
parser.next();
eventType=parser.getEventType();
}
inputStream.close();
} catch (XmlPullParserException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (NumberFormatException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
return blogList;
}5.提示：毕竟项目所涉及的代码太多，相信拥有Android基础的你一定看的懂，再次不做赘述，希望能给你带来帮助。
三.项目运行截图
1.微博首页加载及其显示，可进行下拉刷新
2.搜索博主页面，进行列表显示
3.下拉刷新加载博主的博文信息
4.方向传感器是的使用
5.收藏书签
6.项目退出
四.源代码提供
