网上开源项目：https://github.com/beworker/pinned-section-listview，该项目用的是ArrayAdapter()..不太适合我，稍作修改，仿的微信界面
PinnedSectionListView修改了一行代码，不然会报错，代码如下
void createPinnedShadow(int position) {}》》
if (layoutParams == null) { //layoutParams = (LayoutParams) generateDefaultLayoutParams();layoutParams = new LayoutParams(LayoutParams.MATCH_PARENT, LayoutParams.WRAP_CONTENT); pinnedView.setLayoutParams(layoutParams);}效果图：
具体代码AdapterListView：
package pinneactivity.example.ui;import java.util.ArrayList;import pinneactivity.example.ui.PinnedSectionListView.PinnedSectionListAdapter;import android.content.Context;import android.view.LayoutInflater;import android.view.View;import android.view.ViewGroup;import android.widget.BaseAdapter;import android.widget.ImageView;import android.widget.TextView;/* * * This is company of adapter * * @author YangWenlong */public class AdapterListView extends BaseAdapter implements PinnedSectionListAdapter{private ArrayList list;private Context context;public ArrayList getList() {return list;}public void setList(ArrayList list) {if(list!=null){this.list = list;}else{list=new ArrayList();}}public AdapterListView(Context context,ArrayList list){this.setList(list);this.context=context;}@Overridepublic int getCount() {// TODO Auto-generated method stubreturn list.size();}@Overridepublic Bean getItem(int position) {// TODO Auto-generated method stubreturn list.get(position);}@Overridepublic long getItemId(int position) {// TODO Auto-generated method stubreturn position;}@Overridepublic View getView(int position, View converView, ViewGroup viewGrop) {// TODO Auto-generated method stubViewHolder vh=null;if(converView==null){vh=new ViewHolder();converView=LayoutInflater.from(context).inflate(R.layout.item, null);vh.company_item=(TextView)converView.findViewById(R.id.title);vh.image=(ImageView)converView.findViewById(R.id.imageView1);converView.setTag(vh);}else{vh=(ViewHolder) converView.getTag();}Bean bean=getItem(position);vh.company_item.setText(bean.text);if (bean.type == Bean.SECTION) {vh.company_item.setBackgroundResource(R.drawable.bao_headview_bg);vh.image.setVisibility(View.GONE);}else{vh.company_item.setBackgroundResource(R.drawable.details_layout_bg);vh.image.setVisibility(View.VISIBLE);}return converView;}@Overridepublic boolean isItemViewTypePinned(int viewType) {// TODO Auto-generated method stubreturn viewType == Bean.SECTION;//0是标题，1是内容}@Overridepublic int getViewTypeCount() {return 2;//2种view的类型 baseAdapter中得方法}@Overridepublic int getItemViewType(int position) {return ((Bean)getItem(position)).type;}public void refresh(ArrayList arr){ setList(arr); notifyDataSetChanged(); }} HeadView:
package pinneactivity.example.ui;import android.app.Activity;import android.view.View;import android.view.View.OnClickListener;import android.widget.LinearLayout;import android.widget.Toast;/* * Fail view * * @author YangWenlong */public class HeadView implements OnClickListener{private View view = null;private Activity activity;private LinearLayout newFriends;private LinearLayout grop;private LinearLayout tag;private LinearLayout publicNumber;private static HeadView headView = null;public static HeadView getInstance(Activity activity) {headView = new HeadView(activity);return headView;}public HeadView(Activity activity) {view=activity.getLayoutInflater().inflate(R.layout.item_head, null);this.activity=activity;}public HeadView initialization(){ newFriends=(LinearLayout)view.findViewById(R.id.layout_new); grop=(LinearLayout)view.findViewById(R.id.layout_group); tag=(LinearLayout)view.findViewById(R.id.layout_tag); publicNumber=(LinearLayout)view.findViewById(R.id.layout_public); newFriends.setOnClickListener(this); grop.setOnClickListener(this); tag.setOnClickListener(this); publicNumber.setOnClickListener(this);return headView;}public View getView(){return view;}@Overridepublic void onClick(View v) {// TODO Auto-generated method stubif(v==newFriends){Toast.makeText(activity, "新朋友", Toast.LENGTH_SHORT).show();}else if(v==grop){Toast.makeText(activity, "群聊", Toast.LENGTH_SHORT).show();}else if(v==tag){Toast.makeText(activity, "标签", Toast.LENGTH_SHORT).show();}else if(v==publicNumber){Toast.makeText(activity, "公众号", Toast.LENGTH_SHORT).show();}}}项目下载： http://download.csdn.net/detail/anddroid_lanyan/8252891
