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<Bean> list; private Context context; public ArrayList<Bean> getList() { return list; } public void setList(ArrayList<Bean> list) { if(list!=null){ this.list = list; }else{ list=new ArrayList<Bean>(); } } public AdapterListView(Context context,ArrayList<Bean> list){ this.setList(list); this.context=context; } @Override public int getCount() { // TODO Auto-generated method stub return list.size(); } @Override public Bean getItem(int position) { // TODO Auto-generated method stub return list.get(position); } @Override public long getItemId(int position) { // TODO Auto-generated method stub return position; } @Override public View getView(int position, View converView, ViewGroup viewGrop) { // TODO Auto-generated method stub ViewHolder 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; } @Override public boolean isItemViewTypePinned(int viewType) { // TODO Auto-generated method stub return viewType == Bean.SECTION;//0是标题,1是内容 } @Override public int getViewTypeCount() { return 2;//2种view的类型 baseAdapter中得方法 } @Override public int getItemViewType(int position) { return ((Bean)getItem(position)).type; } public void refresh(ArrayList<Bean> 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; } @Override public void onClick(View v) { // TODO Auto-generated method stub if(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(); } } }
