Android----PinnedSectionListView

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) {}》》

[java] view
plaincopy

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：

[java] view
plaincopy

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

*/

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:

[java] view
plaincopy

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();

}

}

}
