最近项目中碰到GridView下拉刷新的问题，google不到现成的资料，故此用listview来实现GridView，对ListView而言下拉刷新就很多资料可参考了，这里就不再啰嗦了。

ListViewAdapter.java

[html] view plain copy

packagecom.example.grideview;
importjava.util.List;
importandroid.content.Context;
importandroid.util.Log;
importandroid.view.View;
importandroid.view.View.OnClickListener;
importandroid.view.ViewGroup;
importandroid.widget.BaseAdapter;
importandroid.widget.Button;
publicclassListViewAdapterextendsBaseAdapter{
privateList<String>list;
privateContextcontext;
publicListViewAdapter(Contextcontext){
this.context=context;
}
publicvoidsetData(List<String>list){
this.list=list;
}
@Override
publicintgetCount(){
//TODOAuto-generatedmethodstub
//每列两项
if(list.size()%2==0){
returnlist.size()/2;
}
returnlist.size()/2+1;
}
@Override
publicObjectgetItem(intposition){
//TODOAuto-generatedmethodstub
returnlist.get(position);
}
@Override
publiclonggetItemId(intposition){
//TODOAuto-generatedmethodstub
returnposition;
}
@Override
publicViewgetView(intposition,ViewconvertView,ViewGroupparent){
//TODOAuto-generatedmethodstub
ViewHolderviewHolder=null;
if(convertView==null){
viewHolder=newViewHolder();
convertView=View.inflate(context,R.layout.main,null);
viewHolder.button1=(Button)convertView
.findViewById(R.id.imageview1);
viewHolder.button2=(Button)convertView
.findViewById(R.id.imageview2);
convertView.setTag(viewHolder);
}else{
viewHolder=(ViewHolder)convertView.getTag();
}
//position计算两列的情况下：position*2+1多列依次类推
//第一列
Stringstring1=list.get(position*2);
viewHolder.button1.setText(string1);
viewHolder.button1.setTag(string1);
viewHolder.button1.setOnClickListener(newOnClickListener(){
@Override
publicvoidonClick(Viewv){
//TODOAuto-generatedmethodstub
Log.d("PAGE",v.getTag().toString());
}
});
//position计算两列的情况下：position*2+1多列依次类推
//第二列
if((position*2+1)<list.size()){
Stringstring2=list.get(position*2+1);
viewHolder.button2.setText(string2);
viewHolder.button2.setTag(string2);
viewHolder.button2.setOnClickListener(newOnClickListener(){
@Override
publicvoidonClick(Viewv){
//TODOAuto-generatedmethodstub
Log.d("PAGE",v.getTag().toString());
}
});
}else{
//此处可以用一张透明图片替换避免Grid布局混乱
viewHolder.button2.setVisibility(View.GONE);
}
returnconvertView;
}
classViewHolder{
privateButtonbutton1;
privateButtonbutton2;
}
}

其余代码就不贴了。可在此处下载 Demo。
