importandroid.view.LayoutInflater;
importandroid.view.View;
importandroid.view.ViewGroup;
importandroid.widget.BaseAdapter;
importandroid.widget.ImageView;
importandroid.widget.ListView;
importandroid.widget.TextView;

publicclassMainActivityextendsActivity{
ListViewlistView;
String[]titles={"标题1","标题2","标题3","标题4"};
String[]texts={"文本内容A","文本内容B","文本内容C","文本内容D"};
int[]resIds={R.drawable.icon,R.drawable.icon,R.drawable.icon,R.drawable.icon};

@Override
protectedvoidonCreate(BundlesavedInstanceState){
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
this.setTitle("BaseAdapterforListView");
listView=(ListView)this.findViewById(R.id.MyListView);
listView.setAdapter(newListViewAdapter(titles,texts,resIds));
}

publicclassListViewAdapterextendsBaseAdapter{
View[]itemViews;

publicListViewAdapter(String[]itemTitles,String[]itemTexts,
int[]itemImageRes){
itemViews=newView[itemTitles.length];

for(inti=0;i<itemViews.length;++i){
itemViews[i]=makeItemView(itemTitles[i],itemTexts[i],
itemImageRes[i]);
}
}

publicintgetCount(){
returnitemViews.length;
}

publicViewgetItem(intposition){
returnitemViews[position];
}

publiclonggetItemId(intposition){
returnposition;
}

privateViewmakeItemView(StringstrTitle,StringstrText,intresId){
LayoutInflaterinflater=(LayoutInflater)MainActivity.this
.getSystemService(Context.LAYOUT_INFLATER_SERVICE);

//使用View的对象itemView与R.layout.item关联
ViewitemView=inflater.inflate(R.layout.listview_item,null);

//通过findViewById()方法实例R.layout.item内各组件
TextViewtitle=(TextView)itemView.findViewById(R.id.itemTitle);
title.setText(strTitle);
TextViewtext=(TextView)itemView.findViewById(R.id.itemText);
text.setText(strText);
ImageViewimage=(ImageView)itemView.findViewById(R.id.itemImage);
image.setImageResource(resId);

returnitemView;
}

publicViewgetView(intposition,ViewconvertView,ViewGroupparent){
if(convertView==null)
returnitemViews[position];
returnconvertView;
}
}
}
