ListView BaseAdapter

自定義Adapter:

public View getView(int position, View convertView, ViewGroup parent) {

  ViewHolder viewHolder;

  if(convertView==null){

   convertView=LayoutInflater.from(context).inflate(R.layout.menu_item, null);

   viewHolder=new ViewHolder();

   viewHolder.img=(ImageView) convertView.findViewById(R.id.iv_menuImg);

   viewHolder.name=(TextView) convertView.findViewById(R.id.tv_menuName);

   viewHolder.price=(TextView) convertView.findViewById(R.id.tv_menuPrice);

   convertView.setTag(viewHolder);

  }

  viewHolder=(ViewHolder) convertView.getTag();

  viewHolder.img.setImageResource(arrayList.get(position).getMenuImg());

  viewHolder.name.setText(arrayList.get(position).getMenuName());

  viewHolder.price.setText(arrayList.get(position).getPrice()+"元");

  return convertView;

 }

 class ViewHolder{

  ImageView img;

  TextView name;

  TextView price;

 }

listView綁定Adapter:

initList(arrayList);

  listView1=(ListView) findViewById(R.id.listView1);

  MyAdapter myAdapter=new MyAdapter(TestAct4.this, arrayList);

  listView1.setAdapter(myAdapter);

  listView1.setOnItemClickListener(new OnItemClickListener() {

   @Override

   public void onItemClick(AdapterView<?> parent, View view, int position, long id) {

    setTitle(arrayList.get(position).getMenuName()+"  單價："

   +arrayList.get(position).getPrice()+"元");

   }

  });
