ListView三种实现方式

一、SimpleAdapter 

List> list = new ArrayList>();

Map map = new HashMap();

map.put("name", "xilige");
map.put("age", "48");

list.add(map);

map = new HashMap();
map.put("name", "wangwu");
map.put("age", "20");
list.add(map);

SimpleAdapter simple = new SimpleAdapter(
this, 
list, 
R.layout.list_item, 
new String[]{"name","age"}, 
new int[]{R.id.list_view_name,R.id.list_view_age});

listview.setAdapter(simple);

注 ：list_item.xml文件中  创建TextView（list_view_name）及 TextView（list_view_age）

二、ArrayAdapter 

List list = new ArrayList();

listview.setAdapter(new ArrayAdapter(this, android.R.layout.simple_list_item_1, list));

三、BaseAdapter 

1、方式一

List list = new ArrayList();

listview.setAdapter(new MyAdapter());

class MyAdapter extends BaseAdapter{


@Override
public int getCount() {
// TODO Auto-generated method stub
return list.size();
}

@Override
public View getView(int position, View convertView, ViewGroup parent) {
TextView textview = null;
if(null != convertView){
textview = (TextView) convertView;
}else
{
textview = new TextView(MainActivity.this);
}

textview.setTextSize(18);
textview.setText(list.get(position).toString());


return textview;
}

}

2、方式二

List list = new ArrayList();

listview.setAdapter(new MyAdapter());

class MyAdapter extends BaseAdapter{


@Override
public int getCount() {
return list.size();
}
@Override
public View getView(int position, View convertView, ViewGroup parent) {

LayoutInflater flater = MainActivity.this.getLayoutInflater();

View view = flater.inflate(R.layout.list_item, null);

TextView name = (TextView) view.findViewById(R.id.list_view_name);
TextView age = (TextView) view.findViewById(R.id.list_view_age);

Person p = list.get(position);

name.setText(p.getName());
age.setText(String.valueOf(p.getAge()));

return view;
}

}
