【移动应用开发技术】Android学习--ListView的使用(三)

使用SimpleAdapter创建ListView程序清单1<?xml

times=new

String[]{"2015/3/14

private

int[]

p_w_picpaths=new

int[]{R.drawable.touxiang,R.drawable.touxiang,R.drawable.touxiang};

@Override

protected

void

onCreate(Bundle

savedInstanceState)

{

super.onCreate(savedInstanceState);

setContentView(R.layout.classblog_tuijian);

//创建一个List集合

，list集合的元素是Map

List<Map<String,Object>>

listitems=new

ArrayList<Map<String,

Object>>();

for(int

i=0;i<contents.length;i++){

Map<String,Object>

listitem=new

HashMap<String,Object>();

listitem.put("content",contents[i]);

listitem.put("time",times[i]);

listitem.put("p_w_picpath",p_w_picpaths[i]);

listitems.add(listitem);

}

//创建一个SimpleAdapter

SimpleAdapter

simpleAdapter

=new

SimpleAdapter(this,listitems,R.layout.tuijian_item,

new

String[]{"content","time","p_w_picpath"},

new

int[]{R.id.textContent,R.id.textTime,R.id.p_w_picpathView3}

);

listView=(ListView)this.findViewById(R.id.mylist);

listView.setAdapter(simpleAdapter);

}

}程序清单3每一个列表项可根据自己需要进行定制<?xml
