我有3个 String []数组
DateArray [] = {17/09/2012，18/09/2012，19/09/2012};访问[] = {4，10，2};距离[] = {30，100，45}; 我要显示此数组中这样我所做的XML我只想填充这些3个值这是一个 ListActivity 一个ListView
我试图
我如何能做到这一点。
有关点击ListView中我使用
listView.setAdapter（新ObjAdapter（这一点，R.layout.claimlistview，物品））; listView.setOnItemClickListener（新AdapterView.OnItemClickListener（）{ @覆盖 公共无效onItemClick（适配器视图＆LT;＆GT;为arg0，ARG1查看，INT位置，长ARG3）{ 对象o = listView.getItemAtPosition（位置）; TextView的T1 =（的TextView）findViewById（R.id.ClaimDate）; 如果（T1！= NULL）{ ClaimListBean mSelected; INT IDX =位置; mSelected = m_adapter.getItem（IDX）; 字符串日期= mSelected.getDate（）; // StringTokenizer的令牌=新的StringTokenizer（日期，（）; //字符串第一= tokens.nextToken（）; //字符串第二= tokens.nextToken（）; 串访问= mSelected.getVisit（）; 字符串距离= mSelected.getDistance（）; //串EditedSecond = second.replace（），）; 意向意图=新意图（DRSTClaimList.this，DRSTClaimDetail.class）; intent.putExtra（日期，日期）; //intent.putExtra("Date，第一）; //intent.putExtra("Day，EditedSecond）; intent.putExtra（距离，距离）; intent.putExtra（访问，访问）; startActivity（意向）; } 解决方案
您需要与那些3的值创建对象，例如：
公共类的OBJ { 私人字符串日期; 私人字符串考察; 私人字符串距离; 公开的OBJ（日期字符串，字符串访问，字符串的距离）{ this.date =日期; this.visits =考察; this.distance =距离; } ... getter和setter的东西...} 然后你必须扩展arrayadapter类
公共类ObjAdapter扩展ArrayAdapter＆LT;＆的OBJ GT; { 私人上下文的背景下; 私人的ArrayList＆LT;＆的OBJ GT;项目; 公共ObjAdapter（上下文的背景下，诠释layoutResId，ArrayList的＆LT;＆的OBJ GT;数据）{ 超级（上下文，layoutResd，数据）; this.context =背景; this.items =数据; } @覆盖 公共查看getView（INT位置，查看convertView，父母的ViewGroup）{ 视图V = convertView; 如果（V == NULL）{ LayoutInflater VI =（LayoutInflater）getSystemService（Context.LAYOUT_INFLATER_SERVICE）; V = vi.inflate（R.layout.row，NULL）; } OBJ O = items.get（位置）; 如果（O！= NULL）{ TextView的日期=（TextView中）v.findViewById（R.id.date）; TextView的访问=（TextView中）v.findViewById（R.id.visits）; TextView的距离=（TextView中）v.findViewById（R.id.distance）; 如果（考察！= NULL）{ visits.setText（姓名：+ o.getVists（））; } 如果（日期！= NULL）{ date.setText（状态：+ o.getDate（））; } } 返回伏; } 在你到底有没有打电话给你的ListView :)
方法setListAdapter编辑：在标准活动是这样的（抱歉错误）：
公共无效的onCreate（捆绑icycle）{ super.onCreate（icycle）; 的setContentView（R.layout.listactivity）; ListView控件的ListView =（ListView控件）findViewById（R.id.listview）; ArrayList的＆LT;＆的OBJ GT;项目=新的ArrayList＆LT;＆的OBJ GT;（）; items.add（新的OBJ（日期，访问，）; items.add（新的OBJ（日期，访问，）： items.add（新的OBJ（日期，访问，）： listView.setListAdapter（新ObjAdapter（这一点，R.layout.list_row，物品））;} 在此，你在名单上有3项。

I have 3 String[] array
DateArray[]={"17/09/2012","18/09/2012","19/09/2012"};
Visit[]={"4","10","2"};
Distance[]={"30","100","45"};
I want to show this Array in a ListView like this i have made the XML i just want to populate these 3 values This is a ListActivity
i have tried to
How Can i do That
for Clicking the ListView i am using
listView.setAdapter(new ObjAdapter(this, R.layout.claimlistview, items));
listView.setOnItemClickListener(new AdapterView.OnItemClickListener() {
@Override
public void onItemClick(AdapterView<?> arg0, View arg1, int position, long arg3) {
Object o = listView.getItemAtPosition(position);
TextView t1=(TextView)findViewById(R.id.ClaimDate);
if(t1!=null){
ClaimListBean mSelected;
int idx=position;
mSelected=m_adapter.getItem(idx);
String Date=mSelected.getDate();
//StringTokenizer tokens = new StringTokenizer(Date, "(");
//String first = tokens.nextToken();
//String second = tokens.nextToken();
String Visit=mSelected.getVisit();
String Distance=mSelected.getDistance();
//String EditedSecond = second.replace(")","");
Intent intent=new Intent(DRSTClaimList.this,DRSTClaimDetail.class);
intent.putExtra("Date", Date);
//intent.putExtra("Date", first);
//intent.putExtra("Day", EditedSecond);
intent.putExtra("Distance", Distance);
intent.putExtra("Visit", Visit);
startActivity(intent);
}
解决方案
You need to create object with those 3 values, for example:
public class Obj{
private String date;
private String visits;
private String distance;
public Obj(String date , String visits, String distance){
this.date = date;
this.visits = visits;
this.distance = distance;
}
... getters and setters stuff...
}
and then you have to extend arrayadapter class
public class ObjAdapter extends ArrayAdapter<Obj>{
private Context context;
private ArrayList<Obj> items;
public ObjAdapter(Context context, int layoutResId, ArrayList<Obj> data) {
super(context, layoutResd, data);
this.context = context;
this.items = data;
}
@Override
public View getView(int position, View convertView, ViewGroup parent) {
View v = convertView;
if (v == null) {
LayoutInflater vi = (LayoutInflater)getSystemService(Context.LAYOUT_INFLATER_SERVICE);
v = vi.inflate(R.layout.row, null);
}
Obj o = items.get(position);
if (o != null) {
TextView date = (TextView) v.findViewById(R.id.date);
TextView visits = (TextView) v.findViewById(R.id.visits);
TextView distance = (TextView) v.findViewById(R.id.distance);
if (visits != null) {
visits.setText("Name: "+o.getVists()); }
if(date != null){
date.setText("Status: "+ o.getDate());
}
}
return v;
}
At the end you have to call method setListAdapter on your listView :)
EDIT: In standard activity is like this (sorry for bugs):
public void onCreate(Bundle icycle)
{
super.onCreate(icycle);
setContentView(R.layout.listactivity);
ListView listView = (ListView)findViewById(R.id.listview);
ArrayList<Obj> items = new ArrayList<Obj>();
items.add(new Obj("date", "visits"," ");
items.add(new Obj("date", "visits"," "):
items.add(new Obj("date", "visits"," "):
listView.setListAdapter(new ObjAdapter(this, R.layout.list_row, items));
}
After this, You got 3 items on the list.
