我想在我的应用程序中列出一个永无止境的清单。第一次，列表将显示 8，然后如果有更多数据，列表将根据列表的长度显示数据。
这是我的代码：
package com.example.main;
public class ResultRestoActivity extends ListActivity {
Context ctx;
List<Map<String,String>> listData = new ArrayList<Map<String,String>>();
List <Map<String,String>> list = new ArrayList<Map<String,String>>();
ListAdapter adap;
ListView lv;
Button btnLoadMore;
String bank,group,city,merchant,address,telpon,handphone,bb;
TextView tv_GName,tv_city,tv_merchant,tv_address,tv_telpon,tv_handphone,tv_bb;
ImageButton tabs_nearby, tabs_all;
int itemsPerPage = 4;
boolean loadingMore = false;
@Override
public void onCreate (Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
group = getIntent().getStringExtra("GROUP");
bank = getIntent().getStringExtra("BANK");
city = getIntent().getStringExtra("CITY");
merchant = getIntent().getStringExtra("MERCHANT");
address = getIntent().getStringExtra("ADDRESS");
telpon = getIntent().getStringExtra("TELPON");
handphone = getIntent().getStringExtra("HANDPHONE");
bb = getIntent().getStringExtra("BB");
ctx = this;
setContentView(R.layout.activity_restoresult);
tv_GName = (TextView)findViewById(R.id.tvRestoResult);
tv_GName.setText(""+group+"");
// tabs_all = (ImageButton)findViewById(R.id.imgbtn_semua);
// tabs_all.setOnClickListener(new OnClickListener() {
// @Override
// public void onClick(View v) {
// // TODO Auto-generated method stub
// tabs_all.setImageResource(R.drawable.tabs_semua_active);
//// loadStart();
// }
// });
// tabs_nearby = (ImageButton)findViewById(R.id.imgbtn_nearby);
// tabs_nearby.setOnClickListener(new OnClickListener() {
// @Override
// public void onClick(View v) {
// TODO Auto-generated method stub
// Toast.makeText(ctx, "Coming Soon", Toast.LENGTH_SHORT).show();
// tabs_nearby.setImageResource(R.drawable.tabs_terdekat_active);
// Intent i = new Intent(v.getContext(), NearbyComingSoon.class);
// startActivity(i);
// comingsoon();
// }
// });
list = (ArrayList<Map<String,String>>) getIntent().getSerializableExtra("LIST");
for(int i=0;i<list.size(); i++){
final Map<String, String> map = list.get(i);
for (Map.Entry<String, String> entry : map.entrySet()) {
// String key = entry.getKey();
final String value = entry.getValue();
if(value.equalsIgnoreCase(bank)){
listData.add(list.get(i));
}
}
}
lv = getListView();
adap = new ListAdapter(listData);
lv.setAdapter(adap);
lv.setOnItemClickListener(new OnItemClickListener() {
@Override
public void onItemClick(AdapterView<?> arg0, View v, int position,
long arg3) {
merchant = ((TextView) v.findViewById(R.id.tv_merchantname)).getText()
.toString();
Intent i = new Intent(ResultRestoActivity.this, DetailRestoActivity.class);
i.putExtra("GROUP", group);
i.putExtra("CITY", city);
i.putExtra("MERCHANT", merchant);
i.putExtra("ADDRESS", address);
i.putExtra("TELPON", telpon);
i.putExtra("HANDPHONE", handphone);
i.putExtra("BB", bb);
startActivity(i);
}
});
View footerView = ((LayoutInflater) this.getSystemService(Context.LAYOUT_INFLATER_SERVICE)).inflate(R.layout.listfooter, null, false);
this.getListView().addFooterView(footerView);
this.setListAdapter(adap);
this.getListView().setOnScrollListener(new OnScrollListener() {
@Override
public void onScrollStateChanged(AbsListView view, int scrollState) {
// TODO Auto-generated method stub
}
@Override
public void onScroll(AbsListView view, int firstVisibleItem,
int visibleItemCount, int totalItemCount) {
// TODO Auto-generated method stub
int lastInScreen = firstVisibleItem + visibleItemCount;
if((lastInScreen == totalItemCount) && !(loadingMore)){
Thread thread = new Thread(null, loadMoreListItems);
thread.start();
}
}
});
Thread thread = new Thread(null, loadMoreListItems);
thread.start();
}
private Runnable loadMoreListItems = new Runnable() {
@Override
public void run() {
// TODO Auto-generated method stub
loadingMore = true;
// list = (ArrayList<Map<String,String>>) getIntent().getSerializableExtra("LIST");
try {
Thread.sleep(1000);
} catch (Exception e) {
// TODO: handle exception
}
for(int i=0;i<itemsPerPage; i++){
final Map<String, String> map = list.get(i+2);
for (Map.Entry<String, String> entry : map.entrySet()) {
// String key = entry.getKey();
final String value = entry.getValue();
if(value.equalsIgnoreCase(bank)){
listData.add(list.get(i));
}
}
}
adap = new ListAdapter(listData);
lv.setAdapter(adap);
}
};
}
但是这段代码仍然出错。这里是它的错误信息：
android.view.ViewRootImpl$CalledFromWrongThreadException: Only the original thread that created a view hierarchy can touch its views.
我需要你的建议、链接、评论和你的所有帮助......
