android:id="@+id/Layout\_result"

列表项.xml

xmlns:android="http://schemas.android.com/apk/res/android"

android:id="@+id/listItem"

android:layout\_width="wrap\_content"

android:layout\_height="wrap\_content"

android:orientation="horizontal"

android:paddingLeft="10px"

android:paddingRight="10px"

android:paddingTop="5px"

android:paddingBottom="5px">

android:id="@+id/result\_item\_name\_object"

android:layout\_height="wrap\_content"

android:singleLine="false"

android:gravity="left"

android:textSize="18sp" android:layout\_width="260px">

android:id="@+id/result\_item\_distance"

主代码:

ListView resultList = (ListView)findViewById(R.id.resultListView);

ItemAdapter m\_adapter = new ItemAdapter(this, R.layout.list\_item, itemsFound);

resultList.setAdapter(m\_adapter);

viewItems = new Runnable()\{

@Override

public void run() \{

searchItems();

\};

Thread thread = new Thread(null, viewItems, "Searching");

thread.start();

private class ItemAdapter extends ArrayAdapter\{

private ArrayList items;

public ItemAdapter(Context context, int textViewResourceId,

ArrayList objects) \{

super(context, textViewResourceId, objects);

this.items = objects;

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.list\_item, null);

Item item = (Item) items.get(position);

if (item != null)\{

TextView resName = (TextView) v.findViewById(R.id.result\_item\_name\_object);

TextView resDistance = (TextView) v.findViewById(R.id.result\_item\_distance);

if (resName != null)\{

resName.setText(item.name);

if (resDistance != null)\{

resDistance.setText(item.distance);

return v;

private Runnable returnRes = new Runnable() \{

@Override

public void run() \{

if(itemsFound != null && itemsFound.size() > 0)\{

m\_adapter.notifyDataSetChanged();

int count = itemsFound.size();

for(int i=0; i < count; i++)

m\_adapter.add(itemsFound.get(i));

m\_ProgressDialog.dismiss();

m\_adapter.notifyDataSetChanged();

\};

第一个问题是result.xml布局窗口中的“AdapterView不支持addView(View,LayoutParams)”,但当我从resut.xml中的listview清除textview时,问题消失了,但出现了一个新问题:

11-10 10:39:42.623: ERROR/AndroidRuntime(720): android.content.res.Resources$NotFoundException: String resource ID \#0x304

11-10 10:39:42.623: ERROR/AndroidRuntime(720): at android.content.res.Resources.getText(Resources.java:200)

/\*and so on\*/
