我收到此错误:
Caused by: java.lang.RuntimeException:
Your content must have a ListView whose id attribute is 'android.R.id.list'
这是 HomeScreen.java:
public class HomeScreen extends ListActivity {
String TAG = AppConstants.TAG;
@Override
protected void onCreate(Bundle savedInstanceState){
super.onCreate(savedInstanceState);
setContentView(R.layout.home);
CBasicInfo basicinfo_data[] = new CBasicInfo[]
{
new CBasicInfo("Projet A", 1, new Date()),
new CBasicInfo("Projet A", 2, new Date()),
new CBasicInfo("Projet A", 3, new Date()),
new CBasicInfo("Projet A", 4, new Date()),
new CBasicInfo("Projet A", 5, new Date())
};
BasicInfoAdapter adapter = new BasicInfoAdapter(this, R.layout.home_screen_list_item, basicinfo_data);
ListView list_view = (ListView)findViewById(R.id.lvSavedProjects);
list_view.setAdapter(adapter);
}
}
这里是我的适配器 BasicInfoAdapter.java:
public class BasicInfoAdapter extends ArrayAdapter<CBasicInfo>{
Context context;
int layoutResourceId;
CBasicInfo data[] = null;
public BasicInfoAdapter(Context context, int layoutResourceId, CBasicInfo[] data) {
super(context, layoutResourceId, data);
this.layoutResourceId = layoutResourceId;
this.context = context;
this.data = data;
}
@Override
public View getView(int position, View convertView, ViewGroup parent) {
View row = convertView;
BasicInfoHolder holder = null;
if(row == null)
{
LayoutInflater inflater = ((Activity)context).getLayoutInflater();
row = inflater.inflate(layoutResourceId, parent, false);
holder = new BasicInfoHolder();
holder.txtName = (TextView)row.findViewById(R.id.tvHomeScreenProjectName);
holder.txtPid = (TextView)row.findViewById(R.id.tvHomeScreenPid);
holder.txtDDate = (TextView)row.findViewById(R.id.tvHomeScreenDownloadDate);
row.setTag(holder);
}
else
{
holder = (BasicInfoHolder)row.getTag();
}
CBasicInfo bi = data[position];
holder.txtName.setText(bi.getName());
holder.txtPid.setText(bi.getId());
holder.txtDDate.setText(bi.getExportDate().toString());
return row;
}
static class BasicInfoHolder
{
TextView txtName;
TextView txtPid;
TextView txtDDate;
}
}
我的 home.xml 是:
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical" >
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="@string/lbl_saved_projects"
android:textAppearance="?android:attr/textAppearanceLarge" />
<ListView
android:id="@+id/lvSavedProjects"
android:name="android.app.ListFragment"
android:layout_width="match_parent"
android:layout_height="0dip"
android:layout_weight="0.86" />
<Button
android:id="@+id/bDownloadMoreProjects"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:text="@string/lbl_download_more_projects" />
</LinearLayout>
我到底做错了什么?
谢谢
