我必须使用findViewByID methond在片段的问题。
在所说的纺丝器Spinner spinner = (Spinner) view.findViewById(R.id.tabsearchspinner_location);
总是空。 请参阅下面的代码。
public class FragmentTabSearch extends SherlockFragment implements OnItemSelectedListener {
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
// TODO Auto-generated method stub
View view = inflater.inflate(R.layout.fragment_tab_suggestions, container, false);
Spinner spinner = (Spinner) view.findViewById(R.id.tabsearchspinner_location);
ArrayAdapter<CharSequence> adapter = ArrayAdapter.createFromResource(this.getSherlockActivity(), R.array.spinner_location, android.R.layout.simple_spinner_item);
adapter.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);
spinner.setAdapter(adapter);
return view;
}
@Override
public void onItemSelected(IcsAdapterView<?> parent, View view,
int position, long id) {
// TODO Auto-generated method stub
}
@Override
public void onNothingSelected(IcsAdapterView<?> parent) {
// TODO Auto-generated method stub
}
}
布局文件是如下(PS:我已宣布中的值/ ids.xml文件中的ID / tabsearchspinner_location): <item type="id" name="tabsearchspinner_location"></item>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical" >
<Spinner
android:id="@id/tabsearchspinner_location"
android:layout_width="wrap_content"
android:layout_height="wrap_content" />
<ListView
android:id="@id/tablistview_search"
android:layout_width="match_parent"
android:layout_height="wrap_content" >
</ListView>
任何帮助表示赞赏!
