我想在我的片段裏放一個簡單的listview。當我按原樣運行時出現錯誤。我並不期望它能夠與我現有的代碼一起工作,但我不確定該從哪裏去。任何幫助將不勝感激!如何在Android中的片段內放置一個listview?
我的代碼:
public class Tab1Fragment extends ListFragment {
ListView listView;
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
LinearLayout theLayout = (LinearLayout) inflater.inflate(R.layout.tab1, container, false);
listView = (ListView)theLayout.findViewById(R.id.ListView01);
return theLayout;
}
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
// Use an existing ListAdapter that will map an array
// of strings to TextViews
setListAdapter(new ArrayAdapter<String>(getActivity().getApplicationContext(),
android.R.layout.simple_list_item_1, mStrings));
getListView().setTextFilterEnabled(true);
}
private String[] mStrings = {
"Action", "Adventure", "Animation", "Children", "Comedy", "Documentary", "Drama",
"Foreign", "History", "Independent", "Romance", "Sci-Fi", "Television", "Thriller"
};
}
我運行時錯誤:
