[英]How to put a listview inside of a fragment in android?
我試圖在片段中放入一個簡單的listview。 按原樣運行時出現錯誤。 我沒想到它可以與當前的代碼一起使用,但是我不確定從這里開始。 任何幫助將不勝感激!
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"
};
}
我的運行時錯誤:

您應該嘗試在onActivityCreated()
方法中調用setListAdapter()
。 這是因為Activity尚未完全由Fragment的onCreate()
方法創建,因為每個生命周期都略有不同。
這是一個類似的問題: Android片段onCreateView與onActivityCreated
您的片段中有幾個問題:
