Question

我有这堂课：

public class list extends ListFragment {

    String[] countries = new String[] {
            "India",
            "Pakistan",
            "Sri Lanka",
            "China",
            "Bangladesh",
            "Nepal",
            "Afghanistan",
            "North Korea",
            "South Korea",
            "Japan"
    };

    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container,Bundle savedInstanceState) {
        ArrayAdapter<String> adapter = new ArrayAdapter<String>(inflater.getContext(), android.R.layout.simple_list_item_1,countries);
        setListAdapter(adapter);
        return super.onCreateView(inflater, container, savedInstanceState);
    }
}

更新：

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

android:layout_width="fill_parent"
android:layout_height="fill_parent"

            android:id="@android:id/tabs"
            android:layout_width="fill_parent"
            android:layout_height="wrap_content"></TabWidget>

        <FrameLayout

                android:layout_height="fill_parent">

                <fragment
                    android:id="@+id/all_dishes"
                    android:name="com.FoodOrderApp.list"
                    android:layout_width="fill_parent"
                    android:layout_height="wrap_content" />

            </LinearLayout>

            <LinearLayout
                android:id="@+id/tab2"
                android:layout_width="fill_parent"
                android:layout_height="fill_parent">

                <fragment
                    android:id="@+id/fav_dishes"
                    android:name="com.FoodOrderApp.list"
                    android:layout_width="fill_parent"
                    android:layout_height="wrap_content" />
            </LinearLayout>


        </FrameLayout>
    </LinearLayout>
</TabHost>

我希望在onCreateView方法中获取当前列表片段的id

Answer 1

您可以使用：

ListView lV = getListView();

要获取当前列表的ID，如果您要手动执行，请在 ListFragment 或 ListActivity 中获取android.R.id.list 。

如何在创建listfragment时获取资源ID
