ListFragment中的自定义ArrayAdapter

我想创build一个自定义ArrayAdapter用于我的ListFragment 。 现在, ListFragment没有显示任何东西,除了TextView指出它是什么片段的编号。 我在我的适配器的getView()方法中放置了一个断点,并且没有被调用。 我search了不会被调用的原因,有些人似乎认为我的ListView是隐藏的,所以我试着将layout_height改为wrap_content ,但是这并不起作用。

另外,我一直在关注这个开发者页面的代码: http : //developer.android.com/reference/android/support/v4/app/FragmentPagerAdapter.html

ListFragment:

 public class HomeFragment extends ListFragment implements FragmentTitle { private int mNum = 0; private String mTitle = "Home"; private ListView mListView; private MyArrayAdapter mAdapter; @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); mNum = getArguments() != null ? getArguments().getInt("num") : 1; InfoContainer temp = new InfoContainer("test1", "test2"); mAdapter = new MyArrayAdapter(getActivity(), android.R.id.list, temp); } @Override public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) { View v1 = inflater.inflate(R.layout.fragment_pager_list, container, false); TextView tv = (TextView) v1.findViewById(R.id.text); tv.setText("Fragment #" + mNum); mListView = (ListView) v1.findViewById(android.R.id.list); return v1; } @Override public void onActivityCreated(Bundle savedInstanceState) { super.onActivityCreated(savedInstanceState); mListView.setAdapter(mAdapter); } @Override public void onListItemClick(ListView l, View v, int position, long id) { Log.i("HomeFragment", "Item clicked: " + id); } public CharSequence getTitle() { return mTitle; } } 

ArrayAdapter:

 public class MyArrayAdapter extends ArrayAdapter<InfoContainer> { Context mContext; InfoContainer data; public MyArrayAdapter(Context context, int textViewResourceId, InfoContainer temp) { super(context, textViewResourceId); mContext = context; this.data = temp; } @Override public View getView(int position, View convertView, ViewGroup parent) { View row = convertView; ViewHolder holder = new ViewHolder(); if(row == null) { LayoutInflater inflater = ((Activity)mContext).getLayoutInflater(); row = inflater.inflate(R.id.pager, parent, false); holder.v1 = (TextView) row.findViewById(R.id.listview_name); holder.v2 = (TextView) row.findViewById(R.id.listview_data); row.setTag(holder); } else { holder = (ViewHolder) row.getTag(); } InfoContainer info = data; holder.v1.setText(info.name); holder.v2.setText(info.text); return row; } public static class ViewHolder { TextView v1; TextView v2; } } 

fragment_pager_list.xml:

 <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="match_parent" android:layout_height="match_parent" android:orientation="vertical" android:background="#000000" > <TextView android:id="@+id/text" android:layout_width="match_parent" android:layout_height="wrap_content" android:gravity="center_vertical|center_horizontal" android:text="@string/hello_world" android:textAppearance="?android:attr/textAppearanceMedium" android:textColor="#FFFFFF" /> <ListView android:id="@android:id/list" android:layout_width="match_parent" android:layout_height="wrap_content" android:drawSelectorOnTop="false" android:background="@drawable/listview_background" android:textColor="#FFFFFF" /> 

我已经做了自定义的ArrayAdapters之前没有问题,所以有什么我失踪有关让他们使用ListFragment?
