在选项卡视图下显示列表

我正在尝试在选项卡式视图的选项卡下显示自定义列表。 我的代码在这里：

**and AppAdapter.java:**

    import android.view.ViewGroup;
    import android.widget.ArrayAdapter;
    import android.widget.TextView;


    public class AppAdapter extends ArrayAdapter<App> {

             private ArrayList<App> items;

             public AppAdapter(Context context, int textViewResourceId, ArrayList<App> items) {
                     super(context, textViewResourceId, items);
                     this.items = items;
             }

             @Override
             public View getView(int position, View convertView, ViewGroup parent) {
                     View v = convertView;
                     if (v == null) {
                         LayoutInflater vi = (LayoutInflater)getContext().getSystemService(Context.LAYOUT_INFLATER_SERVICE);
                         v = vi.inflate(R.layout.app_row, null);
                     }
                     App app = items.get(position);
                     if (app != null) {
                             TextView tt = (TextView) v.findViewById(R.id.toptext);
                             TextView bt = (TextView) v.findViewById(R.id.bottomtext);
                             if (tt != null) {
                                   tt.setText("Name: "+app.getAppName());                            }
                             if(bt != null){
                                   bt.setText("Status: "+ app.getAppDesc());
                             }
                     }
                     return v;
             }
    }

但列表的结果是： 我看不到整个列表，它以某种方式停止显示列表的其余部分。 请帮忙！！ 谢谢，布什
